You could try making the window "topmost". Or put the lengthy operation
into a worker thread or use code like:

//
// Release main thread for background processing
//
void GiveTime()
{
// Idle until the screen redraws itself, et. al.
MSG msg;
while (::PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE ) ) {
  if (!AfxGetThread()->PumpMessage( )) {
   ::PostQuitMessage(0);
   break;
  }
}
// let MFC do its idle processing
LONG lIdle = 0;
while (AfxGetApp()->OnIdle(lIdle++ ))
  ;
}

That would allow your main GUI to redraw. I wouldn't call this very often
(perhaps every few seconds or several hundred iterations through a loop).

Hello,

I have an application that creates modeless dialog for application
status messages. It has no title bar. I run lengthy operation in
code and if user switches windows, modeless dialog disappears in
background. I try to bring it back up using Alt+Tab but it never
does. If other windows are minimized it reappears. I tried
SetForegroundWindow, SetFocus etc. functions but not much luck. Need
some help.

Thanks
