Check Boxes

Check boxes were created to provide the user the opportunity to select more than one option. Nothing happens until the user clicks on the Continue button at the bottom of the window. The group box is placed on the window template first and the three check boxes are placed onto the group box.

Figure 19-4: Check Boxes window

The user can pick any combination of the three check boxes (checked or unchecked, where a checked item has a black check mark in its box, and unchecked is blank). Once the user selections have been made, the Continue button is clicked to invoke the event handler. The code for this window is shown below:
