求AO加载SDE中FeatureDataset的方法？

通过SDE连接，可以获取FeatureDataset
ftrDataset = pWorkspace.OpenFeatureDataset("SDE.FZ_DLG")
请问如何将ftrDataset加载到AO中去？

<P>应该看看帮助就有</P><P>'Create a workspace factory for an <FONT style="BACKGROUND-COLOR: #0a246a" color=#ffffff>sde</FONT> workspace

<P>哎，在下愚笨，看不太明白！</P><P>大虾能讲得稍微清楚一些吗？ </P>
