   1x Button
   1x OpenFileDialog

Your form should look like this:

4. Double click the button and add the following codes:

5. Go back to the design of your form and double click the OpenFileDialog1 component. Add the following codes:
Textbox1.Text = OpenfileDialog1.FileName

6. Again, add the following codes to OpenFileDialog1:
Dim Doom As New System.IO.StreamReader(TextBox1.Text)
  TextBox2.Text = Doom.ReadLine()

It should now look like this:

7. Click F5 or run your application.
When you press the button, it will ask you to select a file. Select a textfile and it will read it and place the text in textbox2
