• SQL Server Query help - get last username?

  Hi, I hope this is the right place to post this. I am pretty much stuck but think I am doing pretty good so far as I am getting more and more into SQL using SQL Server 2000 here.   I want to be able to get the last username who replied to a topic.

I know you can set it to OwnerDraw, or something like that, but I'm a little fuzzy on what exactly I'd have to do there. Hello Kris, yes Genius is right. If you want to set the DoubleBuffer you have to extend the ListView since it is a protec ...Show All
