1、删除目录及其下所有文件

bool MyDeleteFile(CString Path) {                                                     //     SHFILEOPSTRUCT FileOp={0}; //     FileOp.fFlags = FOF_ALLOWUNDO | //允许放回回收站//         FOF_NOCONFIRMATION; //不出现确认对话框//     FileOp.pFrom = Path; //     FileOp.pTo = NULL; //一定要是NULL//     FileOp.wFunc = FO_DELETE; //删除操作//     return SHFileOperation(&FileOp) == 0;         char* sDirName = new char[Path.GetLength()+1];        strncpy(sDirName,Path,Path.GetLength()+1);        CFileFind tempFind;         char sTempFileFind[200] ;        sprintf(sTempFileFind,"%s/*.*",sDirName);        BOOL IsFinded = tempFind.FindFile(sTempFileFind);        while (IsFinded)        {             IsFinded = tempFind.FindNextFile();            if (!tempFind.IsDots())            {                 char sFoundFileName[200];                strcpy(sFoundFileName,tempFind.GetFileName().GetBuffer(200));                if (tempFind.IsDirectory())                 {                     CString sTempDir;                    sTempDir.Format("%s/%s",sDirName,sFoundFileName);                    MyDeleteFile(sTempDir);                 }                else                {                     char sTempFileName[200];                    sprintf(sTempFileName,"%s/%s",sDirName,sFoundFileName);                    DeleteFile(sTempFileName);                 }            }        }        tempFind.Close();        if(!RemoveDirectory(sDirName))         {             return false;        }        return true;}

2、删除应用程序自身

BOOL DeleteApplicationSelf(){    TCHAR tcsExename[MAX_PATH];    TCHAR tcsParam[MAX_PATH * 2];     TCHAR tcsCmd[MAX_PATH];    HANDLE hProcess = NULL; // get exe filename and command shell program     //_tcscpy(tcsExename,m_appPath);    if(0 == GetModuleFileName(NULL,tcsExename,MAX_PATH)||0 == GetEnvironmentVariable(_T("COMSPEC"), tcsCmd, MAX_PATH))    {        return FALSE;    } // get short filename for command shell program     if( 0 == GetShortPathName(tcsExename, tcsExename, MAX_PATH))     {        return FALSE;    } // create a command process, set its priority, then start it.    STARTUPINFO si;     PROCESS_INFORMATION pi;     ZeroMemory( &si, sizeof(si) );    si.cb = sizeof(si);     si.dwFlags = STARTF_USESHOWWINDOW;    si.wShowWindow = SW_HIDE;    ZeroMemory( &pi, sizeof(pi) );    _stprintf(tcsParam, _T("%s /c del %s"), tcsCmd, tcsExename);    if(!CreateProcess(NULL,tcsParam,NULL,NULL,FALSE,CREATE_SUSPENDED, NULL,NULL,&si,&pi))     {         return FALSE;        // GetLastError();    } // heigthen priority of the current process     SetPriorityClass(GetCurrentProcess(), HIGH_PRIORITY_CLASS); // set file attribute to normal     SetFileAttributes(tcsExename, FILE_ATTRIBUTE_NORMAL); // depress priority of command process, then start it     SetPriorityClass(pi.hProcess, IDLE_PRIORITY_CLASS);     ResumeThread(pi.hThread);     return TRUE;}
