Do use HttpWebRequest but log in in the same session...

Thanks your quick answer. But how to show the content back to webbrowser?

Sergey Alexandrovich Kryukov 23-Feb-14 13:05pm

Oh, are you sure you need to show anything? You say that you need to get the id. Anyway, I don't know what scenario do you want to have, maybe you need to think on it yourself. WebBrowser is only needed when you want to create a browser application, basically...

yes, I need it bro. I want select some options for targeting people here https://www.facebook.com/search/users/all. After searching done with a list as I want, I need get all user id from that but it just 12 user. When browser scroll down, it will load more. I need get all of them.

Sergey Alexandrovich Kryukov 23-Feb-14 13:55pm

Well, I am still unclear about the big picture. If you downloaded some page using HttpWebRequest, well... roughly speaking, you can store it all in temporary file(s) and use it as URL for your browser... something like that.

And the idea to load anything additionally while the browser scrolls down... is weird, to say the very least. I feel you need to review your whole approach.

Use the facebook api instead of screen scraping.
