Custom Test Type Example InitializeComponent

I am trying to create a custom test type in .NET  following the example.

I pasted the code in the example, but some of the methods and attributes are not resolving.

Specifically the m_textBox, InitializeComponent() and TestTypeResource references are not being found.

What do I need to do to clean this up?

I am very new to .NET and would really appreciate some guidance to get me started on this.

Thanks in advance.
