[求助]查询到图元后，如何最大化显示？已附代码

<P>Dim Ftrs As MapXLib.Features     '图元集合<BR>Dim Lyr As MapXLib.Layer<BR>Set Lyr = Map1.Layers("图层名称")<BR>Map1.Datasets.Add miDataSetLayer, Lyr<BR>Set Ftrs = Lyr.Search("查询条件")<BR>Map1.CenterX = Ftrs.Item(1).CenterX<BR>Map1.CenterY = Ftrs.Item(1).CenterY</P>
<P>查询到的结果已经可以移到地图中心，可是怎么样最大化显示呢？</P>
<P>高亮显示呢？</P>
<P>请帮忙解决，最好有代码？</P><img src="images/post/smile/dvbbs/em02.gif" />

<P> //居中发现的对象<BR> CMapXFeature Feature;<BR> CMapXLayer Layer=m_ctrlMapX.GetLayers().Item(m_LayerName);<BR> for(int i=0;i<50;i++)<BR> {<BR>    if(m_Layers==m_LayerName)<BR>     break;<BR> }<BR> Feature =Aftrs.Item(index+1); //Layer.AllFeatures().Item(i+1);<BR> m_ctrlMapX.SetZoom(50);//放大到一定比例,可以采用读取参数的方式<BR> m_ctrlMapX.SetCenterX(Feature.GetCenterX());<BR> m_ctrlMapX.SetCenterY(Feature.GetCenterY());</P>
<P> Layer.GetSelection().ClearSelection();<BR> Layer.GetSelection().Add(Feature);//高亮显示</P>
