Hi all

I got a new scanner and now this code works. 
It's a Lexmark X6170 all-in-one machine which has the advantage that
you get a scanner with document feeder at a very low cost - otherwise
"document scanners" tend to be quite expensive. This one can fax and
print too, but who cares.

It features a WIA driver and that does the trick.

Hi all

I'm having trouble with this. 

I have a scanner installed which works fine with the GUI and MS
Document Imaging etc. of Office 2003.
However, my code - taken from the sample around - will not count my
scanner.
No errors, just no count.
What is missing?

  Dim CommonDialog1 As Object
  Dim DeviceManager1 As Object
  Dim i As Integer

  Set DeviceManager1 = CreateObject("WIA.DeviceManager")
  Set CommonDialog1 = CreateObject("WIA.CommonDialog")

  For i = 1 To DeviceManager1.DeviceInfos.Count
    MsgBox DeviceManager1.DeviceInfos(i).Properties("Name").Value &
vbCrLf & _
      "(" & DeviceManager1.DeviceInfos(i).DeviceID & ")"
  Next

WiaAut.dll is even referenced correctly. I obtained it here:

The scanner is Agfa SnapScan 1236 via SCSI, old and a bit slow but OK.
OS is WinXP SP2.
