Hey everyone<BR><BR>I've been tearing my hair out trying to update a database stored on my local C: drive using objAdapter.Update() having already set up the CommandBuilder objects and the relevant SQL statements. The error message I get is "Operation must use updateable query". Error occurs in the code "objAdapter.Update()". Running on WinXP here. If I change the database source to a floppy drive, the code works fine. Must have something to do with folder, file, user and/or connection permissions. Can someone help? Thanks.<BR><BR>E.
