Example

This example will delete all clones of the named group from pVector.

L_INT LVectorBase__GetGroupByNameExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
   LVectorGroup   VectorGroup; 
   L_INT          nRet; 
   L_TCHAR*       pszName = TEXT("TerryGroup1"); 
   // Get the group with the given name 
   nRet = pVector->GetGroupByName(pszName, &VectorGroup ); 
   if( nRet == SUCCESS ) 
   { 
      // Delete its clones 
      nRet = VectorGroup.DeleteGroupClones(); 
      if(nRet != SUCCESS) 
         return nRet; 
   } 
   else 
      return nRet; 
   return SUCCESS;
