Event Handling in VB.Net + Late Binding

P: n/a
I Created Object A in the Object B. then I called a function of object
A from object B…
Like..

Public Class A

Public Event beforeSample()

Public Sub function_Sample()

RaiseEvent beforeSample()

‘’’’’’
‘’’’’’
‘’’’’’
End Function

End Class

Public Class B

Private WithEvents obj as new A

Private Function Main() as Boolean
‘’’’’’
‘’’’’
‘’’’’
‘’’’’
Obj. function_Sample()
‘’’’’
‘’’’’
‘’’’’
‘’’’’
End function
Private Sub obj_beforeSample() handle Obj.beforeSample

End Sub

End Class

So here I handle the event beforeSample in the Object B….!

The Problem is… How do I handle the events, if I create the object in
late bind method ?

means…

Public Class B

Private obj as Object

Private Function Main() as Boolean

‘’’’’’
‘’’’’’
‘’’’’’
obj = new A ‘late bind method

‘’’’’’
‘’’’’’
‘’’’’’
Obj. function_Sample()

End Function

End Class

Then How to handle the events of Object A ??
