How to: Handle Run-Time Errors in VBA Office 2007 Access Developer Reference 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 error handler is to enable an error handler by including some form of the On Error statement within the procedure. The On Error statement directs execution in event of an error. If there is no On Error statement, Visual Basic simply halts execution and displays an error message when an error occurs. When an error occurs in a procedure with an enabled error handler, Visual Basic does not display the normal error message. Instead it routes execution to an error handler, if one exists. When execution passes to an enabled error handler, that erro

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.

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 '08 at 22:24 vba error handling 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)?

Note: The OnError macro action isn't available in Access web apps. Setting The OnError macro action has the following arguments. Action argument Description Go to Specify the general behavior that should occur when an error is encountered. Click the drop-down arrow and then click one of the following settings: Setting Description Next Access records the details of the error in the MacroError object but does not stop the macro. The macro continues with the next action. Macro Name Access stops the current macro and runs the macro that is named in the Macro Name argument. Fail Access stops the current macro and displays an error message. Macro Name If the Go to argument is set to Macro Name, type the name of the submacro to be used for error handling. The name you type must match a submacro name in the current macro; you can't enter the name of a different macro object. In the example below, the ErrorHandler sub macro is contained in the same macro object as the OnError macro action. This argument must be left blank if the Go to argument is set to Next or Fail. Note: The macro design window was changed in Access 2010. If you are using Access 2007, the name of the macro to be used for error handling must match a name in the Macro Name column of the current macro. Remarks The OnError macro actio
