At runtime, the visibility of a form control is determined by the control's associated attribute.

Is this correct, or is it incorrect? When a form is created for the first time, its Text attribute has the same value as the form's name. This is carried out as part of the startup procedure

In the same way that attributes dictate whether or not a control is shown on the form at runtime, attributes also determine whether or not a control is displayed on the form at design time.

Include a comment in the code that includes the assignment name, your name, and the date The web site title is Your name Include a header that is Your Name, Calculate Shipping and Handling Include a text box to allow the user to enter the purchase price Include a label for the text box Include a button to allow the user to get the shipping & handling fee Include a JavaScript function to calculate shipping and handling The shipping and handling fee is calculated as follows: If the order total is $25 or less, the fee is $1.50 If the order total is more than $25, the fee is 10% of the order total; use the following formula: S&H Fee = Purchase Price * 0.10 After determining the shipping & handling fee, add it to the purchase price and display the order total in an alert box (include a message such as "The order total is: " with the total)

Create a sub procedure called Inventory that passes two parameters: cost and item. This procedure should print the item and the cost using a label object(s).

In the same way that attributes dictate whether or not a control is shown on the form at runtime, attributes also determine whether or not a control is displayed on the form at design time.

The attribute of the control decides whether or not it will appear on the form.
