Inserting data to Access DB ?

Question

I have problem with DB access to MSAccess in a web application. The problem is that reading data from DB works just fine, but inserting and updating causes exception: Server Error in '/myApp' Application. -------------------------------------------------------------------------------- Operation must use an updateable query. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.OleDb.OleDbException: Operation must use an updateable query The same DB access works fine with a windows application. Thus it might be a security issue. But what should be done in order to give the web application the right to make insert into Access DB ? -Ari
