>>I'm working on an app where the user is going to want to send a fax from within the application. Anyone done this? I checked the files section, but I didn't see much.....thanks.

>MS Fax is easiest, like KJ said, but doesn't allow for completely automating the process. (pulling the name and number from your app for instance) For this, you will probably want to go with a 3rd party product like WinFax Pro. Winfax (and many other fax programs) make their functions available to other programs through OLE, DDE, or ActiveX controls.

You can cheat a little with MAPI - send the fax as an e-mail with address formatted as [FAX:NUMBER] and it will all be automated (e.g. [FAX:+44 131 220 3320] - the square brackets must be included).
