how to: make a panel resize with its form; and attach a console for output

1. how to make the Panel widget change it's size on Form1_SizeChanged
2. how to attach a console window in order to see console.writeline messages

1. Take a look at the Anchor and Dock properties on the panel. These let the panel change its size along with the form; you won't need to write any code.
2. It's a little tricky to attach a console to a running app. If you're just interested in seeing debug messages, look at the Visual Studio output window, or call Debug.WriteLine instead.

1. To resize a control when the parent control size changed you can use the Control.Anchor property.

2. To get a console window for a WinForms application just go to Project Properties and change Output type in the Application tab from Windows Application to Console Application.

Easiest way to get your Panel to resize is to Anchor or Dock it into the form. Play with the properties pane a bit and you should see how it works.

Use Anchor or Dock properties. To see the console window in Visual Studio go to the menu View and there you should check displaying "Output".
