I've tried google and msdn, but I've had no luck. excel vba msdn share|improve this question asked Jan 4 '13 at 14:22 sterlingalston 155116 This documentation is for Visual Basic, not VBA, but the concepts are similar enough in this case that it should explain the difference. –vcsjones Jan 4 '13 at 14:30 add a comment| 4 Answers 4 active oldest votes up vote 33 down vote accepted On Error GoTo 0 disables any error trapping currently present in the procedure. On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled. Sub OnErrorGotoZeroTest() On Error GoTo 0 Err.Raise Number:=9999, Description:="Forced Error" End Sub share|improve this answer edited Mar 22 '13 at 10:08 answered Jan 4 '13 at 15:29 Francis Dean 1,42611118 1 +1, good explanation. It is interesting to point out that ONLY On Error Goto -1 will allow further error trapping within error trapping. Infact, even On Error Resume Next will still result in an untrapped error that halts operation. –Daniel Jan 4 '13 at 15:32 Thank you both so much, @Francis Dean and Daniel Cook. I've ended up using this in my code a long time ago, but never knew why I could get it to work after Goto -1.

Any number of run-time errors can occur, and if your program does not trap them, the VB default action is to report the error and then terminate the program (often resulting in the end user calling you and complaining, "Your program kicked me out!"). By placing error-handling code in your program, you can trap a http://stackoverflow.com/questions/14158901/difference-between-on-error-goto-0-and-on-error-goto-1-vba run-time error, report it, and let the user continue. Sometimes the user will be able to correct the error and sometimes not, but simply allowing the program to crash is not acceptable. You should generally place error-handling code in any Sub or Function that accesses files or databases. Your code will typically interrogate the Number and Description properties of http://www.vb6.us/tutorials/error-handling-visual-basic the built-in VB Err object in an error-handling routine set up with the On Error statement. In this section, we will look at the following statements: On Error GoTo label On Error Resume Next Following is a brief tutorial in error-handling. To perform this tutorial, you should have a floppy disk handy. Also, in the VB IDE, make sure that the Break on Unhandled Errors option is set under Tools à Options à General. STEPS: 1. Start a new project. 2. Place four command buttons on the form. Name them and set their Captions as follows: Name Caption cmdCrash Crash cmdGoToLabel GoTo Label cmdGoTo0 GoTo 0 cmdResumeNext Resume Next Your form should look something like this: 3. Code the cmdCrash_Click event as follows: Private Sub cmdCrash_Click() Open "A:\JUNK.TXT" For Input As #1 MsgBox "File was opened successfully" Close #1 End Sub 4.

I frequently see this statement; however, I don't know what it does. Other times I see "On Error GoTo ErrLine" which I can follow. Can someone tell me where is the "0" or where does the statement take me? Thanks.

That is the exact opposite of what I need to do. If an "INSERT" statement fails, I would like to display a message box showing certain field values to help the user figure out what parameter table entry is wrong. Here is a sample statement that I think is the usual culprit: HTML Code: dbAR.Execute "INSERT INTO Distribution(" & dFlds & ") VALUES(" & _ arRS!ID & ",'" & rs!ref & "'," & pRs!memberID & ",'" & _ d & "',#" & d & "#,0,'Payment-'" & pRs!pmtDesc & "',6," & _ rs!amt & ",0," & rcd & ",'" & dpt & "'," & comp & ")", _ dbFailOnError dbAR.Execute "INSERT INTO Transaction(" & tFlds & ") VALUES('
