Hi guys, when I initialize my fullscreen app I want to show a MessageBox() if it fails but it's not showing.
hWnd=CreateWindow(...);
if(!initSomeStuff())
goto cleanup;
if(!initD3D())
goto cleanup;
if(!initOtherStuff())
goto cleanup;
// message pump here
cleanup:
MessageBox(hWnd,"error","error",MB_OK);
I tried GetDesktopWindow() and NULL for the first param to MessageBox(). If initSomeStuff() fails it shows fine, but not for the following two tests (because D3D is setup in fullscreen at that point.)
Is the MessageBox invisible?
Probably you have sent PostQuitMessage and Windows is not processing your windows after that.
The other scenario.
Your MessageBox is hidden behind fullscreen window.
In this case you would hide this fullscreen window (I am sending WM_CLOSE to that object).
