CWnd::PostMessage doesn't try to validate the object against handle map. It
just fetches m_hWnd from it. In this sense it's safe to call from another
thread (assuming CWnd pointer itself is still valid).

You shouldnt call PostMessage from the worker thread. Use ::PostMessage
instead along with the handle of the dialog. The mapping between CWnd and
HWnd is not valid across threads.

I have a modal dialog that simply displays the status of loading a

thread is created to do the actual work. When the background thread
is done, it posts a user message back to the dialog. That user
message handler calls DestoyWindow() and the app GPF's!

How do I close this darn dialog box? I have been away from MFC too
long;)

Do you ever get so fed up with something that you post a quetion
before exausting all possiblities? I found the solution:

PostMessage(WM_CLOSE, 0, 0);

And it is early still!
