EZTwainX - Uploading
See also: getting started, methods, deployment
To upload an image or set of images from the EZTwainX control to a web server, you have these broad alternatives:
1. Use the built-in EZTwainX upload methods.
This is best for the simplest case, where your upload can be synchronous, the server requires no authentication or minimal authentication, and there is no proxy between the client and the server.
2. Use the built-in EZTwainX upload methods and disable authentication for the upload script.
This can work for synchronous upload to an IIS server that is using authentication such as NTLM. You disable authentication on the page that receives the upload, by setting that one page to "anonymous authorization", or better yet placing the upload script in a subfolder and setting anonymous authorization for that folder. If you then include and validate the session ID in the upload, the upload page is still protected from unauthorized use.
3. Use javascript code on your web page to implement a conventional multipart-form-submit with HTTP-POST.
We have an example page here. The (very rough!) server code is here.
4. Use a platform-specific or 3rd party file-upload component.
If you are using ASP.NET for example, there are many file-upload components available.
