The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a black pen.

  • Creates an array of points of segments of the line.

  • Draws the connected line segments to the screen.

Public Sub DrawLinesPoint(ByVal e As PaintEventArgs)

    ' Create pen. 
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create array of points that define lines to draw. 
    Dim points As Point() = {New Point(10, 10), New Point(10, 100), _
    New Point(200, 50), New Point(250, 300)}

    'Draw lines to screen.
    e.Graphics.DrawLines(blackPen, points)
End Sub
