c++登录任务计划错误:没有完成帐户名和安全id之间的映射

Question

我正在尝试在windows 7上使用c++编写windows登录触发器任务。

我正在遵循这个微软教程。

但是我在保存任务到根文件夹时遇到了问题。:

//  ------------------------------------------------------
    //  Save the task in the root folder.
    IRegisteredTask *pRegisteredTask = NULL;
    hr = pRootFolder->RegisterTaskDefinition(
            _bstr_t( wszTaskName ),
            pTask,
            TASK_CREATE_OR_UPDATE, 
            _variant_t(L"Builtin\Administrators"), 
            _variant_t(), 
            TASK_LOGON_GROUP,
            _variant_t(L""),
            &pRegisteredTask);

hr出错的地方:没有完成账号名和安全id的映射

我还尝试用_variant_t(L"S-1-5-32-544")替换_variant_t(L"Builtin\Administrators")以消除语言硬编码问题，仍然没有运气。

我怎样才能使它工作?

Answer 1

在Windows启动时创建TaskScheduler任务的最终解决方案

(具有管理员权限，适用于Windows 7、8等)请注意，这不会在Windows启动时显示UAC弹出窗口"你确定以Admin权限运行此软件吗?"，这就是为什么TaskScheduler方法在这种情况下比老式的HKEY_LOCAL_MACHINE方法更有趣…

CurrentVersion 运行解决方案)

在本教程中有一些东西需要更新要使它工作:

• _variant_t(L"S-1-5-32-544")代替_variant_t(L"Builtin\Administrators")
• _CRT_SECURE_NO_WARNINGS
• 在vc++中，项目属性>配置属性>链接器在清单文件>UAC执行级别>requireAdministrator
• 删除已经过时的日期边界!
• 将hr = pLogonTrigger->put_UserId(_bstr_t(L"DOMAIN\UserName"));替换为硬编码的域用户名，或通过一些域用户名检测代码(我无法使其工作)，或只是注释这行，它为我工作!
• 为TASK_RUNLEVEL_HIGHEST添加一些代码
• 添加一些代码来启用任务，即使在笔记本电脑上运行电池(默认为"不运行任务如果电池")，和一些代码来防止。exe在一段时间后被杀死(默认情况下，任务将在开始运行72小时后停止)，等等。

然后你会得到著名的:

成功!任务注册成功。

我怀疑你的演示代码是xp时代的，还没有更新到符合Vista/Win7规则。

我更新了示例，以便在设置登录触发器后设置LUA设置，它似乎可以工作:

    hr = pLogonTrigger->put_UserId(_bstr_t(L"DOMAINusername"));
    if (FAILED(hr))
    {
        printf("nCannot add user ID to logon trigger: %x", hr);
        CoUninitialize();
        return 1;
    }

    //*** NEW**** Set the LUA settings
    CComPtr<IPrincipal>         pPrincipal;
    hr = pTask->get_Principal(&pPrincipal);
    if (SUCCEEDED(hr))
    {
        hr = pPrincipal->put_RunLevel(TASK_RUNLEVEL_LUA);
    }
    if (SUCCEEDED(hr))
    {
        hr = pPrincipal->put_GroupId(_bstr_t(L"Builtin\Administrators"));
    }
    if (FAILED(hr))
    {
        printf("nCannot set runlevel/groupid: %x", hr);
        CoUninitialize();
        return 1;
    }

如果您需要它在XP上运行，那么get_Principal调用很可能会失败，所以让失败通过。
