Upload File from Client to Server (not using HTMLInputFile)

[Chris]

Hello,

I am using asp.net. I have been searching this for a while, but dint
find any solution yet. Any help will be appreciated.

I have a string variable say 'myFile' that has complete path of a file
located in client machine. eg:
Dim myFile as string = "C:/myFolder/File1.txt"

Clicking on a button should copy that file from local client to a
location in the server.

I am familiar with 'HtmlInputFile', but the property 'PostedFile' is
readonly. I can not assign my 'myFile' variables value to it. I am not
using HTMLInputFile b'coz I dont want to store the file when I select
it after browsing. I am storing it in a string variable and later on
(in the end), I have to save/upload it in the server.

Thanks,
Chris

hi chris
browsers implement very tight security when it comes to client file system
security.
as the developer you cannot decide which file the user will upload. and for
very good reason, imagine if you could retrieve my outlook PST file just
because i browsed to your site by mistake?
fortunately it is not possible to do what you asked. you may want to look
at a windows forms client which can be run with full access to the client
file system. if the user launches your app with full trust, then you can do
whatever you like with their files.

good luck
tim

You must be joking!

And a damn good thing too!!!

see previous reply. there is no way other than an active/x control. as
this control will be inherently unsafe, you probably can not find one to
buy, so you will have to build it.

also while this control could be written in .net, as its unsafe, the
user would have to mark it as trusted for it to be able to access the
file system.

That makes sense. I can not use windows application. It has to be web
app. I'll try something else.
Thanks for your help !! I appreciate it.
