本例演示的是如何将shape文件转化成personal GeoDatabase文件，其它格式间的与此转换类似。主要用到IFeatureDataConverter接口的ConvertFeatureClass方法。
要点
首先，创建新的GeoDataBase数据库，并创建IFeatureDatasetName对象。创建定义两个IFeatureClassName接口对象分别引用输入表（shape文件）和输出表。
然后设置输出表的Shape字段的GeormetryDef属性。这一步非常关键，因为其中包含了数据库和shape文件的空间参考信息。
最后调用IFeatureDataConverter.ConvertFeatureClass方法完成功能。
程序说明
过程UIBConvert_Click是实现模块，调用过程ConvertShapeToGeodatabase实现功能。
sDataPath定义了数据与工程文件的相对路径。SHAPE_NAME描述了要转化的shape文件的文件名。MDB_NAME和F_DS_NAME分别描述了Access数据库名和库的数据集的名称。
