this format (without the line numbers): 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code error handling in access 2013 to do something here. 4 Exit_SomeName: ' Label to resume 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 ' https://msdn.microsoft.com/en-us/library/ee358847(v=office.12).aspx Place error handling here. 8 Resume Exit_SomeName ' Pick up again and quit. 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 http://allenbrowne.com/ser-23a.html unexpected error. Call LogError(Err.Number, Err.Description, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom 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
user may be left viewing the faulty code in a full version of Access, while a run-time version just crashes. The simplest approach is to display the Access error message and quit the procedure. Each http://allenbrowne.com/ser-23b.html procedure, then, will have this format (without the line numbers): 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label to resume after https://www.youtube.com/watch?v=6UIypRy1iE8 error. 5 Exit Sub|Function ' Exit before error handler. 6 Err_SomeName: ' Label to jump to on error. 7 MsgBox Err & " " & Error$ ' Place error handling here. 8 Resume Exit_SomeName ' error handling Pick up again and quit. 9 End Sub|Function The labels (lines 4 and 6) must be in the current procedure, and must be unique. For a task where several things could go wrong, replace lines 7~8 with more detail: Select Case Err Case 9999 ' Whatever number you anticipate. Resume Next ' Use this to just ignore the line. Resume Exit_SomeName ' Use this to give up on the proc. Case vba error handling Else ' Any unexpected error. Call LogError(Err, Error$, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom procedure 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 Integer. The Access-generated error number.

Default: =Now() CallingProc Text Name of procedure that called LogError() UserName Text Name of User. Below is the procedure for writing to this table. If you wish to go further, you could extend it to count errors recorded recently and suppress the display of the same message repeatedly, or give up retrying locking errors. Sub LogError (ByVal iErrNumber As Integer, ByVal strErrDescription As String, strCallingProc As String) On Error GoTo Err_LogError ' Purpose: Generic error handler. ' Logs errors to table "tLogError". ' Arguments: iErrNumber - value of Err ' strErrDescription - value of Error$ ' strCallingProc - name of sub|function that generated the error.
