请教：如何保存一个SxD文件

<BR>那位知道如何实现保存SXD 文档，用编程打开SXD很容易，但没有保存的功能。

<P>可以利用IPersistStream接口来保存，可以先看看帮助，具体问题可以到这里讨论</P>IPersistStream Interface (esriSystem)
<br>
<p>
<p>
<P>Product Availability</P>Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
<P>Description</P>
<P>IPersistStream is a Microsoft interface. Please refer to MSDN for information about this interface.</P>

不知怎么去做，怎么能保存？

<PRE>*******code from Esri*************
Dim pMemoryBlobStream As IMemoryBlobStream
Set pMemoryBlobStream = New MemoryBlobStream
Dim pObjectStream As IObjectStream
Set pObjectStream = New ObjectStream
Set pObjectStream.Stream = pMemoryBlobStream

Dim pPersistStream As IPersistStream
Dim pPageLy as iPageLayout
 Set pPageLy = pMxDoc.PageLayout
Set pPersistStream = pPageLy
'page layout implements ipersiststream only

pPersistStream.Save pObjectStream, False
pMemoryBlobStream.SaveToFile “C:\Temp\MyFile.blb”
'ipagelayout object is saved to a file

'**now I could also retrieve the object from the file
like this ***'
dim pPageLy1 as iPageLayout
set pPageLy1 = new PageLayout

Dim pObjectStream As IObjectStream
Set pObjectStream = New ObjectStream

Dim pMemoryBlobStream As IMemoryBlobStream
Set pMemoryBlobStream = New MemoryBlobStream
pMemoryBlobStream.LoadFromFile “C:\Temp\MyFile.blb”

Dim pPersistStream As IPersistStream
Set pPersistStream = pPageLy1
Set pObjectStream.Stream = pMemoryBlobStream
pPersistStream.Load pObjectStream
'this would create new page layout object</PRE>

不错啊，果然可以，而且效果和ArcScene里的文档一样，只是直接用Arcscene打不开，呵呵，实现了，真好。

不错,好

请楼主把打开SXD 文档的代码写出来,让我参考一下吧!

代码写出来吧
