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
I think you should check if the window you have in the first return of
AfxGetMainWnd() is the same window as in the second time. If you have a
variable of your CWinApp derived class, (like CSampleApp theApp), try
theApp.GetMainWnd().
Hello AnRil,
Thanks for the suggestion, but that didn't solve the problem either.
BTW, my application is not an automation client/server.

What about AfxGetApp()->GetMainWnd()? Or
AfxGetApp()->GetMainWnd()->GetForegroundWindow(). Does any of this help?
In my program it did help.
