Class Q5186728
Inherits System.Windows.Forms.Form
Private PictureBox1 As System.Windows.Forms.PictureBox
Public Sub New()

PictureBox1 = new System.Windows.Forms.PictureBox
PictureBox1.Top = 0
PictureBox1.Left = 0
PictureBox1.Width = Me.Width
PictureBox1.Height = Me.Height

AddHandler PictureBox1.Paint, AddressOf Me.PictureBox1_Paint

Me.Controls.Add(PictureBox1)

End Sub

Private Sub PictureBox1_Paint(sender As Object,e As System.Windows.Forms.PaintEventArgs)
'質問の本題そのものはここから
'Meはフォーム(Q5186728のクラスのインスタンス)そのもの
Dim p As System.Drawing.Pen = new System.Drawing.Pen(Me.BackColor)
e.Graphics.Clear(System.Drawing.Color.White)
e.Graphics.DrawLine(p,0,0,PictureBox1.Width,PictureBox1.Height)
End Sub

Shared Sub Main()
Dim f As Q5186728 = new Q5186728()
f.ShowDialog
End Sub
End Class
