      DWORD dwCount = GetRegionData( hrgn, 0, NULL );

dwCount is always zero so the if( dwCount > 0 ) block is never
executed. BTW, I tried calling OldWindowProc before and after
checking for WM_NCPAINT and I tried not calling it at (in
conjunction with setting Message.Result = 0). All attempts had
the same result with dwCount being zero.

    OldWindowProc( Message );
    if( Message.Msg == WM_NCPAINT )
      {
          char *Buffer = NULL;
          RGNDATA *pRgnData;
          HRGN hrgn = (HRGN) Message.WParam;
          DWORD dwCount = GetRegionData( hrgn, 0, NULL );

          if( dwCount > 0 )
            {
                Label1->Caption = "Made it to here";
