при событии Mouse Down

И, кстати, что за событие такое?

    Private Sub PictureBox_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox.MouseDown

            Dim pen As New Drawing.Pen(System.Drawing.Color.Red, 2)

            Dim g As Graphics = PictureBox.CreateGraphics

            g.DrawEllipse(pen, e.X - 3, e.Y - 3, 6, 6)

            pen.Dispose

    End Sub

BASIC /bay'-sic/ /n./ [acronym: Beginner's All-purpose Symbolic Instruction Code] A programming language, originally designed for Dartmouth's experimental timesharing system in the early 1960s, which has since become the leading cause of brain damage in proto-hackers. Edsger W. Dijkstra observed in "Selected Writings on Computing: A Personal Perspective" that "It is practically impossible to teach good programming style to students that have had prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration."
