Example

This example will toggle the use of pen and brush color red and blue for markers. 

L_INT LVectorBase__SetMarkerExample(HWND hWnd, LVectorBase *pVector)
{
   UNREFERENCED_PARAMETER(hWnd);
   L_INT          nRet;
   VECTORMARKER   Marker; 
   // Get marker settings 
   nRet = pVector->GetMarker(&Marker );
   if(nRet != SUCCESS)
      return nRet;
   // Toggle pen and brush color between red and blue 
   if( Marker.Pen.NewPen.LogPen.lopnColor == RGB( 0xFF, 0x00, 0x00 ) )
   {
      Marker.Pen.NewPen.LogPen.lopnColor = RGB( 0x00, 0x00, 0xFF );
      Marker.Brush.BrushType.StandardBrush.LogBrush.lbColor = RGB( 0x00, 0x00, 0xFF );
   }
   else

      Marker.Pen.NewPen.LogPen.lopnColor = RGB( 0xFF, 0x00, 0x00 );
      Marker.Brush.BrushType.StandardBrush.LogBrush.lbColor = RGB( 0xFF, 0x00, 0x00 );
   }
   Marker.dwFlags = Marker.dwFlags | VECTOR_MARKER_PEN_COLOR | VECTOR_MARKER_BRUSH_COLOR;
   // Set new marker 
   nRet = pVector->SetMarker (&Marker );
