CHALLENGES

1. Improve the Joke Machine by adding new buttons that display new jokes.

2. The Joke Machine currently displays only the text string of Form1 in the Windows title bar. Replace this text string with the phrase The Joke Machine. (Hint: Click on the form and modify the form's Text property.)

3. The Joke Machine's TextBox field currently allows the entry of text. Technically, it should display only jokes. Prevent the text box from accepting text. (Hint: Click on the TextBox1 control and set the Readonly property to True.)
