文件自删除方法(ByBatFIle)

  除了通过cmd程序达到文件自删除以外，另一种方法就是通过Bat文件来完成文件自删除，代码如下：

#include<iostream>

#include<Windows.h>

using namespace std;

BOOL SuicideByBatFile();//文件自删除函数

int main()
{
SuicideByBatFile();
    return 0;
}

BOOL SuicideByBatFile()
{


CHAR  ProcessDirectory[MAX_PATH] = { 0 };
CHAR  ProcessFullPath[MAX_PATH] = { 0 };


CHAR BatFileFullPath[MAX_PATH] = { 0 };
GetModuleFileNameA(0, ProcessFullPath, sizeof(ProcessFullPath)); //获得当前进程完整路径
GetCurrentDirectoryA(MAX_PATH, ProcessDirectory);               // 获得文件的当前目录.

strcpy(BatFileFullPath, ProcessDirectory);
strcat(BatFileFullPath, "\\SuicideByBatFile.bat");

//创建Bat文件

HANDLE FileHandle = CreateFileA(BatFileFullPath, 
GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);


if (FileHandle == INVALID_HANDLE_VALUE)
{
return FALSE;
}

CHAR  v1[MAX_PATH] = { 0 };
CHAR  v2[MAX_PATH] = { 0 };

sprintf(v1, "del %s\n", ProcessFullPath);//编写指令
sprintf(v2, "del %%0\n");//编写指令

//将指令写入Bat文件

DWORD ReturnLength = 0;
WriteFile(FileHandle, v1, strlen(v1), &ReturnLength, NULL);
WriteFile(FileHandle, v2, strlen(v2), &ReturnLength, NULL);
CloseHandle(FileHandle);

WinExec(BatFileFullPath, SW_HIDE);

return TRUE;
}
