Help! I have a Access 2003 Database that holds info like "customer name" "phone number" etc. When I enter that info and then click new record then go back to the previously created record and add some more information in the other text boxes ("address", "age", etc) I get the following error:
Concurrency violation: the UpdateCommand affected 0 of the expected 1 records
and when I click on details then row, I get this:
'((Help_Desk_Center.HDC_DataDataSet.Table1Row)(((System.Data.DBConcurrencyException)($exception)).Row)).Customer_called_on' threw an exception of type 'System.Data.StrongTypingException'
What is all that and how do I fix it, get around it, ignore it, or what ever I need to do?? Thanks for the help
Hi,
It's probably because you have not entered values for fields that are not nullable. Can you post more information?
