        New1()
        End
    End Sub

End Class

Answer 1

Is it throw an exception that is neither a DocumentException nor a IOException?

Answer 2

  Dim jpeg As Image = Image.GetInstance("test.jpg")

Is likely throwing an exception type you are not handling.

Try adding

Catch e As Exception
   Console.Error.WriteLine(e.Message)

This is just for debugging purposes though, and I would replace Exception with the actual type of exception that is being thrown. In general it's a real bad idea to catch System.Exception

Answer 3

Do this to see what exception is being thrown.

Catch e As Exception
    Console.WriteLine(e.GetType().Name)
    Console.WriteLine(e.Message)
 End Try

Answer 4

Try throwing another "Catch ex as Exception" before "End Try". You may be trying to catch the wrong exception.
