Here's a quote from
Chapter 6: Using Multiple Threads of the
Smart Client Architecture and Design Guide:
"To maximize the responsiveness of your smart client applications, you need to carefully consider how and when to use multiple threads. Threads can significantly improve the usability and performance of your application, but they require very careful consideration
when you determine how they will interact with the user interface."
.NET Framework 2.0 and the BackgroundWorker component to the rescue! Marc Schweigert, Federal Developer Evangelist, shows you how easy it is to build a responsive multithreaded Smart Client application with Windows Forms 2.0 & the BackgroundWorker component.

Some may say that Channel 9 for them is all about "getting to know personalities at Microsoft". Well, I'll trade all of that for training.
This content is what Channel 9 offers me, and I thank you for it.

Although I know it would be easy to do, it would have been nice had the progress bar been used to show database load progress as well.

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
for (int i = 1; i <= 10; i++)
{
if (backgroundWorker1.CancellationPending)
{
e.Cancel = true;
}
else
{
backgroundWorker1.ReportProgress(i * 10);
Thread.Sleep(1000);
}
}
}
I noticed that this video is no longer working on this site. Is there anyway you can get this video to be functional again?
thanks
