Hello Sc0rch

If you use GetWindowIdFromCaption() (SysInfo package) instead of FindWindow, this code will serve you for Linux too.

Sorry for the propaganda Smile

Best regards
Koldo



Hmm, function not work, what I'm doing wrong?

if (GetWindowIdFromCaption(name, true) >= 0)
	{
		if (message)
			Exclamation("Another instance of application already exists!");
		return false;
	}



Hello Sc0rch

GetWindowIdFromCaption(name, true) tries to find a window with title == name.

GetWindowIdFromCaption(name, false) will get the window handle of the window with a title that just contains name.

If it does not work could you give me more details ?.

Best regards
Koldo

Best regards
Iñaki
