My boss asked if I could write something that would navigate a client's PC for a text file, upload it to the IIS server, do my magic, and then replace the file on the client side. (He does this
frequently in PHP, but I'm using ASP.NET.)
This is not possible in PHP or ASP.NET.
If I had to, I could write a Windows Form executable in C#, but I'd like to avoid that if possible. Browser-based would be best, if this can be done.
Writing a Windows application and installing the app on the client PC is the only way.
