Question

im working with a receipt layout and trying to divide up a products descriptiontext into 2 lines if its longer then 24 characters.

my first solution was something like this:

If Row.Description.Length >= 24 Then
TextToPrint &= Row.Description.Substring(0, 24) & "      $100"
TextToPrint &= Row.Description.Substring(24) & vbNewLine
else
 TextToPrint &= Row.Description & filloutFunction(Row.Description.length) &"      $100" & vbNewLine
end if

but that gives this result.

A product with a long na   $100
me that doesn't fit        

I cant figure out how to make a function to divide the description to look like we normaly see it.

A product with a long      $100
name that doesn't fit   

hope i made myself clear /:

My first shot,

private static List<string> SplitSentence(string sentence, int count)
{
    if(sentence.Length <= count)
    {
        return new List<string>()
               {
                   sentence
               };
    }

    string extract = sentence.Substring(0, sentence.Substring(0, count).LastIndexOfAny(new[]
                                                                                      {
                                                                                          ' '
                                                                                      }));

    List<string> list = SplitSentence(sentence.Remove(0, extract.Length), count);

    list.Insert(0, extract.Trim());

    return list;
}

and so :

string sentence = "A product with a long name that doesn't fit";

List<string> sentences = SplitSentence(sentence, 24);
sentences[0] = sentences[0] + "      $100";

I think it’s possible to optimize.
