Private Sub 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 ex As System.IO.FileNotFoundException
        MessageBox.Show("There was an error." _
        & "Make sure the image file path is valid.")
    End Try


End Sub


private void UseTransparentProperty()
{

    // Set up the PictureBox to display the entire image, and
    // to cover the entire client area.
