Web twain.

Sample Image - Web_Twain.jpg


Simply I want to use scanner in client side in DMS (Document Management System) web application. I have searched the Internet for solution but I found it very expensive for me so I decided to write a free one.


I found some articles in CodeProject like .NET TWAIN image scanner By NETMaster. That's nice. That is my goal:

  1. Rewrite NETMaster's application to be in one Windows form, make it automated and find way to deploy it in web page.
  2. Call this application from your web page.
  3. Upload the acquired image to server in simple way.

step 1:nop

step 2:You can use JavaScript to do it.

<input onclick="'file:///C:/TZTwain/TZTwain.exe',1);"
           type=button value=Scan>

But this code will not work with Windows XP sp2 Frown | :( So use this one:

<input onclick=runApp() type=button value="Scan XP sp2 users" name=button1>
<script language="javascript" type=text/javascript>
function runApp() 
  var shell = new ActiveXObject("");"c:\\tztwain\\tztwain.exe", 1, true); 

Step 3: You can use FTP or simply web service like me.

Sample App

  1. Configure testScan and FileUploadWS in IIS.
  2. FileUploadWS: Change save location.
    string filePath=Server.MapPath(@"..\testscan\upload\j2.jpg");
  3. TestScan: gives write permission to users (ASP.NET, IWAM and IUSR) at upload folder.
  4. Change web reference in testdotnettwain to localhost. Then build it and ZIP the exe file with winrar and make it sfx (with these options).
    Overwrite=1) then put the tztwain.exe in c:\inetpub\wwwroot\testScan.
