.NET Forum / ASP.NET / General / May 2008Trying to upload files programmaticly
I'm trying to upload/download files programmaticly to a records management system. I have it working fine on my dev machine using vb.net code-behind pages but when I place it on the server when it goes to upload files it (datatable of file paths and data stored in a session var) it errors because the code can't find the files. It seems to be trying to read the file from the server drive not from the client machine. My code is meant to read the file into a memory stream then feed it to a web service call that stores it into the DB. Any ideas? If there is a utlility that I can buy to programmaticly upload/ download files I'd do that well. I need to do both actions without user interaction and coordinate that with my web services to manage the files and data. Thanks in advance.

Yes, that's exactly what's happening. On your development machine, server and client are actually the same physical machine... > If there is a utlility that I can buy to programmaticly upload/ > download files I'd do that well.

You have (almost) no chance whatsoever of doing this, for fairly obvious security reasons... Imagine a public website which could upload and download files to and from client browsers without user interaction - you'd be surfing away quite happily while the site was freely downloading malware and uploading your accounts file, password list etc... All modern browsers are designed specifically to prevent this sort of functionality - don't even bother trying...  SignatureMark Rae ASP.NET MVP http://www.markrae.net I agree it does sound like a security nightmare - but would it not be possible to 'share' a drive on each PC with the server. Then the server could then just reference the shared file area, eg. \\mypc\mysharedfiles\myfile.doc Just a thought, Mark > I agree it does sound like a security nightmare - but would it not be > possible to 'share' a drive on each PC with the server.

It is the browser, not ASP.NET per se, which blocks unassisted downloads and uploads Take the browser out of the equation, and anything is possible. What your suggesting is hardly any different from network utilities which deploy patches and service packs to workstations.
