Hey guys.
Is it possible to manipulate the order of execution from the "Raise Event" function of Custom events? It could be done by adding each "handler" to a collection and executing them asynchronously but I couldn't manage to do it myself.
Here is how my code looks like:
Say I need to execute Run3 then Run2 then Run1 without changing the order of the Add Handlers.
Thank you in advance,
Dave.

Code:
Class MainWindow
Private WithEvents EventTest As New Events
Private Sub Form_load(ByVal sender As Object, e As EventArgs) Handles Me.Loaded
AddHandler EventTest.Go, AddressOf Run1
AddHandler EventTest.Go, AddressOf Run2
AddHandler EventTest.Go, AddressOf Run3
End Sub
Private Sub Run1()
Debug.Print("1")
End Sub
Private Sub Run2()
Debug.Print("2")
End Sub
Private Sub Run3()
Debug.Print("3")
End Sub
Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
EventTest.ExecuteEvent()
End Sub
End Class
Public Class Events
Public Delegate Sub GoEventHandler()
Private mGoHandlers As GoEventHandler
Public Sub ExecuteEvent()
RaiseEvent Go()
End Sub
Public Custom Event Go As GoEventHandler
AddHandler(value As GoEventHandler)
mGoHandlers = CType([Delegate].Combine(mGoHandlers, value), GoEventHandler)
End AddHandler
RemoveHandler(value As GoEventHandler)
mGoHandlers = CType([Delegate].Remove(mGoHandlers, value), GoEventHandler)
End RemoveHandler
RaiseEvent()
If mGoHandlers IsNot Nothing Then
mGoHandlers.Invoke()
End If
End RaiseEvent
End Event
End ClassThank you in advance,
Dave.
