LblDisplay.Font = New Font(LblDisplay.Font, And Not FontStyle.Italic) Will retain the original font type but change it to italic font style. The statement LblDisplay.Font = New Font(LblDisplay.Font, Or FontStyle.Italic) * The above visual basic 2017 program uses the CheckedChanged event to respond to the user selection by checking a particular checkbox, it is similar to the click event. LblDisplay.Font = New Font(LblDisplay.Font, And Not FontStyle.Underline) LblDisplay.Font = New Font(LblDisplay.Font, Or FontStyle.Underline) Private Sub ChkUnder_CheckedChanged(sender As Object, e As EventArgs) Handles ChkUnder.CheckedChanged LblDisplay.Font = New Font(LblDisplay.Font, Or FontStyle.Italic) Private Sub ChkItalic_CheckedChanged(sender As Object, e As EventArgs) Handles ChkItalic.CheckedChanged LblDisplay.Font = New Font(LblDisplay.Font, And Not FontStyle.Bold) LblDisplay.Font = New Font(LblDisplay.Font, Or FontStyle.Bold) Private Sub ChkBold_CheckedChanged(sender As Object, e As EventArgs) Handles ChkBold.CheckedChanged In this example, the text on the label can be formatting using the three checkboxes that represent bold, italic and underline. Private Sub BtnReset_Click(sender As Object, e As EventArgs) Handles BtnReset.ClickĮxample 21.2 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Private Sub BtnCal_Click(sender As Object, e As EventArgs) Handles BtnCal.Click Finally, we use the ToString is a Visual Basic 2017 method to display the amount in currency. For example, sum+=BN is actually sum=sum+BN. To calculate the total amount of purchase, we use the mathematical operator +=. If a checkbox is being ticked, its state is True else its state is False. We declare the price of each item using the Const keyword. In this example, we add a few labels, two buttons, and six checkboxes. In Visual Basic 2017, you can create a shopping cart where the user can click on checkboxes that correspond to the items they intend to buy, and the total payment can be computed at the same time. The user can choose to underline, subscript, small caps, superscript, blink and etc. For example, in the Font dialog box of any Microsoft Text editor like FrontPage, there are many checkboxes under the Effects section. The Checkbox allows the user to select one or more items by checking the checkbox or checkboxes concerned. In this lesson, we shall learn about the checkbox.
