有关装入access数据库的入门级问题求助！在线等待

<P>各们大侠：</P>
<P>本人初学vc+ao+ae编程，现想装入一个access数据库的内容到mapcontrol中，可总是出现一个指针错误，不知原因是什么，请各位帮忙！代码如下：</P>
<P>CComBSTR connString=CComBSTR("f:\\gis\\空间分析<a>\\arcgis</A>");<BR>IWorkspaceFactoryPtr ipWsFactory(CLSID_AccessWorkspaceFactory);<BR>IFeatureWorkspacePtr ipFWspace;<BR>IWorkspacePtr ipws;<BR>IFeatureClassPtr ipFClass;<BR>IFeatureLayerPtr ipFLayer;<BR>IFeatureDatasetPtr ipFDataset;<BR>ipWsFactory->OpenFromFile(connString,NULL,;ipws);<BR>ipFWspace=ipws;</P>
<P>ipFWspace->OpenFeatureDataset(CComBSTR("paper"),;ipFDataset);<BR>IFeatureClassContainerPtr ipFCC;<BR>ipFCC=ipFDataset;</P>
<P>就是执行到ipFWspace->OpenFeatureDataset......这句时出错！</P>
<P>谢谢哈！</P>

数据库路径为f:\gis\空间分析\arcgis\paper.mdb
