Some of the graphics methods use points. A point is a class that has members X and Y. When you declare an instance of the Point or PointF class, you give X and Y as the arguments.
The DrawLine method has 4 possible argument lists.
The code below uses the fourth format:
Public Class Form1 Private Sub Form1_MouseClick(sender As Object, e As MouseEventArgs) Handles Me.MouseClick Dim MyPoint1 As New Point(e.X - 10, e.Y - 10) Dim MyPoint2 As New Point(e.X + 10, e.Y + 10) Dim MyPen As New Pen(Color.Goldenrod, 3) Me.CreateGraphics.DrawLine(MyPen, MyPoint1, MyPoint2) End Sub End Class
