MMC Technology Summary
MMC is a Multiple Document Interface(MDI) shell user interface(UI) for the integration of modularized administration tools that are implemented as snap-ins. This means that it is possible to have multiple windows, all attached to the same management console. It is a tool that hosts snap-in programs that provide the actual functionality. Snap-in programs are designed to perform a specific type of application or object. A snap-in can be loaded as needed into an MMC Console to create a customized management environment. The combined set of snap-in specified in the console can be saved as an .MSC file, which can be considered an MMC tool, is also referred to as an MMC console. With the capability to Add/Remove snap-ins, it is possible to create specific consoles that match the skill level and job description of the administrator who is intended to operate the console. The .MSC file makes the console portable. Each sap-in operate within the MMC console structure, which consists of three panes. The managed entities map to a hierarchy of nodes that is displayed as a tree in the tree pane. The scope of a snap-in may include network resources, as well as objects, views, and actions.

MMC Programming Elements
It is useful to be familiar with programming elements offered by MMC before you undertake the task of designing a snap-in. The purpose of the MMC3.0 SDK is to design snap-in. The snap-in contains the actual workings of a management task. It is designed to run within the context of the MMC. The MMC3.0 SDK facilitates the design of a snap-in to encapsulate either a specific management task or a set of operations. It allows the snap-in development to focus on the objects to be managed and the methods used to manage the objects. A snap-in can either be a stand-alone snap-in, thereby providing independent programmatic functionality, or it can be extension snap-in that extends the operations of a specific snap-in, and is dependent on the parent snap-in to operate.
The following are useful decision steps to consider before starting:
1. Identify the management space and determine what type of snap-in best suits your needs.
2. Layout the namespace, and decide what objects or containers belong in it.
3. Design the UI to present information about a managed objects.
4. Define the management tasks for each object in the namespace
5. Start writing the snap-in code using the MMC3.0 Managed code framework.

|
Snap-in |
The Snap-In class provides the abstraction for the core binding of a snap-in dynamic-link library (DLL) and provides the initial instantiation point of the snap-in code. |
|
Use of Attributes Programming Model |
MMC uses attributes to store essential metadata. |
|
Scope Node |
The Scope Node class provides the basic icon and name for a node in the tree pane. |
|
Result Node |
Unlike scope nodes, result nodes cannot have children. They are used solely to populate an instance of MmcListView. |
|
Actions |
Custom Actions will show in the context menu and in the actions pane. |
|
Standard Verbs |
Standard verbs can be set for both scope nodes and the selected items in a view to handle the most common actions such as a Refresh. |

How to test the MMC program
To test your snap-in, run MMC 3.0 (mmc.exe) and use the Add/Remove Snap-In menu option to add your snap-in from the installed snap-ins list. Note that when MMC has loaded your snap-in, the .dll is in use, and cannot be re-compiled until you either remove it from the console, or close MMC.
If you wish to set breakpoints or walk through your code, you can instruct Visual Studio to run MMC for you, giving you access to your managed snap-in code. Under the ‘Debug’ settings in the project properties, select the ‘Start external program’ radio button and enter the full path to mmc.exe. When the snap-in runs, you will be able to debug it.
1. 首先应该先将你写好的snap-in程序进行编译，即Build一下，此时你的应用程序Bin"Bug目录先就会生成关于你这个应用程序的.dll文件。
2. 然后，如果你的机器上还没有安装.NET Framework的话，请安装；如果安装，请按照这个目录C:"Windows"Microsoft.NET"Framework"v2.0.50727"Installutil.exe文件拷贝到你应用程序的Bin"Debug目录下，例如：E:"MMC"InitializationWizardSnapIn.cs"InitializationWizardSnapIn.cs"bin"Debug
3. 请以管理员身份运行【命令提示符】，进入你应用程序Bin"Debug目录下，然后执行命令：
Installutil -i xxx.dll.具体如下图所示：
4. 安装成功之后，然后执行mmc.exe命令，打开控制台程序
5. 点击【文件】——【添加/删除管理单元】
6. 将你刚刚生成的snap-in程序添加进去，如：
7. 保存此控制台，保存路径，最好是保存在你应用程序的Bin"Debug目录下，然后进行如下设置：
8. 然后就可以加断点，运行你的MMC应用程序了。
MMC Basic Class
|
Class |
Description |
|
FormView |
Provides a standard MMC WinForm view. It allows the results pane to be populated with a WinForm control. All classes that are derived from this type must have a public default constructor defined. |
|
MmcListView |
Provides a standard MMC view that allows the results pane to be populated with a list of items. All classes that are derived from this type must have a public default constructor defined. |
|
Node |
Provides the abstract base class for all MMC-related node types. It encapsulates common functionality such as associated display text, node type qualification, and a mechanism to expose the actions that are associated with the node |
|
ScopeNode |
Represents an item that is added by a snap-in to a list view. |
|
SelectionData |
This is a sealed class that contains data about selected items in a view. |
|
SnapIn |
Provides the main entry point for the creation of a snap-in. In the managed framework in MMC, a minimal amount of code that uses this class is required to build a simple snap-in that has core functionality. The NamespaceSnapInBase class from which the SnapIn class is derived, provides an implementation of functionality that is common to both standalone and extension snap-ins. |
