My comment:
Setting the font size to a larger value can cut part of the message off. This happens because of the MessageBox function calculating the size for the message rectangle based on the default font.

By adding some extra CHR(13) characters (the carriage returns) the height of the message can be artificially increased. This solves the problem though only partially.

Ideally the size of the message rectangle must be re-calculated by the calling application, which then also should resize the message window and resize and reposition all other windows accordingly.

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.

* * *
The MessageBox dialog consists of several windows.



The Dialog Window is the parent window, and all others are its children: the message window, the icon window and the buttons.

The Tool window (its Control ID 0x0000CAFE always makes me feel good) is an addition to the MessageBox child windows that came with the Vista.
