Labels in C#

•The Label control is probably the most frequently used control of them all.

•Label is a simple control with one purpose only (to display text on the form).

•Usually, you don’t need to add event handling code for a standard Label, although it does support events, like all controls.

•You can set a number of properties for the Label control.

•AutoEllipsis: Gets or sets a value indicating whether the ellipsis character (...) appears at the right edge of the Label, denoting that the Label text extends beyond the specified length of the Label.

Design a Digital Clock

To design a simple digital clock we need the following controls and classes:

1 - labels: to display time on it.
2 - Timer Control: to call the time .

● Enabled : Gets or sets a value indicating whether the Timer should raise the Elapsed event.

● Interval: Gets or sets the interval at which to raise the Elapsed event.

● Start: Starts raising the Elapsed event by setting

Enabled to true.

● Stop: Stops raising the Elapsed event by setting

Enabled to false.

3 - DataTime class: to obtain time.

● DateTime class is used to obtain date and time.

● To return the current date and time we use

DateTime.Now

● For example,

Datetime now = new DateTime.Now;

Now Lets start the design

First of all drag two labels to the form then drag a Timer Control and change the properties as following:

● Label1:

– Text: Time

– Font: 16 bold

● Label2:

– Text: empty

– Font: 16 bold

● Timer:

– Interval:1000

– Enable : true

Then write the following code in the form load

private void Form1_Load(object sender,

EventArgs e)

{

timer1.Start();

}

Then write the following code in the timer event

private void timer1_Tick(object sender,

EventArgs e)

{

DateTime now = DateTime.Now;

label2.Text = now.ToLongTimeString();

}
