  hello guys ... this is my first post here ...

  as far as i know ... the method of enabling double buffering in Visual Basic is ...

  Public Sub New()
      MyBase.New()
  

      'This call is required by the Windows Form Designer.
      InitializeComponent()
  

      'Add any initialization after the InitializeComponent() call
      Me.SetStyle(ControlStyles.DoubleBuffer Or ControlStyles.UserPaint Or ControlStyles.AllPaintingInWmPaint, True)
      Me.UpdateStyles()
  End Sub
  
  
  

   

  i have tried it ... but it is not working ... any suggestions please ?

  do we have to write a certain type of code ... or draw with a certain refresh rate ... to make double buffering effective ??

  Hi,

  Try putting the code in the Form_Load event, like this:

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or _
      ControlStyles.UserPaint Or _
      ControlStyles.DoubleBuffer, True)
  End Sub
  

  Good luck.

  Try setting the form's DoubleBuffered property to True in the designer.

  Yes there is.  Use .NET 2.0.  If you tell us what version you're using then we can avoid giving advice that isn't applicable.

  Hi hammad

  Put under form load event:

    'Stop the flicker
    me.SetStyle(ControlStyles.DoubleBuffer, true)
    me.SetStyle(ControlStyles.AllPaintingInWmPaint, true)

  Hi hammad

  Use this tip:

  Call SuspendLayout  to delay painting and ResumeLayout methods after everything is positioned correctly
