Question

I have a function that is called when a file is modified in a folder. This function updates the items of a listview which is stored in the UI.

Here is the function :

Private Sub FileChangeNotify()
    Try
        LstMoulures.Items.Refresh()
    Catch ex As Exception
        MsgBox(Ex.exception)
    End Try

End Sub

Here is the error: “Le thread appelant ne peut pas accéder à cet objet parce qu’un autre thread en est propriétaire.” (Translation : The calling thread cannot access this object because it is owned by another thread)

Thanks.

End Sub
