>How does COMCodeBook deal with errors such as the following:
>
>I have a web page that ask for a User Record based upon a key.
>The data is brought to the user for modification.
>They think about it for awhile and make their modifications.
>But while they are thinking someone else changed the data.
>Then web user presses the Save button.

>Does COMCodeBook controls just blowup with an OLE DB/ODBC error, does it report back that someone has changed the data, or does it even handle this type of error?
