i made a form with a textbox and a richbox....
The thextbox is : Command editor
and the Richbox is : Command history
All my commands that i entered in command editor goes into "QueryCommands.txt".
How can i make the Richbox to update automaticaly after i write a Command into a command editor.

```
private void WW_Shown(object sender, EventArgs e)
{
    string strfilename = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "QueryCommands.txt");
    string commandstext = File.ReadAllText(strfilename);
    richTextBox2.Text = commandstext;
}

```

this is the Richbox loader... I need to Load everytime The Form to make an update.. And i want that the richbox loads the commands automaticaly the commands from my QueryCommands.txt
