在arcgis engine中如何实现点击图元查询其属性功能？

  On Error GoTo eh       '  Dim pMxDoc As IMxDocument    Dim pActiveView As IActiveView    Dim pIdentifyDialog As IIdentifyDialog    Dim pIdentifyDialogProps As IIdentifyDialogProps    Dim pEnumLayer As IEnumLayer    Dim Player As ILayer

  '  Set pMxDoc = Application.Document    Set pActiveView = GetMap() 'pMxDoc.FocusMap

  'Create a new IdentifyDialog and associate it    'with the focus map and the map's display    Set pIdentifyDialog = New IdentifyDialog    Set pIdentifyDialogProps = pIdentifyDialog 'QI    Set pIdentifyDialog.Map = GetMap()    Set pIdentifyDialog.display = pActiveView.ScreenDisplay       'Clear the dialog on each mouse click    pIdentifyDialog.ClearLayers       'Perform an identify on all of the layers the dialog    'says are searchable    Set pEnumLayer = pIdentifyDialogProps.Layers    pEnumLayer.Reset    Set Player = pEnumLayer.Next

  Do While Not Player Is Nothing       pIdentifyDialog.AddLayerIdentifyPoint Player, x, y              Set Player = pEnumLayer.Next    Loop       pIdentifyDialog.Show

有没有点例子?

这个很简单：

iSpatialFilter:将Geometry的属性设为一个点。

之后用IFeatureLayer或者IFeatureClass的Search方法就可以了
