ciao a tutti.
ho un piccolissimo problema.
ho fatto un programma che mi copia la cartella documenti o desktop a mia scelta tramite due checkbox, questa copia quando finisce io nn so se l'ha fatta o cè stato qualche errore, e quindi vorrei sapere il codice per verificare se la copia è stata fatta con successo.
ecco il codice del programma:
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 Const FOF_ALLOWUNDO = &H40&
Private Const FOF_CONFIRMMOUSE = &H2&
Private Const FOF_CREATEPROGRESSDLG = &H0&
Private Const FOF_FILESONLY = &H80&
Private Const FOF_MULTIDESTFILES = &H1&
Private Const FOF_NOCONFIRMATION = &H10&
Private Const FOF_NOCONFIRMMKDIR = &H200&
Private Const FOF_RENAMEONCOLLISION = &H8&
Private Const FOF_SILENT = &H4& 'Progress non visibile
Private Const FOF_SIMPLEPROGRESS = &H100& 'non visualizzare il nome del file
Private Const FOF_WANTMAPPINGHANDLE = &H20&
Private Type SHFILEOPSTRUCT
hwnd As Long
wFunc As Long

pTo As String

PercorsoScelto = Space$(512)

End If
End Function
Public Function CopyFile(Source As String, Dest As String, AskOverwrite, Visib) As Boolean
Dim lenFileop As Long

Dim fileop As SHFILEOPSTRUCT

ReDim foBuf(1 To lenFileop)
With fileop
.hwnd = Form1.hwnd
.wFunc = FO_COPY
.pFrom = Source & vbNullChar & vbNullChar & vbNullChar
.pTo = Dest & vbNullChar & vbNullChar
If AskOverwrite = False Then .fFlags = FOF_NOCONFIRMATION 'nn chiede la sovrascrittura
If Visib = False Then .fFlags = .fFlags Or FOF_SILENT 'invisibile
.lpszProgressTitle = "Copia " & Dest & vbNullChar & vbNullChar
End With
Call CopyMemory(foBuf(1), fileop, lenFileop)
Call CopyMemory(foBuf(19), foBuf(21), 12)
CopyFile = SHFileOperation(foBuf(1)) = 0
End Function
Private Sub about_Click()
Load about1
about1.Show
End Sub
Private Sub Command1_Click()
End
End Sub
Private Sub copia_Click()
If ckdo Then x = CopyFile("C:\Documents and Settings\" & txt & "\documenti", lbl, True, True)
If ckde Then x = CopyFile("C:\Documents and Settings\" & txt & "\desktop", lbl, True, True)
If Not x Then MsgBox "Errore l'utente specificato non esiste!", vbCritical, "Errore di copia"
End Sub
e in un pulsante sfoglia metto quest'altro codice:
lbl.Caption = SfogliaCartelle(Me.hwnd)
end sub
quale il codice da inserire per vedere se la copia e avvenuta con successo????
grazie molte e spero di essere stato chiaro.
