关注此link ，我在我的 C# 解决方案中实现了 WTSQueryUserToken 并从我的 Windows 服务的 OnStart 调用了 CreateProcessAsUserWrapper.LaunchChildProcess("app_path") 方法以 "LocalSystem" 运行。它能够启动可与桌面交互的进程，但适用于 Windows Professional 而不是 Windows Ultimate。我在 Windows Professional 64 位上尝试过它，它能够在用户以交互方式登录时成功启动进程，但在 Windows Ultimate 64 位版本上，CreateProcessAsUser 方法返回 false并且可以看到该服务在 SCM 上运行，而该进程不是。
我的进程是一个 win 表单应用程序，需要使用当前登录的用户帐户运行以进行桌面交互并使用 InteropServices。会不会是框架问题？如何解决问题？请帮忙。
编辑:
两台机器都运行 Windows 7 64 位。我在 CreateProcessAsUser 之后添加了以下代码以获取错误代码，它返回“请求的操作需要提升”作为错误。
string errorMessage = new Win32Exception(Marshal.GetLastWin32Error()).Message;
它只发生在 Windows 7 Ultimate 中，而不发生在 Windows 7 Professional 中。我需要为每个登录用户运行我的进程，这就是为什么我认为我不能改用 CreateProcessWithLogonW 方法的原因。我现在该如何解决此提升权限问题？
编辑:
有 2 个 app.manifest 文件，一个在服务项目中，另一个在 win 表单(进程)项目中。我删除了这两个文件，用 WiX 构建了 msi 并再次测试。现在它已在每台机器上成功运行，每个登录的用户帐户都会启动该过程。但是，现在造成了一个问题。实际上我需要在 windows/system 文件夹下写一些日志，我现在不能这样做。我正在从进程中抛出“UnauthorizedAccessException”。此外，除管理员外，不允许任何用户停止或卸载该进程，但在这种情况下，用户可以启动任务管理器并从那里结束该进程，因为它是使用相应的用户帐户运行的。是否可以使用用户帐户运行该进程但具有提升的权限，以便我可以在 windows/system 文件夹下写入我的日志并防止用户在未经管理员许可的情况下停止该进程？至少解决第一个问题，即在系统文件夹下写入日志文件对我来说非常重要。
编辑:
添加 SetTokenInformation 和 DuplicateTokenEx 后，我的服务无法启动应用程序，日志 "SetTokenInformation() 返回 FALSE。错误:A客户不拥有所需的特权”。我提供了完整的代码，请查看我是否已正确更新所有步骤。

正如我在之前的编辑中提到的，在添加 DuplicateTokenEx 和 SetTokenInformation 之前，该服务能够运行该应用程序，但无法在 System32 文件夹下登录。为实现这一点，我更新了上面的代码，现在 SetTokenInformation() 方法显示权限错误。
编辑: 最后，该服务可以在登录用户帐户上启动我的进程，并将我的所有日志文件写入正确的用户应用程序数据路径。我已经删除了 SetTokenInformation。使用 CreateEnvironmentBlock() 方法跟踪代码帮助进程获得单独的用户环境并检索用户应用程序数据路径。
int dwCreationFlags = DETACHED_PROCESS;
IntPtr pEnv = IntPtr.Zero;
if (CreateEnvironmentBlock(ref pEnv, hToken, true))
{
dwCreationFlags |= CREATE_UNICODE_ENVIRONMENT;
}
else
{
pEnv = IntPtr.Zero;
}
bool ChildProcStarted = CreateProcessAsUser(
hToken, // client's access token
ChildProcName, // file to execute
null, // command line
ref saProcess, // pointer to process SECURITY_ATTRIBUTES
ref saThread, // pointer to thread SECURITY_ATTRIBUTES
false, // handles are not inheritable
dwCreationFlags, // creation flags
pEnv, // pointer to new environment block
null, // name of current directory
ref tStartUpInfo, // pointer to STARTUPINFO structure
out tProcessInfo // receives information about new process
);
最佳答案
总结:
最初的问题是目标可执行文件被配置为需要 UAC 提升，但必须在用户的上下文中运行，即使用户不是管理员。这与它是从服务启动的事实没有直接关系，但这是一个复杂的因素，因为它意味着启动应用程序的尝试失败，而不是导致提升对话框。解决方案是将应用程序 list 中的 requestedExecutionLevel 从 requireAdministrator 更改为默认值 asInvoker。
当应用程序被重新配置为不需要 UAC 提升时，它无法正常运行，因为它试图将日志文件写入全局文件夹。解决方案是将日志文件写入适合每个用户的位置。
最后一个问题是应用程序在从服务启动时没有正确找到每个用户的位置。这是因为它得到的是服务环境 block 的副本，而不是适合用户的副本。决议是使用 CreateEnvironmentBlock()生成合适的环境 block 并将其作为 CreateProcessAsUser 的 lpEnvironment 参数传递。
关于c# - 对于某些版本的 Windows，Windows 服务无法在用户使用 WTSQueryUserToken 登录时启动交互过程，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28674344/

很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于
我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
