I have to use scanner on Internet site web page. As far as I know not Flash nor Silverlight is capable to communicate with such hardware nowadays. It looks like there is no alternative to Active-X at present for such operation (correct me if I'm wrong).
我必须在互联网站点网页上使用扫描仪。据我所知，Flash和Silverlight现在无法与这些硬件进行通信。看起来目前没有Active-X替代此类操作（如果我错了，请纠正我）。
After image is scanned I have to send it to server via HTTPS and wait for processing result.
扫描图像后，我必须通过HTTPS将其发送到服务器并等待处理结果。
I have some alternatives here:
我有一些替代方案：
- Start ajax polling with regular interval
- 定期启动ajax轮询
- Put polling functionality straight into active-x component
- 将轮询功能直接放入active-x组件中
What approach would you personally preffer?
你个人会采取什么方法？
Is it possible to establish event mechanism for Active-X approach (when server pushes result back to a web-page?). Will events work for javascript/ajax approach?
是否可以为Active-X方法建立事件机制（当服务器将结果推回到网页时？）。事件是否适用于javascript / ajax方法？
Thank you in advance!
先谢谢你！

Have the client scan and upload a file. That's how it's done these days. Scanning software is a part of OS - at least, in Windows and MacOS it is.
让客户端扫描并上传文件。这就是现在这样做的方式。扫描软件是操作系统的一部分 - 至少在Windows和MacOS中是这样。
With an ActiveX object, it will become a support nightmare. Also, think of all the Firefox/Chrome/Opera/Non-Windows users out there.
使用ActiveX对象，它将成为支持噩梦。另外，想想那里的所有Firefox / Chrome / Opera /非Windows用户。
Also, I vaguely recall scanner support will be added in HTML5.
此外，我依旧回忆起HTML5中将添加扫描仪支持。
