Error Trapping [Access 2003 VBA Language Reference] Office 2003 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 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 ob

Resume Next ' Use this to just ignore the line. Case 999 Resume Exit_SomeName ' Use this to give up on the proc. Case Else ' http://allenbrowne.com/ser-23a.html 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 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 ' strCallingP

But the process doesn't have to be that difficult. Most of us need only a simple function to log specific information about the current error.

Most developers include adequate error-handling routines in their code, but that might not be enough. Knowing when an error occurs and how often it occurs can be important to resolving the issue and avoiding future errors. Access doesn't track errors, but you can add that functionality to any database. All you need is a table and a little code. Note: Our companion download includes a demonstration database and a several .bas module files you can import into any Access database. Don't cut and paste the code directly from here into an Access module, as the article text contains formatting that will generate errors. The easiest way If you have just one database to maintain and you're its only user, error logging isn't a critical issue because you're around when the error occurs. However, it's difficult to display internal error information at the time of the error. It isn't impossible, but even if your application displays it, you have to r

Is there any way to de-activate the first error handler after it has been used? Set objexcel = CreateObject("excel.Application") objexcel.Visible = True On Error GoTo Openwb wbExists = False Set wbexcel = objexcel.Workbooks.Open("C:\REPORT3.xls") Set objSht = wbexcel.Worksheets("Sheet1") objSht.Activate wbExists = True Openwb: On Error GoTo 0 If Not wbExists Then objexcel.Workbooks.Add Set wbexcel = objexcel.ActiveWorkbook Set objSht = wbexcel.Worksheets("Sheet1") End If On Error GoTo 0 Set db = DBEngine.opendatabase("C:\book.mdb") Set rs = db.OpenRecordset("records") Set rs2 = CreateObject("ADODB.Recordset") rs2.ActiveConnection = CurrentProject.Connection For Each tdf In CurrentDb.TableDefs If Left(tdf.Name, 4) <> "MSys" Then rs.MoveFirst strsql = "SELECT * From [" & tdf.Name & "] WHERE s=15 " Do While Not rs.EOF On Error Resume Next rs2.Open strsql Upon execution of the last statement I want to ignore the error and move on to the next table but error handling does not seem to work. ms-access share|improve this question edited Mar 2 at 15:25 Brian Leeming 5,35431639 asked Dec 1 '08 at 14:06 tksy 1,006123956 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted It is nearly always better to avoid errors, rather than handling them. For example: Set objexcel = CreateObject("excel.Application") objexcel.Visible = True 'On Error GoTo Openwb ' 'wbExists = False ' If Dir("C:\REPORT3.xls") = "" Then objexcel.Workbooks.Add Set wbexcel = objexcel.ActiveWorkbook Set objSht = wbexcel.Worksheets("Sheet1") Else Set wbexcel = objexcel.Workbooks.Open("C:\REPORT3.xls") Set
