Dim p1 As WinForm.SplitPanel = e.Form.Controls("SplitContainer1").Panel1
Dim p2 As WinForm.SplitPanel = e.Form.Controls("SplitContainer1").Panel2
p1.baseControl.Gettype().GetProperty("DoubleBuffered", Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.NonPublic).SetValue(p1.baseControl,True,Nothing)
p2.baseControl.Gettype().GetProperty("DoubleBuffered", Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.NonPublic).SetValue(p2.baseControl,True,Nothing)
