How to 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.

Start Visual Studio.
Choose File->New->Project… from the menu.
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.
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.
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.
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"
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; 
```

Add the following class level variables::

Dim mediaWriter as MediaWriter 
Dim burnerDrive as MediaWriterDrive

MediaWriter mediaWriter; 
MediaWriterDrive burnerDrive;

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

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

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; 
}

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

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

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; 
}

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

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

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"); 
}

Add the following class function.

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

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

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.
