Description & Usage

The MsgBoxCallback callback function processes help events generated by a message box. It receives information about what context-sensitive help information to display to the user. Like all callback functions, this function does not need to be named MsgBoxCallback inside your program. MsgBoxCallback is merely the name given to it in discussions about the Windows API.

Return Value

MsgBoxCallback does not return a value.

Visual Basic-Specific Issues

Like all callback functions, MsgBoxCallback must be declared Public and be defined in a module.

Parameters
