Implementation

  • The application defines the following methods:
    • ScanText gets as an argument the data obtained from IdHTTP.TIdHTTP.Get. The method calls AddItem to populate the TListBox with the audio files from the URL.
    • GetTagValue provides the URL to the videos from the raw data obtained in IdHTTP.TIdHTTP.Get. The URL is the item that uses ScanText to populate the list of available audio files.
    • IsItemCorrect is used in ScanText to check ig the item is an mp3 audio file.
    • AddItem adds the items to the TListBox.
  • The application defines the following significant controls:
    • Button2, the Scan button, executes Button2Click when clicked.
    • Button1, the Start button, executes Button1Click when clicked.
    • Button3, the Stop/Pause button, executes Button3Click when clicked.
    • Edit1 sets the URL to get the mp3 files from the Internet.
