程序自删除VC++代码

void ExitAndDeleteSelf()

{

#define BAT_FILE_NAME "看你妹.bat"

char szExePath[512] = {0};

GetModuleFileName(NULL, szExePath, 512);

HANDLE hFile = CreateFile(BAT_FILE_NAME, FILE_GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

if (hFile == INVALID_HANDLE_VALUE)

return ;

DWORD dwTmp=0;

char szBuf[2012] = {0};

wsprintf(szBuf, ":nimei\r\ndel \"%s\"\r\nif exist \"%s\" goto nimei\r\ndel %%0", szExePath,szExePath);

WriteFile(hFile, szBuf, lstrlen(szBuf), &dwTmp, NULL);

CloseHandle(hFile);

ShellExecute(0, NULL, BAT_FILE_NAME, NULL , NULL, SW_HIDE);

ExitProcess(0); //vc6 这地方可能会崩溃  换成exit(0)； 可能就好了。

}

另一种方式：

#include "shlobj.h"

void DeleteSelf()

{  

SHELLEXECUTEINFOsei = {0};

TCHARszModule [MAX_PATH] = {0};

TCHARszComspec[MAX_PATH] = {0};

TCHARszParams [MAX_PATH] = {0};

if((GetModuleFileName(0, szModule, MAX_PATH) != 0) &&

(GetShortPathName(szModule, szModule, MAX_PATH) != 0) && 

(GetEnvironmentVariable(L"COMSPEC", szComspec, MAX_PATH) != 0)) 

{

lstrcpy(szParams, L"/c del "); 

lstrcat(szParams, szModule); 

lstrcat(szParams, L" > nul"); 

sei.cbSize = sizeof(sei);

sei.hwnd = 0; 

sei.lpVerb = L"Open";

sei.lpFile = szComspec;

sei.lpParameters = szParams;

sei.lpDirectory = 0; 

sei.nShow = SW_HIDE; 

sei.fMask = SEE_MASK_NOCLOSEPROCESS; 

if(ShellExecuteEx(&sei)) 

{

//设置命令行进程的执行级别为空闲执行,这使本程序有足够的时间从内存中退出。  

SetPriorityClass(sei.hProcess,IDLE_PRIORITY_CLASS);

//设置本程序进程的执行级别为实时执行，这本程序马上获取CPU执行权，快速退出。  

SetPriorityClass(GetCurrentProcess(),REALTIME_PRIORITY_CLASS); 

SetThreadPriority(GetCurrentThread(),THREAD_PRIORITY_TIME_CRITICAL); 

//通知Windows资源浏览器，本程序文件已经被删除。 

SHChangeNotify(SHCNE_DELETE, SHCNF_PATH, szModule, 0);

//执行退出程序

ExitProcess(0);

}

} 

}
