Take the following steps to start a project and to add some code that burns an ISO file, or a directory of files to disc

1. Start Visual Studio .NET.
2. Choose File->New->Project… from the menu.
3. In the New Project dialog box, choose either "Visual C# Projects" or "Visual Basic Projects" in the Projects Type List, and choose "Windows Application " in the Templates List.
4. Type the project name as "Burn ISO and CD_DVD Files" in the Project Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK.
5. In the "Solution Explorer" window, right-click on the "References" folder, and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to Leadtools For .NET "\LEAD Technologies\LEADTOOLS 16.5\Bin\DotNet\Win32 " folder and select the following DLLs:
   • Leadtools.dll
   • Leadtools.MediaWriter.dll
   Click the Select button and then press the OK button to add the above DLLs to the application.
6. Make sure Form1 is in design view. Go to the toolbox (View->Toolbox) and add the following controls to the form.
   • Textbox: Name = _txtInput
   • ComboBox: Name = _cmbDrives
   • Button: Name = _btnWrite, Text = "Write Data"
7. Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code ) and add the following lines at the beginning of the file:

   [Visual Basic]

   
   Imports Leadtools
   Imports Leadtools.MediaWriter
   

   [C#]

    
   using Leadtools;
   using Leadtools.MediaWriter;
   

8. Add the following class level variables::

   [Visual Basic]

   
   Dim mediaWriter as MediaWriter
   Dim burnerDrive as MediaWriterDrive
   

   [C#]

   
   MediaWriter mediaWriter;
   MediaWriterDrive burnerDrive;
   

9. Add an event handler to the Form1 Load event and add the following code:

   [Visual Basic]

   
   Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
      mediaWriter = New MediaWriter()
      _cmbDrives.Items.Clear()
      For Each drive As MediaWriterDrive In mediaWriter.Drives
         _cmbDrives.Items.Add(drive.Name)
      Next drive
      _cmbDrives.SelectedIndex = mediaWriter.CurrentDriveNumber + 1
   End Sub
   

   [C#]

   
   private void Form1_Load(object sender, System.EventArgs e)
   {
      mediaWriter = new MediaWriter();
      _cmbDrives.Items.Clear();
      foreach (MediaWriterDrive drive in mediaWriter.Drives)
      {
         _cmbDrives.Items.Add(drive.Name);
      }
      _cmbDrives.SelectedIndex = mediaWriter.CurrentDriveNumber + 1;
   }
   

10. Add an event handler to the _cmbDrives SelectedIndexChanged event and add the following code:

    [Visual Basic]

    
    Private Sub _cmbDrives_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
       mediaWriter.CurrentDriveNumber = _cmbDrives.SelectedIndex - 1
       If Not burnerDrive Is Nothing Then
          burnerDrive.OnDeviceEvent -= burnerDrive_OnDeviceEvent
       End If
       burnerDrive = mediaWriter.CurrentDrive
       'Only add device event for valid drives
       If burnerDrive.DriveNumber <> -1 Then
          AddHandler burnerDrive.OnDeviceEvent, AddressOf Of MediaWriterDevNotifyEventArgs
       End If
       _btnWrite.Enabled = burnerDrive.Writeable
    End Sub
    

    [C#]

    
    private void _cmbDrives_SelectedIndexChanged(object sender, System.EventArgs e)
    {
       mediaWriter.CurrentDriveNumber = _cmbDrives.SelectedIndex - 1;
       if (burnerDrive != null)
          burnerDrive.OnDeviceEvent -= burnerDrive_OnDeviceEvent; 
       burnerDrive = mediaWriter.CurrentDrive;
       //Only add device event for valid drives
       if (burnerDrive.DriveNumber != -1)
          burnerDrive.OnDeviceEvent += new EventHandler<MediaWriterDevNotifyEventArgs>(burnerDrive_OnDeviceEvent);
       _btnWrite.Enabled = burnerDrive.Writeable;
    }
    

11. Add an event handler to the _btnWrite Click event and add the following code:

    [Visual Basic]

    
    Private void Function btnWrite_Click(ByVal sender As Object, ByVal e As System.EventArgs) As _
       If String.IsNullOrEmpty(_txtInput.Text) Then
          MessageBox.Show("You must choose an input file" & Constants.vbFormFeed & "older")
          Return
       End If
       Dim burnDisc As MediaWriterDisc = burnerDrive.CreateDisc()
       burnDisc.SourcePathName = _txtInput.Text
       burnDisc.VolumeName = "LEAD Media"
       burnerDrive.BurnDisc(burnDisc)
       Me.Text = "Writing"
       Do While burnerDrive.State = MediaWriterState.StateWriting
          'Loop until complete
          Application.DoEvents()
       Loop
       this.Text = "Complete";
       MessageBox.Show("Complete")
    End Function
    

    [C#]

    
    private void _ btnWrite_Click(object sender, System.EventArgs e)
    {
       if (String.IsNullOrEmpty(_txtInput.Text))
       {
          MessageBox.Show("You must choose an input file\folder");
          return;
       }
       MediaWriterDisc burnDisc = burnerDrive.CreateDisc();
       burnDisc.SourcePathName = _txtInput.Text;
       burnDisc.VolumeName = "LEAD Media";
       burnerDrive.BurnDisc(burnDisc);
       this.Text = "Writing";
       while (burnerDrive.State == MediaWriterState.StateWriting)
       {
          //Loop until complete
          Application.DoEvents();
       }
       this.Text = "Complete";
       MessageBox.Show("Complete");
    }
    

12. Add the following class function.

    [Visual Basic]

    
    Private Sub burnerDrive_OnDeviceEvent(ByVal sender As Object, ByVal e As MediaWriterDevNotifyEventArgs)
       _btnWrite.Enabled = burnerDrive.Writeable
    End Sub
    

    [C#]

    
    void burnerDrive_OnDeviceEvent(object sender, MediaWriterDevNotifyEventArgs e)
    {
       _btnWrite.Enabled = burnerDrive.Writeable;
    }
    

13. Build, and Run the program to test it.

    Select your burner from the drives list, fill the textbox with the path to a valid ISO image or directory of files, and click the "Write" button.
