other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

I am trying to retrieve a 'tag'(Is it called that?) from an XML webpage. Once I make a post request from my vb.net app it sends a command to my online webserver and redirects me to a page that has entries that change each time. The page that im redirected to that changes each time looks something like this:
<mainpage> <id>hello</id> <random>176</random> </mainpage>
What vb.net code would I use to retrieve the id (In this case 'hello') and store it in a variable.
i'm working on a code that i want to start creating new classes with but i want to know if there's a more direct way to send the variables used in the form to a new class for storage.

Dim ClassName As String
Dim Grade As String
