Visual Basic for Applications Reference Visual Studio 6.0 On Error Statement See Also Example Specifics Enables an on error resume next example 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 "active" error handler is an en

Why do you possibly need this? If you explain the motivation behind your thoughts of doing this, I'm sure that someone here could give you a better solution. –Cody Gray Jan 28 '11 at 6:17 @Cody Gray - updated the reason of asking. Thanks –Neel Jan 28 '11 at 6:31 2 @MarkJ: Because even if (s)he leaves the code as VB.NET, it's still a good idea to replace On Error Goto Next with more structured exception handling (or none at all). –Cody Gray Jan 29 '11 at 2:04 4 @Cody It is an improvement to replace the error handling, but you have to assess how long it will take (how much it will cost) and whether the code needs substantial modifications. If the code works & doesn't need changing, there may be better things to do with the time instead. –MarkJ Jan 29 '11 at 14:21 1 @MarkJ: Fair enough. I don't disagree with you, I was just providing what I felt was a convincing argument for the other side. This is one of those design decisions you have to make. Do I stick with sloppy code that happens to work, or do I take the time to improve it for long-term benefits. I was assuming the reason the conversion was being undertaken was because the code didn't work exactly right as-is.
Visual Basic 6 Code "On Error Resume Next" considered harmful By Palo Mraz, published on 21 Jan 2004 | Filed in Comments Visual Basic 6 SQL Server SQL http://www.developerfusion.com/code/4325/on-error-resume-next-considered-harmful/ As any seasoned VB programmer knows, the On Error Resume Next statement is used to check for errors the old (I might also say the C-style) way. When this statement is executed, any runtime error will be silently trapped and stored in the global Err object. We VB-ers typically use this construct to execute some "non-mission critical" code, where errors can be safely ignored. The on error canonical example I have seen many, many times, is the Form_Resize event handling procedure: Private Sub Form_Resize()
On Error Resume Next
' Resize the child controls on this form…
End Sub If this procedure did not contain the On Error Resume Next statement and a runtime error would occur, the application would be terminated with a nasty on error resume error message. (You do catch runtime errors in every event handling procedure, don't you?) In cases like this, the On Error Resume Next statement is quite handy, because it means less typing and more compact code. However, there are times, when this "handiness" might be very dangerous. The true danger of the On Error Resume Next statement lies in the fact that it makes it too easy to ignore the runtime errors. I have seen several cases, when ignoring runtime errors unintentionally was a recipe for disaster. Let me provide you with a real-life example taken from my own experience. Imagine a customer who had been using my application for several months and was happy with it. The application has a typical (somewhat boring:-) three-tier architecture (in the old days known as the Microsoft Windows DNA): VB6 front end; a typical forms-based application built with several 3rd party controls (GridEX, ActiveReports and AddFlow if you must know). VB6 back end; a DLL component configured to run as a COM+ application implementing the application's business logic (there is also the data access code-who writes middle-tier data access layer anyway:-).
