BUG: Superclassed Scroll Bar's Parent Not Sent WM_CTLCOLOR Msg

Last reviewed: January 5, 1995
Article ID: Q95391

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) for Windows versions 3.1 and 3.0

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. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
