You don't want to "call a class", you want to "call a method in some class".

That method apparently should change the color of a selection in a richtextbox in your form. The way to do that is to give that editor control as parameter to your method.

something like:

namespace TE
{
    public class High
    {
        public static void ChangeSelection(RichTextBox rtb)
        {
            rtb.SelectionColor = Color.Black;
            rtb.SelectionFont = new Font("Courier New", 10, FontStyle.Regular);
        }
    }
}

and use it from the form like:

private void TextChangedEvent(object sender, EventArgs e)
{
    TE.High.ChangeSelection(rtb); // assuming 'rtb' is your control
}

sir how to call it when the RichTextBox was assigned in mainform error in class (rtb) heres the code: public class DtexteditoR : Form { RichTextBox rtb = null; public Dedit() { } — , Mar 01 '13 at 11:11

You should have the color-changing code in a method like this:

 namespace TE
{
    public class High
    {
        public static void ChangeMyColor(RichTextBox rtb)
        {

            rtb.SelectionColor = Color.Black;
            rtb.SelectionFont = new Font("Courier New", 10, FontStyle.Regular);
        }
    }
}

Call it like this:

private void TextChangedEvent(object sender, EventArgs e)
{
    TE.High.ChangeMyColor(rtb);
}
