Error Trapping [Access 2003 VBA Language Reference] Office 2003 You can use the vba code access 2003 On Error GoTo statement to trap errors and direct procedure flow to the location of error-handling statements within a procedure. For example, the following statement directs the flow to the ErrorHandler: label line: On Error GoTo ErrorHandler Be sure to give each error handler label in a procedure a unique name that will not conflict with any other element in the procedure, and make sure you append a colon to the name. Within the procedure, place the Exit Sub or Exit Function statement in front of the error handler label so that the procedure doesn't run the error-checking code if no error occurs. Sub CausesAnError() ' Direct procedure flow. On Error GoTo ErrorHandler ' Raise division by zero error. Err.Raise 11 Exit Sub ErrorHandler: ' Display error information. MsgBox "Error number " & Err.Number & ": " & Err.Description ' Resume with statement following occurrence of error. Resume Next End Sub The Raise method of the Err object generates the specified error. The Number property of the Err object returns the number corresponding to the most recent run-time error; the Description property returns the corresponding message text for a given error.

quit the procedure. Each procedure, then, will have this format (without the line numbers): 1 Sub|Function office 2003 vba SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label to resume excel 2003 vba macros after error. 5 Exit Sub|Function ' Exit before error handler. 6 Err_SomeName: ' Label to jump to on error. 7 MsgBox Err.Number & Err.Description ' Place error handling here. 8 Resume Exit_SomeName ' Pick up again and quit. https://msdn.microsoft.com/en-us/library/office/aa172275(v=office.11).aspx 9 End Sub|Function For a task where several things could go wrong, lines 7~8 will be replaced with more detail: Select Case Err.Number Case 9999 ' Whatever number you anticipate. Resume Next ' Use this to just ignore the line. Case 999 Resume Exit_SomeName ' Use this to give up on the proc. Case Else ' Any unexpected error. Call LogError(Err.Number, Err.Description, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom http://allenbrowne.com/ser-23a.html function to write the error details to a table. This allows you to review the details after the error has been cleared. The table might be named "tLogError" and consist of: Field Name Data Type Description ErrorLogID AutoNumber Primary Key. ErrNumber Number Long Integer. The Access-generated error number. ErrDescription Text Size=255. The Access-generated error message. ErrDate Date/Time System Date and Time of error. Default: =Now() CallingProc Text Name of procedure that called LogError() UserName Text Name of User. ShowUser Yes/No Whether error data was displayed in MsgBox Parameters Text 255. Optional. Any parameters you wish to record. Below is a procedure for writing to this table. It optionally allows recording the value of any variables/parameters at the time the error occurred. You can also opt to suppress the display of information about the error. Function LogError(ByVal lngErrNumber As Long, ByVal strErrDescription As String, _ strCallingProc As String, Optional vParameters, Optional bShowUser As Boolean = True) As Boolean On Error GoTo Err_LogError ' Purpose: Generic error handler. ' Logs errors to table "tLogError". ' Arguments: lngErrNumber - value of Err.Number ' strErrDescription - value of Err.Description ' strCallingProc - name of sub|function that generated the error. ' vParameters - optional string: List of parameters to record. ' bShowUser - optional boolean: If False, suppresses display.

See solution in other versions of Access: Access 2007 Access 2003 Question: In Microsoft Access 2003/XP/2000/97, 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 access 2003 vba 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 = 3146 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.
