try-catch .vs. "on error"

[tg2003]

Hi,

I'm a VB.NET rookie, but a VB6 veteran.

I would like to ask you what is considered better in VB.NET.

I would like to catch run-time errors.

In VB6 I use "on error resume next / goto ..."

I see that in VB.NET I have the try-catch, just like C++ and Java.

What's better? pros and cons?

Thanks in advance!

Try-Catch is far better than On Error-Goto. For one thing, you can use Finally after Try-Catch to clean up after an error or successful completion of the code block.

Try
'do some stuff
Catch
'handle errors
Finally
'clean up
End Try

jebenson has it right. I've been using VB.Net for 6 six years and have never used On Error GoTo in .Net. Rarely do I used GoTo at all.

On Error Goto is not even available in .net.

Here's a link that explains it:

On Error Resume Next", "On Error goto 0", "On Error goto -1" and "On Error Goto [label]" are still supported at least in .Net 1.1.

In some cases where a line of code is optional, on error resume next may be faster that the whole try catch logic.
