    Child with its own Registered Class

    I'm creating 2 classes with RegisterClassEx, one for the parent and one for a child.
    Each class has its own window procedure that handles its own messages.
    The child is receiving 95% of its messages, but not WM_MOUSEWHEEL and WM_KEYDOWN/UP.
    The parent gets them, of course, but I want the child to get them whenever the mouse is over the child.
    The first thing that came to mind was subclassing the child, but how when it has a class of its own?
    Or would that even be right since the child gets WM_LBUTTONDOWN/UP, WM_LBUTTONDBLCLK, and WM_MOUSEMOVE.
    What am I missing?
    Thanks.

    Try this in the parent's windowproc:
    Code:
    	case WM_SETFOCUS:
    		SetFocus(g_hwndChild);
    		return 0;
    You may also have to do an initial SetFocus call after creating and displaying the windows.

    BTW, this question actually belongs in the Windows forum.

    Thanks, I'm now doing SetFocus(hChild) in the child WM_LBUTTONDOWN and it works perfect.
    (sorry about the wrong forum)
