Submit data & Grab an element by ID using httpwebrequest? - ipman_98 - Feb 21, 2016
hello everyone! I need help with vb programming.
What I want to do is enter data to a text area in a webpage & grab it's output from another text area using IDs. I know how to do this with WebBrowser Control in VB, but I really want to try this with httpwebrequest. Please help me.

With webrequests you just get the page source. Find out what requests are sent, using Fiddler or Charles, and mimic them in VB.net and then read the response and parse the information you want (Html parsing, string splitting, regex, json deserializing, whatever).

Use webrequest to get Post data and Regex for grabbing the ID

Use webrequest to get post data...? What?
And regex is probably the worst for grabbing the ID.

Depends on the response, but string splitting would be fine.
Also, you dont get post data. You post post data.

string splitting sucks ass for parsing data from a html document

If it is one value you need then its perfectly fine.
