Question

I’m in the process of building a web application in ASP.NET MVC C# (including ajax/jquery) and have to save a file locally to the client’s hard drive.

I have another application that polls a directory for new files, so it’s essential the files from the website ends up at that location so therefore showing a “save as..” won’t work.

What alternatives do I have? (Sadly I can’t rewrite that external application to work in any other way.)
Should I write the web application in silverlight instead?
Should I use an ActiveX object? ActiveX feels so 1995 though.. Are there any other variants nowadays?

Answer 1

I’ll vote for Silverlight solution.

But instead of developing your site entirely with Silverlight, just write a small and hidden Silverlight component that would receive a remote file location and stores it in user’s local file system.

Check this other answer in Stackoverflow:

• Does Silverlight 3 have access to local file system, Open Excel, and print reports?
