When capturing and handling errors, you probably think of the Err object, which stores information about the current run-time error. If a form or report encounters an error, you'll find the information you need in an event — the object's Error event to be exact. By default, Access handles action errors without any help from you. On occasion, acdataerrcontinue you might find you want a little more control. When that's the case, take matters into your own hands by usurping the object's Error event. About the Error event Both forms and reports sometimes generate action errors, such as trying to delete a record protected by referential integrity or trying to add a new record without filling in required fields. When this happens, Access displays a predefined warning message that's usually adequate. But if you prefer, you can take charge of the event and force it to do the following: Inhibit the internal message Display a custom message Redirect the application's flow Using the Error event A common form error occurs when you try to save a new record without filling in all required fields (required at the table level). Figure A shows how Access handles this error in a simple form based on the Customers table in Northwind (the sample database that comes with Access). Figure A In this case, the default message is sufficient. In fact, most are. So you probably won't use this event to change the message. Generally, you'll use it to redirect the flow, changing what happens after the Error event occurs. The Error event uses the following syntax: Private Sub object_Error(DataErr As Integer, Response As Integer) End Sub where object is the name of the Form or Report object, DataErr

Some of the standard error messages in Microsoft Access are not extremely user friendly, therefore it is wise if you can intercept these error http://www.techrepublic.com/blog/how-do-i/how-do-i-add-custom-error-handling-to-my-access-forms-and-reports/ messages and replace the standard Microsoft Access error message with a custom error message that will be easily understandable by your database application users. If you expect that a common error may be encountered in one of your Microsoft Access forms, then displaying an error message that displays the error and advises the user what is required to fix the problem will ensure that the database is much more user friendly. Here we will deal with how to replace the standard http://www.databasedev.co.uk/custom-error-message.html Microsoft Access message with one that you have created, which will respond to an error that the user makes in a form. This example will deal with ensuring that the user enters information in to a field or fields where the information has been specified as required data. We need to ensure that the event occurs when the users leaves the required field blank. Initially, we need to find out what error event occurs when we leave a required field blank in the form. To do this we need to cause the error to occur to find out the error number so that we can use this later on. We can use a little piece of code in the Error event of the form to find the error number and we will display this using a msgbox. Below shows the event procedure, for the forms Error event, and shows the required code to display the message when the event occurs. Private Sub Form_Error(DataErr As Integer, Response As Integer) Debug.Print "DataErr = "; DataErr End Sub Now, when we try to enter or edit a record in our form, and we leave a required field blank, we will receive the standard Microsoft Access error message, and we will also be shown the error event number in the Immediate Window in the visual basic editor: Attempting to leave a blank field in the Access form that has it's properties set as Required W

See solution in other versions of Access: Access 2007 Access 2003 Question: In Microsoft Access 2007, I have a form that is linked to an Oracle table. When I enter duplicate data, I receive an error message "ODBC - failed... Unique Constraint violated...". Is it possible to define a custom message to how to make replace the system error message whenever the primary key is violated? (ie: duplicate record) Answer: Yes, you can override the system error messages with your own messages. In your case, you want to place code on the Form's On Error event. For example, you could place the following code on the Form's On Error event to trap the primary key violation: Private Sub Form_Error(DataErr As Integer, Response As Integer) If DataErr = 3022 Then MsgBox ("You have violated the primary key.") Response = 0 End If End Sub Now, whenever a user tries to enter a record that violates the primary key, the following error message will appear: Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have read and accepted our Terms of Service and Privacy Policy.

Custom Error Messages Expert 5K+ P: 8,409 ADezii One of the most frequently asked questions here at TheScripts is: Can I replace Standard Access Error Messages with my own? The answer is yes under certain circumstances and it involves the placement of code in a Form's Error() Event and setting a specific Parameter to either 1 of 2 values. Many Errors occur while your Form is active and it is within this context that you can replace the standard Access behavior when these Errors occur with behavior that is a little friendlier to the User. As previously stated, by attaching code to the Error() Event of a Form, your Procedure will be called whenever a Trappable Error occurs while the Form is running. The Syntax for the call is as follows: Sub Form_Error(DataErr As Integer, Response As Integer) __1. DataErr - contains the Error Number for the Error that just occurred. __2. Response - Allows you to specify how you want Access to handle the Error. If your code handles the Error to your satisfaction and you don't want Access to intervene or display its own message, place the value acDataErrContinue in Response. If you want Acces to display its own Error Message, place acDataErrDisplay in Response. The following code traps 4 Errors that might pop up. In each case, the procedure replaces the Standard Access Error Message with its own. If an Error occurs that it hadn't planned on, the Procedure just passes the responsibility back to Access: Expand|Select|Wrap|Line Numbers PrivateSubForm_Error(DataErrAsInteger,ResponseAsInteger) ConstconErrDataValidation=3317 ConstconErrDataType=2113 ConstconErrDuplicateKey=3022 ConstconErrNullKey=3058 SelectCaseDataErr CaseconErrDataValidation,conErrDataType 'yourErrorMessagehere Response=acDataErrContinue Casec
