I am trying to give user option to upload file in an application. So user can browse the file using upload control and can

1- upload the file to the database
2- If the file is sensitive an duser don't want to upload it to the database , s/he can upload the full path of the file to the database which should then open by clicking the path link

1 is easy to do and I have already implemented it. But with 2 there are few issues:

a- getting the full path (there is no standard among browsers for this i.e. it shows
1- full path in IE9
2- only file name in firefox
3- C:\FakePath\ and file name in chrome.
)

b- How to open it from a webpage

As far as I have researched it is not possible to get the full path due to security issues perceived by the browsers. Also opening the local file from http is not possible.

So My question is that how would you guys implement this requirement ?

Our web application contains a Java Applet that handles the whole local client access issue. As you said, security settings will prevent you from getting the full path, and as far as I know only a signed applet will be able to circumvent the issue.

You can also let the applet handle opening the file from disk.

Here's an example[^] on how to handle JavaScript-Java communication.

But that would require users to install JRE. Right ?? I am looking for something in .Net.

Yes, the applet runs on the client's machine. I'd love to know a different way to break out of the browser's sandbox, because using a signed applet is far from ideal (for example when Oracle decides to change the security model *sigh*), but as far as I know there isn't any. So if you really need this functionality, a signed Java applet is the way to go.

Is there any .net equivalent ?

I believe Silverlight also runs in a sandbox. Breaking out of the sandbox requires a change in policy files on the client machine, and that might not even apply to silverlight apps running in a browser (not sure). Perhaps someone else has a better solution for this issue.
