How do I Delete the real file from the server using a delete button

Hi, i've been trying to write codes that will delete a file from my databae and also the real file from the server. I can success fully delete the URL from the database but i also want to delete the real file. I used the File upload control to allow users upload a file. I want to also give them a chance to delete it using a button. this is my code: dim userPhoto = ???? File.Delete(MapPath("~/UploadedImages/") & "\" & userPhoto) I need a value to set to the userPhoto variable which is supposed to be the title or name of the file. can any1 help please? thanx.
