Ok, I have some code that looks like
Catch ex As Exception

end try
I need some code to detect which type of exception is thrown. This should look like:
    If ex.StatusCode = SmtpStatusCode.InsufficientStorage Then
    End If
However, ex.statuscode doesn't work for VB. I belive it's just for asp.net. What do I use for vb?

Here is a quick sample of some of the things you can do with Try/Catch....
You can add alot of catches and even nest them in each catch.
Dim res as Integer
            cmd1.CommandText = gSql
            res = cmd1.ExecuteNonQuery
            If res < 1 Then
                If bFinish = True Then
                    If res = 0 Then Exit Try
                    Throw New System.Exception()
                End If
            End If
        Catch ex As InsufficientMemoryException
            MsgBox("Exception: " & ex.Message & "  " & ex.ToString, MsgBoxStyle.Critical)
            Exit Sub
        Catch ex As AccessViolationException
            MsgBox("Exception: " & ex.Message & "  " & ex.ToString, MsgBoxStyle.Critical)
            Exit Sub
        Catch ex As Exception When res < 1
            ErrorText = "Database update failed. Please try again."
            MsgBox("Exception: " & ErrorText & vbNewLine & "Error #: " & ErrorNumber, MsgBoxStyle.Critical)
            Exit Sub
        Catch ex As Exception
            MsgBox("Exception: " & ex.Message & "  " & ex.ToString, MsgBoxStyle.Critical)
            Exit Sub
        End Try
