大家一起来学习一下，代码如下：
//这里是DLL入口
#import "C:\WINDOWS\system32\msxml.dll"
#import "C:\WINDOWS\system32\msxml2.dll"
using namespace MSXML2;
HRESULT ComInit();
#include "stdio.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
ComInit(); //青年人网站提示: 调用下面初始化COM的函数
IXMLHTTPRequestPtr xmlrequest; //定义变量
xmlrequest.CreateInstance("Msxml2.XMLHTTP");
xmlrequest->open(_bstr_t("GET"),_bstr_t("http://www.baidu.com/s/index.asp?wd=vc+Com&tn=site888_1_pg&cl=3&ie=utf-8"),_variant_t("false"));
xmlrequest->send();
BSTR bstrbody;
xmlrequest->get_responseText(&bstrbody);
_bstr_t bstrtbody(bstrbody);
MessageBox(0, (LPCTSTR)bstrtbody, "OK", MB_OK);
return 0;
}
//这里是初始化COM
HRESULT ComInit()
{
HRESULT hr = S_OK;
if FAILED(CoInitialize(NULL))
{
CoUninitialize();
hr = E_UNEXPECTED;
}
return hr;
}
