As suggested you could just do a non-modal dialog and then disable the
parent window getting a similar effect. You can use EnableWindow(false) to
disable a window and EnableWindow(true) to reenable it when the dialog is
complete. You could simulate the return code by just having a variable in
the dialog object that gets set.

Is it possible to create the window (hidden?) before calling DoModal(),
so that SetForegroundWindow() has something to operate on?

CDialog about(IDD_ABOUTBOX);
CWnd *pAbout = &about;
pAbout->SetForegroundWindow(); // exception

The reason is that I want to acquire/release a mutex around the
assignment of pAbout, but another thread using pAbout can't do
operations like SetForegroundWindow() until I call DoModal(). I can't
release the mutex after DoModal() because DoModal() doesn't return
until the window goes away, defeating the purpose of pAbout.
