End Google Ads 201810 - BS.net 01 --> Hi,

actually my question is simple, but still I couldn't find the answer. I searched everywhere.
In my project I have a webBrowser control. Before the webBrowser control navigates from one page to another, I have to intercept the post data, so I can analyze it. If for example I would be on a page with a form, and I click on the button to submit the form, I would have to get somehow the data the webpage wants to send via POST.
I work on solving this problem for a long time, so any help would be greatly appretiated.
And sory for my bad english, I'm not a native speaker.
