BUG: Superclassed Scroll Bar's Parent Not Sent WM_CTLCOLOR Msg |
Q95391
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1
SYMPTOMS
Controls normally send WM_CTLCOLOR messages to their parents so applications can modify the control background color. However, under Windows 3.0 and 3.1, when a scroll bar is superclassed, its parent is not sent WM_CTLCOLOR messages.
RESOLUTION
Applications that want to receive the WM_CTLCOLOR message must subclass the scroll bar rather than superclassing its window class.
STATUS
Microsoft has confirmed this to be a bug in Windows versions 3.0 and 3.1.
