//
// Bill Berry			November 1996			Created
//                      March    1998           Update
//
// March update now includes Paul DiLascia's code from MSJ which
// allows the control to be used as a web link.
//
// Description:
//
//  Extended CStatic class. Allows easy customization of the following:
//
//      1. COLORREF CStaticEx::bkColor( COLORREF crColor )
//         - Sets back ground color of the control
//
//      2. COLORREF CStaticEx::textColor( COLORREF crColor )
//         - Sets text or foreground color of the control
//
//      3. COLORREF bkColor() const
//         - Returns back ground color of control
//
//      4. COLORREF textColor() const
//         - Returns text (or foreground) color of control
//
//      5. void onClickDoShellCommand( const CString& linkName )
//
//         (Note: the idea for this part of the control
//                came fom Paul DiLascia in the December issue
//                of MSJ )
//
//         - Use control as a link to open a link (this may
//           be an exe if you like...
//
//         COLORREF setLinkColorVisited( COLORREF crColor )
//         - Sets the visit color, returns previous setting
//
//         COLORREF setLinkColorUnvisited( COLORREF crColor )
//         - Sets the unvisited color, returns previous setting
//
//
