    umm doesnt any1 out there know? err its a simple question really, ill rephrase it:

    does a static control within a groupbox receive the WM_STLCOLORSTATIC Message?

    an even simpler way of putting it:

    how do i make my static controls static if its in a groupbox?

    someone please help

    thanx

    Please don't bump your threads.

    >> i thought maybe i should subclass the actuall groupbox and handle each message myself, but im not sure<<

    Did you try this in the 24 hours since you posted your question?

    The answer to your question is wrapped up inside your question; a swift review of WM_CTLCOLORSTATIC should resolve any doubts.

    >>err its a simple question really<<

    Indeed it is - as is the answer.

    AFSIK static controls don't send msg's to their parent, so can't be subclassed in the way you want.

    >>and it works fine if i set the controls parent to the hWnd of the window, but if the statics control's parent was a groupbox,<<

    All child windows msg's are routed to the callback of their parent. If you set the parent to a static then the static would have to ahve its own callback. This can be set with GetWindowLong() or GetWindowLongPtr() and then set with SetWindowLong() or SetWindowLongPtr()

    Code:
    lpfnOriginalWndProc = (WNDPROC)GetWindowLong(hWndControl , GWL_WNDPROC);
    SetWindowLong(hWndControl , GWL_WNDPROC, (LONG) NewWndProc);
