How to: Draw a Line on a Windows Form
This example draws a line on a form. Typically, when you draw on a form, you handle the form’s Paint event and perform the drawing using the Graphics property of the PaintEventArgs, as shown in this example
Example
Dim pen As New Pen(Color.FromArgb(255, 0, 0, 0))
e.Graphics.DrawLine(pen, 20, 10, 300, 100)
Pen pen = new Pen(Color.FromArgb(255, 0, 0, 0));
e.Graphics.DrawLine(pen, 20, 10, 300, 100);
Compiling the Code
The preceding example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler.
Robust Programming
You should always call Dispose on any objects that consume system resources, such as Pen objects.
