Com调用程序运行成功，但退出后Windows弹框报一个未知错误，为什么?

Question

下面这个程序是调用msxml写了一个xml文件，这个文件就一行
<person>somebody</person> 
#include "stdafx.h"
#include <stdio.h>
#import <msxml.dll>
int _tmain(int argc, _TCHAR* argv[]){
CoInitialize(0);//ATL库才能支持CComPtr. CComPtr<MSXML::IXMLDOMDocument> spDoc;
IXMLDOMDocumentPtr pDoc;
pDoc.CreateInstance(__uuidof(DOMDocument));
IXMLDOMElementPtr pNode;
pDoc->createElement((_bstr_t)"person",&pNode);
pNode->put_text((_bstr_t)"somebody");
pDoc->appendChild(pNode,0);
pDoc->save((_variant_t)(_bstr_t)"d:\\my.xml");
printf("ok\n");
CoUninitialize();
return 0;
}

Answer 1

CoUninitialize();前加上pDoc->Release()

Answer 2

不行，我在CoUninitialize()前面加上pDoc->Release()或者pDoc.Release();都还是抱错误，提示是否把这个错误发送给微软。我对程序作了小的调整。还是不行。#include "stdafx.h"
#include <stdio.h>
#import <msxml.dll> rename_namespace("msxml")
int _tmain(int argc, _TCHAR* argv[]){
CoInitialize(0);//ATL库才能支持CComPtr. CComPtr<MSXML::IXMLDOMDocument> spDoc;
msxml::IXMLDOMDocumentPtr pDoc;
pDoc.CreateInstance(__uuidof(DOMDocument));
pDoc->put_async(VARIANT_FALSE);
pDoc->put_validateOnParse(VARIANT_FALSE);
pDoc->put_resolveExternals(VARIANT_FALSE);
msxml::IXMLDOMElementPtr pNode=pDoc->createElement((_bstr_t)"person");
pNode->put_text((_bstr_t)"somebody");
pDoc->appendChild(pNode);
pDoc->save((_variant_t)(_bstr_t)"d:\\my.xml");
pDoc->Release();
CoUninitialize();
return 0;
}

Answer 3

把pDoc->put_async put_validateOnParse put_resolveExternals去掉。

Answer 4

//改成
IXMLDOMDocumentPtr pDoc;
pDoc.CreateInstance(__uuidof(DOMDocument));
m_pDoc->loadXML((_bstr_t)(_T("<person></person>")))
m_pDoc->GetlastChild()->put_text((_bstr_t)"somebody");
pDoc->save((_variant_t)(_bstr_t)"d:\\my.xml");
printf("ok\n");
CoUninitialize();

Answer 5

pNode.Release();
pDoc.Release();

Answer 6

我要的是新建一个文件，而不是改写一个已经存在的Node.
谢谢
