Join them; it only takes a minute: Sign up Err.Number vs try-catch in VB.net up vote 4 down vote favorite I have inherited an old VB.net-project. The code mostly uses try-catch for error-handling. However how to in some places I have found If Err.Number <> 0 Then. If an error occurs, what decides if an Exception should be thrown, or just setting Err? I don't want to handle error both ways... vb.net exception-handling try-catch share|improve this question edited Feb 23 '11 at 17:09 Fredrik Mörk 110k16207284 asked Feb 23 '11 at 17:03 leiflundgren 1,30522147 2 The infamous On Error Resume Next. –Hans Passant Feb 23 '11 at 17:16 add a how to get comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The Err object is use with the old-style On Error error handling construct, that is a remainder from classic VB. Try-Catch is the more current .NET style of error handling. You can learn more about this, and the difference in Error Handling in Visual Basic.NET. share|improve this answer edited Feb 23 '11 at 17:13 answered Feb 23 '11 at 17:05 Fredrik Mörk 110k16207284 How do I decide which error handling is active? Just On Error Goto 0 should set old-style, I think. –leiflundgren Feb 23 '11 at 17:05 @leiflundgren: whatever construct is closest to the code you are looking at will be the active one. You can mix both styles, but not within a method. So you can have one method setting up error handling with an On Error statement, and then call another method that uses Try-Catch. –Fredrik Mörk Feb 23 '11 at 17:07 @fredrik-mork: Ah So if I write On Error Goto 0 (or similar) in a method, I use that stile. Otherwise it's try-catch? –leiflundgren Feb 23 '11 at 17:09 @leiflundgren: yes, almost correct. In order to use Try-Catch you will of course need to include such statements in your code. If you have neither On Error nor Try-Catch, any exce

Handler: System.Console.WriteLine("Error number {0} occurred: {1}", _ Err.Number, Err.Description) End Sub End Module Here's what you see when you run this console application: Error number 6 occurred: Exception of type System.OverflowException was thrown. Tip You can determine the object that caused the exception using the Visual Basic Err object's Source property. This property holds the name of the object or application that caused the exception. For example, if you connect to Microsoft Excel and it generates an exception, Excel sets Err.Number to its error code for that exception, and it sets Err.Source to "Excel.Application".
