    prevent data duplication

    i am creating a program for a school project. I need to write a code that would prevent the user from lending out the same video to one member. The program's for a video store.


    Thank you.

    Time to get out the old mark I documentation device (Pencil and paper) and have a look at your database design while your at it as this problem can be solved with your database design and a check against it...



    Good Luck

      You have to explain your frontend and backend name and versions. Below is simple data check.
      You can check with video taken time and video file name.

          Bytes has a policy regarding assisting students with their homework.

          The short version is that the volunteers here can't help you with schoolwork.
          A) We don't know what material you have and have not learned in class.
          B) We don't know the guidelines you must follow.
          C) In the long run giving you the answers actually short changes your education.

          Hint 1: Try hitting Google with terms of your programming language and primary terms of what you want to do. For example "C# custom events" or "VB datagrid Excel". I've found this to be a very effective tool.
          Hint 2: Your text book
          Hint 3: Your instructor
          Hint 4: Posting guidelines regarding homework assignments.
