   Sending WM_SIZE just to update
  Hello!I have a button that blends a small help-list of commands out. Unfortunately this happens only when I resize the window, because all control placement happens in the "case WM_SIZE:" section. I've tried to just call SetWindowPos or MoveWindow for that window. I also tried SendMessage with a WM_SIZE, but all of them didn't trigger the WM_SIZE message I want.   
  Erm... any particular reason why you can't move the control sizing logic from the WM_SIZE handler? Perhaps you could post the relevant code for examination?   ;  Aww. Sorry, it was a bit late last night. ;) I did it just like that after I slept about it...
