在CodeProject上看到一个Demo, 在服务中以当前用户身份启动一个程序.
跟帖的人指出了一些bug, 我整理了一下, 将跟帖人指出的bug在工程中修正.
他提供的类, 也有一个小bug, 没有被跟帖的人指出, 被我发现并修正.
这个Demo整理后, 被我用在项目中, 用起来效果还不错.
以当前登录用户的身份运行一个程序的好处:&
* 可以避免权限问题. e.g. 文件建立后, 当前用户打不开.
* 有些程序或部件运行, 是需要Windows窗口消息的, 不能直接在服务中运行.
工程下载点:&
编译环境: vs2010 vc++
&/// @todo ls 服务启动停止时, 检测服务是否已经在运行或停止的处理要加上, 提高效率.
/// 如果硬生生的启动停止服务时, 还要启动停止桌面上的程序, 在没有检测服务状态时, 要花费的时间多些.
// lsServiceForTest.cpp : Defines the entry point for the application.

win2003系统 ,一个应用程序，在计划任务中设定随系统启动而启动，以administrator远程桌面登录后，能在任务管理器的系统进程里看见（用户也是administrator)，但应用程序界面无法调出，请问如何调出应用程序界面？
有高手能给解答吗？
优秀技术经理
随系统启动的任务实际上是运行在一个特殊的用户账号SYSTEM的环境中，所以你是无法看见界面，正如两个同时登录到WINDOWS的用户无法看见对方的界面是一回事。
所以将任务改成随用户登录启动，就可以看见界面了。
记得点“引用/回复” 我才能跟踪你的问题与反馈。
因为专注，所以专业。}
