如何在VB NET中读取远程注册表？ [英] How do I Read Remote Registry in VB NET ?
问题描述
您好，我正在尝试获取许多远程PC的架构和操作系统。为了做到这一点，我正在查询Win32_OperatingSystem并解析O.S的Caption。以及用于阅读OSArchitecture的架构。在Windows XP中，这个值不存在，所以我认为读取HKLM \SYSTEM®\\ CurrentControlSet \Control \ Session Manager \ Environment \ SPROCESSOR_ARCHITECTURE就可以完成这个代码的技巧：
尝试
Dim co < span class =code-keyword> As 新 ConnectionOptions
co.Impersonation = ImpersonationLevel.Impersonate
co.Authentication = AuthenticationLevel .PacketPrivacy
co.EnablePrivileges = True
co.Username = username
co.Password = password
Dim 范围作为 新 ManagementScope（ \\& machine.Text& \root \cimv2，co）
scope.Connect（）
Dim environmentKey，asd2 As Microsoft.Win32.RegistryKey
Dim asd As String
environmentKey = RegistryKey.OpenRemoteBaseKey（RegistryHive .LocalMachine，machine.Text）
asd2 = environmentKey.OpenSubKey（ SYSTEM \ CurrentControlSet \ Control \ \\ _Session Manager \ Environment， True ）
asd = asd2.GetValue（ PROCESSOR_ARCHITECTURE）
Debug.Print（ asd： + asd）
environmentKey.Close（）
Catch ex As Exception
MessageBox.Show（ex.ToString）
< span class =code-keyword>结束 尝试
我的问题是：如果我尝试这个代码，我得到一个System.Security.SecurityException：不允许访问远程注册表
我是，我知道管理员用户名和密码。事实上，如果我运行一个简单的cmdkey / add：targetname / user：username / pass：password它可以工作。
那我为什么要运行cmdkey / add即使我已经在ConnectionOptions中指定了用户名和密码？
PS抱歉，我的英文不好
事情是你没有为注册表访问指定用户名和密码。
您尝试使用ManagementScope类，它只适用于WMI，而不适用于Registry类。
此外，如果您的代码运行在32位机器，你将有访问64位注册表的问题。
所以，不要使用注册表来执行此操作。请改用WMI。在WMI中有两种方法可以做到这一点。您可以在WMI中使用标准注册表提供程序，也可以查询 Win32_OperatingSystem [ ^ ]类来获取你正在寻找的信息。
Win32_OperatingSystem查询方法比注册表方法更好，因为你不会遇到问题从32位计算机访问64位注册表。
好的，谢谢Dave Kreskowiak和Google，我明白了：
Const HKEY_current_user 作为 字符串 = 80000002
Dim 选项作为 新 ConnectionO ptions
options.Impersonation = ImpersonationLevel.Impersonate
options.EnablePrivileges = True
options.Username = 。\ administrator
options.Password = my_password
Dim myScope 正如 新 ManagementScope（ \\\ \\& RemotePCHostname& \root \default，options）
Dim mypath 作为 新 ManagementPath（ StdRegProv）
Dim mc 作为 新 ManagementClass（myScope，mypath， Nothing ）
Dim inParams As ManagementBaseObject = mc.GetMethodParameters（ GetDWORDValue）
inParams（ hDefKey）= UInt32 .Parse（HKEY_current_user，System.Globalization.NumberStyles.HexNumber）' RegistryHive.LocalMachine
inParams（ sSubKeyName） = SYSTEM \ CurrentControlSet \Control\Session Manager \ Environment
inParams （ sValueName）= < span class =code-string> PROCESSOR_ARCHITECTURE
Dim outParams As ManagementBaseObject = mc.InvokeMethod（ GetStringValue，inParams， Nothing ）
如果（outParams（ ReturnValue）。ToString（）= 0 ）然后
MessageBox.Show（outParams（ sValue）。ToString （））
Else
MessageBox.Show（ 检索值时出错： + outParams（ ReturnValue）。 ToString（））
结束 如果
Hello, I'm trying to get the architecture and the operating system of many remote pcs. In order to do that i'm querying Win32_OperatingSystem and parsing the "Caption" for the O.S. and for the architecture im reading OSArchitecture . In Windows XP this value does not exists, so i thought that reading the HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\PROCESSOR_ARCHITECTURE would have done the trick like this code:
Try
Dim co As New ConnectionOptions
co.Impersonation = ImpersonationLevel.Impersonate
co.Authentication = AuthenticationLevel.PacketPrivacy
co.EnablePrivileges = True
co.Username = username
co.Password = password
Dim scope As New ManagementScope("\\" & machine.Text & "\root\cimv2", co)
scope.Connect()
Dim environmentKey, asd2 As Microsoft.Win32.RegistryKey
Dim asd As String
environmentKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, machine.Text)
asd2 = environmentKey.OpenSubKey("SYSTEM\CurrentControlSet\Control\Session Manager\Environment", True)
asd = asd2.GetValue("PROCESSOR_ARCHITECTURE")
Debug.Print("asd: " + asd)
environmentKey.Close()
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
My problem is: if im trying this code I get an System.Security.SecurityException: "Accessing remote registry not permitted"
I am, and i know the administrator username and password. In fact if I run a simple cmdkey /add:targetname /user:username /pass:password It works.
So why do I have to run a cmdkey /add even if i have alredy specified the username and password in the ConnectionOptions ??
P.S. Sorry for my bad English
The thing is you did NOT specify a username and password for the registry access.
You tried using the ManagementScope class, which only works with WMI, not the Registry classes.
Also, if your code is running on a 32-bit machine, you're going to have problems with accessing a 64-bit registry.
So, don't use the Registry to do this. Use WMI instead. There are two ways to do this in WMI. You can either use the Standard Registry Provider in WMI or you can query the Win32_OperatingSystem[^] class to get the information you're looking for.
The Win32_OperatingSystem query method is better than the registry method as you won't run into issues with accessing a 64-bit registry from a 32-bit machine.
All right, thank to Dave Kreskowiak and Google, i got it:
Const HKEY_current_user As String = "80000002" Dim options As New ConnectionOptions options.Impersonation = ImpersonationLevel.Impersonate options.EnablePrivileges = True options.Username = ".\administrator" options.Password = "my_password" Dim myScope As New ManagementScope("\\" & RemotePCHostname & "\root\default", options) Dim mypath As New ManagementPath("StdRegProv") Dim mc As New ManagementClass(myScope, mypath, Nothing) Dim inParams As ManagementBaseObject = mc.GetMethodParameters("GetDWORDValue") inParams("hDefKey") = UInt32.Parse(HKEY_current_user,System.Globalization.NumberStyles.HexNumber) 'RegistryHive.LocalMachine inParams("sSubKeyName") = "SYSTEM\CurrentControlSet\Control\Session Manager\Environment" inParams("sValueName") = "PROCESSOR_ARCHITECTURE" Dim outParams As ManagementBaseObject = mc.InvokeMethod("GetStringValue", inParams, Nothing) If (outParams("ReturnValue").ToString() = "0") Then MessageBox.Show(outParams("sValue").ToString()) Else MessageBox.Show("Error retrieving value : " + outParams("ReturnValue").ToString()) End If
