You made me second guess myself, so tested it. With the following code no
window was display until I dismissed the about dialog.

void CLoginTestView::OnInitialUpdate()
{
   CView::OnInitialUpdate();

   UpdateWindow();
   CAboutDlg Dlg;
   Dlg.DoModal();
}

Not true. UpdateWindow will cause the window to draw if it is still
hidden, as is usually
the case during OnInitialUpdate. I've used this technique numerous times
and never seen a
failure.

The UpdateWindow call is irrelavent. If the window is already up then
everything is ok, if the window is not up yet, as the case would be in
OnInitialUpdate then calling UpdateWindow before you call DoModal will not
do anything at all.

Why painting code? That is a really poor place for something like that.

As I say, I don't like it either. But it occurred to me that calling it
in the painting code ensures that the dialogue comes up after the Window
is painted :-)

Otherwise PostMessage is a very good solution.

I use it a lot for "do this in a moment" things.

Another (better?) solution, now you mention it, is in the response to
the
message, do an UpdateWindow() immediately before launching the dialogue.
