在ArcEngine开发中,Scenecontrol里怎样实现保存和另存?

<P>找半天没发现scenecontrol里没有Save方法,也没有类似在Mapcontrol里的Mapdocument东东!</P>
<P>在这里可以学到不少东西,欢迎大家讨论!</P>
<P>下面是Mapcontrol的save,供大家参考!</P>
<P>    Public Overrides Sub OnClick()<BR>        Dim pMapControl As IMapControl3<BR>        pMapControl = m_pHookHelper.Hook</P>
<P>        Dim pActiveView As IActiveView<BR>        pActiveView = m_pHookHelper.ActiveView<BR>        Dim pMap As IMap<BR>        pMap = pActiveView.FocusMap<BR>        Dim pMxdC As IMxdContents<BR>        pMxdC = pMap<BR>        Dim pMapDocument As New MapDocumentClass<BR>        Dim pSaveFileDialog As New SaveFileDialog<BR>        pSaveFileDialog.Title = "保存为文件"<BR>        pSaveFileDialog.Filter = "文件类型 (*.mxd)|*.mxd"<BR>        pSaveFileDialog.FileName = pMapControl.DocumentFilename<BR>        pSaveFileDialog.ShowDialog()</P>
<P>        'Exit if no map document is selected<BR>        Dim sFilePath As String<BR>        sFilePath = pSaveFileDialog.FileName<BR>        If sFilePath = "" Then Exit Sub<BR>        pMapDocument.[New](sFilePath)<BR>        pMapDocument.ReplaceContents(pMxdC)<BR>        pMapDocument.Save(True, True)<BR>    End Sub</P>

大家帮忙顶顶啊!!

同样你也可以用SxDocument CoClass来控制3d 文档啊

<P>非常谢谢总统先生,总算有人关系小弟了!</P>
<P>Available with ArcGIS Desktop,在ArcEngine中用不了?</P>

哪里出问题了,大侠指明道路啊?????
