●·● 在線幫助 & 本地幫助：

1. 通過在線幫助和本地幫助可以得到相同的內容，但是本地幫助速度更快，但是在線幫組效果更好，下面的圖示展示了如何將二者聯系起來，因為二者的排版還是存在一定的差別的！

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

●·● OMD（對象模型圖）：

1> AbstractClass：抽象類算一個超類，不能用來實例化一個對象，比如Line就是一個抽象類，其他的線是Line之上，Line給出了所有線的共同特性和方法。

　　符號：平面矩形，白色。

2> CoClass：這種類可以直接通過new方法實例化出一個對象。

　　符號：長方體，灰色。

3> Class：這種類不能直接new出一個對象，但是可以通過實例的屬性得到或者通過某個方法生成一個對象。

　　符號：長方體，白色。

4> Association（關聯）：表示一個類的實例可以和幾個其他類的實例相關聯，比如一個Line Symbol對象只能和一個線對象相關。

　　符號：灰色的線。

5> Type Inheritance（繼承）：是一個類可以通過繼承，得到其父類的屬性和方法，比如Line這個超類之上可以有其他類型的特定線類。

　　符號：空心三角箭頭。

6> Instantiation（實例化）：是某個類的某個方法可以實例化其他類的實例，比如:IWorkspaceFactory類的OpenFromFile()方法可以實例化一個IFeatureWorkspace類的實例。

　　符號：虛線箭頭。

7> Composition（組成）：是一個強制的關系，是一個類的實例包含了其他的類的實例，比如一個points會包含很多個point，當這么多的point的生命周期沒有結束，points對象就不能從內存中卸載掉。

　　符號：黑色菱形。

8> Inbounde Interface（入接口）：封裝了若干屬性和方法。

　　符號：空心圓。

9> Outbound Interface（出接口）：封裝的事件，即對象支持哪些事件的觸發。

　　符號：實心圓。

        class manager : programer
        {
            public void guanji1()
            {

            }
        }

        class Test2 : manager
        {

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Iperson Person = new Test();
            Person.xuexi();

            Programer.biancheng();
            Programer.xuexi();
            Programer.saodi();
            Imanager Manager = Programer as Imanager;
            Manager.guanji();
            Manager.biancheng();
            Manager.xuexi();
            Manager.saodi();

            person p = new person();
            p.xuexi1();
            dustman d = p as dustman;
            d.soadi1();
            d.xuexi1();
            programer pro = d as programer;
            pro.soadi1();
            pro.xuexi1();
            pro.biancheng1();
            manager m = pro as manager;
            m.soadi1();
            m.xuexi1();
            m.biancheng1();
            m.guanji1();
        }

　　接口只需提供方法，但是不用提供解決的途徑，解決的途徑在相應的類中定義，一個類可以同時集成多個接口，這些接口可以沒有任何關系，但是類只能繼承一個類，這里就體現出接口的優勢，不同的接口可以將類的方法有機的分離開，更好的實現管理！（@McDelfino拙見）

參考：

其中，Nest和Chicken 是聚合關系（Aggregation），既它們之間不共存。
          Wings和Chicken是組合關系（Composition)，它們共存，翅膀是雞的一部分，雞不在了翅膀也就沒了。
　　   Bird和Chicken是繼承關系（Type Inheritance），雞是鳥的一種。
　　   Egg和Chicken是實例化關系（Instantiation），雞蛋可以用雞的方法來實例化，雞下蛋實例化雞蛋。
　　   Bird是AbstractClass，不能實例化。
　　   Chicken和Nest是CoClass，可以通過New關鍵字來實例化。
　　   Egg和Wings是Class，可以通過其他實例的方法來實例化。

●·● IActiveView 接口：

1. Provides access to members that control the active view - the main application window.

　　This interface manages the main application window in ArcMap and all drawing operations.

　　In ArcMap, two objects implement【實現】 this interface: PageLayout and Map.  These two objects correspond to the two different views in ArcMap: layout and data view. Only one view can be active at a time and this is termed the active view. IMxDocument::ActiveView holds a reference to the current active view object (a Map or the PageLayout). For example, if the ArcMap application is in layout mode, IMxDocument::ActiveView returns an IActiveView reference to the PageLayout object.  Alternatively, if the application is in data view, this propery returns a reference【參考】 to the focus map. 

　　ArcMap has view commands which allow users to toggle【切換】 between layout view and data view. These commands appear on the View menu and on the scroll bar.

　　An ArcMap document can contain many Maps. Make sure you have the desired object when working with this interface. Otherwise, operations such as drawing may not be occurring in the application window as you expect. For example, a Map obtained through IMxDocument::Maps is not guaranteed to be the focus map. If you know you want a reference to the focus map, use IMxDocument::FocusMap.  Similarly, if you know you want a reference to the page layout, use IMxDocument::PageLayout instead. You can change the document's active view by setting IMxDocument::ActiveView. Learn more by reading the help for this property.

	OnFullExtentUpdated	Fires after the full extent (bounds) of the MapControl has changed. 當地圖的覆蓋范圍變化時觸發，例如，往地圖中新增加一個圖層，其覆蓋范圍大於原圖的范圍。
	OnKeyDown	Fires after a key is pressed on the keyboard.
	OnKeyUp	Fires after a pressed key is released.
	OnMapReplaced	Fires after the Map contained by the MapControl has been replaced. 當 MapControl 的 mxd 文件替換時候觸發事件！【鷹眼】
	OnMouseDown	Fires when the user presses any mouse button while over the MapControl. 在 MapControl 上面點擊鼠標上面任何一個鍵觸發事件！ e.button = 1　　表示 左鍵。 e.button = 2　　表示 右鍵。 e.button = 4　　表示 中鍵。 e.x　　表示 像素橫坐標。 e.y　　表示 像素縱坐標。 e.MapX　　表示 地圖橫坐標。 e.MapY　　表示 地圖縱坐標。 label1.Text = "MapX:" + string.Format("{0:0.00000}", e.mapX).PadLeft(10) + "°"; label2.Text = "MapY:" + string.Format("{0:0.00000}", e.mapY).PadLeft(10) + "°"; label3.Text = "X:" + e.x.ToString().PadLeft(5); label4.Text = "Y:" + e.y.ToString().PadLeft(5);
	OnMouseMove	Fires when the user moves the mouse over the MapControl. 當鼠標在 MapControl 上面漫游的時候觸發！
	OnMouseUp	Fires when the user releases a mouse button while over the MapControl.
	OnOleDrop	Fires when an OLE drop action occurs on the MapControl.
	OnSelectionChanged	Fires when the current selection changes.

●·● ToolbarControl 類：

1. ToolbarControl 包括6個對象及相關接口: ToolbarControl 、ToolbarItem 、ToolbarMenu 、CommandPool 、CustomizeDialog 、MissingCommand。ToolbarControl 要與一個"伙伴控件"協同工作。通過ToolbarControl 屬性頁設置，或者在駐留ToolbarControl 的容器被顯示時用SetBuddyControl 方法通過編程設置。

　　ToolbarControl 的每個"伙伴控件"都實現了 IToolbarBuddy 接口，這個接口用於設置"伙伴控件"的 CurrentTool 屬性。如通過設置 MapControl 作為其"伙伴控件"，當用戶單擊該 ToolbarControl 上的"拉框放大" 工具時，該放大工具就會成為 MapControl 的 CurrentTool 。放大工具的實現過程是:通過ToolbarControl 獲取其"伙伴控件"，然后在 MapControl 上提供顯示終端用戶按動鼠標所畫的框，並改變 MapControl 的顯示范圍。ToolbarControl 一般要與一個"伙伴控件"協同工作，並有一個控件命令選擇集，以便快速提供功能強大的GIS 應用程序。ToolbarControl 不僅提供了部分用戶界面，而且還提供了部分應用程序框架。ArcGIS Desktop 應用程序，如 ArcMap 、ArcGlobe 和 ArcScene 等具有強大而靈活的框架，包括諸如工具條、命令、菜單、泊靠窗口和狀態條等用戶界面組件，這些框架使終端用戶可以通過改變位置、添加利刪除這些用戶界面組 件來定制應用程序。

　　ArcGIS Engine 提供了幾套使用 ArcGIS 控件的命令，以便執行某種特定動作，開發人員可通過創建執行特定任務的定和l命令來擴展這套控件命令。所有的命令對象都實現了 ICommand 接口，ToolbarControl 在適當的時候要使用該接口來調用方法和訪問屬性。在命令對象被駐留到 ToolbarControl 后，就會立即調用 ICommand: :OnCreate 方法，這個方法將一個句柄(Handle) 或鈎子(hook)傳遞給該命令操作的應用程序。命令的實現一般都要經過測試，以查看該鈎子(hook)對象是否被支持.如果不支持則該鈎子自動失效，如 果支持，命令則存儲該鈎子以便以后使用。ToolbarControl 使用鈎子(hook) 來聯系命令對象和..伙伴控件"，並提供了屬性、方法和事件用於管理控件的外觀，設置伙伴控件，添加、刪除命令項，設置當前工具等。 ToolbarControl 的主要接口有: IToolbarControl 、IToolbarControlDefault、IToolbarControlEvents。

　　(1) IToolbarControl: 該接口是任何與 ToolbarControl 有關的任務的出發點，如設置"伙伴控件"的外觀，設置伙伴控件，添加或去除命令、工具、菜單等。

　 　(2) ITooJbarControlDefault: 該接口是自動暴露的缺省的 dispatch 接口，該接口的屬性和方法與 ToolbarControl 的最高版本主接口的屬性、方法相同。例如目前版本中的 IToolbarControlDefault 等同於 IToolbarControl .但在今后的新版本中，可能會變為 IToolbarControl2 。在開發中使用 IToolbarControlDefault 接口，能夠保證總是訪問到最新版本的ToolbarControl。

　　(3) IToolbarControlEvents: 該接口是一個事件接口，定義了 ToolbarControl 能夠處理的全部事件，如 OnDoubleClick、OnltemClick、OnKeyDown 等。

　　在ToolbarControl 上可以駐留以下3 類命令。

　 　(1)實現了響應單擊事件的 ICommand 接口的單擊命令。用戶單擊事件， 會導致對 ICommand : :OnClick 方法的調用，並執行某種動作。通過改變ICommand: :Checked 屬性的值，簡單命令項的行為就像開關那樣。單擊命令是可以駐留在菜單中的惟一命令類型。

　　(2)實現了 ICommand 接口和 ITool 接口、需要終端用戶與"伙伴控件"的顯示進行交互的工具。ToolbarControl 維護 CurrentTool 屬性。當終端用戶單擊ToolbarControl 上的工具時，該工具就成為 CurrentTool。ToolbarControl 會設置"伙伴控件"的 CurrentTool 屬性。當某個工具為 CurrentTool 時，該工具會從"伙伴控件"收到鼠標和鍵盤事件。

　 　(3)實現了 ICommand 接口和 IToolControl 接口的工具控件。這通常是用戶界面組件。ToolbarControl 駐留了來自 ItoolControl: hWnd 屬性窗口句柄提供的一個小窗口，只能向 ToolbarControl 添加特定工具控件的一個例程。

　　可以使用3 種方法向 ToolbarControl 添加命令，第1 種是指定唯一識別命令的一個UID ，第2 種是指定一個 progID，第3 種是給 AddToolbarDef 方法提供某個現有命令對象的一個例程。下面給出樣例代碼。

//Add a toolbardef by passing a UIO
 UID uID = new UIDClass();
            uID.Value = "esriControls.ControlsMapNavigationToolbar";
            axToolbarControl1.AddToolbarDef(uID, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly);
            
            //Add a toolbardef by passing a ProgID
 string progID = "esriControls.ControlsMapNavigationToolbar";
            axToolbarControl1.AddToolbarDef(progID, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly);
            
            //Add a toolbardef by passing an IToolbarDef
 IToolBarDef toolBarDef = new ControlsMapNavigationToolbarClass();
            axToolbarControl1.AddToolbarDef(toolBarDef, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly);

　 　ToolbarControl 更新命令的使用。默認情況下，ToolbarControl 每半秒鍾自動更新一次，以確保駐留在 ToolbarControl 上的每個工具條命令項的外觀與底層命令的 Enabled 、Bitmap 、Caption 等屬性同步。改變 Updatelnterval 屬性可以更改更新頻率。Updatelnterval 為0會停止任何自動發生的更新，可以通過編程調用 Update 方法以刷新每個工具條命令項的狀態。

　　在應用程序中首次調用 Update 方法時，ToolbarControl 會檢查每個工具條命令項的底層命令的 ICommand: :OnCreate 方法是否已經被調用過，如果還沒有調用過該方法，該 ToolbarCommand 將作為鈎子被自動傳遞給 ICommand: :OnCreate 方法。
