File Transfers

[Guest]

I need to transfer a file from a central computer(Windows XP) to multiple 'branch' computers(WindowsNT/Windows2000) on a weekly basis. This transfer should be done programmatically in C#, when a user clicks a button or a menu item. After the transfer, we need to run a Script/batch file on each client computers. The problem is none of these computers are connected to the internet, but they have modems and can connect to telephone lines.

We could do this manually using Hyper Terminal, but we want to program this in C#. We prefer a solution that doesn't make use of internet. Solutions using Hyper Termial APIs too are welcome.The solution we are looking at is something similar to what Hyper Terminal performs - Far away computers connected via Telephone lines. We cant use cables

Thanks for your help

SI,

If there are API functions that expose the Hyper Terminal API, then you
can access those in .NET. Other than that, you will be severly limited in
what you can do, as most of the remoting functionality assumes some sort of
network.

Because of this, you will have to write two separate apps, one for the
branch computers, and one for the central one. The branch computers will be
in a wait state, and when the central computer calls, it needs to accept and
make a connection. You would have to format the messages yourself, and
process them when you receive them on the other side. Then, based on the
contents of your message, you perform an action.

Hope this helps.

It sounds like he might also need some Serial Port APIs, such as the one
here:

Hi,

What about RAS?

You could establish a RAS connection to the remote XP machine and then use
a TCP/IP connection to transfer the file , under this configuration you have
to program only the client as the server only needs to have the RAS service
turned on.

Cheers,
