CRecordset Update() error

Dear Friends:

I'm kind of new to database programming. I have some problem
excuting Update() function. during the Update() process, I do have
error message "Invalid descriptor Index".

I can not figure it out what causes that error and how to solve it.
Please HELP!!!

Thanks

Update completes either an AddNew or an Edit function.

Are you sure you called either AddNew or Edit before calling Update?

Hope this helps,

- Nigel

Dear NigelQ:

Thanks for your reponse.
I solved the problems. It was a wrong m_nFields property binded fields.
Again, Thanks for your reply...
