I am teaching BackgroundWorker at the moment, and I gave two demos of using it, one with printing and one with the classic long request to the database.
For the student work, I needed to find another sample that I could give them. I tend to like reasonable examples, rather than Hello world ones. I build them the following code to excersize:
WebRequest req = WebRequest.Create("http://www.msdn.com/");
using (WebResponse response = req.GetResponse())
string homePageHTML =
textBox1.Text = homePageHTML ;
At first I tried Google, but that was too fast to be a good demo, msdn.com takes ~15 seconds to get everything from the server, good, solid reason for why we need scalable application.
Sigh, this is so wrong!
