Be very cautious using it. –Nate http://stackoverflow.com/questions/2202869/what-does-the-on-error-resume-next-statement-do Feb 4 '10 at 20:22 2 It makes more sense now. After some functions that can end up in error. They have a function called checkError after them. –Omar Feb 4 '10 at 20:37 add a comment| 6 Answers 6 active oldest votes up vote 56 down vote accepted It basically tells the program when you encounter an error just continue at the next line. share|improve this answer answered Feb 4 '10 at 20:19 David 2,2601523 add a comment| up vote 24 down vote It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

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.

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 Resume Next" you wont. In fact, you wont even know that there was an error, all you will know is that you have made some kind of mistake somewhere in that routine. If you don’t know what the problem is, or where it is, how will you fix it?What will the users of your program think if it gives them the wrong results? ..or does something nasty by mistake? They wont be
