For example: Try line on error 1 line 2 line 3 line 4 ( here the exception is thrown and jumps to the catch) line 5 <-- i would like the program to continue its execution loging the error line 6 Catch ex as Exception log(ex.tostring) End Try Thanks. vb.net exception-handling share|improve this question edited Nov 13 '12 at 12:56 gabsferreira 1,45941848 asked Jul 29 '10 at 20:24 carlos 3832623 add a comment| 8 Answers 8 active oldest votes up vote 8 down vote accepted If on error goto you're doing something that you know how to recover from or that isn't vital, you're supposed to wrap just that line in the try/catch with a specific catch. e.g. Try line 1 line 2 line 3 Try line 4 ( here the exception is throw and jumps to the catch) Catch iox as IOException ' or whatever type is being thrown 'log it End Try line 5 <-- i would like the program to continue its execution after loggin the error line 6 Catch ex as Exception log(ex.tostring) End Try share|improve this answer edited Nov 13 '12 at 13:01 gabsferreira 1,45941848 answered Jul 29 '10 at 20:36 Nikki9696 4,3241618 add a comment| up vote 5 down vote Use 'Continue For' Not good practice everywhere, but useful in some circumstances, e.g. find a file while handling denied access to certain directories: Dim dir As New DirectoryInfo("C:\") Dim strSearch As String = ("boot.ini") For Each SubDir As DirectoryInfo In dir.GetDirectories Try For Each File As FileInfo In SubDir.GetFiles Console.WriteLine("Sub Directory: {0}", SubDir.Name) If File.Name = strSearch Then Console.Write(File.FullName) End If Next Catch ex As Exception Console.WriteLine(ex.Message) Continue For End Try Next share|improve this answer answered Apr 22 '11 at 7:50 Eddie 11114 add a comment| up vote 2 down vote Although On Error Resume Next is still available in VB.NET, it is mutually exclusive to the preferred method of structured exception handling. Instead, I would recommend the use of the Finally clause
