Map Basic
Bonjour,
Y at 'il une fonction sous map basic capable d'ouvrir une fenetre de type choix d'un repertoire .
Attention je ne parle pas d'un FileOpenDlgou bien d'un FileSaveAsDlg, qui permettent de pointer sur un fichier de type defini, mais d'un repertoire uniquement.
Merci

Re: Map Basic
Non, en VB, j'utilise l'API SHBrowseForFolder mais je n'ai jamais essaye depuis MapBasic.
Si ca vous interesse, voici ci-dessous un module VB qui utilise cette API

Private Const BIF_STATUSTEXT = &H4&
Private Const BIF_RETURNONLYFSDIRS = 1
Private Const BIF_DONTGOBELOWDOMAIN = 2
Private Const MAX_PATH = 260
Private Const WM_USER = &H400
Private Const BFFM_INITIALIZED = 1
Private Const BFFM_SELCHANGED = 2
Private Const BFFM_SETSTATUSTEXT = (WM_USER + 100)
Private Const BFFM_SETSELECTION = (WM_USER + 102)

lpIDList = SHBrowseForFolder(tBrowseInfo)

sBuffer = Space(MAX_PATH)
SHGetPathFromIDList lpIDList, sBuffer

End Function

End If
End Select

End Function

End Function
