This example will toggle the selection state of the object under a given 2D point.

L_INT LVectorObject__IsObjectSelectedExample(HWND hWnd, LVectorBase *pVector, LPPOINT pPoint) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
 
   L_INT          nRet; 
   LVectorObject  VectorObject;    /* Object under point */ 
 
   // Get object under that point  
   nRet = pVector->HitTest(pPoint, &VectorObject); 
 
   //Is there an object under that point? If yes, select it 
   if (nRet == SUCCESS) 
   { 
      L_BOOL bSelected; 
 
      nRet = VectorObject.IsObjectSelected(&bSelected); 
      if(nRet != SUCCESS) 
         return nRet; 
 
      nRet = VectorObject.SelectObject(!bSelected); 
      if(nRet != SUCCESS)
