3. • The Timer Control plays an important role in the
development of programs development in Windows
Services.
• With the Timer Control we can raise events at a
specific interval of time without the interaction of
another event.

4. example
• add a timer & a
label to the form.

5. coding
• double click on timer1 menu item and write the
following code:
private void timer1_Tick(object sender, EventArgs e)
{
label1.Text = DateTime.Now.ToString();
}

6. timer1 set properties

7. running

8. {
{
SoundPlayer p = new SoundPlayer();
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
label5.Text = "Set...";
}
private void button2_Click(object sender, EventArgs e)
{
p.Stop();
label5.Text = "Stop...";
timer1.Enabled = false;
}
Note: add (using System.Media;) to project
libraries

9. private void timer1_Tick(object sender, EventArgs e)
{
if if (DateTime.Now.Hour == numericUpDown1.Value &&
DateTime.Now.Minute == numericUpDown2.Value &&
DateTime.Now.Second == numericUpDown3.Value)
{
p.SoundLocation = @"C:WindowsMediaAlarm10.wav";
p.PlayLooping();
}
}
private void timer2_Tick(object sender, EventArgs e)
{
label4.Text = DateTime.Now.ToLongTimeString();
}
}
}

10. A splash screen is a graphical control element consisting of a window containing an
image, a logo, and the current version of the software. A splash screen usually appears
while a program is launching.

11. private void timer1_Tick(object sender, EventArgs e)
{
Form2 fr = new Form2();
this.Hide();
fr.Show();
timer1.Enabled = false;
}
private void timer2_Tick(object sender, EventArgs e)
{
Random r = new Random();
label1.ForeColor = Color.FromArgb(r.Next(0,255), r.Next(0, 255),r.Next(0, 255));
}
