Hi I am trying to open and view a files text in a rich text box. Here is what I have please let me know what I am doing wrong?

Private Sub loadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles loadButton.Click

    ' Displays an OpenFileDialog so the user can select a Cursor.
    Dim openFileDialog1 As New OpenFileDialog()
    openFileDialog1.Filter = "Cursor Files|*.txt"
    openFileDialog1.Title = "Select a Cursor File"

    If openFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
        ' Assign the cursor in the Stream to the Form's Cursor property.
        Me.mainRTBox = New Text(openFileDialog1.OpenFile())
    End If

End Sub
