Hi,
Thank you for the prompt reply to my previous post. I hv another question for you. While scanning, I want all the pages to go to a single file untill user says not to. Following would be the algorithm for it-
1) open default scanner
2) start multipage file
3) scan and save all the pages in the feeder
4) ask the user whether he want to scan more pages.
5) if yes..then go back to step 1 else close the multipage file and scanner.
The multipage files could be pdf or tiff.
Thank you
Charu Vasudev

Hi,
Here is a vb6 sample to acquire image from document feeder & asking to the user to acquire other pages when the feeder is empty:
Code: Select all
Dim nImageID As Long
Dim bContinue As Boolean
bContinue = True
Imaging1.SetLicenseNumber ("XXX")
If Imaging1.TwainOpenDefaultSource() Then
Imaging1.TwainSetAutoFeed (True) 'Set AutoFeed Enabled
Imaging1.TwainSetAutoScan (True) 'To achieve the maximum scanning rate
Imaging1.TwainSetCurrentResolution (300)
Imaging1.TwainSetCurrentPixelType (TWPT_RGB) 'RGB
Imaging1.TwainSetCurrentBitDepth (8) ' 24 bpp
Imaging1.TwainPdfStart ("output.pdf")
Imaging1.TwainDisableAutoSourceClose (True)
Do
nImageID = Imaging1.TwainAcquireToGdPictureImage(Me.hWnd)
If nImageID <> 0 Then
Call Imaging1.TwainAddGdPictureImageToPdf(nImageID)
Imaging1.CloseImage (nImageID)
End If
If Imaging1.TwainGetState <= 5 Then
If MsgBox("Do you want to scan other image ?", vbYesNo, "") <> 6 Then
bContinue = False
End If
End If
Loop While bContinue
Imaging1.TwainPdfStop
Call Imaging1.TwainCloseSource
MsgBox "Done !"
Else
MsgBox "can't open default source, twain state is: " & Trim(Str(Imaging1.TwainGetState))
End If
Best regards,
Loïc

Hi,
I tried to replicate the situation using:
Code: Select all
oGdPictureImaging.TwainSetAutoSourceClose(false);
But the scanner prompt keeps closing...
Any help would be appreciated..
