private void UseTransparentProperty()
{

    // Set up the PictureBox to display the entire image, and 
    // to cover the entire client area.
    PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
    PictureBox1.Dock = DockStyle.Fill;

    try
    {
        // Set the Image property of the PictureBox to an image retrieved 
        // from the file system.
        PictureBox1.Image = 
            Image.FromFile("C:\\Documents and Settings\\All Users\\" +
            "Documents\\My Pictures\\Sample Pictures\\sunset.jpg");

        // Set the Parent property of Button1 and Button2 to the  
        // PictureBox.
        Button1.Parent = PictureBox1;
        Button2.Parent = PictureBox1;

        // Set the Color property of both buttons to transparent.  
        // With this setting the buttons assume the color of their 
        // parent.
        Button1.BackColor = Color.Transparent;
        Button2.BackColor = Color.Transparent;

    }
    catch(System.IO.FileNotFoundException)
    {
        MessageBox.Show("There was an error." +
            "Make sure the image file path is valid.");
    }
