I'm trying to make a boss key for my program, which is a global hot key used for activeing or hiding all windows of my program, whether the program is active.
I searched about this kind of hot key, it needs WIN32 API RegisterHotKey() .
But the problem is that my program may have more than one windows at one time, and how can I make a function to handle these windows? I cannot write RegisterHotKey() to each window.
Anyway,thanks...
