Trappable Errors in Visual Basic

While the structured exception handling model provided in Visual Basic is more useful in developing applications, you might choose to employ unstructured error handling, particularly when upgrading legacy applications. You can use the On Error Statement (Visual Basic) to trap and respond to specific errors.

Trappable Errors

Trappable errors can occur while an application is running. Some trappable errors can also occur during development or compile time. You can test and respond to trappable errors using the On Error statement and the Err Object (Visual Basic).

The following table lists error codes and their associated messages.
