That button sends
SC_CLOSE Closes the window. This command sends a WM_CLOSE
message to the window. The window carries out any steps needed to
clean up and destroy itself.
That suggests that if you send yourself a WM_CLOSE, that it will have
the same effect as the X.
case WM_COMMAND: // message: command application menu
switch(wParam)
{
case CM_EXIT:
PostMessage(hWnd,WM_CLOSE, NULL,0);
return 0;

PostQuitMessage is the _last_ thing you do.
It stops the message pump and exits.
Clean up everything _before_ posting that message.

If sending yourself a WM_CLOSE doesn't do it, then you could try
sending an SC_CLOSE (See WM_SYSCOMMAND)
Something like
DefWindowProc(hWnd,WM_SYSCOMMAND,SC_CLOSE, 0);
