CInternetSession and varible questions

How can I send what the user enters into a Editbox to my server? I am trying to make my little FTP program, but would like to know the persons name and email address.
And how can my dialogs know what the user enters in a different dialog's listbox?
Lets say they select ftp.dira.net from a listbox on the first wizard step. On the next page it will connect to ftp.dira.net or what ever they selected. Such as ftp.download.com or ftp.installshield.com. Any ideas?
Oh, and also when I use CInternetSession and CFtpConnection it will not download big files for some reason. It screws up after about 30 sec. Can anybody tell me why???

Thanks All!
