Hello Everyone,
I am building a web application that needs to have some web pages with the ability to possibly integrate with a scanner, read the scanned document, display it on the web page and then upload it in a suitable format on the server. So I want to know what could I need to do that. Do I require an external API or a third party dll or something else. I would be really grateful if anyone of you could atleast give me a few links to the required resources. Thanks a lot

Hi Krunal,

Thanks for those links. These links have good information about how to scan in a windows application. However I need to be able to scan through my asp.net web pages.

Given below are some of the questions that I have about the links that you posted.

1. In the first link (http://www.codeproject.com/KB/aspnet/Web_Twain.aspx) the author is trying to run an executable through a javascript code. If I have to do this then I will have to rely on every client machine to have that exe in the same path. Also the author mentions something about deploying the NetMasters .Net Twain Image scanner which is a windows application in a web page which is something I did not understand.

2. The other link (http://www.dynamsoft.com/Products/WebTWAIN_Overview.aspx) of course looks like a solution to me for web scanning, but I would like to check out if there is any other way where I won't have to do any purchasing.

I would really appreciate it if you could provide me a solution to my above questions.

Hi Guys,

I finally found out what I was looking for. You can find the sample code in the following link
http://www.chestysoft.com/ximage/twainupload.asp. This sample makes use of an ActiveX object called csXImage, which must be installed on every client machine. This ActiveX object has methods to select a TWAIN compliant scanning device, aquire the image, and upload the image to a server. Additionally it also has methods to crop the scanned image, rotate it etc.

Thanks a lot.
