Got nasty VB.Net ListView flicker? Double Buffer it

Posted
Coding Double Buffer ListView VB.NET

The solution is so painfully obvious, I wish I had thought of it sooner.

In the designer, all you have to do is change your Inherits line to inherit from the ListView object and remove that Autowhatsit in the InitializeComponent function.

ucListViewDoubleBuffered.Designer.vb:

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class ListViewDoubleBuffered
    Inherits System.Windows.Forms.ListView

    'UserControl overrides dispose to clean up the component list.
    <System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing AndAlso components IsNot Nothing Then
            components.Dispose()
        End If
        MyBase.Dispose(disposing)
    End Sub

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

    '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.
    <System.Diagnostics.DebuggerStepThrough()> _
    Private Sub InitializeComponent()
        components = New System.ComponentModel.Container()
    End Sub

End Class

Then in the code behind, write a constructor and set its styles appropriately.

ucListViewDoubleBuffered.vb:

Imports System.Windows.Forms

Public Class ListViewDoubleBuffered
    Inherits ListView

    Public Sub New()
        MyBase.New()
        InitializeComponent()
        Me.SetStyle(ControlStyles.DoubleBuffer, True)
        Me.SetStyle(ControlStyles.Opaque, True)
    End Sub

End Class

Bam. Instant double buffered control.

Don't have VB.Net 2005? Don't worry. You can still get flicker-freeness by making the following changes to the code behind a default user control.

1) Replace the inherits line, located directly under the Public Class line, with this:

Inherits System.Windows.Forms.ListView

2) At the end of Public Sub New, add this:

Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.Opaque, True)

Don't forget to build your project before using.

Thanks!!! I can see an improvement already, and my process CPU usage is waaaaaay down.

Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)

All Flicker gone :)

Both work in this case. Opaque vs. AllPaintingInWmPaint for other cases, though, would be an interesting topic for another discussion. Perhaps if I run across this issue again, I'll bring it up. Thanks for the input. :)

In California, truck license plates are 7 characters, all numbers except for one letter in either the second or the sixth position. Whenever that letter is an X, I get nerd snipped into treating it as a multiplication problem and solving it in my head.

Former 2 time world champion DogPlayingTetris becomes the first player to ever rollover the level counter in NES Tetris, performing what's known in the community as "Rebirth". Final score: 29,486,164, 4216 lines, level 347 (256 + 91)... all huge world records. #tetris

I updated the blog post with a statement from Revival. While I'm not particularly happy with Revival's decision, I understand their motives. It's just a shame that it was someone from Interplay that had to go and do this. "By games for gamers" my ass.
