Peeling the url how to?

i have a list of urls for home pages of classified sites. on each of url there is a form for posting the ads.
every time when i want to post an ad, i have to go through the home page, then locating the form ad link, and when the form appears i post my ad, some sites have 3 or 4 steps down the link of the form.

is there a way i can locate the ad form directly, or can anyone write some vb6 or c++ code for me to this chor automatically.

thanks in anticipation!

Filling in forms can be done via libcurl's POST methods. There are examples of it on libcurl's webpage I know.

any other help, coz i don't know much about libcurl library, can anyone do that for me.
