   keeping a fixed size window
  how can i keep a win32 window from being able to be resized.  i tried putting a switch for WM_SIZE in my WinProc and just having it return 0 but that closes the program...  any advice? 
  The window style WS_THICKFRAME is the one that adds a sizing border, im not quite sure if XORing that out will help you. Otherwise, you could process the WM_GETMINMAXINFO message. ;  WM_SIZE only occurs after   sizing happens.  Check out WM_SIZING.  It''s odd that returning 0 from WM_SIZE closed your program, though.
