In case anyone is interested, here's the VB.Net version of the multi-tweet code:

Code:

        If Tweet_TextBox.Text.Length > 140 Then
            Do While tempTweet.Length >= 132
                chunkCut = 132
                While tempTweet.Substring(chunkCut, 1) <> " "
                    'test for punctuation too (?!,;)
                    chunkCut = chunkCut - 1
                End While
                tweetChunk(chunkCount) = tempTweet.Substring(0, chunkCut).Trim
                tempTweet = tempTweet.Remove(0, chunkCut)
                chunkCount = chunkCount + 1
            Loop
            tweetChunk(chunkCount) = tempTweet.Trim
            For tweets = 0 To chunkCount
                tweetUpdate = (tweets + 1).ToString & "/" & (chunkCount + 1).ToString & " " & tweetChunk(tweets)
                If tweets < chunkCount Then tweetUpdate = tweetUpdate & " +"
                tw.Update(tweetUpdate)
            Next
        Else
            tw.Update(Tweet_TextBox.Text)
        End If
        Tweet_TextBox.Clear()

Basically it looks to see if the tweet has more than 140 characters, and if so, breaks it down into serialized chunks. Because it can't predict the number of chunks accurately, I allow for prefixed serial part to be xx/yy so if it's x/y then the tweet "misses" 3 characters for total length (I add a space too). In addition, I add a space and + character at the end so that's 2 more. In other words, most tweets will be 135 characters or less.
