ArcGIS是Esri公司集40余年地理信息系统（GIS）咨询和研发经验，奉献给用户的一套完整的GIS平台产品，具有强大的地图制作、空间数据管理、空间分析、空间信息整合、发布与共享的能力。本人主要就AE搭建框架做简单的介绍
框架是指一个系统的全部或部分可复用设计，通常由一组抽象类和类之间的协助组成，其有几个特点。
1.模块化：应用框架可以从逻辑上划分为若干个不同的功能模块。
2.可重用性：代码的可重用性是衡量代码健壮性的一个标志，无论是函数，类，接口，还是其他更高层次的模型，都是为了提高其重用性。
3.可扩展性：可扩展性是应用框架一个最显著地标志，他意味着框架的能力具有可生长性。
其实arcmap也是一个可以扩展的框架，下面我们通过对arcmap的框架的研究来学习如何搭建自己的框架
首先我们打开arcmap编写一个简单的宏
宏命名为zoomin--实现一个简单的放大功能
2 Dim imxdocument As imxdocument 3 Dim penovlop As IEnvelope 4 Set imxdocument = ThisDocument 5 Set penovlop = imxdocument.ActiveView.Extent 6 penovlop.Expand 0.2, 0.2, True 7 imxdocument.ActiveView.Extent = penovlop 8 imxdocument.ActiveView.Refresh
保存宏，在菜单--自定义--自定义模式--工具条 新建工具条
我们在arcmap工具条看到一个新的工具栏，
在菜单--自定义--自定义模式--命令 找到 --宏 将我们刚才写的宏拖到菜单栏，这样我们就实现 了一个简单的功能
如此可见arcmap是一个可拓展的框架
2.通过实现接口或者抽象类的方法实现arcgis功能
如图安装了arcgis后 可以使用arcgis addin 来扩展功能
1 namespace ClassLibrary1 2 { 3 /// <summary> 4 /// Command that works in ArcMap/Map/PageLayout 5 /// </summary> 6 [Guid("86fbcea5-043b-404a-a00c-5c480b42f51e")] 7 [ClassInterface(ClassInterfaceType.None)] 8 [ProgId("ClassLibrary1.Command1")] 9 public sealed class Command1 : BaseCommand 10 { 11 // 将.net 注册为com函数 12 #region COM Registration Function(s) 13 [ComRegisterFunction()] 14 [ComVisible(false)] 15 static void RegisterFunction(Type registerType) 16 { 17 // Required for ArcGIS Component Category Registrar support 18 ArcGISCategoryRegistration(registerType); 19 20 // 21 // TODO: Add any COM registration code here 22 // 23 } 24 25 [ComUnregisterFunction()] 26 [ComVisible(false)] 27 static void UnregisterFunction(Type registerType) 28 { 29 // Required for ArcGIS Component Category Registrar support 30 ArcGISCategoryUnregistration(registerType); 31 32 // 33 // TODO: Add any COM unregistration code here 34 // 35 } 36 37 #region ArcGIS Component Category Registrar generated code 38 /// <summary> 39 /// Required method for ArcGIS Component Category registration - 40 /// Do not modify the contents of this method with the code editor. 41 /// </summary> 42 private static void ArcGISCategoryRegistration(Type registerType) 43 { 44 string regKey = string.Format("HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID); 45 MxCommands.Register(regKey); 46 ControlsCommands.Register(regKey); 47 } 48 /// <summary> 49 /// Required method for ArcGIS Component Category unregistration - 50 /// Do not modify the contents of this method with the code editor. 51 /// </summary> 52 private static void ArcGISCategoryUnregistration(Type registerType) 53 { 54 string regKey = string.Format("HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID); 55 MxCommands.Unregister(regKey); 56 ControlsCommands.Unregister(regKey); 57 } 58 59 #endregion 60 #endregion 61 62 private IHookHelper m_hookHelper = null; 63 public Command1() 64 { 65 // 初始化 66 // TODO: Define values for the public properties 67 // 68 base.m_category = ""; //localizable text 69 base.m_caption = ""; //localizable text 70 base.m_message = "This should work in ArcMap/MapControl/PageLayoutControl"; //localizable text 71 base.m_toolTip = ""; //localizable text 72 base.m_name = ""; //unique id, non-localizable (e.g. "MyCategory_MyCommand") 73 74 try 75 { 76 // 77 // TODO: change bitmap name if necessary 78 // 79 string bitmapResourceName = GetType().Name + ".bmp"; 80 base.m_bitmap = new Bitmap(GetType(), bitmapResourceName); 81 } 82 catch (Exception ex) 83 { 84 System.Diagnostics.Trace.WriteLine(ex.Message, "Invalid Bitmap"); 85 } 86 } 87 88 #region Overridden Class Methods 89 90 /// <summary> 91 /// Occurs when this command is created 92 /// </summary> 93 /// <param name="hook">Instance of the application</param> 94 public override void OnCreate(object hook) 95 { 96 //重写基类 97 if (hook == null) 98 return; 99 100 try 101 { 102 m_hookHelper = new HookHelperClass(); 103 m_hookHelper.Hook = hook; 104 if (m_hookHelper.ActiveView == null) 105 m_hookHelper = null; 106 } 107 catch 108 { 109 m_hookHelper = null; 110 } 111 112 if (m_hookHelper == null) 113 base.m_enabled = false; 114 else 115 base.m_enabled = true; 116 117 // TODO: Add other initialization code 118 } 119 120 /// <summary> 121 /// Occurs when this command is clicked 122 /// </summary> 123 public override void OnClick() 124 { 125 //全图显示 126 IMapControl2 Pmapcontrol2 = m_hookHelper as IMapControl2; 127 Pmapcontrol2.Extent = Pmapcontrol2.FullExtent; 128 Pmapcontrol2.Refresh(); 129 } 130 131 #endregion 132 } 133 } 生成dll文件，将其bin下面的 tlb.格式的文件 加载到 arcmap
