(Q) Ok, je sais comment utiliser la fonction API " GetOpenFileName", mais je
ne suis intéressé qu'aux répertoires. Comment puis-je faire, à partir du code?
(A) Couper-coller le code suivant dans un nouveau module.
Private Type BROWSEINFO
hOwner As Long
pidlRoot As Long
pszDisplayName As String
lpszTitle As String
ulFlags As Long
lpfn As Long
lParam As Long
iImage As Long
End Type
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" Alias _
"SHGetPathFromIDListA" (ByVal pidl As Long, _
ByVal pszPath As String) As Long
Private Declare Function SHBrowseForFolder Lib "shell32.dll" Alias _
"SHBrowseForFolderA" (lpBrowseInfo As BROWSEINFO) _
As Long
Private Const BIF_RETURNONLYFSDIRS = &H1
Public Function BrowseFolder(szDialogTitle As String) As String
Dim X As Long, bi As BROWSEINFO, dwIList As Long
Dim szPath As String, wPos As Integer
With bi
.hOwner = hWndAccessApp
.lpszTitle = szDialogTitle
.ulFlags = BIF_RETURNONLYFSDIRS
End With
dwIList = SHBrowseForFolder(bi)
szPath = Space$(512)
X = SHGetPathFromIDList(ByVal dwIList, ByVal szPath)
If X Then
wPos = InStr(szPath, Chr(0))
BrowseFolder = Left$(szPath, wPos - 1)
Else
BrowseFolder = ""
End If
End Function
Sauvegarder le module sous un nom qui ne soit pas celui d'une fonction. Inspirez vous
de l'exemple ci-dessous pour appeler cette fonction.
Dim strFolderName as string
strFolderName = BrowseFolder("Quel répertoire désirez-vous utiliser?")
