WM_EXITSIZEMOVE is received immediately after trying to resize the window in VC++ application

Hi,
I have an application on XP.  After application started,  the window can be resized by dragging right border of window.  However,  after CDialogBar is created,  the window can not be resized.

I traced the message via Spy++,  it seems a message "WM_EXITSIZEMOVE" is sent to application right after I started moving right border of window.

The strange thing is, when I remotely login on the Desktop, and start the application, create CDialogBar, the window resizing works fine.  There must be something missed which caused it. But I have no ideas on this.

Please help!

Hi, Alb66,

I've figured it out. The problem was due to a call to PostMessage(WM_LBUTTONUP).  When I starting Resizing the window, immediately received this message and stopped Resizing.  I got it fixed.

Thanks so much!

Sorry, I didn't mean to request 250 points. It was an accident!  Please ignore it.
