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.
Error Number : -2147217900 Vba
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 error handler becomes ac

Error Trapping Office 2007 Access Developer Reference You can use the 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 https://msdn.microsoft.com/en-us/library/bb256427(v=office.12).aspx 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. Notes In versions 1.x and 2.0 of Microsoft Access, you might have used the Error statement to generate the error, the Err function to return the error number, and the Error function to return a description of the error. Existing error-handling code that relies on the Error statement and the Error function will continue to work. However, it's better to use the Err obj

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 vba error handling 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 2,3361725 asked Dec 10 '08 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
