I am working on an application. That application should get the resume from the users, so that I need a code to verify whether a file exists or not.
I\'m using ASP.N
Simple answer is that you can't - you won't be able to check a for a file on their machine from an ASP website, as to do so would be a dangerous risk for them.
You have to give them a file upload control - and there's not much you can do with that control. For security reasons javascript can't really touch it.
They then pick a file to upload, and you have to deal with any empty file that they might send up server side.
