c# website manipulating user file on desktop

Posted on 2012-03-29
Last Modified: 2012-04-09
Hi Guys,

I have created a website which will grab a specific excel file on the users desktop and manipulate contents.  The catch is I have only done this on my local machine in microsoft visual web developer 2010 express, and have not put on web host yet.  So I have not tested it on the actual internet as of yet.

It obviously works local.. but my question is there has to be some type of security to allow a website to read a users pc and manipulate a file.  What strategy to I go about confronting this issue?  Will it just fail in a live environment, or will it ask user to allow manipulation?  Or do I need to write some type of code to ask user to allow?

Thank in advance

Unfortunately this will fail in a live environment, it is working now as you machine is acting as the Server when running so it is allowed to manipulate files on the 'server'.
However in a live environment it will be breaking security to try and access a local users file system through the browser.

instead up having the user upload the file.  Someone recommended something about creating an activeX object, downloading it to the user, and manipulating that object.... this is above my head at the moment but I might have to learn... can you explain this process?

Sorry that is beyond my knowledge, don't use ActiveX objects as they can only be used by Internet Explorer generally.

thanks jacko, appreciate you input... I may have to do the upload but hopefully I can figure out this activex idea.  

Does anyone have any input on activex?

Or even if its not activeX, are there any more suggestions for my website to manipulate a specific excel file on the users desktop.  I'm doing some google searches and finding things like Web Deploy, but not sure if I'm on the right track.
