Window Focus

Hey guys, what's the best way to check and see if your Blitz app has focus? I did a search and people mentioned something like user32.

What is that and where can I find it? If that's not the best way to go, what is?

Thanks! :)

user32 is a dll, create a file called "user32.decls" in your "userlibs" folder from this:

Then you need the MSDN online win32 help, or get a copy of the old win32.hlp, here for example:

Here is a GetFocus example.

;GetFocus example

Graphics 640,480,0,2

hwnd=Api_GetFocus()
;similar commands
hwnd2=Api_GetForegroundWindow()
hwnd3=Api_GetActiveWindow()

While Not KeyHit(1)
 Cls

 test=Api_GetFocus()
 If hwnd<>test Then End ;if focus not on this app then quit

 Text 0,0,"hwnd="+hwnd+" hwnd2="+hwnd2+" hwnd3="+hwnd3
