CD/DVDROM Eject in VB.NET

Submitted by donbermoy on Tuesday, April 8, 2014 - 19:03.

In this tutorial, we will create a program that can eject the CD/DVD-ROM of a laptop or desktop computer that can also view the drive for this ROM. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Right Click ToolBox, click Choose Items, in the Com Components Tab, check "Windows Media Player" and then click Ok. 3. Next, add only one Button named Button1 and labeled it as "Eject". Insert a combobox named ComboBox1 for displaying the drive of the cdrom. You must design your interface like this: output

4. Declare this global variable in your code module.

    Dim varCDrom As New WMPLib.WindowsMediaPlayer
    Dim totalCDDrive As Integer
    Dim i As Integer

We just used the WindowsMediaPlayer library to open the cdrom collection which hold the varCDrom variable. 5. In your Form_Load, copy the code below. This will show all the drives for CDROM to be displayed in the combobox.

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        totalCDDrive = 0
        i = 0
        totalCDDrive = varCDrom.cdromCollection.count
        If (totalCDDrive >= 1) Then
            For i = 0 To (totalCDDrive - 1)
                ComboBox1.Items.Add(varCDrom.cdromCollection.Item(i).driveSpecifier)
            Next
            ComboBox1.Text = ComboBox1.Items.Item(0)
        End If
 
    End Sub

We initialized first the totalCDDrive variable and i variable to 0. Then the totalCDDrive variable will be equal to number of cdrom drives. Then the cdrom drive will be displayed in the combobox. 6. Put this code in your Button1_Click. This will trigger to eject the drive you have chosen in the combobox.

If Not (ComboBox1.Text = "") Then
            varCDrom.cdromCollection.Item(ComboBox1.SelectedIndex).eject()
        End If

If the combobox is not empty, then the selected index cdrom drive in combobox is ejected as we have the property of cdromCollection has eject property.
