SAMPLE: MsgColor.exe Changes Msg. Box Background & Text Color

ID: Q99808

The information in this article applies to:

SUMMARY

MsgColor.exe is a sample file that demonstrates how to change the background and text color of a message box by subclassing the message box.

MsgColor.exe 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.
