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saveAS,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 = "另存为文件"<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>

<P>大家怎么不帮忙顶啊!</P>
