Using a custom TextBox to trap the Tab key. I dropped the custom TextBox onto the Window Form.
I have discovered how to refer to the controls on the Form from within the class.
Form f = Application.OpenForms["Form1"] as Form;
string s = f.Controls["tabTextBox1"].Text;
I still need to access an ErrorProvider on the form and can't get the syntax correct. I can see them but just can't determine how to access them.

I found an example online that used Reflection. Hoping there is an easier way.
