private:
   void WriteTextToRichTextBox()
   {
      // Clear all text from the RichTextBox;
      richTextBox1->Clear();

      // Set the font for the opening text to a larger Arial font;
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",16 );

      // Assign the introduction text to the RichTextBox control.
      richTextBox1->SelectedText = "The following is a list of bulleted items: \n";

      // Set the Font for the first item to a smaller size Arial font.
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",12 );

      // Specify that the following items are to be added to a bulleted list.
      richTextBox1->SelectionBullet = true;

      // Set the color of the item text.
      richTextBox1->SelectionColor = Color::Red;

      // Assign the text to the bulleted item.
      richTextBox1->SelectedText = "Apples \n";

      // Apply same font since font settings do not carry to next line.
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",12 );

      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",16 );
      richTextBox1->SelectedText = "Bulleted Text Complete!";
   }
