Load TXT Files In Many RichTextBox Using OpenFileDialog In VB?

I have in my form 2 RichTextBox , one Listbox , one OpenFileDialog and one Button . In those 2 RichTextBox I would like to load two (*.RTF) FILES .

Application Steps :

1- When I click the button , an OpenFileDialog open .

2- I choose those two files (*.RTF) and when I press the OK in OpenFileDialog, the path of those two files are written in the ListBox as Items.

3- After getting the path of those two files , I would like to load them into those two richtextboxs .

The problem is that I don't want to specify the richtextboxs names in order to load the files . What am I saying ? I.E : I don't want to use that code : "RichTextBox1.Loadfile(Listbox1.items.item)" When I debug my application : everything goes well , only when the listbox items are loaded in the richtextboxs control I get only one file loaded on those two richtextboxs. Right Now I have written these codes :

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
OpenFileDialog1.Filter = "RTF Files (*.rtf) |*.rtf"
