Screen Saver Using C#

Introduction:

In this article I will show you how to make a screen saver by using c# windows form. It is not perfect screen sever as windows gives us but yes, it is little bit like that.

Steps:

1) Add a form in your application and make it form border style none. Set transparency key as form background color so it will make your form transparent.

2) Put a timer control on your form and set it's interval as you want to display picture per millisecond on the computer screen.

3) Code behind

int x, y;
private void timer1_Tick(object sender, EventArgs e)

{

* here x & y are the variables and below two line will put desktop's different

* screen location in it.

x = Convert.ToInt32((Microsoft.VisualBasic.VBMath.Rnd()) * (this.ClientSize.Width));

y =Convert.ToInt32((Microsoft.VisualBasic.VBMath.Rnd())*this.ClientSize.Height));

* screenStart() is the function which works to display image at the different screen

* location of the desktop

screenStart();

}

//This is the function which is called in the time1_Tick even

private void screenStart()

{

//Picturebox is created dyanamically

PictureBox pbox = new PictureBox();

//and then after it will display at different location

pbox.Location = new Point(x, y);

pbox.Height = 100;

pbox.Width = 100;

//picture is set to the picturebox from the Resources.

pbox.Image = global::screensever.Properties.Resources.thank_you_blue_rose;

pbox.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage;

//and at last control will added to the form

Controls.Add(pbox);

}

//This the Form1_Keyup even from where you will exit from the application while its running.

private void Form1_KeyUp(object sender, KeyEventArgs e)

{

if (Keys.Escape == e.KeyCode)

{

this.Close();

}
