Last Modified: 2010-05-18

I need to know how to use the dial up connections from Dellphi (using V5).  Can anyone help.  Also, what are the pros and cons rather than using something like Async.

use InternetAutoDial
 - this will connect you to the internet with the default connection
 - check the flags for dialing type
 - use InternetAutodialHangup to hangup

use InternetDial
 - this will connect to the net with the specified connection
 - use InternetHangUp to hang up, as parameter use the value returned by the InternetDial function

all in the wininet.pas unit

I'm not using it for internet, I want to dial a PC at the other end to transfer files.  Will this still work, and do you have any examples?

you can do that
I have :)
just set up a dialup connection to dial into that PC
the ip of the machine is the one assigned by it's DHCP server or it's static IP
to download a file you use ftp protocol or your own

I had a look at soe of the samples, thanks.  

What I want to do is connect two computers together and transfer a file from one to another.  I currently use Async Pro, but find that I have to do a lot of work to get the file across (because I use passwords etc).  I thought I could use Dial-Up to take the effort aways from the app, and let the connection handle the modem stuff.  What I would like is a method of connecting/receiving the file automatically.  The dial up connects to te net ok, how do I get a Delphi app to listen???  How do I initiate the send/receive automatically.

help please.  I will increase the points for a good solution.
