Hola,con ese control no se puede parece,pero desde codigo podes sacarlos algo asi: Private Sub Form_Load() Dim Ocultos As String Ocultos = Dir("c:\", vbDirectory + vbHidden) Do While Ocultos <> "" Debug.Print Ocultos Ocultos = Dir Loop End Sub EDIT:Aca esta Option Explicit
Private Const MAX_PATH = 260 Private Type FILETIME dwLowDateTime As Long dwHighDateTime As Long End Type Private Type WIN32_FIND_DATA dwFileAttributes As Long ftCreationTime As FILETIME ftLastAccessTime As FILETIME ftLastWriteTime As FILETIME nFileSizeHigh As Long nFileSizeLow As Long dwReserved0 As Long dwReserved1 As Long cFileName As String * MAX_PATH cAlternate As String * 14 End Type
Private Declare Function FindFirstFile Lib "kernel32" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN32_FIND_DATA) As Long Private Declare Function FindNextFile Lib "kernel32" Alias "FindNextFileA" (ByVal hFindFile As Long, lpFindFileData As WIN32_FIND_DATA) As Long Private Declare Function FindClose Lib "kernel32" (ByVal hFindFile As Long) As Long
Private Const LB_GETCOUNT = &H18B Private Const LB_INSERTSTRING = &H181 Private Const LB_ERR = (-1)
Private Const FILE_ATTRIBUTE_HIDDEN = &H2 Private Const FILE_ATTRIBUTE_SYSTEM = &H4 Private Const FILE_ATTRIBUTE_DIRECTORY = &H10
Private Declare Function SendMessageString Lib "user32" Alias "SendMessageA" _ (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _ ByVal lParam As String) As Long Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" _ (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _ lParam As Any) As Long
Private Sub ShowHiddenDirectories(DirCtrl As DirListBox, Optional bShowSystem As Boolean) Dim res As Long Dim sF As String, sDirPath Dim FData As WIN32_FIND_DATA Dim fHand As Long, i As Long Dim level As Long Dim StillOK As Long Const HIDDEN_DIRECTORY = FILE_ATTRIBUTE_DIRECTORY Or FILE_ATTRIBUTE_HIDDEN sDirPath = DirCtrl.Path If Right$(sDirPath, 1) <> "\" Then sDirPath = sDirPath & "\" res = SendMessage(DirCtrl.hwnd, LB_GETCOUNT, 0, 0) If res = LB_ERR Then Exit Sub level = res - DirCtrl.ListCount fHand = FindFirstFile(sDirPath & "*", FData) StillOK = fHand Do While StillOK > 0 If (FData.dwFileAttributes And HIDDEN_DIRECTORY) >= HIDDEN_DIRECTORY Then If bShowSystem Or ((FData.dwFileAttributes And FILE_ATTRIBUTE_SYSTEM) = 0) Then sF = CutRightAt(FData.cFileName) If sF <> "." And sF <> ".." Then i = DirCtrl.ListCount Do If i > 0 Then res = StrComp(sF, Right(DirCtrl.List(i - 1), Len(DirCtrl.List(i - 1)) - Len(sDirPath)), vbTextCompare) If res >= 0 Then If res Then res = SendMessageString(DirCtrl.hwnd, LB_INSERTSTRING, i + level, sF) Exit Do End If Else If i = 0 Then res = SendMessageString(DirCtrl.hwnd, LB_INSERTSTRING, i + level, sF) End If i = i - 1 Loop While i >= 0 End If End If End If
StillOK = FindNextFile(fHand, FData) Loop
fHand = FindClose(fHand) End Sub
Private Function CutRightAt(NormString As String, Optional ascii As Long = 0) As String Dim i As Long i = InStr(1, NormString, Chr(ascii), vbBinaryCompare) If i Then CutRightAt = Left(NormString, i - 1) Else CutRightAt = NormString End If End Function
Private Sub Dir1_Change() ShowHiddenDirectories Dir1, True End Sub
saludos.
