Hi Xiaomei, Sorry for the lack of my responses. It seems a known issue of a RichEdit control (*1), which automatically changes its keyboard layout with the current selection. When I create a simple MFC application which just shows a dialog including a RICHEDIT20 control, it also changes its keyboard layout automatically on my Vista PC.
(*1) http://social.msdn.microsoft.com/forums/en-US/vcgeneral/thread/b640e764-0c3c-43fc-a670-4c5e73167ce4/ I'm also trying possible solutions for this issue now.
