[2005] Saving/Printing Files

How do i make a program that acts in the same way as microsoft word?

The only things i need to know for this program is Saving and Printing the string value in the file.

Saving:

vb Code:

Private Sub butSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butSave.Click
        Dim Savefile1 As New SaveFileDialog
        Savefile1.DefaultExt = ("*.rtf")
        Savefile1.Filter = "RTF Files|*.rtf"
        If (Savefile1.ShowDialog = System.Windows.Forms.DialogResult.OK) And (Savefile1.FileName.Length > 0) Then
            RichTextBox1.SaveFile(Savefile1.FileName)
        End If
    End Sub
