Hi,

I am working with LeadTools 15.0 version. I am not able to get all the available Twain drivers on my system, when calling my scan application from web page. But when I run it separately I am getting all the drivers.

One driver is supplied by the Scanner vendor & the other driver might be from Twain for the Fujitsu 4120C2 Scanner as per my knowledge. The Twain supplied driver is not working properly but the driver supplied by scanner vendor works properly with all capabilities supported.

Please see the attached sample screen for details. Select Scanner 1.jpg file is when i run it separately and Select Scanner 2.jpg is when I call the sample application from Web Page. Please help out in solving this issue, should I have to add any more lead Tools References for solving this issue:

LeadTools Referenced used in my Scan Application:

Leadtools.dll , Leadtools.twain , Leadtools.Codecs , LeadTools.Fax , LeadTools.Tif

Leadtools.Twain , LeadTools.WinForms , LeadTools.ImageProcessing.Core

My application runs from C:\Inetpub\wwwroot\ path on my system when calling from Web Page

Regards

Sridhar

This dialog is generated from twain_32.dll found in your Windows directory. This DLL enumerates all available Twain Sources and presents them in this dialog. If a source is not listed when it should be there is nothing we can do about this.
