Check box is a very useful control in Visual Basic 2012. It allows the user to select one or more items by checking the check box or check boxes concerned. For example, in the Font dialog box of any Microsoft Text editor like FrontPage, there are many check boxes under the Effects section such as that shown in the diagram below. The user can choose underline, subscript, small caps, superscript, blink and etc. In Visual Basic 2012, you may create a shopping cart where the user can click on check boxes that correspond to the items they intend to buy, and the total payment can be computed
