在vb.net中以不同用户身份运行新进程
我目前使用本地方法在Vista中以不同用户的身份运行进程,但我无法逃避这种感觉,这是它的破解和不理想(除了这个事实,它摧毁UAC,崩溃我的应用程序与安全异常,并迫使我完全禁用UAC)。我的过程包括两个项目(于是两个EXE文件) - 一个“接口”和“发射短截线” - 而这里的过程:在vb.net中以不同用户身份运行新进程
- 用户已启动“Interface.exe的notepad.exe” 快捷方式
- Interface.exe有要求提供凭证的形式,他们想用
- Interace.exe使用的ProcessStartInfo创建LaunchStub.exe(LS)的实例作为新用户
- LS使用的ProcessStartInfo(带ShellExecute设置为true)启动所请求的文件,并且由于它已经以请求的用户身份运行,所以新进程也是如此。
我有两个步骤的过程的原因是我希望用户能够右键单击任何文件操作系统有(.EXE,.SQL,.MSC等)的默认行为和启动它,并且ProcessStartInfo仅在启用“UseShellExecute”的情况下支持该功能,但该开关阻止我使用新凭据,所以我一次只能执行一次。
这会导致一些问题 - 首先,用户必须已经存在于计算机上,这意味着他们必须先在本地登录。如果该用户没有本地配置文件,则所请求的应用程序有时会启动,但我得到注册表和配置文件例外,因为应用程序希望存在尚未存在的东西(例如注册表中的HKCU配置单元,而用户没有因为他们从未登录过)。
我知道我应该可以将我的应用程序的权限“提升”给他们请求的用户,启动我的新进程,然后撤消提升,但我无法找到一个好的代码示例为此,我不确定它会允许以完全不同的用户身份运行。这一切都有意义吗?我只是不禁觉得有更好的方法来做到这一点。
更新:我只是想some Impersonation code我在网上找到,但无济于事。当与ProcessStartInfo结合使用时,尽管我已经使用提供的凭证激活了模拟,但似乎仍然使用我当前的登录名启动进程,而不是我提供的登录名。
很可能您必须使用Win32 API创建自己的“shell”函数。
使用CreateProcessWithLogonW API,您可以在不同凭据下创建新进程,并可以选择加载用户配置文件信息。
在下面的代码片段,如果你更换
- 用户名 - 与您的用户名
- 域 - 与您的域名或 “vbNullString”
- 密码 - 与您的密码
- 参数4 - 取代0,'LOGON WITH PROFILE'加载指定的用户配置文件。
有关更多详细信息,请参阅CreateProcessWithLogonW API的文档。通过这条路线,您可以完全控制并全面负责启动应用程序。
再次,这只是一个示例,你可能需要玩一点它来做你想做的。

使用Runprogram()开始与用户程序/ PWÿ喜欢。程序仅指.exe,将参数写入“命令行”
如果要使用不同于当前正在运行的进程的凭据启动应用程序,则可以使用.Net 进程类。
this.Process = new Process();
this.Process.StartInfo.Arguments = "Arguments";
this.Process.StartInfo.FileName = "C:\your.exe";
this.Process.StartInfo.UserName = "UserName";
string password = "some password";
this.Process.StartInfo.Password.Clear();
foreach (char c in password)
{
this.Process.StartInfo.Password.AppendChar(c);
}
//allow the process to raise events
this.Process.EnableRaisingEvents = true;
this.Process.StartInfo.ErrorDialog = false;
//Method for handling the exit event
this.Process.Exited += new EventHandler(ApplicationProcess_Exited);
//Set the application directory as the current working directory
Environment.CurrentDirectory = System.IO.Directory.GetParent("C:\").ToString();
if (this.Process.Start())
{
// Do something on start
}
我会试试看看会发生什么。如果我可以做到这一点,而不必使用第二个EXE作为存根,那么我会很高兴,如果UAC启用时不会发生,我会处理提示。我尝试过之后我会成为bakc。 – SqlRyan 2009-01-26 20:08:08
@SqlRyan,并与启用UAC工作? – Jet 2013-03-31 13:59:57
