Read a file from the client side

[Laura]

Hi:

¿How can I read a file on the client side without loading it to the server?

Hi Laura,

As Mark mentioned, it's unsafe to read files directly from the client side.
A malicious web site can easily steal your private information if it's
allowed.

Mark raised two drawbacks when using ActiveX:
1. ActiveX can only work for IE users.
2. The user has to run the risk of allowing web sites to read all his local
files.

It's true. I think a better solution is to use a cross-browser plug-in. For
example, we can use Silverlight (it's still in Beta but will be released
soon). In Silverlight we can read/write files in the Isolated Storage,
which is a data storage mechanism that provides isolation and safety. The
default quota of the storage is 1MB. The program can only read/write files
in the Isolated Storage. Thus the two drawbacks are eliminated.

To get started, please install following tools first:
Microsoft Silverlight Tools Beta 2 for Visual Studio 2008:

B7D7-C0DBA8866434&displaylang=en

How to use Isolated Storage:

Please feel free to let me know if you need further assistance. You can
also ask questions in the Silverlight forum:
