How can I download a file form Server to client?
8  6344 
Using what protocol?
You could quite easily use WebClient.Downl oadFile() to download a file over
HTTP .. is there some specific way you are looking to download this file?

Thanks,
I want to download file from the virtual directory of my web application.
The file name is mine.zip.
But the first parameter of the WebClient.Downl oadFile is URI.
How can I give the first parameter of the WebClient.Downl oadFile() ?

There is also a string version .. http://msdn2.microsoft.com/en-us/lib...nloadfile.aspx
The URI method also has a constructor which takes a string I believe.

It will not ask user when I use WebClient.Downl oadFile do download a file
from server.
But I wnat that the user can confirm before download.
How can I do ?

How can I download a file form Server to client?
Erm, perhaps by using a MessageBox.Show before calling DownloadFile?
Or have we miunderstood your usage? (and to be fair, Greg did ask, but you
didn't answer). Is the client an app or a browser? (it makes a big
difference).
Marc
Sorry,
The client is browser.

OK then; various options:
If the file itself is publicly available on the web-site, then you could
just hyperlink to it (assuming that MIME is a download type, not an inline
type)
Another similar option is to use HttpResponse.Tr ansmitFile; this will push
the file back to the client on the current response.
To prompt for a download box, you want to set the "content-disposition" HTTP
header to "attachment ; filename=someth ing.blah" - this should make the
browser display a "Save As..." dialog to save the current response to disk.
You may be able to use this with TransmitFile, and if it fails you could
just pump the stream yourself.
Another way is to change the "content-type" header to
"applicatio n/octet-stream"; this catch-all MIME type is generally prompted
to save, but it gives less information about what the file really is. One
advantage, however, is that it /might/ (not definite; haven't tried it) be
possible to set this as a customer header on a folder on your web-server -
so that everything in (for instance) /Download/ gets this MIME type and thus
is prompted for save.
Some starters for 10 ;-p

customer = custom; damned spell checker

I'm writing a client-server app.
Client controls Server which in turn configures and controls
a bunch of hardware.
I want to be able to start the server from my client.
Now in C/C++ one could simply run the appropriate
command string through a standard "system()" call
which is relatively simple.
JAVA on the other hand seems to require something like
RMI to do it.

I have, or is this the best method? Could I use a com object that ran

Hello,
Is it possible to read a CSV from the Client, and bind my Datagrid to the

I have tried and in Debug mode on my workstation it works fine, but when I

Has anyone done this before? If so, how do I do it? I'm new to ASP.net so
