SAMPLE: Changing Background and Text Color of Message Box

• Microsoft Windows Software Development Kit (SDK) for Windows, version 3.1

MSGCOLOR is a file in the Microsoft Software Library that demonstrates how to change the background and text color of a message box by subclassing the message box.

The MSGCOLOR sample implements the ColorMessageBox() function, which creates a message box whose background and text color can be changed. The function subclasses the message box and processes WM_CTLCOLOR to modify the colors. Subclassing the message box requires obtaining the window handle of the message box. The window handle is obtained using a WH_CBT hook. The hook is called when the message box is created, and provides access to the window handle.
