关于arcengine加载注记图层的问题

<DIV>我把注记图层单独转换出来，放在geodatabase里面，请问如何将它加载到mapcontrol控件里面，谢谢：）<BR>这是现在的代码，可是还是没有加载成功，那位可以提供更加详细的代码，不胜感激。<BR>Dim layerclass As IAnnotationLayerFactory<BR>        Dim layer As IGeoFeatureLayer<BR>        layerclass = Workspace.OpenFeatureClass("jcdl_shxzqhAnno")<BR>        layer = New FeatureLayer<BR>        layer.FeatureClass = layerclass<BR>        layer.Name = "上海市行政区划注记层"<BR>        axMapControl1.Map.AddLayer(layer)<BR>        axMapControl1.ActiveView.Refresh()</DIV>

<P>注记图层的打开，不是这样收拾的。帮助里面有说怎么打开注记的。</P>
<P>顺便看我写的吧，能顺利打开注记图层的。</P>

<P>IFeatureClassPtr ipFClass;<BR> HRESULT result = ipFeatureWorkspace->OpenFeatureClass(<BR>  CComBSTR(layer.strSdeLayer), ;ipFClass);<BR> if (FAILED(result) || NULL == ipFClass) {<BR>  TRACE("\n缺少图层表：%s", layer.strSdeLayer);<BR>  return FALSE;<BR> }</P>
<P> esriFeatureType ftype;<BR> result = ipFClass->get_FeatureType(;ftype);<BR> if (FAILED(result)) {<BR>  AfxMessageBox("查询SDE图层类型出现错误。");<BR>  return FALSE;<BR> }</P>
