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. Others situations may vary, and your advice i
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 As http://www.developerfusion.com/code/4325/on-error-resume-next-considered-harmful/ any seasoned VB programmer knows, the On Error Resume Next statement is http://www.vbforums.com/showthread.php?448401-Classic-VB-What-is-wrong-with-using-quot-On-Error-Resume-Next-quot 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()

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 error on error resume 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:-).

If it is used properly, "On Error Resume Next" is a valid method of dealing with errors - but it is a method that needs to be used appropriately for the situation. While using it means that you don't get any 'annoying' error messages that stop your program, it can easily cause much bigger problems than that, such as: If one error happens, then the code after that point is likely to have errors too (especially if the first error occurred while doing something like setting the value of a variable). The follow-up error(s) that occur may be simple and 'safe', such as getting the wrong result displayed on screen (but not knowing it is wrong)... or they could be much more serious, such as accidentally deleting an important file, because you had an error getting the name of the file that you wanted to delete. If you have made any coding mistakes (such as putting a text value into an Integer variable) then your code wont do what it is supposed to do, and you wont know why. Not only is the problem hidden from you, but so is the location of it. If you are running within VB, you would normally get the line highlighted - but with "On Error
