Listing the image formats that can be read and written

This Java tip illustrates a method of listing the image formats that can be read and written. The complete list of available readable and writeable formats can be retrieved by calling ImageIO.getReaderFormatNames() and ImageIO.getWriterFormatNames(). By default, the javax.imageio package can read GIF, PNG, and JPEG images and can write PNG and JPEG images.


// Get list of unique supported read formats
String[] formatNames = ImageIO.getReaderFormatNames();
formatNames = unique(formatNames);
// e.g. png jpeg gif jpg

// Get list of unique supported write formats
formatNames = ImageIO.getWriterFormatNames();
formatNames = unique(formatNames);
// e.g. png jpeg jpg

// Get list of unique MIME types that can be read
formatNames = ImageIO.getReaderMIMETypes();
formatNames = unique(formatNames);
// e.g image/jpeg image/png image/x-png image/gif

// Get list of unique MIME types that can be written
formatNames = ImageIO.getWriterMIMETypes();
formatNames = unique(formatNames);
// e.g. image/jpeg image/png image/x-png

// Converts all strings in 'strings' to lowercase
// and returns an array containing the unique values.
// All returned values are lowercase.
public static String[] unique(String[] strings) {
Set set = new HashSet();
for (int i=0; i String name = strings[i].toLowerCase();
set.add(name);
}
return (String[])set.toArray(new String[0]);

Risks to e-mail

There are several inherent risks in the way e-mail functions. When you send e-mail to a recipient, it travels to an SMTP (Simple Mail Transfer Protocol) server either directly (if you’re using an e-mail client such as Outlook) or via a Web server (if you’re using Web-based mail, such as Hotmail). The recipient will receive your e-mail directly from the SMTP server or via a Web server.
During this journey, any unauthorized person can access your messages by exploiting vulnerabilities on the SMTP or Web servers. Your messages can be read and copied by anyone who has access to the computers and networks through which your messages travel. In fact, authorized system administrators on the SMTP servers can also read, copy, save, delete, and modify your messages before sending them on.
During this ‘eavesdropping’, it may be possible to gain access to your usernames and passwords. The mischief-monger can then wreak havoc by sending messages on your behalf. You may also receive messages from known e-mail IDs that have been created and sent by unauthorized users; such messages usually contain viruses, Trojans or ask you to reply to the message with sensitive personal information, such as bank-account or credit-card details.
What’s more, mail backups on SMTP servers store the e-mail in plain text; sometimes, messages that you sent or received years ago are easily available on these backups, long after you have deleted them.
The issues with e-mail are, therefore, manifold - the sender’s e-mail ID may be stolen and misused, without the recipient knowing about it; messages may be intercepted; or messages may be stored such that their content is easily accessible.
Encryption, digital signatures, and digital certificates are some ways of securing e-mail from these threats.

Digital IDs and Signatures

Having a digital ID enables you to add another layer of security to your e-mail via digital signatures. A digital ID ties your identity information—name or e-mail ID, for instance—with your public key.
When you use this ID to digitally sign your messages, a part of your message is encrypted with your private key, so that the recipient knows that the message came from you; if you encrypt the message in addition, then the signature and the message are encrypted with your public key. This enables the recipient to know whether the message has been accessed or modified en route.
Digital IDs are provided via e-mail certificates, which are usually issued by external certification authorities (CAs). In organizations, sometimes, the administrator of your Exchange Server generates these certificates for users.
If you use Outlook, you can get e-mail certificates from CAs. Some like Comodo offer these free of charge for personal use; for commercial use, different schemes are available from various CAs. source:India syndicate

Concept of 3G

There will be a wide range, from simple single-application devices such as voice-only phones, to multi-purpose communicators capable of handling several voice, data and video services in parallel.

To date, the "terminal" for accessing mobile services has been the mobile phone. With the coming of 3G, we can expect to see a broadening of this concept to include a whole host of new terminals. These will be both general-purpose computing and communications devices, and devices with more specific purposes to serve particular marker segments. There will still be recognizable mobile phones. But many of these will have larger screens to display Internet pages or the face of the person being spoken to. There will be smaller "smart-phones" with limited web browsing and e-mail capabilities. The addition of mobile communications capabilities to laptop and palmtop computers will speed up the convergence of communications and computing, and bring to portable computing all the functions and features available on the most powerful desktop computers. There will be videophones, wrist communicators, palmtop computers, and radio modem cards for portable computers. Innovative new voice based interfaces will allow people to control their mobile communication services with voice commands.

We will also see the integration of 3G into a very wide range of devices and products other than user terminals. For example, the "telephone-on-a-card" will allow mobile services to be built into business equipment, vehicles and household appliances, for dedicated applications. Devices such as phones, computers and digital cameras will also be able to communicate with each other using short-range radio. Digital cameras will be able to use wide-area radio communications in real time and reduce the need for bulky memory and other components.

Saving a BufferedImage to a PNG file

You can save a BufferedImage object using write method of the javax.imageio.ImageIO class. The signutaure of the method is like this:
public static boolean write(RenderedImage im,
String formatName,
File output)
throws IOException

Here im is the RenderedImage to be written, formatName is the String containg the informal name of the format (e.g. png) and output is the file object to be written to. An example usage of the method for PNG file format is shown below:
ImageIO.write(image, "png", file);

You can also use getReaderFormatNames method of the same class to learn available informal format names understood by the current set of registered readers.

Protecting Worksheet Names in Excel!!

If you are developing workbooks for others to use, you may want your worksheets to retain whatever names you give them. Excel normally allows users to change worksheet names, as desired. If you don't want them to change, the only way to prevent it is to lock the workbook. You can take these steps if you are using a version of Excel prior to Excel 2007:

1.Display the Review tab of the ribbon.
2.Click Protect Workbook in the Changes group. Excel displays the Protect Structure and Windows dialog box. (Click here to see a related figure.)
3.Make sure that the Structure check box is selected.
4.Enter a password in the Password box.
5.Click on OK. Excel displays the Confirm Password dialog box, prompting you to reenter the password.
6.Reenter the password and click on OK.

The user can no longer make changes to the names of the worksheet tabs, nor to anything else that affects the structure of the workbook. (For instance, they cannot enter new worksheets or delete existing ones.)

If you want to protect the workbook under the control of a macro, then you can use this code:
ActiveWorkbook.Protect Password:="MyPassword", Structure:=TrueAll you need to do is provide password you want to use in place of the "MyPassword" example.

IIS 6 – Viva the Application Pool

IIS 6 changes the processing model significantly in that IIS no longer hosts any foreign executable code like ISAPI extensions directly. Instead IIS 6 always creates a separate worker process – an Application Pool – and all processing occurs inside of this process, including execution of the ISAPI dll. Application Pools are a big improvement for IIS 6, as they allow very granular control over what executes in a given process. Application Pools can be configured for every virtual directory or the entire Web site, so you can isolate every Web application easily into its own process that will be completely isolated from any other Web application running on the same machine. If one process dies it will not affect any others at least from the Web processing perspective.

In addition, Application Pools are highly configurable. You can configure their execution security environment by setting an execution impersonation level for the pool which allows you to customize the rights given to a Web application in that same granular fashion. One big improvement for ASP.NET is that the Application Pool replaces most of the ProcessModel entry in machine.config. This entry was difficult to manage in IIS 5, because the settings were global and could not be overridden in an application specific web.config file. When running IIS 6, the ProcessModel setting is mostly ignored and settings are instead read from the Application Pool. I say mostly – some settings, like the size of the ThreadPool and IO threads still are configured through this key since they have no equivalent in the Application Pool settings of the server.

Because Application Pools are external executables these executables can also be easily monitored and managed. IIS 6 provides a number of health checking, restarting and timeout options that can detect and in many cases correct problems with an application. Finally IIS 6’s Application Pools don’t rely on COM+ as IIS 5 isolation processes did which has improved performance and stability especially for applications that need to use COM objects internally.

Encrypting e-mail

Encryption means scrambling the text of your message to a seemingly gibberish combination of letters and numbers, so that anyone who reads it en route can make no sense of it. Only the recipient is able to decrypt the message.
Using public keys is the most common form of encryption. This requires the use of two keys - a public key and a private key. The private key resides on your computer and you share the public key with the recipients to which you wish to send encrypted messages. When you wish to send the message, you encrypt it with the public key. On the other end, the recipient needs its own private key and your public key to decrypt the message. Since the message is decrypted using your public key, it proves that you sent the message. You can encrypt messages as well as attachments.
If you use Outlook as your e-mail client, encryption is built into it via digital IDs, which enable you to encrypt your message and digitally sign it as well. You can also use the popular public-key encryption system, PGP (Pretty Good Privacy), with Outlook itself and with other e-mail clients. This utility is available as freeware on Source: www.pgpi.org.

IIS 6 – Viva the Application Pool

Although IIS 6 application pools are separate EXEs, they are highly optimized for HTTP operations by directly communicating with a kernel mode HTTP.SYS driver. Incoming requests are directly routed to the appropriate application pool. InetInfo acts merely as an Administration and configuration service – most interaction actually occurs directly between HTTP.SYS and the Application Pools, all of which translates into a more stable and higher performance environment over IIS 5. This is especially true for static content and ASP.NET applications.

An IIS 6 application pool also has intrinsic knowledge of ASP.NET and ASP.NET can communicate with new low level APIs that allow direct access to the HTTP Cache APIs which can offload caching from the ASP.NET level directly into the Web Server’s cache. In IIS 6, ISAPI extensions run in the Application Pool worker process. The .NET Runtime also runs in this same process, so communication between the ISAPI extension and the .NET runtime happens in-process which is inherently more efficient than the named pipe interface that IIS 5 must use. Although the IIS hosting models are very different the actual interfaces into managed code are very similar – only the process in getting the request routed varies a bit.

AS/400 Tip 2

Data Areas are chunks of memory to hold a few control values. A typical use is to keep track of the last invoice number for a system.

To create a data area, use the command
CRTDTAARA (Create Data Area).
For example, to create a 100 character data area named LASTINV#:
CRTDTAARA DTAARA(MYLIB/LASTINV#) TYPE(*CHAR) LEN(100)
Now, load the first 10 positions with the value "AA12345678" with the CHGDTAARA (Change Data Area) command
CHGDTAARA DTAARA(QTEMP/LASTINV# (1 10)) VALUE('AA12345678')
Look at the value of the data area with DSPDTAARA (Display Data Area):
DSPDTAARA MYLIB/LASTINV# A CL program can retrieve the value with RTVDTAARA.
An RPG program uses the "IN" operation to retrieve the value and the "OUT" operation to change it. There is a special Data Area known as the LDA (Local Data Area). It is 1024 characters and is associated with a job. So, any display session has an LDA associated with it. Not only that, when a job is submitted to run in batch, the LDA gets sent with the job so the batch job can read the LDA of the display session that submitted it.

View and change your LDA by using *LDA instead of a data area name:
DSPDTAARA *LDA CHGDTAARA DTAARA(*LDA (1 10)) VALUE('AA12345678')
Using the LDA is considered by many to be an obsolete style. Older programs use the LDA to store and pass parameters.

AS/400 Tip 1

Converting an AS/400 database file to a CSV file
You may find yourself in a situation where you want to run a Query on a file, save the information to a database,and then convert that information to a Comma Separated Variable (CSV) file. This is especially true when you need the data to be used in a "spread sheet" format like Excel.
The simplest way to do this is to copy the information from the data file to your newly created CSV file.

Enter this command:
CPYTOIMPF FROMFILE(*LIBL/DTAFIL) TOFILE(USER999/CSVPC)
Hit Enter, and then again 3 times and you have now created a Comma Separated Variable (CSV) File.
Remember that you need a 'destination file' before you can use this command. To create a 'destination file', you will need to use the Create Physical File command. To create a file named CSVPC that is 200 characters in length, type in the command:
CRTPF FILE(USER999/CSVPC)
Hit F4 to prompt the command, and type in the record length you need, for Member, be sure to name it CSV.

CHARSET Statement

The CHARSET statement specifies the contents of one or more of the character segments of a library character set module. A library character set module consists of header information followed by 64 character segments. Each character segment contains the character's 6-bit code for a WCGM location, its scan pattern, and its pitch. You can use the INCLUDE statement to copy an entire module, minus any segments deleted using the DELSEG keyword. In addition, you can use the CHARSET statement to select character segments from any module named with a library character set ID or the GCM keyword. The CHARSET statement can also specify the scan pattern and characteristics for a new character.

The CHARSET statement must always be followed by a NAME statement, another CHARSET statement, or one or more data statements. The CHARSET statement must be preceded by an OPTION statement with the DEVICE parameter if you want to create library character set modules in the 3800 Model 3 compatibility mode module format. The CHARSET statement can be preceded by an INCLUDE statement. More than one CHARSET statement can be coded in the operation group. The operation group can include CHARSET statements that select characters from existing modules and CHARSET statements that create new characters. The CHARSET statement, preceded by an INCLUDE statement, can be used to delete one or more segments from the copy of an existing module to create a new module.

A CHARSET statement with no operands specified, followed by a NAME statement that identifies a library character set module, is used to format and print the module.

INCLUDE Statement

When an IEBIMAGE operation group is used to create a new module, the INCLUDE statement can identify an existing image library module to be copied and used as a basis for the new module. When the operation group is used to update an image library module, the INCLUDE statement identifies the module to be referred to and must be specified.

When the INCLUDE statement is coded in an operation group, it must precede any FCB, COPYMOD, TABLE, GRAPHIC, or CHARSET statements.

Only one INCLUDE statement should be coded for each operation group. If more than one is coded, only the last is used; the others are ignored.

You can code an INCLUDE statement for an FCB module only if the DEVICE=4248 parameter is specified on the OPTION statement. Either 3211 format or 4248 format FCBs may be included. IEBIMAGE tries to locate the 4248 format FCB first; if it is not found, IEBIMAGE looks for the 3211 format. You cannot copy a 3800 FCB module with INCLUDE.

Different ways to shut down your PC

There are so many different ways to turn off your Windows XP computer, let's look at some of them:
1. The standard approach - click the Start Button with your mouse, then select the Turn Off menu and finally click the Turn Off icon on the Turn Off computer dialog.
2. Press Ctrl+Esc key or the Win key and press U two times - the fastest approach.
3. Get the Shutdown utility from Download.com - it adds the shut down shortcuts for you. Else create them yourself using approach (4).
4. Create a shutdown shortcut on your desktop. Right click on the desktop, choose New Shortcut and type shutdown -s -t 00 in the area where you are asked to specify the location of the program file. Now you can just double click this icon to turn off the computer. The best location would be your quick launch bar.
5. Press the Win key + R key to open the run window. Type shutdown -s -t 00. [s means shutdown while t means the duration after which you want to initiate the shutdown process]. If some open processes or application won't let you turn off, append a -f switch to force a shutdown by closing all active processes.
6. Win+M to minimize all windows and then Alt+F4 to bring the Turn Off computer dialog.
7. Open Windows Task manager (by right clicking the Windows Task bar or Alt+Ctrl+Del) and choose Shut down from the menu. Useful when the Windows are not responding.
8. open task manager - click on shutdown - hold the ctrl key and click on Turn off, pc will be turned off in 3 secs. Fastest method other than hard shutdown.

Verifying a connection between the AS/400 and RPM

To make a TCP/IP connection to RPM, the TELNET command may be used. To verify a connection, perform the following telnet test.

• At the AS/400 command prompt, type TELNET and press F4
• In the Start TCP/IP TELNET (TELNET) screen, press F9 to view "all parameters."
• In the Remote System field, type *INTNETADR. Enter the IP address of the RPM host in the Internet Address field.
• Locate the Port parameter and enter 515, then press Enter.

If RPM is configured to relax the 'port in range' requirement, this will input-inhibit the session if a connection is made. Close RPM (Windows 9x) or restart the RPM service (RPM Elite/Select) to release the AS/400 session. Then restart RPM and check the RPM log for new message.

If RPM is not configured this way, a new message should be displayed in the RPM log stating:
Client port xxxx out of range
Although this message is a warning, it verifies that a connection was made to RPM at port 515.

Applying Regular Expressions on the contents of a file

This Java tip illustrates a method of applying Regular Expressions on the contents of a file. The matching routines in java.util.regex require that the input be a CharSequence object. This tip implements a method that efficiently returns the contents of a file in a CharSequence object.

public CharSequence fromFile(String filename) throws IOException {
FileInputStream input = new FileInputStream(filename);
FileChannel channel = input.getChannel();
ByteBuffer bbuf = channel.map(FileChannel.MapMode.READ_ONLY, 0, (int)channel.size());
CharBuffer cbuf = Charset.forName("8859_1").newDecoder().decode(bbuf);
return cbuf;
}

Here is sample code that uses the above method:
try {
Pattern pattern = Pattern.compile("pattern");
Matcher matcher = pattern.matcher(fromFile("infile.txt"));
while (matcher.find()) {
String match = matcher.group();
}
} catch (IOException e) {
}

Divergence Index in Distributed Databases with Replication

This post is basically a synopsis of database architecture/design I recently worked on for a RFP response.

Suppose that in a geographically distributed database deployment scenario, two databases (with copies of the same data) at geographically separated locations accept DMLs simultaneously. To ensure data convergence, these databases also engage in asynchronous bi-directional replication with each other along with standard measures like conflict detection and resolution. However, since the replication overhead is finite, at any instant in time, it is acceptable that a particular record in the database at one site is not available in the database at the other site. Let's assume that the total time taken for a record (after it is updated at the database at one site) to appear in the database at the other site is T. Thus T will comprise of the capture overhead at the source site, the network latency across sites and the apply overhead at the destination site. A very important consideration here is that the capture and apply processes at the databases are assumed to be not specific to tables - meaning that replication across any given pair of tables will undergo a total lag of T. This kind of an arrangement requires strict vigil on the replication throughput to ensure that severe data divergence does not occur. We need to develop metrics to quantify which site 'lags' and by how much. Let's give this metric a jazzy name - the 'Divergence Index' a.k.a DI. I'll put forward a simple approach toward calculating and interpreting the value of DI.

Oracle's documentation on Streams replication discusses the concept of a 'heartbeat table' that is something like this: assume that using some mechanism like NTP (network time protocol), the system date of the databases at both sites are synchronized. At both databases, we create a table 'heartbeat' with just two columns - a siteID (varchar) and a timestamp (defaults to the current time). Using a scheduled recurring job, we update (or insert) a record in this table. Thus this table will contain a record with values corresponding to that site's ID and the timestamp of the last update. Now, this table is configured as a publisher as well as a subscriber to the corresponding table of the other database. Therefore, at any instant in time, this table will tell us (i)when it was locally updated last and (ii)the timestamp of the most current update at the other database that has appeared locally. Neat, isn't it?. Note that this concept is nowhere specific to Oracle - you could do this with any decent RDBMS. So, what does this heartbeat table have to do with calculating DI?
Let's see.
DI measured at site A can be calculated as
DI(A) =( t(A) - t(B) ) / T
where,t(A) represents the highest value of the timestamp column with siteID = A andt(B) represents the highest value of the timestamp column with siteID = B

There are some very interesting and useful deductions possible from this. But before that, remember that the heartbeat tables are merely instrumented tables. The actual replication load is generated by other tables that are configured for application data. So, the updates on the heartbeat tables alone can never be of significance as far as calculating DI is concerned. Agreed? great!

Quite obviously, the ideal value of DI is 1.If DI > 1, either records from one database are taking longer than T to get applied at the other database or the scheduled update of the heartbeat table is not happening at the other site.If DI <> DI(B), updates from A reach B mach faster than they reach A from B - this means that the database at site B is relatively much more loaded with DMLs than A. This indicates that (possibly) the load balancing across databases is improper.

For DI to be an useful metric, it should be measured at an interval not less than the heartbeat update interval. A lot can be achieved by maintaining a history of the value of DI and charting them over a period of hours, days and weeks. For example, if you notice that over a period of time, the DI at both sites keep increasing, then you could additionally see, for a given site, say A, how the value of t(B) has changed over the same period. In the worst case, if t(B) has not changed (thereby DI has increased), it clearly means that A has stopped applying B's updates. If you notice similar behaviour at the other site, you could well have a total replication breakdown.

How do touch-screen monitors recognize your touch?

There are three basic systems that are used to recognize a person's touch:

• Resistive
• Capacitive
• Surface acoustic wave

The resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact in that exact spot. The change in the electrical field is noted and the coordinates of the point of contact are calculated by the computer. Once the coordinates are known, a special driver translates the touch into something that the operating system can understand, much as a computer mouse driver translates a mouse's movements into a click or a drag.

In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

On the monitor of a surface acoustic wave system, two transducers (one receiving and one sending) are placed along the x and y axes of the monitor's glass plate. Also placed on the glass are reflectors — they reflect an electrical signal sent from one transducer to the other. The receiving transducer is able to tell if the wave has been disturbed by a touch event at any instant, and can locate it accordingly. The wave setup has no metallic layers on the screen, allowing for 100-percent light throughput and perfect image clarity. This makes the surface acoustic wave system best for displaying detailed graphics.

Siebel Mobile Client Debugging (Using Environment Variable)

We often come across errors and problems in Siebel application whose source cannot be easily identified. The standard spooling (/s method in the Target of the siebel exe) of queries is helpful many times.
But many other times there is need of more detailed logging than the one produced by simple spool.
I am listing an already existing very simple method of detailed logging here. Many of you might already be aware and using this method. I have always found this method gives me the exact source of the problem.
Ok so say you are getting an error, which cannot be linked to any configuration or any change you have done.

The steps to increase the logging detail are:
1. Right-Click My Computer select Properties.
2. Goto Advanced tab in the system properties.
3. Click on the environment variables
4. In the environment variables window, create a new system variable by clicking the New button
5. Add variable name as SIEBEL_LOG_EVENTS, the variable value can be 4 or 5. I would recommend using value 4 to start, if that is not helpful increase it to 5.
6. Restart the system after making this change.
7. Start the Siebel application, reproduce the problem which needs debugging.
8. Goto the Log folder in the Webclient directory, open the Siebel.log file (it will be large in size) present there.
9. Search for error in this log file.

IMPORTANT: Remember to remove this System Variable after you are done with your debugging, otherwise the size of the file will go on increasing and eat up you system memory. And yes you will again need to restart your system for the removal to take effect.

The size of the log file generated by using this method is quite large. It might become a bit difficult to handle these files if you are not used to handling very large files. You can use the wordpad to open these files which will be a little bit faster than usual notepad. I use a different method involving a file splitting tool. I will handle that in my next post.

Have a successful debugging!!!

How to print webpage without images and background colors?

Today tip will help you to print any website page in readable form (only text) without any extra graphics or images. There is a option on many websites "Print" to print a page in text format only, but if there is no print option then you can print out any webpage without its background colors and images using Internet Explorer setting.
Generally Internet Explorer setting "Print background colors and images" is disable, another advantage of printing webpage without background colors, you can speed up your printing process and also save printer ink. But important thing to always preview WebPages before you print, in Internet Explorer go to File menu, then click on Print Preview option.

1)To enable or disable print background colors option, open your system Internet Explorer.
2)Click the Tools menu and then go to Internet Options and open it. Here click the Advanced tab then scroll down to find the option Printing section.
3)Now check the option "Print background colors and images" then Apply and press Ok button.

SQL query tuning tips

“A solution is a state when you are tired of thinking“
This proverb indeed holds good for us in majority of the situations. The solutions that we provide to our customers have room for improvement by all means.
I have tried to list down a few of observations I made in my SQL performance tuning exercises. And I hope it is useful for the readers as well..

Using a Subset in SELECT:
It is always advisable to use the subset of fields that you require to process in a SELECT statement rather than *. Using a SELECT * consumes more resource and time in turn reducing the overall performance of the system.

IN / BETWEEN – Which clause works well for me ?
In case of a choice of using the IN or the BETWEEN clauses in the query, it is advantageous to use the BETWEEN clause, as it is much more efficient.
For example:
SELECT empid,empnameFROM employeeWHERE empid in (1,2,3,4,5,6,7,8,9,10);
is less efficient than:

SELECT empid,empnameFROM employeeWHERE empid BETWEEN 1 and 10;

Assuming there is a useful index on empid, the Query Optimizer can locate a range of numbers much faster (using BETWEEN) than it can find a series of numbers using the IN clause. As it is implied, checking for the list is going to go for N comparisons and BETWEEN would ideally be going for a check against the lower limit and the upper limit.
LIKE clauseIf LIKE is used in a WHERE clause, it is better to try to use one or more leading character in the clause, if at all possible.
For example :
Use
LIKE 'a%' not LIKE '%'
If a leading character is used in the LIKE clause, the query optimizer has the ability to potentially use an index to perform the query thereby, speeding performance. But if the leading character in a LIKE clause is a wildcard, a complete table scan has to be performed to process the query which in turn would bring down the performance.

DISTINCT clauseAt times this clause is added to every SELECT statement, even when it is not necessary. The DISTINCT clause should be used in SELECT statements when it is known that there would be duplicates and having duplicate rows in the result set would cause problems. DISTINCT would return the complete resultset to the temporary space, performs a SORT on the rows and eliminates the duplicates. So it uses the resources exhaustively.The DISTINCT clause reduces the efficiency if not used properly.

I would share some more in near future…Happy Reading !!!

Top 10 most useful secret moves in Office products!!!

Here are my top 10 most useful secret ninja moves to increase your productivity and win friends and lovers.

1: Format painter (Office)The Format Painter tool replicates the formatting from one part of a document to another. So instead of manually redoing all the formatting yourself, you can use the Format Painter. First, select the text whose formatting you want to replicate. Then, click the Format Painter toolbar button. Finally, select the text you want to imbue with the format. For bonus points, you can double-click the Format Painter button to replicate the formatting to multiple areas of the document!

2: Paragraph in/out/up/down (Office)You can easily move a paragraph in four directions by pressing Alt+Shift+[Arrow]. To increase or decrease the indentation level of a paragraph or bullet point, press Alt+Shift+Right and Alt+Shift+Left respectively. To move a paragraph up or down, press Alt+Shift+Up or Alt+Shift+Down. This works especially well in PowerPoint, where it's common to reorder bullet points or change indentation levels.

3: Increase or decrease font size (Office)To quickly increase the font size of selected text, press Ctrl+Shift+>. To decrease the size, press Ctrl+Shift+<. I find it easy to remember these keyboard shortcuts because the one with the greater-than symbol increases the font size while the less-than symbol decreases it.

4: Quick Access Toolbar (Office)Office 2007 has a Quick Access Toolbar that can be customized to include buttons for your favorite commands. The Quick Access Toolbar is in the top left corner of many Office applications. You customize it by clicking on the drop-arrow on its right.

5: Fill handle (Excel)Excel can auto-fill cells in eerily smart ways. Instead of manually typing a sequence in cells, you can simply type the first few values of the sequence and drag the fill handle to auto-fill the rest of the cells. The fill handle is the little black square at the lower right corner of a selected cell's border. Drag it to automatically fill adjacent cells.
If you drag the fill handle with only one cell selected, it will repeat that cell's value into adjacent cells. However, if you drag the fill handle with multiple cells selected, Excel is smart enough to figure out the series. For instance, in the following example, Excel will fill subsequent cells with the increasing series of odd numbers. This even works for other types of series, like dates and percentages.

6: Moving and copying cells by dragging selection borders (Excel)Quite possibly the most useful yet completely undiscoverable feature in Excel is the ability to move and copy cells by dragging selection borders.
For instance, to move row four between rows one and two, select row four and drag the selection border while holding down the Shift key in order to insert it in its new position. If you drag the border without holding down the Shift key, the selected cells will instead replace the cells you drop them on. Conversely, if you hold down Ctrl while dragging a selection border, the selected cells are copied to their new location.

7: Status bar statistics (Excel)The status bar in Excel shows handy statistics when multiple cells are selected. In Excel 2007, the status bar shows the selected cells' average, count, and sum. This is an easy way to quickly analyze data without authoring formulas.

8: Clear formatting (Word and PowerPoint)To remove formatting from selected text, press Ctrl+Spacebar.

9: Advanced field search (Outlook)In Outlook, you can quickly search through a mail folder by using the Instant Search box. In addition to searching for keywords, you can do a fielded search by prefixing your search text with a variety of field names.
For instance, the above example searches for all mail from people named "jimmy" sent in May with attachments that have "jpg" in the filename. I most often use this feature for two things: to easily find email from a specific person, and to find specific attachments.

10: Presenter view (PowerPoint)PowerPoint has for many years had a great feature called Presenter View, which allows you as the presenter to see a different view of the presentation from your audience. In Presenter View, your monitor shows not only the slides, but also your notes as well as the current elapsed time in the presentation. This makes giving a presentation far easier. To enable Presenter view, go to the Slide Show ribbon and check Use Presenter View. In that same section, you can also change the monitor which the presentation is shown on. One note: the Use Presenter View checkbox can only be checked if you already have a second monitor connected and enabled.

How handle exception in VB.NET ?

VB.NET has an inbuilt class that deals with errors. The Class is called Exception. When an exception error is found, an Exception object is created. The coding structure VB.NET uses to deal with such Exceptions is called the Try … Catch structure.

Syntax:TryCatch ex As ExceptionEnd TryThe Try word means "Try to execute this code". The Catch word means "Catch any errors here". The ex is a variable, and the type of variable it is an Exception object.

Example:Tryrt1.LoadFile ("C:\test10.txt", RichTextBoxStreamType.PlainText)Catch ex As Exception MsgBox (ex. Message) End Try

When you run your program, VB.net will try to execute any code in the Try part. If everything goes well, then it skips the Catch part. However, if an error occurs, VB.NET jumps straight to Catch and exception message in message box is executed.

In core java, Sub-classes can use super keyword to access the shadowed variables in super-classes. This technique allows for accessing only the immediate super-class. super.super is not valid. But casting the 'this' reference to classes up above the hierarchy will do the trick. By this way, variables in super-classes above any level can be accessed from a sub-class, since variables are resolved at compile time, when we cast the 'this' reference to a super-super-class, the compiler binds the super-super-class variable. But this technique is not possible with methods since methods are resolved always at runtime, and the method gets called depends on the type of object, not the type of reference variable. So it is not at all possible to access a method in a super-super-class from a subclass.

Example:
class A{
int c=1;
public void disp(){
System.out.println("A");
}
}

class B extends A{
int c=2;
public void disp(){
System.out.println("B");
}
}

class C extends B{
int c=3;
public void disp(){
System.out.println("C");
}

void demo(){
disp();
super.disp();
((A)this).disp();
System.out.println(c);
System.out.println(super.c);
System.out.println(((A)(this)).c);
}
}
public class G{
public static void main(String args[]){
new C().demo();
}
}

Output:-
C

That's it.You have discovered browser in oulook.How cool is it!!

Automate Web Service Testing the Right Way

Web services Web services are perfect candidates for automated testing. Compared with validating a UI, Web services Web services testing is quite simple: send a request, get a response, verify it. But it's not as easy as it may look. The main challenge is to identify the formal procedures that could be used for automated validation and verification. Other problems include dynamic data and differing request formats.

In the project our team was working on when this was written, there were many different Web services in need of testing. We needed to check not only the format of the request and response, but also the business logic, data returned by the services and the service behavior after significant changes were made in the architecture. From the very beginning we intended to automate as many of these tests as possible. Some of the techniques we used for automated verification of Web services functionality were as follows:

1.Response schema validation.
This is the most simple and formal procedure of response structure verification. There are free schema validators out there that can easily be built into automated scripts. However, schema validation is not sufficient of you also need to validate the Web services logic based on data returned from a service.

2.Comparison of the actual response with the expected response.
This is a perfect method for Web service regression testing because it allows for checking of both response structure and data within the response. After the successful manual validation, all valid responses are considered correct and saved for future reference. The response of all next versions of that Web service will then be compared with these template files. There is absolutely no need to write your own script for XML file comparison; just find the most suitable free tool and use it within your scripts. However, this method is not applicable when dealing with dynamic data or if a new version of Web services involves changes in the request structure or Web services architecture.

3.Check XML nodes and their values.
In the case of dynamic data, it can be useful to validate only the existence of nodes using XPath query and/or check the node values using patterns.

4.Validate XML response data against original data source.
As a “data source” it’s possible to use database, another service, XML files, non-XML files and in general, everything that can be considered a “data provider” for Web services. In combination with response schema validation, this method could be the perfect solution for testing any service with dynamic data. On the other hand, it requires additional skills to write your own scripts for fetching data from data source and comparing it with service response data.

5.Scenario testing.
This is used when the test case is not a single request but a set of requests sent in sequence to check Web services behavior. Usually the Web services scenario testing includes checking one Web service operation using another. For example, you can check that the CreateUser request works properly by sending a GetUser request and validating the GetUser response. In general, any of the above techniques can be used for Web services scenarios. Just be careful to send requests one after another in the correct order. Also be mindful of the uniqueness of test data during the test. The service might not allow you to create, for example, several users with the same name. It’s also common for one request in a sequence to require data from a previous response. In this case you need to think about storing that data and using it on the fly.

All of these techniques were implemented using a home-grown tool which we were using in our day-to-day work. Using that tool, we are able to automate about 70 percent of our test cases. This small utility that was originally created by developers for developers to cover typical predefined test conditions and gradually evolved into rather powerful tool. Having such a tool in your own organization could help your testing efforts well into the future.

W3C XML schema

XML schema is some other XML file which like DTD defines the type of document contents. Ths most famous is W3C XML schema but there could other means to declare the document. An example below shows generic XML schema content. Its root element is schema. Besides namespace-prefix mapping it can contains some set of attributes. Here we enable full-qualified names for elements and names only (without namespace prfixes) for attributes:

User Extension for gotoLabel command

We can use loop concepts in Selenium IDE:
Here is the user extension for gotoLabel command.

Selenium.prototype.doGotolabel = function( label ) {
if( undefined == gotoLabels[label] ) {
throw new Error( "Specified label '" + label + "' is not found." );
}
this.continueFromRow( gotoLabels[ label ] );
};

Increase your system performance

We all like the colourful Windows XP desktop. But this GUI (graphical user interface) is using a lot of system resources.You can optimize your MS Windows XP performance by disabling some of these visual effect.

To optimize your Windows XP:-
1. Click Start => Setting => Control Panel
2. Click System => Advance Tab
3. Click Settings button under Performance
4. Under Visual Effects tab, select Adjust for best performance (all the check boxes will be unchecked)
5. Scroll down the list and check “Use Common Tasks in Folders”
6. Click OK and OK again.

Your Windows XP will now has less colourful and lesser visual effect and it will look like MS Windows 98 but do not forget that your system performance would have been by increased now !!!

Example for gotoLabel command in Selenium IDE

Here is the example for gotoLabel command. When Selenium IDE encounters gotoLabel command, it searches for targetted label name in the rest of the script and passes the control to targetted Label and the executes the steps from Label command and skips the steps that are in between gotoLabel and Label commands. When the targetted label is not found it throws error.

Extension for Label Command:
Selenium.prototype.doLabel = function(){};

Example:

Restarting Windows Without Restarting Your PC!!!

A modern PC with Vista Home Edition takes about one and a half minutes to boot. An older machine with XP is about the same. That’s 30 seconds for the PC itself (the BIOS) to boot up, plus a minute for the Windows operating system to boot.

Sometimes, you need to reboot Windows (e.g. when installing new software), but there is no need to restart BIOS, too. However, the default is to reboot both. (That’s called doing a “cold boot,” rather than a “warm boot.”) There’s a trick that works on both XP and Vista to get it to do a warm boot instead, thus saving you 30 seconds per cycle.

The trick is to hold down the SHIFT key when invoking the restart.

Windows Vista:
Select Start, then hover over the right arrow that is to the right of the padlock icon until the pop-up menu appears that contains “restart” as one of it’s choices. Hold down the SHIFT key while clicking on the “restart” choice.

Windows XP:
Select Start. Select “Shut Down…”. Change the drop-down combo box under “What do you want the computer to do?” to “Restart”. Hold down the SHIFT key while clicking on the “OK” button.

Generating random number

First you would need to create an instance of Random class:
Random random = new Random();
Then, you can get your random number by calling:
int pick = random.nextInt(maxvalue);

This would return a value from 0 (inclusive) to maxvalue (exclusive).

For a more cryptographically strong pseudo random generator you may check out java.security.SecureRandom class. Here the caller may specify the algorithm name and (optionally) the package provider. Here is a sample code of using SecureRandom class:

SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
random.setSeed(seed);
int randInt = random.nextInt(maxvalue);

Nesting Master Pages

There are times where you may want to provide overall branding and appearance for your Web site, but at the same time provide sub-sites whose appearance must be consistent. To accomplish this, you need to nest one master page within another page, a process called "Nesting Master Pages". Nesting support is built-in, which means you don't have to do anything special to reap the advantages of nested master pages; a content page that uses a sub-master page will automatically receive content from all the master pages in the hierarchy.

Using the master pages architecture, you could implement a consistent look and feel across all the developer centers. For example, you can have the main MSDN page derive from a root master page. Each developer center can have its own master page, each of which uses the root master page as its master. This means a content page in any of the developer centers will inherit the root master page look and feel settings that provide overall MSDN branding, and will also inherit the custom look and feel specific to that developer center. This nested approach provides each developer center with the freedom to develop customized content while maintaining a consistent overall branding for the entire site.

Configuring Master Pages

So far, you've used the master attribute of the Page directive in the content pages to specify the name of the master page. Even though this approach works, it requires you or your developers to specify the master attribute in each page. You can eliminate that requirement by specifying the name of the master file in the web.config file under the pages element. After adding the entry to your web.config file, all the pages in that Web application will automatically use the designated master page. For example, the following web.config file entry specifies that all the pages in the Web application should use IntroMaster.master as their default master page.







You're not limited by setting the default master page in the web.config file. Even when you use this method to specify the name of a default master page, you can still override the global value by specifying a different master page in the master attribute of the Page directive. Any values you specify using the Page directive takes precedence over the web.config file entry.

To sum up, ASP.NET's new Master Pages feature provides a clean approach to encapsulate common functionality and content a centralized location, allowing other pages to inherit from those master pages, thereby greatly reducing the maintenance. Using master pages, you can also create one set of controls and code and apply the results to all your content pages. Apart from providing a fine-grained control over the layout of the content pages, master pages also expose an object model that allows you to access the master page controls, properties and methods from content pages.

Ten things you might not know about Google

1) The name Google is a spelling error. The founders of the site, Larry page and Sergey Brin, thought they were going for 'Googol.' Googol is the mathematical term for 1 followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, Mathematics and the Imagination by Kasner and James Newman. Google's play on the term reflects the company's mission to organize the immense amount of information available on the web. Initially, Larry and Sergey Brin called their search engine BackRub, named for its analysis of the of the web's "back links." The search for a new name began in 1997, with Larry and his officemates starting a hunt for a number of possible new names for the rapidly improving search technology.
2) The reason the google page is so bare is because the founder didn't know HTML and just wanted a quick interface. Due to the sparseness of the homepage, in early user tests they noted people just kept sitting staring at the screen, waiting for the rest to appear. To solve the particular problem the Google Copyright message was inserted to act as an end of page marker.
3) Google started as a research project by Larry page and Sergey Brin when they were 24 and 23 years respectively. Google's mission statement is to organize the world's information and make it universally accessible and useful. The company's first office was in a garage, in Menlo Park, California. Google's first employee was Craig Silverstein, now Google's director of technology. The basis of Google's search technology is called PageRank that assigns an "importance" value to each page on the web and gives it a rank to determine how useful it is. However, that is not why it is called PageRank. It is actually named after Google co-founder Larry Page.
4) Google receives about 20 million search queries each day from every part of the world, including Antarctica and Vatican. You can have the Google homepage set up in as many as 116 different languages –including Urdu, Latin, Cambodia, Tonga, and Yoruba. In fact, Google has the largest network of translators in the world.
5) In the earliest stage of Google, there was no submit button, rather the Enter key needed to be pressed.Google has banned computer-generated search requests, which can sop up substantial system resources and help unscrupulous marketers manipulate its search rankings.
6) The Google's free web mail service Gmail was used internally for nearly two years prior to launch to the public. The researchers found out six types of email users, and Gmail has been designed to accommodate these six. The free e-mail service recently changed its name for new UK users. Following a trademark dispute with a London-based Independent International Investment Research, the mail account has been renamed Google Mail.
7) It would take 5,707 years for a person to search Google's 3 billion pages. The Google software does it in 0.5 seconds. Google Groups comprises more than 845 million Usenet messages, which is the world's largest collection of messages or the equivalent of more than a terabyte of human conversation
8) The logos that appear on the Google homepage during noteworthy days and dates and important events are called Google Doodle. The company has also created an online museum where it has all the logos it has put on various occasions so far.Dennis Hwang, a Korean computer artist in the United States, is the guy behind these witty Doodles. Hwang has been drawing the face of Google for over two years.
9) You have heard of Google Earth, but not many know there is a site called Google Moon, which maps the Lunar surface. Google Moon is an extension of Google Maps and Google Earth that, courtesy of NASA imagery, enables you to surf the Moon's surface and check out the exact spots that the Apollo astronauts made their landings
10) Keyhole, the satellite imaging company that Google acquired in October 2004 was funded by CIA.Keyhole's technology runs Google's popular program Google Earth that allows users to quickly view stored satellite images from all around the world.

Folder Option Missing

Many of us sometimes find the folder option missing in the windows explorer.
Here is the solution—>

1.Open Run and Type "gpedit.msc"
2.Now goto User Configuration>Administrative templates>Windows Component>Windows Explorer
3.Click on windows Explorer you will find the thrid option on the right side of screen "Removes the Folder Option menu item from the tools menu"
4.just check it,if it is not configured then change it to enable by double clicking on it and after applying again set it to not configured.
5.I hope that you will find the option after restarting windows.

Multi Google Talk

Just follow the simple steps Below:

1.Right click on google talk shortcut,
2.click on properties
3.Go to shortcut tab on google talk properties window
4.on the target textbox,add in the /nomutex to the end of the line so that it looks like below(or you can simply copy and paste the below syntex and replace the original)
"c:\program files\google\google talk\googletalk.exe" /nomutex
5.click on ok

I didnt have to do anything after this and clicking on the shortcut multiple times just gave me different google talk window.

How Do You Speed Up Flex Builder?

Here is a article written by Brian Deitte(http://www.deitte.com/archives/2006/12/about_this_blog.htm) , explaining how to speed flex builder

Here are some of things we do:
1.Build every application in one project using multiple source paths (instead of using extra library projects)
2.Build parts of the applications as SWCs (instead of referencing their source paths)
3.Close extra projects
4.Use a system font instead of embedding fonts
5.Run "eclipse -clean" occasionally
6.Turn off "Copy non-embedded files to source folder"
7.Turn off "Build Automatically"

Things we haven't tried or just trying now and which may be helpful:
1.Build a lot of the application as SWCs or anything as an RSL
2.The Hellfire compiler (http://stopcoding.wordpress.com/2008/06/17/hellfire_compiler/)3.Use the Flex 4 SDK (or just the compiler portion) with Flex Builder
4.Merge some of the many Flex 4 compiler performance changes into a Flex 3 SDK, and using this in Flex Builder
