AE开发问题

请问怎样在AE中实现如ArcMap的toc中的点击左键弹出Symbol Selector对话框，点击右键弹出ColorPalette

<P> Private Sub TOC_OnMouseDown(ByVal sender As Object, ByVal e As ESRI.ArcGIS.TOCControl.ITOCControlEvents_OnMouseDownEvent) Handles TOC.OnMouseDown<BR>    Dim pOther As Object = Nothing<BR>    Dim pItem As esriTOCControlItem<BR>    Dim pIndex As Object = Nothing<BR>    Dim pMap As IMap = Nothing<BR>    Dim pLayer As ILayer = Nothing</P>
<P>    'Determine what kind of item has been clicked on<BR>    TOC.HitTest(e.x, e.y, pItem, pMap, pLayer, pOther, pIndex)<BR>    If e.button = 2 Then</P>
<P>      'Only layer items can have their labels edited<BR>      If pItem = esriTOCControlItem.esriTOCControlItemLayer Then<BR>        TOCPopupMenu.ShowPopup(Control.MousePosition)<BR>      End If<BR>    ElseIf e.button = 1 Then<BR>      If pItem = esriTOCControlItem.esriTOCControlItemLegendClass Then<BR>        If TypeOf pOther Is ILegendGroup Then<BR>         ''Todo sth<BR>        End If<BR>      End If<BR>    End If</P>
<P>  End Sub</P>

<P>有谁对ae开发了解多点的，请多写些在上面</P>

使用ae９.2就有Symbol Selector对话框
