[讨论]vs2005 vc++(com接口)中打不开shapefile的workspace,不知道是什么问题,在好几台机子上都一样

mFLSName = FLSName;
mWorkspaceDir = WorkspaceDir;
BSTR dir = mWorkspaceDir.AllocSysString();

IWorkspaceFactoryPtr pWSF(CLSID_ShapefileWorkspaceFactory);//用于读取FeatureClass的workspacefactory
//IWorkspacePtr pWS;
pWSF->OpenFromFile(dir,0,;(mpWS.GetInterfacePtr()));(这里运行过去后,mpWS指针还是指的空值,不知道出什么错了,SDK自带的例子也运行不起来)
