keyboard event callback

[Pnt]

I want to capture a key-pressing from keyboard, at a vi that it's window does not has focus on it. So i can not use the simple event "this vi >> key down".

I know how to do it by polling. But i can not find a way to do it with a callback event.

There are a few posts related, but i can not find the answer.

You can't catch the event.  Becasuse there isn't one for an non-active window.  Only the active window get the event.

If you're a good C programmer, you can create a hook dll, set it to catch keyboard event from any window.

You may have problems with running this setup w/ some antivirus softwares installed.  It could identify your code as a keylogger application unless you use ctrl, alt, shift combinations.

Thank you.

That clears things up.

I will use polling. It is not so bad at all..

Would you please tell me how it might be done with polling... I am having similar issues, but I don't know how to do this with any method!
