Question

How can I set the protected DoubleBuffered property of the controls on a form that are suffering from flicker?

Answer 1

Here’s a more generic version of Dummy’s solution.

We can use reflection to get at the protected DoubleBuffered property, and then it can be set to true.

Note: You should pay your developer taxes and not use double-buffering if the user is running in a terminal services session (e.g. Remote Desktop) This helper method will not turn on double buffering if the person is running in remote desktop.

public static void SetDoubleBuffered(System.Windows.Forms.Control c) {    //Taxes: Remote Desktop Connection and painting    //http://blogs.msdn.com/oldnewthing/archive/2006/01/03/508694.aspx    if (System.Windows.Forms.SystemInformation.TerminalServerSession)       return;     System.Reflection.PropertyInfo aProp =           typeof(System.Windows.Forms.Control).GetProperty(                'DoubleBuffered',                 System.Reflection.BindingFlags.NonPublic |                 System.Reflection.BindingFlags.Instance);     aProp.SetValue(c, true, null);  }
