ALT-TAB

The message is WM_ACTIVATE:

case WM_ACTIVATE: { if (LOWORD(wParam) == WA_INACTIVE)) // Focus was lost else if ((LOWORD(wParam) == WA_ACTIVE) || (LOWORD(wParam) == WA_CLICKACTIVE)) // Focus was gained } break;

Pretty sure that''s how it goes.



The road to success is always under construction

Are you sure? I thought:

case WM_SIZE: { if (wParam == SIZE_MINIMIZED) //We were minimized else if (wParam == SIZE_MAXIMIZED) || (wParam == SIZE_RESTORED) //We are back up again }

This is what I've seen. But If I remember correctly there are many ways of doing it, but the biggest mistake everyone makes is that at the beggining of your program/game when it's just first loading, they load there graphics, but they also get the SIZE_RESTORED message when it run, so they re-load and restore all the surfaces... so you have to do some smart thinking so that you don't do the same thing twice at the beggining of your game.

Another thing is set the display mode back while they are away from your game then set up again for your game. Many people get really anoyed when it messes there resolution and stuff..

Good luck!

I had a great trouble about it. When you recieve WM_ACTIVATE check

BOOL bMinimized = HIWORD(wParam);

bMinimized tells if the window is minimized right now (before th e Windows will try to change it''s state). AND ONLY RELEASE YOUR STUFF IF bMinimized == false. AND RELOAD EVERYTHING ONLY IF bMinimized == true.

Do not forget about it.
