How to bind a CLongBinary object with an image filed of .mdb database?

[Wenrich]

the database is of .mdb(Access 2000 version) format, and i'm using DAO to access it. CLongBinary object is only created when an image file needs to be inserted to the database or to be retrieved from database, and it is NOT a data member of CDaoRecordSet( i don't have a derived class from that, instead i'm using CDaoRecordSet directly). how can I bind the CLongBinary object with that field without a redefined DoFieldExchange() ( since i didn't derive a new class)? Thanks a lot!
