I'm quite new to VB.NET, what's the best design format to create an application? Here's what I want to do. I want to do something similar to MS Outlook where if you click on the Inbox on the left, the right side interface changes and if you click on the Contact, again, the right side interface changes. Now, more precise questions. How is this done? Is this done by using panel? If it is, is this panel created at run time or design time? And back to my original question, what's the best design? I only have three things for now. If I'm going to use panels, I will only need three panels to display three different information.

Many thanks for your help!
