GDI+ with Visual Basic.NET

I want to use GDI+ in VB.NET, so I have been trying to draw a line first, but I think I `m doing something wrong ; VB.NET gives error as : An unhandled exception of type 'System.NullReferenceException' occurred in C:\MY DOCUMENTS\VISUAL STUDIO PROJECTS\WINDOWSAPPLICATION3\BIN\WINDOWSAPPLICATION3.EXE

The code is :

Imports System.ComponentModel
Imports System.Drawing
Imports System.WinForms

Public Class Form1
Inherits System.WinForms.Form

Public Sub New()
MyBase.New

Form1 = Me

'This call is required by the Win Form Designer.
InitializeComponent

'TODO: Add any initialization after the InitializeComponent() call
End Sub

'Form overrides dispose to clean up the component list.
Overrides Public Sub Dispose()
MyBase.Dispose
components.Dispose
End Sub

#Region " Windows Form Designer generated code "

'Required by the Windows Form Designer
Private components As System.ComponentModel.Container

Dim WithEvents Form1 As System.WinForms.Form

'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
Private Sub InitializeComponent()
Me.components = New System.ComponentModel.Container()
'@design Me.TrayHeight = 90
'@design Me.TrayLargeIcon = False
'@design Me.TrayAutoArrange = True
Me.Text = "Form1"
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(424, 317)

End Sub

#End Region

Private Sub DrawALine()
Dim e As PaintEventArgs
Dim myPath As New Drawing2D.GraphicsPath()
myPath.AddLine(10, 50, 100, 150)
Dim myPen As New Drawing.Pen(Color.Black, 2)
e.Graphics.DrawPath(myPen, myPath)
End Sub

Public Sub Form1_Paint(ByVal sender As Object, ByVal e As System.WinForms.PaintEventArgs) Handles Form1.Paint
DrawALine()
End Sub

End Class
