a full version of Access, while a run-time version just crashes. For a more detailed approach to error handling, see FMS' article on Error Handling and Debugging. The simplest approach is to display the Access error message error.number vba and quit the procedure. Each procedure, then, will have this format (without the line numbers): access vba error handling module 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label ms access on error resume next 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 ' Place error handling here. 8 Resume Exit_SomeName ' Pick up https://msdn.microsoft.com/en-us/library/5hsw66as.aspx 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 unexpected error. Call LogError(Err.Number, Err.Description, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example http://allenbrowne.com/ser-23a.html 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 of sub|function that generated the error. ' vParameters - optional string: List of parameters to record. ' bShowUser - optional boolean: If False, suppresses display. ' Author: Allen Browne, allen@allenbrowne.com Di

Did you find a solution? What is it? I just realized how many hundreds of hours I spared since I found the right answer to this basic problem a few years ago, and I'd like to see what are your ideas and solutions on this very important issue. vba ms-access error-handling access-vba share|improve this question edited May 27 '15 at 7:40 shruti1810 2,3311725 asked Dec 10 '08 vba error handling at 22:24 Philippe Grondier 7,92721753 add a comment| 4 Answers 4 active oldest votes up vote 5 down vote Well there are a couple of tools that will do what you ask MZ Tools and FMS Inc come to mind. Basically they involve adding an: On Error GoTo ErrorHandler to the top of each proc and at the end they put an: ErrorHandler: Call MyErrorhandler Err.Number, Err.Description, Err.LineNumber label with usually a call to a global error handler where you can display and log custom error messages share|improve this answer answered Dec 10 '08 at 22:40 DJ. 12.7k22941 You took the words out of my mouth! –Philippe Grondier Dec 10 '08 at 23:00 3 This is slightly misleading as Err.LineNumber doesn't exist.. So while good practice for generic error handling, it doesn't answer the crux of the original issue about line numbering. If you need to do this then the answer involving Erl would be better if you had to have a line number. –FinancialRadDeveloper Nov 5 '10 at 12:07 add a comment| up vote 5 down vote What about using "Erl", it will display the last label before the error (e.g., 10, 20, or 30)? Private Sub mySUB() On Error GoTo Err_mySUB 10: Dim stDocName As String Dim stLinkCriteria As String 20: stDocName = "MyDoc" 30: DoCmd.openform stDocName, acFormDS, , stLinkCriteria Exit_mySUB: Exit Sub Err_mySUB: MsgBox Err.Number & ": " & Err.Description & " (" & Erl
