怎么实现程序自我删除

Question

自己做了一个名为  abc.exe 的小程序， 其中我在代码里边添加了 System("del  abc.exe");  这个代码，最后删除不成功，提示说程序运行中无法删除，我想问一下程序是怎么实现自我删除的？

你好，

根据你的问题，下面这个代码我已经调试过了，可以正常运行。供你参考。

程序自我删除一是可以利用windows的command program的删除文件操作；其次可以启动新的进程来执行这个删除操作。

更多解释内容，可以参考以下这篇文章：

http://hi.baidu.com/whmtorrent/item/083e3d4a8348beeaa5c066b7

#include "stdafx.h"
#include <Windows.h>
#include <strsafe.h>

#define SELF_REMOVE_STRING  TEXT("cmd.exe /C ping 1.1.1.1 -n 1 -w 3000 > Nul & Del \"%s\"")

void DelMe()
{
    TCHAR szModuleName[MAX_PATH];
    TCHAR szCmd[2 * MAX_PATH];
    STARTUPINFO si = {0};
    PROCESS_INFORMATION pi = {0};

    GetModuleFileName(NULL, szModuleName, MAX_PATH);

    StringCbPrintf(szCmd, 2 * MAX_PATH, SELF_REMOVE_STRING, szModuleName);

    CreateProcess(NULL, szCmd, NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &si, &pi);

    CloseHandle(pi.hThread);
    CloseHandle(pi.hProcess);
}

void main()
{
    /* Do what you need */

    /* Call this function at the very end of your program to delete itself */
    DelMe();
}

Best Regards!
