Irish Code?

Q: Why did the Irishman wear two condoms?
A: To be sure, to be sure.
(Apologies to any Irish who happen to be reading this.)

I’m currently working on a project where I need to upgrade an application to support some new functionality.   This application was originally written by others,

While I was doing a review of the code, I found a segment like this (names anonymised): 

        CountOfIDs = ds.Tables("SomeTable").Rows.Count
        Select Case CountOfIDs
            Case 0
                ' Do Nothing 
            Case Is >= 1
                If CountOfIDs >= 1 Then
                    ' Do Something
                End If
        End Select

Those IDs are slippery little things – better check twice, to be sure.
(Hint for the C#/C++/etc readers: VB doesn’t need a ‘break’ statement to exit a select/switch block)

    Break statements are nice in some cases when you want the code to follow into the next statement.

    ie
    switch (message)
    {
    case ‘notErr’: ; break;
    case ‘err1′:
    case ‘err2′:
    case ‘err3′: MessageBox.Show(“An error occured!”+message);
    break;
    }

    I know, there’s plenty of other very handy uses for them too :)
