CT218 Lab1b

Today you will create a small application that accepts ordering information for customised sundaes in an ice-cream parlour. It should be contained in a single form which should look something like this:

• The 3 check-boxes inside the “Options” frame will allow the user to select any combination of these options.

• The 4 option-buttons inside the “Number of scoops” frame will allow the user to select only one of these options. You should make the “1” option button be automatically chosen when the application first starts – do this by setting its Value property to True at design-time.

• Make the text-box labelled “Table Number” only accept numerical input – i.e. write an event procedure for the KeyPress event in this text box, which will identify and cancel non-numerical input (see lecture notes!)

• The button labelled “Exit” should be used to end the application (see last week’s lab sheet)

• If you have time, try to make the “Exit” button’s Click event procedure validate the “Table Number” text box, by making sure that something has been typed in it. (Hint: check for and reject a situation where the text box is empty, i.e. its Text property = “” - see lecture notes). Notify the user with a message box and do not exit the application if this is the case.
