Join them; it only takes a minute: Sign up Why would you ever use “On vb6 runtime error -2147467259 Error Goto 0”? up vote 19 down vote favorite 5 Why would you ever use "On Error Goto 0" in a VB6 app? This statement turns the error handler off and would mean that any error would crash the app. Why would this https://msdn.microsoft.com/en-us/library/5hsw66as.aspx ever be desirable? vb6 error-handling share|improve this question asked Apr 2 '12 at 20:37 CJ7 4,99232114220 4 Well, it's certainly a way of implementing fail-fast –Greg Hewgill Apr 2 '12 at 20:39 I don't have VB6 installed, but presumably any Goto statement to a non-existant label would crash the app. –Sam Axe Apr 2 '12 at 20:40 This sounds like a comment from somebody who either throws in On Error Resume Next at the head of each procedure and then has mysterious woes http://stackoverflow.com/questions/9983464/why-would-you-ever-use-on-error-goto-0 that can't be diagnosed, or one who puts in On Error GoTo MyHandler and there just pops up a MsgBox with the same error anyway. –Bob77 Apr 2 '12 at 21:14 2 Not true at all. It is commonly paired with On Error Resume Next and a test of Err.Number to do inline structured error handling. –Bob77 Apr 3 '12 at 0:52 1 @CraigJ: Remember that the error handling is for that procedure (and children) only. "Turning it off" is NOT global, and allows errors to be handled by the parent. –Deanna Apr 3 '12 at 15:28 | show 9 more comments 4 Answers 4 active oldest votes up vote 35 down vote In VB6, you can specify that you want errors to be handled by particular code later in the routine: Sub Bar() On Error Goto MyHandler ... ...some code that throws an error... ... Exit Sub MyHandler: ...some error handler code (maybe pops up a dialog) End Sub It may be the case, however, that the code that throws the error is localized, and you don't want that same handler for all of the rest of the code in the routine. In that case, you'd use "On Error Goto 0" as follows: Sub Bar() ... On Error Goto MyHandler ...some code that throws an error... On Error Goto 0 ... ... Exit Sub MyHandler: ...some error handler code (maybe pops up a dialog) End Sub Now you have effectively scoped the error handling to execute only if that particular line of code fails.

RE: On Local Error vs On Error jebenson on error goto (TechnicalUser) 18 May 05 10:11 There is no functional difference between On Error and On Local Error.The latter is a deprecated holdover from earlier versions of VB to ease upgrading code written in those earlier versions.In VB6, the Local keyword is ignored.
