Use the MediaWriter to burn ISO files and DVD images

Perform 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.

2. Choose File->New->Project… from the menu.

3. In the New Project dialog box, choose either "Visual C# Projects" or "VB Projects" in the Projects Type List, and choose "Windows Form Application" in the Templates List.

4. Type the project name as "Burn ISO and CD_DVD Files" in the Project Name field, and then click OK. If desired, type a new location for your project or click the Browse button, and navigate to a new location. Click OK.

5. In the "Solution Explorer" window, right-click the "References" folder, and choose "Add Reference…" from the context menu. In the "Add Reference" dialog box, click the ".NET" tab and navigate to the LEADTOOLS For .NET ("<LEADTOOLS_INSTALLDIR>\Bin\Dotnet4\Win32") folder and select the following DLLs:

   • Leadtools.dll
   • Leadtools.MediaWriter.dll

   With the DLLs selected, click OK 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 and then choose View Code ) and add the following lines to the beginning of the file:

   vb 
   Imports Leadtools 
   Imports Leadtools.MediaWriter 

   C#

         
   using Leadtools; 
   using Leadtools.MediaWriter; 

8. Add the following class level variables::

   vb 
   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:

   vb 
   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:

    vb 
    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:

    vb 
    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.

    vb 
    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.
