I got a programm, that works with xml files. And it uses MSXML.dll. But i found i greate memory leak, and i can't understand - what am i doing wrong???
Here is the code:
#pragma once
#include <vector>
#import <msxml.dll> named_guids
using namespace MSXML;
using namespace std;
/*struct Nomenklatura
{
	CString FullPath;
	CString Code;
	CString Name;
	CString Price;
};*/

class CNakladImporter

	vector <CString> m_vHead;
	vector <CString> m_vHeadForAgents;
	
	CFile m_File;
	CString m_PathToNomen;
	CString m_PathToAgents;
	CString m_PathToNaklad;
	MSXML::IXMLDOMDocumentPtr m_plDomDocument;
	MSXML::IXMLDOMElementPtr m_plDocRoot;
	void GetChild(MSXML::IXMLDOMNodePtr pParent,CString FullPath);
	void GetChildForAgents(MSXML::IXMLDOMNodePtr pParent);

	int CreateHead(MSXML::IXMLDOMNodePtr pParent);

Please help, anybody...
Maybe problem in smart pointers???
If i don't call CreateInstance of smart pointer object, do i have to call Release??? Or can i send it in function parameter Somenting(SMartPtr pPtr)???
