Code:
option Explicit
'Constantes
private Const BIF_RETURNONLYFSDIRS = &H1 'Uniquement des répertoire
private Const BIF_DONTGOBELOWDOMAIN = &H2 'Domaine globale intredit
private Const BIF_STATUSTEXT = &H4 'Zone de saisie autorisée
private Const BIF_RETURNFSANCESTORS = &H8
private Const BIF_EDITBOX = &H10 'Zone de saisie autorisée
private Const BIF_VALIDATE = &H20 'insist on valid result (or CANCEL)
private Const BIF_BROWSEFORCOMPUTER = &H1000 'Uniquement des PCs.
private Const BIF_BROWSEFORPRINTER = &H2000 'Uniquement des imprimantes
private Const BIF_BROWSEINCLUDEFILES = &H4000 'Browsing for Everything
private Const MAX_PATH = 260
'Types
private Type T_BROWSEINFO
HwndOwner as Long
pIDLRoot as Long
pszDisplayName as Long
lpszTitle as Long
ulFlags as Long
lpfnCallback as Long
lParam as Long
iImage as Long
End Type
'Fonctions API Windows

byval lpBuffer as string) as Long

public Function BrowseFolder(byval HwndOwner as Long, byref Titre as string) as string
Dim lpIDList as Long
Dim sBuffer as string
Dim BrowseInfo as T_BROWSEINFO
'Initialise l'affichage
BrowseFolder = ""
With BrowseInfo
.HwndOwner = HwndOwner
.lpszTitle = lstrcat(Titre, "")
.ulFlags = BIF_RETURNONLYFSDIRS
End With
'Affiche la boite de dialogue
lpIDList = SHBrowseForFolder(BrowseInfo)
'Récupère le répertoire sélectionné
If (lpIDList) then
sBuffer = Space(MAX_PATH)
SHGetPathFromIDList lpIDList, sBuffer
sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)
BrowseFolder = sBuffer
End If
End Function
