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 decision
of the vb.net world, I use the Try/Catch statement quite a bit for when it comes to errors, as the following. With Me .Text = "a" Try https://www.daniweb.com/programming/software-development/threads/423676/try-catch-vs-on-error-resume-next .Text += 1 Catch ex As Exception MsgBox("error: " & ex.Message, MsgBoxStyle.Critical) http://www.java-samples.com/showtutorial.php?tutorialid=1275 End Try MsgBox("a") .Text = "b" Try .Text += 1 Catch ex As Exception MsgBox("error: " & ex.Message, MsgBoxStyle.Critical) End Try MsgBox("b") End With For the first time today, I attempted to use the On Error Resume Next and it returned the results I needed; less lines of code and on error only results if an error occured. On Error Resume Next With Me .Text = "a" .Text += 1 MsgBox("a") .Text = "b" .Text += 1 MsgBox("b") End With My question is, even though quite clear to me: For such lines of code as above, is the On Error Resume Next appropriate and can I move on to the next part of my.app on error goto with no worries, ever?.thanx.in.adv,.Me. error vb.net â””(vb.net: codeorder.net)â”â””(DaniWeb: How to mark a thread as solved?)â”â””(.reality.: .Me ='s Life; .My ='s Univers.e/.al:.bytes.)â” codeorder 197 2,027 posts since Aug 2010 Community Member 3Contributors 6Replies 12Views 4 YearsDiscussion Span 4 Years Ago Last Post by codeorder 0 Oxiegen 88 4 Years Ago By using a Try...Catch statement you can catch the error and do something about it. It's a very useful debugging tool. However, you don't have to enclose every single piece of altering code in it's own statement. You can start the Try statement even before the line With Me and end it below the line End With, followed by the Catch statement with a messagebox displaying the error. With On Error Resume Next, you won't know if an error occured and on what line. So you have no way of knowing and thus can't do much about it. Also. Personally I feel that those types of error catching methods are depricated as they originate from the old-school VB type programming. The Try...Catch statement is the .NET way. That includes the use of MsgBox. Have you lo

You can use Resume to resume execution with the statement that caused the exception, Resume Next to resume execution with the statement after the one that caused the exception, and Resume line, where line is a line number or label that specifies where to resume execution. Here's an example using Resume Next, which lets you skip over the line that caused the problem: Module Module1 Sub Main() Dim int1 = 0, int2 = 1, int3 As Integer On Error Goto Handler int3 = int2 / int1 System.Console.WriteLine("Program completed...") Exit Sub Handler: If (TypeOf Err.GetException() Is OverflowException) Then System.Console.WriteLine("Overflow error!") Resume Next End If End Sub End Module Here's what you see when you run this console application: Overflow error! Program completed... And here's an example using the Resume line form: Module Module1 Sub Main() Dim int1 = 0, int2 = 1, int3 As Integer On Error Goto Handler int3 = int2 / int1 Nextline: System.Console.WriteLine("Program completed...") Exit Sub Handler: If (TypeOf Err.GetException() Is OverflowException) Then System.Console.WriteLine("Overflow error!") Resume Nextline End If End Sub End Module You can also use an On Error Resume Next or On Error Resume line statement to make
