directdraw is evil
category: general [glöplog]
So I've been messing with ddraw and stuff lately.. everything works fine, except whenever the user presses alt-tab, does something else and then tries to get back onto the demo then everything explodes. I've added handlers for WM_ACTIVATE and stuff.. it's a crash, not just an infinate loop or anything, because even when I do ctrl-alt-del it reports it as "not responding" and has to eat it or something to make it close. Normally it'll just get WM_QUIT and then close.. what's up with it? I'm sure it's something utterly obvious, heh...

Code:
if(mySurface->IsLost()) {
mySurface->Restore(); // add some checking here, try
// again later if it fails
}
mySurface->Lock(.....
