Example

This example displays the total number of objects in each group in a vector.

class LMyVectorGroup1: public LVectorGroup
{
public:
   L_INT          m_nObjectCount ;
public:
   LMyVectorGroup1() {m_nObjectCount=0;};
   virtual ~LMyVectorGroup1(){};
   virtual L_INT  EnumObjectsCallBack( pVECTORHANDLE pVector, pVECTOROBJECT pObject);
};
L_INT LMyVectorGroup1::EnumObjectsCallBack( pVECTORHANDLE pVector, pVECTOROBJECT pObject)
{
   UNREFERENCED_PARAMETER(pVector);
   UNREFERENCED_PARAMETER(pObject);
   m_nObjectCount++;
   return SUCCESS;
}
