ArcToolBox工具栏上添加自定义工具或命令

工具类：继承于BaseTool，若为命令，则继承于BaseCommand。

using ESRI.ArcGIS.ADF.BaseClasses;//该引用不同于AO9.2<br /> using ESRI.ArcGIS.Carto;<br /> using ESRI.ArcGIS.Controls;<br /> using System.Windows.Forms;<br /> using ESRI.ArcGIS.Geometry;<br /> using ESRI.ArcGIS.Geodatabase;<br /> using System;<br /> using WorldMap;<br /> public sealed class SearchData : BaseTool//若为命令，继承于BaseCommand<br /> {<br /> IMapControl3 mapControl;<br /> private IHookHelper m_HookHelper = new HookHelperClass();<br /> public SearchData()<br /> {<br /> //设置工具按钮的属性<br /> base.m_caption = “Search Data”;<br /> base.m_toolTip = “Search Data”;<br /> base.m_message = “Search Data”;<br /> base.m_name = “Search Data”;<br /> base.m_cursor = Cursors.Help;<br /> try<br /> {<br /> base.m_bitmap = new System.Drawing.Bitmap(Application.StartupPath + @”/icon/search3.bmp”);<br /> }<br /> catch<br /> {<br /> MessageBox.Show(this.Name+Environment.NewLine+”BitMap path is wrong!”);<br /> }</p> <p> }<br /> public override void OnCreate(object hook)<br /> {<br /> m_HookHelper.Hook = hook;<br /> if (hook is IToolbarControl)<br /> {<br /> IToolbarControl toolbarControl = (IToolbarControl) hook;<br /> mapControl = (IMapControl3) toolbarControl.Buddy;<br /> }<br /> }<br /> public override bool Enabled<br /> {<br /> get<br /> {<br /> if(m_HookHelper.FocusMap == null)<br /> return false;<br /> return true;<br /> }<br /> }<br /> //在MapControl上的事件<br /> public override void OnMouseDown(int Button, int Shift, int X, int Y)<br /> {<br /> //Identify功能<br /> try<br /> {<br /> IPoint pPoint;<br /> IFeatureLayer pFeatureLayer;<br /> ISpatialFilter pSpatialFilter;<br /> IFeatureSelection pFeatureSelection;<br /> ICursor pCursor;<br /> IFeature pFeature;<br /> ISelectionSet pSelectionSet;<br /> pPoint = this.mapControl.ToMapPoint(X, Y);<br /> pFeatureLayer = (IFeatureLayer)this.mapControl.get_Layer(3);<br /> pFeatureSelection = (IFeatureSelection)pFeatureLayer;<br /> pSpatialFilter = new SpatialFilterClass();<br /> pSpatialFilter.Geometry = (IGeometry)pPoint;<br /> pSpatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;<br /> this.mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);<br /> pFeatureSelection.SelectFeatures(pSpatialFilter, esriSelectionResultEnum.esriSelectionResultNew, true);<br /> this.mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);<br /> pSelectionSet = pFeatureSelection.SelectionSet;<br /> pSelectionSet.Search(null, false, out pCursor);<br /> pFeature = (IFeature)pCursor.NextRow();<br /> if (pFeature != null)<br /> {<br /> IFields pFields = pFeatureLayer.FeatureClass.Fields;<br /> DataForm dataForm = DataForm.NewForm();<br /> dataForm.textBox1.Text = pFeature.get_Value(pFields.FindField(“中文名称”)).ToString();<br /> dataForm.Show();<br /> this.mapControl.FlashShape(pFeature.Shape, 3, 200, null);<br /> }<br /> }<br /> catch (Exception e)<br /> {<br /> MessageBox.Show(e.Message);<br /> }<br /> }<br /> }<br />  

工具或命令添加到ArcToolBar上：

axToolbarControl1.AddItem(new SearchData(), 0, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly); 

效果图：

ps:从自定义工具或命令中访问MapControl，可以先从hook得到ArcToolBar，进而通过buddy属性得到mapcontrol。
