Hey all, I'm new to WPFs and I need to learn it. I can do VB.net and C# rather well, so I only need to know a few things.

How to do you use controls and their properties? I have a text box, and i need to know how (and where) to reference its contents. I tried to reference it in a button_click event but it didn't like that at all.

How do you manage multiple forms (...or whatever they're called)?
