Access 2000 Error Handling

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 and quit sql 2000 error handling the procedure. Each procedure, then, will have this format (without the line numbers): 1 Sub|Function sql server 2000 error handling SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label to resume access error handling query 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.

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 function error handling in access vba 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.

Errors and Error Handling When you are programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. When adding error handling to a procedure, you should consider how the procedure will route execution when an error occurs. The first step in routing execution to an err

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 2,3231725 asked Dec 10 2000 error handling '08 at 22:24 Philippe Grondier 7,90721753 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. 12.6k22941 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 & " (" &

Advertisment Error Handling (Global) Options Error Handling (Global) This article describes How-To content for a given task Related Content: Error Handling <-- see for more links on handling errors At some point in the journey to learn and master Access, the generation our VBA code will supercede the use of certain wizards. One of those will eventually be the VBA Code Wizard. Although it is a quick method of generating a procedural ‘shell’, it’s auto-generated error handling can be more robust when we more effectively manage any errors that may occur. Writing error handling routines for each and every procedure can be tedious. The code example(s) and demo app of this tutorial can provide a way to trap and manage unexpected errors. But then, what other kind of error is there? (Random, undocumented features, to be sure!) A ‘global’ approach to error handling is the thrust of this discussion, where we will employ ‘global’ variables to assist in the management of the information collected during an error trapping process. We will also explore the primary Error Handling routine(s)/module in detail and how the ‘global’ variables play their part in passing a procedure’s error info to the primary routine. Then, once the primary routine has been given a procedural call and error info, we will be able to present a user with an on-screen message, a text-based error file and/or the ability to email the error to a developer and/or application administrator. Also demonstrated will be how to bring these Global Error Handling routines into your working Access application.
