ArcGIS AddIN Sample学习笔记

1.AddInEditorExtension

功能描述:编辑器扩展,实现在编辑要素,对编辑事件的监听,及对新创建的要素的处理

核心代码:

void Events_OnStartEditing()
        {
            //Since features of shapefiles, coverages etc cannot be validated, ignore wiring events for them
            if (ArcMap.Editor.EditWorkspace.Type != esriWorkspaceType.esriFileSystemWorkspace)
            {
                //wire OnCreateFeature Edit event
                Events.OnCreateFeature += new IEditEvents_OnCreateFeatureEventHandler(Events_OnCreateChangeFeature);
                //wire onChangeFeature Edit Event
                Events.OnChangeFeature += new IEditEvents_OnChangeFeatureEventHandler(Events_OnCreateChangeFeature);
            }
        }
        //Invoked at the end of Editor session (Editor->Stop Editing)
        void Events_OnStopEditing(bool Save)
        {
            //Since features of shapefiles, coverages etc cannot be validated, ignore wiring events for them
            if (ArcMap.Editor.EditWorkspace.Type != esriWorkspaceType.esriFileSystemWorkspace)
            {
                //unwire OnCreateFeature Edit event
                Events.OnCreateFeature -= new IEditEvents_OnCreateFeatureEventHandler(Events_OnCreateChangeFeature);
                //unwire onChangeFeature Edit Event
                Events.OnChangeFeature -= new IEditEvents_OnChangeFeatureEventHandler(Events_OnCreateChangeFeature);
            }
        }

        void Events_OnCreateChangeFeature(ESRI.ArcGIS.Geodatabase.IObject obj)
        {
            IFeature inFeature = (IFeature)obj;
            if (inFeature.Class is IValidation)
            {
                IValidate validate = (IValidate)inFeature;
                string errorMessage;
                //Validates connectivity rules, relationship rules, topology rules etc
                bool bIsvalid = validate.Validate(out errorMessage);
                if (!bIsvalid)
                {
                    System.Windows.Forms.MessageBox.Show("Invalid Feature\n\n" + errorMessage);
                }
                else
                {
                    System.Windows.Forms.MessageBox.Show("Valid Feature");
                }
            }
        }

2.AddInExtensionPersist

功能描述:ArcMap扩展,实现对ArcMap事件的监听

比如启动,加载,保存等事件

3.AddInReportManager

功能说明:ESRI自带的一种报表导出方案

主要接口IReportDataSource,IReportTemplate

需要提前做好.rlf文件

4.AddInTimeSeriesGraph

功能描述:折线图 Tool

示例数据路径:C:\Program Files (x86)\ArcGIS\DeveloperKit10.1\Samples\data\StreamflowDateTime

相关接口

IIdentify :Provides access to members that identify features,相关矢量图层

IDisplayTable :Provides access to members that work with the display table associated with a standalone table. 该接口包含Joined 字段

IFeatureLayerDefinition:

ILookupSymbol .LookupSymbol ():Returns a reference to the renderer‘s symbol for the input feature.查询某个要素的Symbol

IDataGraphWindow2 :Provides access to members that control the DataGraph Window. ESRI自带的专题图窗口,可以使用下述代码调用显示

pDGWin = new DataGraphWindowClass();
pDGWin.DataGraphBase = pDataGraphBase;
pDGWin.Application = ArcMap.Application;
pDGWin.Show(true);

pDataGraphs.AddDataGraph(pDataGraphBase);

设置Title,坐标轴显示内容等

pDataGraphT = new DataGraphTClass();
                pDataGraphBase = (IDataGraphBase)pDataGraphT;

                // load template from <ARCGISHOME>\GraphTemplates\
                string strPath = null;
                strPath = Environment.GetEnvironmentVariable("ARCGISHOME");
                try
                {
                    pDataGraphT.LoadTemplate(strPath + @"GraphTemplates\timeseries.tee");
                }
                catch
                { }

                // graph, axis and legend titles. Substitute them for different input layer
                pDataGraphT.GeneralProperties.Title = "Daily Streamflow for Guadalupe Basin in 1999";
                pDataGraphT.LegendProperties.Title = "Monitoring Point";
                pDataGraphT.get_AxisProperties(0).Title = "Streamflow (cfs)";
                pDataGraphT.get_AxisProperties(0).Logarithmic = true;
                pDataGraphT.get_AxisProperties(2).Title = "Date";
                pDataGraphBase.Name = layerName;

设置绘图内容:

ISeriesProperties pSP = null;
            pSP = pDataGraphT.AddSeries("line:vertical");
            pSP.ColorType = esriGraphColorType.esriGraphColorCustomAll;
            pSP.CustomColor = pSymbol.Color.RGB;
            pSP.WhereClause = whereClause;
            pSP.InLegend = true;
            pSP.Name = gageID;

            pSP.SourceData = pLayer;
            pSP.SetField(0, timefldName);
            pSP.SetField(1, dataFldName);
            IDataSortSeriesProperties pSortFlds = null;
            pSortFlds = (IDataSortSeriesProperties)pSP;
            int idx = 0;
            pSortFlds.AddSortingField(timefldName, true, ref idx);

            pDataGraphBase.UseSelectedSet = true;

            ITrackCancel pCancelTracker = null;
            pCancelTracker = new CancelTracker();
            pDataGraphT.Update(pCancelTracker);

其他代码片段:

以下代码实现在检索时,先检测定义查询的Sql语句,如果有内容,则与新的查询语句And,没有,则直接使用新的查询语句

IFeatureLayerDefinition pFeatureLayerDef = null;
            pFeatureLayerDef = (IFeatureLayerDefinition)pLayer;
            string definitionExpression = null;
            definitionExpression = pFeatureLayerDef.DefinitionExpression;

            string whereClause = null;
            if (definitionExpression == "")
                whereClause = "[" + gageIDFldName + "] = ‘" + gageID + "‘";
            else
                whereClause = "[" + gageIDFldName + "] = ‘" + gageID + "‘ AND " + definitionExpression;

5.\AlgorithmicColorRamp

功能说明:

接口:

IContentsView: Provides access to members that control table of contents views,

Used to manage a contents view. The tabs in ArcMap‘s Table of Contents (TOC) are examples of a contents view.

示例用法:判断TOC中选中的内容

IContentsView ContentsView = null;
      ContentsView = ArcMap.Document.CurrentContentsView;
if (ContentsView is TOCDisplayView)
      {
        if (ContentsView.SelectedItem is DBNull)
        {
          //
          // If we don‘t have anything selected.
          //
          MessageBox.Show("SelectedItem is Null C#." + "Select a layer in the Table of Contents.", "No Layer Selected", MessageBoxButtons.OK, MessageBoxIcon.Information);
          return;
        }
        //
        // Get the selected Item.
        //
        VarSelectedItem = ContentsView.SelectedItem;
        //
        // Selected Item should implement the IGeoFeatureLayer interface - therefore we
        // have selected a feature layer with a Renderer property (Note: Other interfaces
        // also have a Renderer property, which may behave differently.
        //
        if (VarSelectedItem is IGeoFeatureLayer)
        {　　　　　　　//....　　　　　　}
