Hi Randy,

Thanks for the pointers. I checked the resources you mentioned and they have
been a big help.

To be a little more specific about the project requirements:
    - it would be nice to be able to indicate the progress of the downloads,
although not required.
    - the downloads need to support basic Proxy authentication (this is a
must)

>From what I have looked at so far, it looks like going with the WinInet API
is my best choice. I have spent a bit of time with Mr. Morcillo's code, and
it looks like a good starting point for what I am trying to accomplish.
However, I ran into some very serious memory problems when downloading large
files (>5MB). I contacted Mr. Morcillo by email in the hopes that he can
help me with it.

Thanks again for your comments. If you can think of anything else, please
let me know!

Regards,

GSM
