Have you tried calling both BringWindowToTop() and SetForegroundWindow().
Also, perhaps instead of disabling your main window you could just iconize
it or hide it using ShowWindow(). Would that give you the same
functionaility you need?

Hello,

I have trouble with AfxGetMainWnd()->EnableWindow() at least on Windows
XP. Not tested this . My main application needs to run another GUI program
and while this program run should not be accessible for user input. In
order to do this I call AfxGetMainWnd()->EnableWindow(FALSE); Start the
GUI program Then use a bit of code to wait for the GUI to finish. See
snippet below:
HANDLE aHandles[2];
aHandles[0] = GetCurrentProcess();
aHandles[1] = hGUI;
do
{
    DWORD dwResult = ::MsgWaitForMultipleObjects(2, aHandles,
       FALSE, INFINITE, QS_ALLEVENTS);
    if ( !prcGUI.IsRunning() )
break;
} while ( AfxGetThread()->PumpMessage() );

However, when the GUI program stops my main application won't get the
focus automatically again after I call
AfxGetMainWnd()->EnableWindow(TRUE); The application behaves as being
minimized and I have to explicitly click on the program icon in the
desktop bar to bring it back up.
I tried different combinations of SetActiveWindow(),
SetForegroundWindow(), BringWindowToTop() and SetFocus() but nothing
happens.
If I don't use EnableWindow() this problem does not occur.
So in short how to force my application back to the foreground?

Any help appreciated,
Theo
