Keeping Focus of a Window

When I run an .exe file using ExecFile() from Blitz3D, the window with my game loses focus, even if the executable I'm running does not use any graphics functions.

Is there a way to regain focus?

if the blitzapp runs in windowed mode, then yes. If it was fullscreen then no since this will pause the blitzapp.

You can write a function in a decls file, I guess you need to use the PositionWindow Function, a function of the user32.dll AFAIK. I remember It tried this a long time ago, and Things like WindowSetfocus, BringWindowToTop, ShowWindow simply refused to work, so I used PositionWindow with the topmost parameter, this worked.

So you would need to run the other exe,then wait some seconds, then force the blitzapp to gain focus again.

EDIT - ouch - forget POsitionWindow, in fact the Syntax is:
SetWindowPos...

Hi JFK,

thanks for the tip... unfortunately I can't get it to go back into focus. I can move my window around no problem (so i know the command works), but even so it stays deactivated.

I've found this in the forums as well, as an "unstick" function:

SetWindowPos (GetActiveWindow (), HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE Or SWP_NOMOVE)

So obviously it works for others - no idea why it doesn't for me. Will keep trying, but if you have ideas, please let me know.

Thanks again!

OK, I also see your old post now, JFK:


Since my game is keyboard driven, I need full focus back. I've tried playing with the second parameter, but no luck.

Anyone have any suggestions?
