ACC: Cannot Trap ODBC Errors with Form OnError Property Code

ID: Q124395

The information in this article applies to:

SYMPTOMS

Advanced: Requires expert coding, interoperability, and multiuser skills.

Even though you have specified event procedure code to trap errors in your form's OnError property, you still receive ODBC error messages.


CAUSE

ODBC error messages normally occur in two parts. The first part is

ODBC call failed

followed by a second part such as:
[Microsoft][ODBC SQL Server Driver][SQL Server] <Server-specific error message>

The first part of the error message can be trapped by the code specified in the OnError property, but the second part cannot. The second part of the error message appears on the screen after the event procedure code finishes running.


RESOLUTION

If the ODBC error is triggered by a procedure that contains a routine to handle errors (rather than by a form), the procedure will be able to trap both parts of the error message.


STATUS

Microsoft has confirmed this to be a problem in Microsoft Access 2.0 and 7.0. This behavior has been changed in Microsoft Access 97.

NOTE: Although this behavior has changed in Microsoft Access 97, you can still not trap the second part of the error. An event does fire when there[ASCII 146]s an error; however, there is no retrievable information about the error message. The event that fires only helps you to hide existing errors from a user.
