Post method with frames

Hi all, (VB6 SP3 IE5 W2000Pro)
Here is little description, what do I need to do...
I want to send a POST request for frameset page, containing 2 frames (first
is the query, second is response for this query, when first is submitted)
I did some ways to do it...
1. Using Inet VB component... Cannot retrieve frames source code (I need it
to analyse the query details) (response - This page uses frames, but your
browser doesn't support them)
2. Using wininet.dll ..... the same request
3. Using WebBrowser object... probably easiest way to do it, but I am not
sure, if it is possible to use POST method on it.

Can someone help me please? I would be pleasured to receive a code example,
eighter to pass POST request on frame, eighter to pass retrieving frames
HTML code.

Thanx a lot in advance.

Regards Roman
