salve,
ho questo problema.
ho uno script in vbs che non fa altro che zippare una cartella. eccolo
codice:
Option Explicit
Const FOF_CREATEPROGRESSDLG = &H0&
Dim sSourceFolder
Dim sArchiveFile
Dim oShell
Dim oZIP
Dim oSourceFolder
'Settaggio Variabili
sSourceFolder = "C:\database"
sArchiveFile = "C:\database_zip-"&Year(date())&Month(date())&Day(date())&".ZIP"
Dim oFSO
Dim oFile
Dim iFiles
Dim Fldr
Set oFSO = CreateObject( "Scripting.FileSystemObject" )
Set oFile = oFSO.OpenTextFile( sArchiveFile , 2, True )
oFile.Write "PK" & Chr(5) & Chr(6) & String( 18, Chr(0) )
oFile.Close
Set oFile = Nothing
Set oFSO = Nothing
iFiles = 0
With CreateObject("Shell.Application")
  'Copy the files to the compressed folder
  
 
   .NameSpace(sArchiveFile).CopyHere .NameSpace( sSourceFolder ).Items, FOF_CREATEPROGRESSDLG
  iFiles = iFiles + .NameSpace( sSourceFolder ).Items.Count
  'Keep script waiting until Compressing is done
  On Error Resume Next
  Do Until .NameSpace( sArchiveFile ).Items.Count = iFiles
   wScript.Sleep 1000
  Loop
  On Error GoTo 0
   
End With
lo script funziona, ma se nella cartella esiste una cartella vuota, si interrompe con questo errore:

File zip mancante o vuoto!

come posso risolvere il problema??
