The problem is that I don't attach anything.
Try this test code pls, so I will be sure that I am not crazy ^^...
Public Class CMyClass
Inherits Object
Private fPropertyOne As String
Private fPropertyTwo As Integer
Public Event OnSomeEvent(ByRef vSender As Object)
End Class
Private Sub btn1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btn1.Click
Dim i As Integer
For i = 0 To 1000
Dim oEl As New CMyClass()
Console.WriteLine("element created " &
GC.GetTotalMemory(True))
oEl = nothing
Console.WriteLine("element after destroying " &
GC.GetTotalMemory(True))
Next
End Sub
End Class
You will find memory growing after any creation. If you cancel event
declaration, you will find that memory get back to the original size
after any creation.
To solve now I try to delegate to a specific object the events, but
it's heavy refactoring and not solve the original problem.
I'm a delphi developer and in Delphi events are property destroyed
when object get free.
I don't understand this way to treat events...
Thank you!
