Step-by-Step

Start a new project and add a



Label to its form.

1. Create the new project and its Label.

2. Set the Label’s AutoSize property to False and set its font size to 12. Then position

and anchor it on the form.

3. Set the Label’s TextAlign property to MiddleCenter.

Give the form a



Load event handler that sets the Label’s text as shown in Figure 14-1.

1. Use code similar to the following:

// Display the current date and time.

private void Form1_Load(object sender, EventArgs e)

{

greetingLabel.Text = DateTime.Now.ToString(

“‘It is’ h:mmtt ‘on’ ddd, MMM dd yyyy”);

}

EXERCISES

1. Lesson 13’s Try It reads and displays currency values, but it displays quantities without

thousands separators. If you ordered 1,200 pencils, the program would display 1200.

Copy that program (or download the Lesson 13 Try It from the book’s web site) and modify

it so quantities are displayed with thousands separators.

2. Make a program that displays the time every second. Hint: Use a Timer control with

Enabled set to True, and Interval set to 1000. Update a Label’s Text property in the

Timer’s Tick event.

3. Copy the program that you built for Exercise 1 and modify it so the main form displays items

in a

ListBox instead of a ListView. Make the program use string.Format to add items to

the

ListBox ...
