Has anybody ever gotten Alt+TAB working ?
Author
I have tried absolutely everything and I just can''t get it working. It just seems impossible...
This is the code I use at the moment:
case WM_SETFOCUS:
SetCursor(0);
ACTIVE=TRUE;
if(FOCUSLOST){
Beacon(123);
while(g_pDDSPrimary->Flip(0, DDFLIP_WAIT)==DDERR_SURFACELOST){
g_pDDSPrimary->Restore();
g_pDDSBack->Restore();
Beacon(1234);
}
RestoreAll();
ReacquireInput();
if(GameStatus==PLAY&&PlayStatus==PLAYING){
if(PAUSE)
Pause();
BLIT=TRUE;
Blitted=0;
}
FOCUSLOST=FALSE;
}
return 0;
case WM_KILLFOCUS:
ACTIVE=FALSE;
FOCUSLOST=TRUE;
ACTIVE=FALSE;
for(int Y=0;YFlip(0, DDFLIP_WAIT)==DDERR_SURFACELOST) loop when I reactivate the app. Am I supposed to use WM_KILLFOCUS
and WM_SETFOCUS or something else? Is there anythinig else I need to think of?
Please help me, I''m really desperate!

Have you read the section on this in the DX8 SDK docs? Use IDirect3DDevice8::TestCooperativeLevel() to check if the device is ready to be reset (ie your app has regained focus). If it is then you need to reset it with IDirect3DDevice8::Reset().
Also make sure the D3DPRESENT_PARAMETERS you are supplying to Reset() still contains correct values.
Other than that you need to restore IBs, VBs and textures that were in D3DPOOL_DEFAULT memory.
I personally don''t run my main loop when the device is lost, I just call a function that checks is a reset is possible, and then attempts to reset if it is.
Good luck

I have now looked a little on testcooperativelevel though I''m not sure how to use it. Should I loop until it returns DD_OK in the WM_SETFOCUS case, before restoring surfaces? I''ll give it a try... In the meantime, does anybody have any example or an article on how to get this working?
Btw, I am not using d3d.
I have been trying for several days now so I really appreciate your help.

Try keep the program in a loop until the cooperative level is restored, like this;
I found that just waiting for the initial message was not enough, and I could receive 4 or 5 messages before the cooperation level was restored.

HRESULT hr = lpDD->TestCooperativeLevel();if (hr == DDERR_NOEXCLUSIVEMODE){ MSG msg; WaitMessage(); // the app will now pause do // wait inside this message pump until //the coop level is restored { int bGotMsg = PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ); if (bGotMsg) { DispatchMessage(&msg); hr = lpDD->TestCooperativeLevel(); } }while (hr != DD_OK);} I found that just waiting for the initial message was not enough, and I could receive 4 or 5 messages before the cooperation level was restored.

>>Sorry about that Didn''t read your code carefully enough.
You tried to help me at least =). I wouldn''t have read all that code either!
Just thought I''d tell you all that I finally got it working!!!
3dModelMan, thank you for the tip and the code and I want to thank all others who tried to help =) I never thought I''d get it working!
