There are certain limitations to using the commandbuilder class. Command Builder cannot auto generate statements for select commands that access multiple tables. This is a limitation of the CommandBuilder class in .NET and has nothing to do with the VFP provider. If you are attempting to use the commandbuilder with multiple tables you might want to keep that in mind. If this is not the case, I will be more than happy to send you some code which demonstrates autogeneration of IUD statements.
