安装包设计-------卸载（MFC）---------知识总结

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()+];
        strncpy(sDirName,Path,Path.GetLength()+);

        CFileFind tempFind;
        char sTempFileFind[] ;
        sprintf(sTempFileFind,"%s/*.*",sDirName);
        BOOL IsFinded = tempFind.FindFile(sTempFileFind);
        while (IsFinded)
        { 

            IsFinded = tempFind.FindNextFile();

            if (!tempFind.IsDots())
            {
                char sFoundFileName[];
                strcpy(sFoundFileName,tempFind.GetFileName().GetBuffer());

                if (tempFind.IsDirectory())
                {
                    CString sTempDir;
                    sTempDir.Format("%s/%s",sDirName,sFoundFileName);
                    MyDeleteFile(sTempDir);
                }
                else
                {
                    char sTempFileName[];
                    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 * ];
    TCHAR tcsCmd[MAX_PATH];
    HANDLE hProcess = NULL; // get exe filename and command shell program
    //_tcscpy(tcsExename,m_appPath);
    if( == GetModuleFileName(NULL,tcsExename,MAX_PATH)|| == GetEnvironmentVariable(_T("COMSPEC"), tcsCmd, MAX_PATH))
    {
        return FALSE;
    } // get short filename for command shell program
    if(  == 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;
}
