Get Full Value of Fileupload path

Hi,
 
I have a file upload control on my webform. When I want to use it to select a text file. I will not be uploaded the file however, I will need the value of the path so I can open the text file with the streamreader. I then will pass the value of the text file to a database. How do I get the value of the fileupload textbox?
 
Here is my code so far:

  
Dim FILENAME As String = NEED VALUE OF FILEUPLOAD TEXTBOX VALUE HERE Dim myfile As String Dim objStreamReader As StreamReader objStreamReader = File.OpenText(myfile.Text) Dim contents As String = objStreamReader.ReadToEnd() t.Text = contents objStreamReader.Close()  ...
