[Note: In the following exercises, you are asked to create GUIs using controls that we have not yet discussed in this book. The exercises will give you practice with visual programming onlythe programs will not perform any actions. You will be placing controls from the Toolbox on a form to familiarize yourself with what each control looks like. We have provided step-by-step instructions for you. If you follow these, you should be able to replicate the screen images we provide.]
