Hi everybody,

Simple question : Inside a class that has a shared method, how to raise an
event on a given instance of this class from the shared method ?

Just pass the instance variable to the shared method. Here's a working
example:

Module Module1

    Sub Main()
        Dim c As New YourClass
        YourClass.ChangeName(c, "funny pants")
        Console.WriteLine(c.Name)
        Console.Read()
    End Sub

End Module

Public Class YourClass

    Private m_Name As String

    Public Shared Sub ChangeName(ByVal c As YourClass, ByVal newName As
String)
        c.Name = newName
    End Sub

    Public Property Name() As String
        Get
            Return m_Name
        End Get
        Set(ByVal value As String)
            m_Name = value
        End Set
    End Property

End Class

Thanks,

In order to do that you need a reference to an instance of the class. If
you implement the event using the .NET event pattern you can call the
corresponding protected 'On<event name>' method to raise the event.
