what tag is it??

After "See more". Use "Improve answer", see text input "Tags", add ", Forms". I would like you to know it as next time you need to tag it, if you want experts to recognize your question by tags and eventually answer.

Is it a problem at all or not? Simply put a break point in this method and you will see what happens if you press a hot key, use other message parameters accordingly. The message structure is documented here: http://msdn.microsoft.com/en-us/library/ms646279(v=vs.85).aspx[^].

Any questions?

I don't understand where the problem is. Put a breakpoint and try to hit a hotkey. Does you code stop there? You have everything to do it.

thanks. the code i asked have no problem. But when i hold my HotKey(let say 'F8'), it will not stop until i release F8.
So, i would like to find a solution that can prevent problem when i hold down F8.
hope you can understand :(

What not stop. You probably get events from auto-repeating keyboard event. You can devise different scenarios checking that the event is repeating and using only first occasion. One of the simplest -- process releasing key, not pressing -- it will come only once.
Any questions?
