Visual Basic for Applications Reference Visual Studio 6.0 On Error Statement See Also Example Specifics https://msdn.microsoft.com/en-us/library/aa266173(v=vs.60).aspx Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred where execution continues. Use this form rather than On Error GoTo when accessing objects. On Error GoTo 0 Disables any enabled error handler in the current procedure. Remarks If you don't use an On Error statement, any run-time error that occurs is fatal; that is, an error message is displayed and execution stops. An "enabled" error handler is one that is turned on by an On Error statement; an "acti

This statement turns the error handler off and would mean that any error would crash the app. Why would this 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 on error goto 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 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

Sub Method() On Error Goto ErrorHandler ... CleanUp: ... Exit Function ErrorHandler: Log error etc Err.Clear 'Is this line actually necessary?' Resume CleanUp 'SHOULD USE THIS' Goto CleanUp 'SHOULD NOT USE THIS' End Sub My question is what difference is there in the execution of the two? vb6 error-handling share|improve this question asked Jun 8 '10 at 11:01 Richard Oliver 30229 add a comment| 2 Answers 2 active oldest votes up vote 20 down vote accepted Both transfer execution to the Cleanup label. As far as I can remember, the only differences are Using Goto doesn't clear the Err object (so Err.Clear is necessary if you use Goto) and it leaves your error handler disabled. If an error occurs after the Cleanup label, it won't be handled at ErrorHandler. Using Resume clears the Err object and it switches your error handler back on (it is disabled while it is handling errors). If an error occurs after the Cleanup lable, it will be handled at ErroHandler The VB6 manual entry for the Resume statement doesn't explain these differences. share|improve this answer answered Jun 8 '10 at 11:09 MarkJ 24.9k34878 Cheers MarkJ, learn't alot from this answer. –Richard Oliver Jun 8 '10 at 11:19 1 While testing i've found that if an error is raised in CleanUp an infinte loop will exist bouncing between the ErrorHandler and CleanUp blocks. Is the recommended technique therefore to have On Error Resume Next in the CleanUp? –Richard Oliver Jun 8 '10 at 13:55 @Rich Oliver Yes, that's what I do.
