A insérer dans UserForm:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Private Sub ListBox1_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
    Call HookMouse(ListBox1, eSHEET)
End Sub
Private Sub ListBox1_LostFocus()
    UnHookMouse
End Sub
 
Private Sub ListBox1_Enter()
    Call HookMouse(Me.ListBox1, eUSERFORM, Me.Name)
End Sub
Private Sub ListBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    UnHookMouse
End Sub

Cela fonction qu'en 32bits

Si quelqu'un à un solution pour du 64bits je suis preneur!

Voilà!
J'espère que cela vous sera bien utile!

Bonjour Patrick,

Merci pour ta réponse, mais hélas ça ne fonctionne pas...
Néanmoins je ne me souvenais plus du LongPtr, MERCI Patrick pour ce rappel

Bonjour,

Je réactive ce sujet qui date un peu : j'ai essayé d'utiliser ce code pour un textbox en changeant juste le nom de la listebox par celui de ma textbox dans le code du userform, mais ça ne fait rien : pas de bug mais pas de changement au scroll...

Est-ce faisable ?
