Public Class WebForm1

    Inherits System.Web.UI.Page

#Region " Web Form Designer Generated Code "

    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()

    End Sub
    Protected WithEvents div_news As System.Web.UI.HtmlControls.HtmlGenericControl

    Private designerPlaceholderDeclaration As System.Object

    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        InitializeComponent()
    End Sub


#End Region


    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim mypop As Pop = Nothing

        mypop = New Pop("exchg_srv", "habashara", "doggpound")
        mypop.Port = 110
        mypop.Connect()
        MsgBox(mypop.GetUid(1))
        mypop.Disconnect()

End Class

عند التنفيذ يظهر رسالة كالتالي

Access to the registry key HKEY_CLASSES_ROOT\CLSID is denied.
