示例1: ReleaseChildren

/////////////////////////////////////////////////////////////////
// CBase::ReleaseChildren

HRESULT CBase::ReleaseChildren()

	while(hChildItem)
	{
		//NOTE: Before deleting this node of the tree, obtain the 
		//next sibling (if there is one...).  Since we can't do this after the node has been deleted!

		CBase* pCChild = (CBase*)pCObjTree->GetItemParam(hChildItem);
		
		if(pCChild)

			//If this child cannot be released, we still can continue on to the next child
			//(ie: release everything we can - not all or nothing...)

				pCChild->ReleaseObject();
			}
		}
		
		//Go to the next sibling...
		hChildItem = hNextSibling;
