c++ 调用外部程序exe-ShellExecuteEx

string file_path = s_run_dir+"\\ConsoleApplication1.exe";
    if (!myfile.IsFileExist(file_path))
    {

    }

    ShExecInfo.lpParameters = __T("D:\\a.txt D:\\b.txt D:\\c.txt");//传出去的参数
    ShExecInfo.lpDirectory = NULL;
    ShExecInfo.nShow = SW_SHOW;
    ShExecInfo.hInstApp = NULL;

    BOOL b_ret=ShellExecuteEx(&ShExecInfo);
    if (b_ret)
    {
        //等待调用启动的exe关闭，此处要设置成ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
        WaitForSingleObject(ShExecInfo.hProcess, INFINITE);

    }
    else
    {
        return 2;
    }
