Thank You,

Dim intCompletionCode As Integer
   
Private Sub Command1_Click()
   TWAIN_SetHideUI (1)  ' request no UI
   If (TWAIN_GetDuplexSupport() = 0) Then
       MsgBox (" nO DUPLEX")
       End
   Else
       TWAIN_SelectFeeder (1)
       TWAIN_EnableDuplex (1)
   End If
   
   intCompletionCode = TWAIN_AcquireToFilename(0, "C:\Scanning\Yes.tif")
   Select Case intCompletionCode:
      Case 0
         MsgBox (" Success !!! ")
      Case -1
         MsgBox ("The Acquire failed")
      Case -2
         MsgBox ("File Open Error (Invalid path or name, or access denied)")
      Case -3
         MsgBox ("Invalid DIB, or image incompatible with file format, or ...")
      Case -4
         MsgBox ("Writing Failed, possibly output device is full.")
      Case -10
         MsgBox ("User cancelled File Save Dialog")
      Case Else
         MsgBox ("Unknown Error: " & intCompletionCode)
   End Select
   If (TWAIN_UnloadSourceManager() <> 0) Then
       MsgBox ("eRROR")
   End If
End Sub

Private Sub Form_Load()
   If (TWAIN_OpenSource("FUJITSU fi-4120Cdj") <> 1) Then
       MsgBox ("Could not Open Scanner, Exiting ... ")
       End
   End If
End Sub
