Cross Thread operations

For quiet some time now I have been using random ways to doing begin invoke. Here is a good pattern for it.

   1: public partial class Form1 : Form

   2: {

   3:     public Form1()

   4:     {

   5:         InitializeComponent();

   6:     }

   7:  

   8:     private void Form1_Load(object sender, EventArgs e)

   9:     {

  10:         ControlsHelper.SafeGui(this, delegate()

  11:         {

  12:             textBox1.Text = "using ControlsHelper on UI thread"; // this succeeds

  13:         });

  14:         Thread t = new Thread(new ThreadStart(WorkOnNewThread));

  15:         t.Start();

  16:     }

  17:     private void WorkOnNewThread()

  18:     {

  19:         ControlsHelper.SafeGui(this, delegate()

  20:         {

  21:             textBox1.Text = "using ControlsHelper"; // this succeeds

  22:         });

  23:  

  24:         textBox1.Text = "direct"; // this fails

  25:     }

  26: }

  27:  

  28: public static class ControlsHelper

  29: {

  30:     public static void SafeGui(Control control, MethodInvoker invoker)

  31:     {

  32:         if (null == invoker) return;

  33:         if (control != null)

  34:         {

  35:             if (control.InvokeRequired)

  36:                 control.BeginInvoke(invoker, null);

  37:             else

  38:                 invoker();

  39:         }

  40:         else

  41:             invoker();

  42:     }

  43: }
