There are three objects placed on FlightForm where the value is calculated: vTotalCharge, vEmployeeLastName, and #DATE. The user does not enter or modify these values. We can specify settings for these objects to prevent users from changing data in these fields. We will also exclude the object from being enabled in the cursor tab order. The Tab Order is the order in which you place objects on a form is the order R:BASE prompts you to enter data. Next in this chapter you will review how to edit the Tab Order.
To change an object's properties:
| 1. | In the "Form Designer" window, click on the vTotalCharge variable object, right click, and choose Object Property. |
The "Variable Edit Properties" dialog box is displayed.
| 2. | Check the "Read Only" option, and uncheck the "Tab Stop" and "Autoselect" fields options. |
The "Autoselect" option will toggle whether all of the text in the field is selected or if just a blinking cursor will appear. The "Tab Stop" check box toggles whether or not the field is part of Tab Order, which is discussed next.
| 3. | Click the OK button. |
Repeat this procedure for the vEmployeeLastName and #DATE variable objects.
