I saw the recent support of Personal Geodatabases, and have utilized that in my application. I'd also like to use a File Geodatabase (which, to my knowlege, is very similar to the Personal Geodatabase, except it stores the data in separate files, rather than one mdb file). The differences between the Personal and File Geodatabases can be seen at this page: webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Types_of_geodatabases
In essence, structure is the same, I just need a class to instantiate that will form the FeatureLayer using the geodatabase directory instead of a single mdb file. I know this is FDO stuff, so if anyone can point me in the right direction I'd really appreciate it!
