faire un copier coller d'un item dans une listview

Salut Eric ! :O)

La classe ClipBoard supporte automatiquement l'ajout d'objet Serializable.

Voici un exemple.
'***
Option Explicit On

Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Code généré par le Concepteur Windows Form "

Public Sub New()
MyBase.New()

'Cet appel est requis par le Concepteur Windows Form.
InitializeComponent()

'Ajoutez une initialisation quelconque après l'appel
InitializeComponent()

End Sub

'La méthode substituée Dispose du formulaire pour nettoyer la liste des
composants.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

'Requis par le Concepteur Windows Form
Private components As System.ComponentModel.IContainer

'REMARQUE : la procédure suivante est requise par le Concepteur Windows
Form
'Elle peut être modifiée en utilisant le Concepteur Windows Form.
'Ne la modifiez pas en utilisant l'éditeur de code.
