كود :

Imports System.Management
Imports Microsoft.Win32

Public Class Form1
    Dim WithEvents pluggedInWatcher As ManagementEventWatcher
    Dim WithEvents pluggedOutWatcher As ManagementEventWatcher
    Dim pluggedInQuery As WqlEventQuery
    Dim pluggedOutQuery As WqlEventQuery

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Try
            pluggedInQuery = New WqlEventQuery
            pluggedInQuery.QueryString = "SELECT * FROM Win32_VolumeChangeEvent WHERE EventType = 2"
            pluggedInWatcher = New ManagementEventWatcher(pluggedInQuery)
            pluggedInWatcher.Start()

            pluggedOutQuery = New WqlEventQuery
            pluggedOutQuery.QueryString = "SELECT * FROM Win32_VolumeChangeEvent WHERE EventType = 3"
            pluggedOutWatcher = New ManagementEventWatcher(pluggedOutQuery)
            pluggedOutWatcher.Start()
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

    Private Sub pluggedInWatcher_EventArrived(sender As Object, e As EventArrivedEventArgs) Handles pluggedInWatcher.EventArrived
        MsgBox("Plugged In")
    End Sub

    Private Sub pluggedOutWatcher_EventArrived(sender As Object, e As EventArrivedEventArgs) Handles pluggedOutWatcher.EventArrived
        MsgBox("Plugged Out")
    End Sub
End Class

ملاحظة : الكود يعمل مع اصدار فريم وورك 4 او اعلى

لم يقم بالغرض
