Hi
Here is the detailed explanation of 3rd point
lets create a DotNet Assembly with class CEmp that exposes properties (FirstName,
LastName, DOB) and raises an event (Senior). Raising an event from DotNet Component
and consuming it in COM component is done by defining event sink interface in managed
code and then apply the ComSourceInterfacesAttribute to connect the event sink
interface to the managed class.
VB.Net CEmp class code
Imports System
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
<InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)> _
Public Interface evtSenior
Sub Senior()
End Interface
<ComSourceInterfacesAttribute("evtSenior")> _
Public Class CEmp
Private mstrFirstName As String
Private mstrLastName As String
Private mdtDOB As Date
Public Event Senior()
Public Property FirstName() As String
Get
FirstName = mstrFirstName
End Get
Set(ByVal Value As String)
mstrFirstName = Value
End Set
End Property
Public Property LastName() As String
Get
LastName = mstrLastName
End Get
Set(ByVal Value As String)
mstrLastName = Value
End Set
End Property
Public Property DOB() As Date
Get
DOB = mdtDOB
End Get
Set(ByVal Value As Date)
mdtDOB = Value
If DateDiff(DateInterval.Year, Value, Now) > 60 Then
RaiseEvent Senior()
End If
End Set
End Property
End Class
