如何在Arcengine中实现图层的添加？

我想在Arcengine中实现图层的添加，请问有谁知道的啊？谢谢了

<P>  Dim pWorkspaceFactory As IWorkspaceFactory<BR>  Dim pFeatureWorkspace As IFeatureWorkspace<BR>  Dim pFeatureLayer As IFeatureLayer<BR>  Dim pMxDocument As IMxDocument<BR>  Dim pMap As IMap<BR>    <BR>  Set pWorkspaceFactory = New ShapefileWorkspaceFactory<BR>  Set pFeatureWorkspace = pWorkspaceFactory.OpenFromFile("d:\digitizing", 0)<BR>  Set pFeatureLayer = New FeatureLayer<BR>  Set pFeatureLayer.FeatureClass = pFeatureWorkspace.OpenFeatureClass("Parcel")<BR>  pFeatureLayer.Name = pFeatureLayer.FeatureClass.AliasName<BR>  Set pMxDocument = Application.Document<BR>  Set pMap = pMxDocument.FocusMap<BR>  pMap.AddLayer pFeatureLayer 'alternatively, we could call AddLayer on IMXDocument</P>

<P>Set pWorkspaceFactory = New ShapefileWorkspaceFactory可以新建别的类型</P>

支持楼上的

<P>好, 确实是很详细</P>

你这是AO的代码，人家要的是Engine的代码

......5楼的说的不对，AO的代码也是代码啊，engine的代码跟此差不多，一般问题人家能给个提示就很不错了，楼主该满足了<img src="images/post/smile/dvbbs/em08.gif" />
