Example

This example will add a new layer to a vector handle.

L_INT LVectorLayer__GetLayerDescExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
 
   L_INT             nRet; 
   LVectorLayer      VectorLayer; 
   VECTORLAYERDESC   LayerDesc; 
 
   nRet = VectorLayer.GetLayerDesc(&LayerDesc); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   lstrcpy(LayerDesc.szName, TEXT("Terry's New Layer")); 
 
   VectorLayer.SetLayerDesc(&LayerDesc); 
 
   nRet = pVector->AddLayer(&VectorLayer, VECTOR_FLAGS_RENAME_DUPLICATES); 
   if(nRet != SUCCESS) 
   { 
      MessageBox( NULL, TEXT("Could not add layer!"), TEXT(""), MB_OK ); 
 
      return nRet; 
   }
