133    VBFireEvent

       	If a Visual Basic message box is displayed and a custom control calls
        VBFireEvent, the function returns a zero, meaning that the function
        was successful.  However, the event procedure in the Visual Basic code
        never gets completed.

142    VBGetDataSourceControl [3.0]

       The data type for the bIsRegister parameter should be BOOL FAR *,
       since the parameter is a pointer to a Boolean value.  If bIsRegistered
       is set to TRUE, the bound control has been properly initialized to
       the data control.
