求vc写的直接从一个网站上下载exe程序得源代码!
首先引入头文件#include"afxinet.h"。使用函数BOOL GetFromWeb(LPSTR pURL,源码LPSTR SaveAsFilePath)进行操作。
其中，源码易语言源码打开失败修复参数pURL为URL路径，源码SaveAsFilePath为保存路径。源码驱动源码大全初始化CInternetSession session;作为会话期对象，源码hearbeat 源码安装CHttpConnection *pServer=NULL;指向服务器地址(URL)，源码CHttpFile *pHttpFile=NULL;为HTTP文件指针。源码
定义CString strServerName;为服务器名，源码CString strObject;为查询对象名(会话。源码if(pHttpFile!=NULL) delete pHttpFile; if(pServer!=NULL) delete pServer; session.Close(); return TRUE;
至此，源码从指定网站下载exe程序的源码源代码的过程完成。通过调用该函数并传入URL和保存路径即可实现。源码android助手源码
