try-catch stops execution on error

i noticed that implementing a try catch in any code stops the execution when it catches an error. how do we continue the execution?

eg:

VB

Try
            Dim i As Integer = 0
            For i = 0 To RichTextBox2.Lines.Count - 1
                ReturnSynonyms(RichTextBox2.Lines(0))
            Next
        Catch ex As Exception
        End Try

in above code if richtextbox2 has a word like aaa, for which there are no synonyms, the try-catch catches an error and stops, how do i continue searching the whole for loop even there is an exception caught??

If you don't want Try-Catch, why put it in the first place?

you got your answer, but this is a perfect example of why proper use of the Try/Catch is so important. Many, many people just add a Try/Catch to a huge block of code, when it is meant, AFAIK, to target specific statements that could throw an error.

People are using it like VB6's On Error Goto which is still available if that's what you're looking for. IMO, there should only be one line of code in each Try/Catch block aside from a few exceptions.

move you try catch into returnSynonyms. At the point of the exception the execution will move to you catch block.

Put the Try...Catch just around your ReturnSynonyms function, this way:

VB

Dim i As Integer = 0
For i = 0 To RichTextBox2.Lines.Count - 1
    Try
        ReturnSynonyms(RichTextBox2.Lines(0))
    Catch ex As Exception
    End Try
Next
