WM_CTLCOLOR

[gucy]

can anybody tell me something different between WM_CTLCOLOR and =WM_CTLCOLOR in mfc? gucy

The WM_CTLCOLOR message is used in 16-bit versions of Windows to change the color scheme of list boxes, the list boxes of combo boxes, button controls, edit controls, static controls, message boxes, and dialog boxes. If an application processes this message, it returns a handle to a brush. The system uses the brush to paint the background of the control =WM_CTLCOLOR In classwizard WM_CTLCOLOR will appear as "=WM_CTLCOLOR"

This has to do with subclassing of controls. I really can't elaborate that much on the topic because I have used it only once and I hardly remember it, but go to MSDN and search for subclassing. // Afterall, I realized that even my comment lines have bugs

WM_CTLCOLOR is the Windows message sent to the parent of a control. MFC allows the control itself to handle some messages that are actually sent to its parent. This is called message reflection, and WM_CTLCOLOR is one of these messages. If you handle WM_CTLCOLOR in a particular window (eg. myWindow), then you handle a message sent from one of myWindow's children. If you handle =WM_CTLCOLOR, you handle a message that was sent from myWindow to its parent.
