How would I achive the following. In a text box I've got a number of comma delimited records, and I want to retrieve the last record based on the first delimited item.
For example, if I've got the following rows in the text box:
and the row I want to retrieve is the last 'aa' row (aa,789,789,789).
(BTW if it makes any difference, this is using VB
.NET in the Compact Framework)
