I don't know about the VB binding, but the C binding doc says
CURLOPT_POSTFIELDS "should be the full data to post". You can't concatenate
data strings with multiple calls this way.

This is on the right track, but you're missing some literal "&" characters.
There's one there before UserID and UserPW, but missing before the others.

Synthesizing your own cookies seems problematic. If the remote site ever
changes this, your code will break. Better would be to do a GET or other
operation to receive the cookie ahead of time.
