Internet communication

[Martin]

Dear all,

I woud like to create macro in excel using VBA which will log to
extranet pages via https and send and XML message. All communication
has to be encrypted by key that is stored in windows registry. XML
message is pretty easy but I don't know how to write a code which will
set up the communication (what library I should import, syntax etc.)

Would be nice to see some code examples or Q&A. Can anyone of you
please advise?
Thanks, Martin
