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
