I am writing a windows forms application in Visual Basic, and I would like to know how to execute some code when any key is pressed in any window. I have tried onkeypressed, but that only works in the form, and I want to have it system-wide. Can anyone help? I'm pretty new to VB, but I know the basics...

Thanks, Matt

  • My program is not in the background (although it might be later, but not now) and I want to do something when ANY key is pressed. Not just Mod + O – UltraLuminous Oct 29 '16 at 14:53
  • It works in the foreground too. "Background" refers to any time neither of your windows are focused (and you did say system-wide, so...). So you want to capture _any_ set of keys, and not just predefined ones? Somewhat like a keylogger? – Visual Vincent Oct 29 '16 at 14:56
  • Somewhat I guess. But it wont be a keylogger, don't worry :D – UltraLuminous Oct 29 '16 at 14:57
  • Oh, well the question I linked to is mainly to be used for hotkeys (sorry for not understanding your request), then what you need is a [system-wide keyboard hook](http://stackoverflow.com/a/15038869/3740093). – Visual Vincent Oct 29 '16 at 14:59
  • Thanks so much, that should do it! Add it as an answer,.and I will mark it as solved. – UltraLuminous Oct 29 '16 at 15:01

  • Okay... I'll try that. – UltraLuminous Oct 29 '16 at 15:03
