Can a ComboBox list all txt file in a folder?

I'm using VS10 and what I like to do is put about 10 to 15 txt notes in a folder. Then with a combobox or a list box  it will show all txt files  in the folder and the text you select will show in the text box of the form.

Right now all I got is a button to open a text from a folder and to show it text box by using this:

Dim FILE_NAMEAsString = "C:\test.txt"

       Dim objReader AsNew System.IO.StreamReader(FILE_NAME)

        TextBox1.Text = objReader.ReadToEnd

        objReader.Close()

The reason I would like to change to a combobox or even a list box is it would be easier for me to make changes to the txt file or add to or delete file.

Is this something that can be done?

Thanks
