Merci d'avance.

Avec les fonctions GetSetting et SaveSetting de VB.

Bonjour,

je voudrais lire une clé du registre et en afficher la
valeur dans un champs texte.

Comment puis je faire?

Merci d'avance.

Tu peux aussi jeter un oeil sur ma classe CRegistry() qui wrap (de façon
primaire) l'utilisation de ces APIs..

Ex :
'***
' Obtiens le nom du thème présentement utilisé sur XP
' Module1
Option Explicit

Private Sub Main()

Dim reg As CRegistry
Set reg = New CRegistry

Select Case reg.GetValue( _
rkcCurrentUser, _
"SoftwareMicrosoftWindowsCurrentVersionThemeManager", _
"ColorName")

Case "NormalColor"
Debug.Print "Default (blue)"

Case "HomeStead"
Debug.Print "Olive Green"

Case "Metallic"
Debug.Print "Silver"

Case Else
Debug.Print "Unknown Color Scheme"

End Select

End Sub
