Interesting but not quite the design issue I have in mind. See http://www.danielpride.com/Vehicles3/Vehicles3.html
(Its still a little crude, basically playing with the tech. Clicking on a row fills in a series of text boxes. if you edit a box, I want to shift the state just like it does now when you click the new button at the top, except now it will go to an edit state. The idea is you can examine a large data record by selecting it from a row of important fields, then edit if you like or just look. Its easy enough to compare the values field by field but in my old language I would have written a very small function with two pointers (new and old) and then just called the same function in each focus out, passing in the two pointers to the current field of the focus event. This has got to be childs play I would think but newbie status prevents it from popping out of my head I guess.
