Hello everybody.

I'm developing a global hotkey plugin in C#, which works when outside MJ12 (Control in a Form) but has a small problem. Whenever I change the focus in MJ e.g to Playing Now, Audio or somewhere else the plugin is disposed :-( I need the context though, so that the plugin doesn't need to have focus to function.
 How is this accomplished ?

Thank you !

disposed may not be the right word.

Yeah you're right it isn't. The control just isn't visible anymore.

Well anyway evertime the control is opened it isn't just made visible. It recreated but that isn't a (big) problem anymore cuz I saved the hotkeys in a file.

 My problem now is the control doesn't recieve any WM_HOTKEY messages anymore. I hope this is not basic knowledge concerning controls but when it isn't visible no WH_*** messages are recieved in the WinProc :-( Is this normal behaviour ?

 If this is normal behaviour is there some kind of design pattern or algorithm that is used ?

Thanx

I was hoping you wouldn't say that :-( Not that it would be hard to do, but because the WM_HOTKEY message is there for a reason and a global hook would just be a workaround and not an actual solution. :-\

I'm also thinking about creating an invisible form, which would call the usercontrol's function...that'd be a very ugly solution. Aw man :-(

Thanks for hint Messiahs.

Edit: I just noticed I posted in the wrong forum. Mods please move the post if you feel like it.
Edit2: Does anybody know why the control doesn't receive any windows messages when invisible ?
