从远程节点读取注册表值 [英] Registry Value Read from Remote Node

问题描述

在局域网中，有5个连接的节点&启动m/c&之后，并非每个节点都引用密码.每个m/c中都安装了相同的操作系统(Windows XP Service Pack 3).但是我将从互联网上获取VB-6.0代码并运行此代码，而不从其他节点m/c中读取远程注册表项的值.
我尝试&试试这个问题，但是解决不了.
我该如何解决这个问题??
请给我Plz向我提供vb-6.0/vb.net编码...

------------------------------------------------

以下vb6.0代码如下:

In lan, there have 5 nodes connected & password not refered to every node after start the m/c & same OS(Windows XP Service pack 3) install in each m/c.But I will get VB-6.0 codes from internet and run this code, not read the value of remote registry key from other node m/c.
I try & try this problem, but can''t solve.
How can i solve this problem???
Plz Plz supply to me right vb-6.0/vb.net coding ...

推荐答案

您是否听说过WMI(Windows管理规范)?这是在另一台计算机上访问注册表的最简单方法之一.实际上，几乎所有资源都位于远程计算机上.

您也可以使用RegistryKey.OpenRemoteBaseKey方法.

Have you ever heard about WMI (Windows Management Instrumentation)? That is one of the easiest way to access the registry in a different machine. Actually almost all the resources on a remote machine.

Also you can use RegistryKey.OpenRemoteBaseKey method.
