By now you've likely heard about the major new features coming in VB 2010, but there's also a number of smaller additions in the language and IDE that might not be as readily noticeable.

VBTeam November 16, 2009 Nov 16, 2009 11/16/09

This one’s going to be long, but for those of you who’ve felt the first 3 in this series were too easy I promise this one’s tougher J. Let’s say you want to list all the customers from a table in a ComboBox, and update the UI based on which one is selected. To do this we’ll need to bring back two fields...
