visual basic

Exercises 1. Use the knowledge you've gained so far to create a new project with a form that is gray at design time but that appears blue when it is displayed. 2. Create a project with a form and a text box. Add code to the TextChange event to cause a recursion when the user types in text. Hint: Concatenate a character to the end of the user's text, using a statement such as the following: TextBox1. Text = TextBox1. Text \& "a" 3. The ampersand tells Visual Basic to add the letter a to the end of the existing text box contents. Notice how you eventually get a stack overflow error-not a good thing
