You probably just forgot to include iomanip, but I can't be sure because you didn't include code for a complete program there.
This complete program works fine over here using VS 2003:

I can use the Control key in either the west or south-west positions without any trouble. Many Emacsers swear that the control key belongs in the west position and the west position only, and that anything else will ruin your pinky.

The only problem with using Triggers is that it adds to performance overhead of any insert/update/delete. For higher scalability and performance, you would like to keep the database transaction to a minimum.

You can try the [PHP PSD Reader][1], which should at least get you started.

$argv is an array containing all your commandline parameters... You need to parse that array and set $param yourself.
$tmp = $argv[1]; // $tmp="param=test"

$param = $tmp[1]; // $param = "test";

Using Adrian's solution, but instead of incrementing by 1, increment by 10 or even 100. Then insertions can be calculated at half of the difference of what you're inserting between without having to update everything below the insertion.

SysInternals may not help with Java class IO. Try getting a thread dump of the JVM (e.g., kill -3) while these logs are being written to. You should be able to catch a thread red handed with java.io packages near the top of the stack trace. |
Have you checked the logs in runtime/.metadata folder?,<br><br> Also make sure to validate all plugins in the runtime. Having them as a dependency doesn't necessarily mean they are added to the runtime. This is probably the biggest gotcha when launching an rcp app. |
Try the "libxslt-ruby" gem. It depends on the "libxmlr-ruby" bindings for libxml library, which you probably already have installed if you're developing on Linux. |

The finally block is always executed unless there is abnormal program termination, either resulting from a JVM crash or from a call to System.exit(0).

Depends on what you mean by crash.
You can do an infinite recursion to make it run out of stack space, but that'll crash "gracefully". You'll get an exception, but the JVM itself will be handling everything.
You can also use JNI to call native code. If you don't do it just right then you can make it crash hard.... |
If you change that infinite for loop to a recursive call to the same function, then you would get a stack overflow exception:
public static void main(String[] args) {

}
public void causeStackOverflow() {

The closest thing to a single "answer" is System.exit() which terminates the JVM immediately without proper cleanup. But apart from that, native code and resource exhaustion are the most likely answers. Alternatively you can go looking on Sun's bug tracker for bugs in your version of the JVM, some of which allow for re... |
Just a quick note, if you are using SQL Server, the examples that have:
While (Select Count(*) From #Temp) > 0

While EXISTS(SELECT * From #Temp)
The Count will have to touch every single row in the table, the `EXISTS` only needs to touch the first one.
