How to sense ESC key was pressed

[Guest]

I have a long running loop in a Windows Form (VB2005 code). I want to be able
to terminate this loop when the user presses the ESC key. Can someone tell me
how this can be achieved?

Thanks,

It talks about it at the form level.

Mr.Arnold,
Thanks for your reply. but the ESC key press is sensed only after the loop
completes execution. the loop is in a procedure that is called from within a
click event of a button on a form.

Girish,

Have a look into the BackgroundWorker component of .net 2.0 in VS2005 to
help break out of your loop. By starting a new thread to process your
computation you are still able to manage and continue checking key events
etc from the parent thread.

Have a look here:

Those should help out.
