如何使用Microsoft Management Console编写Snap-in(一)

如果我们自己的应用程序使用Microsoft Management Console(MMC)设置界面，可能会显得我们的应用程序更专业。
下面我来介绍一下如何使用.NET 2.0编写基于Microsoft Management Console 3的Snap-in。
如果你要使用.NET 1.1编写对于MMC2的Snap-in，可以参考MMC.NET。
目前Microsoft Management Console 3还只是RC1，建议不要在正式生产环境中使用，本文只作学习使用。
可以在微软的网站下载Microsoft Management Console 3.0 Pre-Release (RC1 Refresh)的对应版本。
MMC3支持Windows 2000以上的操作系统，Vista自带MMC3。

我以下的说明是以Windows XP Pro with sp2 英文版为基础的。

1. 安装WindowsXP-KB907265-x86-ENU.exe，安装之后会在"C:\Windows\System32\"目录下多出两个文件：microsoft.managementconsole.dll

和mmcfxcommon.dll，最好将这两个文件加入GAC，省得以后麻烦。
2. 使用Visual Studio 2005 建立一个Windows Class Library Project，起名为"TestMMC3"，并将microsoft.managementconsole.dll加入引用。
3. 写代码

using System;
 using System.Collections.Generic;
 using System.Text;
 using System.ComponentModel;
 using Microsoft.ManagementConsole;namespace TestMMC3
 { 
 
     //为一些安装工具提供的入口。比如InstallUtil.exe
     [RunInstaller(true)]
     public class InstallUtilSupport : SnapInInstaller
     { 
 
     }    //每一个Snap-In都要有一个继承与SnapIn的类，这个类必须构建一个根节点，并要为根节点命名。
     [SnapInSettings("{784DEE12-EC06-4a72-87CA-C11D826A0657}",
     DisplayName = "- Simple SnapIn Sample",
     Description = "Simple Hello World SnapIn")]
     public class SimpleSnapIn : SnapIn
     { 
 
         public SimpleSnapIn()
         { 
 
             this.RootNode = new ScopeNode();
             this.RootNode.DisplayName = "Hello World";
         }
     } 
 }

3. 编译（废话）
4. 在编译目录运行installutil TestMMC3.dll命令，如果没有将mmcfxcommon.dll加入GAC，就需要将TestMMC3.dll放到"C:\Windows\System32\"中。

The transacted install has completed.

Instillutil.exe会在HKLM/Software/Microsoft/MMC/NodeTypes/SnapIns创建一个Key。

5. 在"Run"中运行mmc

单击File->Add/Remove Snap-in

单击"Add"

选择"- Simple SnapIn Sample"
