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
