I have a asp.net app, in the page there is a scan activex which could scan
and save a jpg file in client harddisk.
How could we access and display this jpg file on the fly using js in the
client IE?
Thanks,

Hi Billy,
As for web page and javascript, it is not allowed to access client
computer's file system. Actually, both IE7 and firefox restrict local image
file viewing. So far based on my research, some workarounds availables are:
1. Upload image to server-side so that we can use script to
programmtically display an html <imgvia a server-side url
2. Integrate the image displaying functionality into the ActiveX control.
That means use ActiveX control to load local file image and display it.
Maybe you can add another ActiveX control on the page to do the work.
BTW, I found that silverlight 2 seems support local image loading.

Thanks for your reply billy,
As for image activex control, I'm not sure about those commercial ones. If
you want to build a simple one on the fly, you can refer to the following
examples on code project which maybe helpful: http://www.codeproject.com/KB/openGL/ntgraph3d_atl.aspx http://www.codeproject.com/KB/atl/hktbcatl1.aspx https://secure.codeproject.com/KB/CO...fid=42134&df=9

If I take an earlier version of Access and link the image, it puts the
