 Hey everybody, this is Brian, and if you're following along, this is our ninth video in our VB series. I wanted to revisit the do loop. Your homework from the last time was to determine the difference between do until and do while. Do until will loop until a certain criteria is met. In this case, we're going to loop until i equals 5, and then obviously we're incrementing i as we go. Do while will loop while a certain criteria is true. i is less than 5. Now, why would you use these two? I mean, you see in this example, let's actually run it. They both do the same thing, so why would you do this at all? Well, do until is your normal workhorse at your basic loop. Do while is typically done for like graphics or yeah, I'm trying to think of a good one. Socket transfers, transferring data across the internet, you know, do while the file is still being downloaded, that sort of thing. But you can also do it do until do until the entire file is downloaded. It's really personal choice. VB is very flexible, allows you to do things your way. So that's the answer to that question. I hope you found this video educational and entertaining, and as always send me your questions.
