My comment:
Even better MessageBox customization can be achieved by creating an external library (ActiveX, DLL or FLL) and calling it from VFP application.
Download MsgBox FLL
The background color, the message text font & color, button fonts and captions, not to mention other customizable parameters, can be controlled by the calling application.
