如下代码中,实现画一个图形,然后我希望能自动重画保留此图形,类似vb6.0 中picture.autoRedraw=Ture功能,希望得到详细代码,谢谢
Private Sub Picture1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Picture1.Click
' Create a Pen object.
Dim pen As New Drawing.Pen(System.Drawing.Color.Red, 1)
Picture1.CreateGraphics.DrawEllipse(pen, 0, 0, 100, 100)
pen.Dispose()
End Sub
Private Sub Picture1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Picture1.Click
' Create a Pen object.
Dim pen As New Drawing.Pen(System.Drawing.Color.Red, 1)
Picture1.CreateGraphics.DrawEllipse(pen, 0, 0, 100, 100)
pen.Dispose()
End Sub
