Since you have tried several times... Show us what you have done so far and maybe someone can see where you are "close but not quite"

namespace son
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
{

int x = e.X;

int y = e.Y;

groupBox1.Location = new Point(x, y);

}
}

private void Form1_Load(object sender, EventArgs e)
{

}
}
}

there is a picturebox on the groupbox...and while i moving the mouse groupbox move with it..but i want it only watch mouse cursor...

By "watch mouse cursor" do you mean you want eyes on the photo that move and appear to be following the cursor? Kind of like this

You need to get the location of the mouse.
Get the location of the graphic
Compare/get angle from one to the other
Draw the eyes at the calculated angle.

You need to get the location of the mouse.
Get the location of the graphic
Compare/get angle from one to the other
Draw the eyes at the calculated angle.

... Or you could hard-code a brute force attack instead. Its your choice.

thanks,
i can get the location of the mouse but
i dont know how can i get location of the graphic, calculate angle and draw the eyes at the angle..
help me...i am beginner...

Drawing eyes.
Read up on the namespace "System.Drawing ". Simple eyes are nothing more than a white oval, with a colored circle inside it, with a black circle inside that.

Mouse coordinates are given relative to the screen. Your graphic location is relative to your form. So you need to convert it's location to its screen location so your are dealing with everything on the same terms.
Read up on the PointToScreen method.

As for the trigonometry to calculate the angles.
Here is a thread that covers it for someone else wanting to do the same thing (calculate the angle and distance of two points on the screen)

Amazing what you can find with Google.
