How to sense ESC key was pressed

visual studio .net general:

I have a long running loop that I want to exit/terminate from when the user
presses the ESC key in a Windows forms application (VS2005, VB language).

Can someone tell me how to achieve this?
Thanks

Check for message WM_KEYDOWN or WM_KEYUP and virtual-key code VK_ESCAPE

I'm a novice here, but when I look at a form's "Events" I see KeyDown,
KeyPress and KeyUp events. That sounds like what you are looking for and
should be easy to try. But, like I said, I am a novice.

Bob, thanks for your reply, but these events don't trigger until the loop
completes execution. If the ESC key is pressed, even after a couple of
seconds after execution is inside a loop then the ESC key is sensed only
after completion of the loop. I have also set the forms keypreview property
to true.
