AE编程不认识 arcid　怎么办？

<P>方法一：    </P>
<P>Dim pCmdItem As ICommandItem<BR>    ' Use ArcID module and the Name of the Save command</P>
<P>　 '下面步骤在arcScene环境下通过，但是ＡＥ编程却不认识arcid，请问怎么办<BR>Set pCmdItem = Application.Document.CommandBars.Find(arcid.File_Save)<BR>pCmdItem.Execute</P>
<P>方法二：</P>
<P>  Dim pUID As New UID<BR>  Dim pCmdItem As ICommandItem<BR>  ' Use the GUID of the Save command<BR>  pUID.Value = "{22E301BD-A6B6-11D3-ABB8-0008C73FCA1C}"<BR>  ' or you can use the ProgID<BR>  ' pUID.Value = "esriArcScene.SxFileMenuItem"<BR>  pUID.SubType = 3</P>
<P>  ' 下面步骤在ＡＥ编程提示“对象或with block变量未赋值”，请问怎么解决？？<BR>  Set pCmdItem = Application.Document.CommandBars.Find(pUID)<BR>  pCmdItem.Execute<BR></P>

<P>在AE里没有iApplication和iDocument这样的接口，多看看帮助</P>IApplication Interface (esriFramework)
