    FILE: Windows Parental Controls utility function header file

    PURPOSE: Common functions for WMI support

    FUNCTIONS:

        WinMain() - calls initialization function, processes message loop
        DemoInit() - initializes window data and registers window
        DemoWndProc() - processes messages
        About() - processes messages for "About" dialog box

    COMMENTS:
        This code is a modified version of the CURSOR.C program.  Instead of
        using inline code for drawing the shape, the routines from the Select
        library are called.
