ShellExecuteEx写类似system函数

    封装成一个小的函数，来代替system函数
    void xsystem(const TCHAR* cmd, const TCHAR* par, int nShow)
   {
    SHELLEXECUTEINFO ShExecInfo = {0};
    ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
    ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
    ShExecInfo.hwnd = NULL;
    ShExecInfo.lpVerb = NULL;
    ShExecInfo.lpFile = cmd;
    ShExecInfo.lpParameters = par;
    ShExecInfo.lpDirectory = NULL;
    ShExecInfo.nShow = nShow;
    ShExecInfo.hInstApp = NULL;
    ShellExecuteEx(&ShExecInfo);
    WaitForSingleObject(ShExecInfo.hProcess,INFINITE);
   }

如关闭桌面程序
xsystem(_T("taskkill.exe"), _T("/f /im explorer.exe"), SW_HIDE);
