Read text from a website

Hello,
I'd like someone to give me the code for reading text of a website if thats possible.
For example
I want to read this from a website
<p class="welcome-msg">Welcome, username</p>
So the program will find the welcome-msg class
and will write down
Welcome, Username

bumb

Try this.

vb.net Code:

Dim html As String = "<p class=""welcome-msg"">Welcome, username</p>"
 
Debug.Print(Regex.Match(html, "(?<=<p class=""welcome-msg"">).+(?=</p>)").Value)

What is Regex?

I'll give you the same reply I gave somebody else 10 minutes ago.

Hover your mouse cursor over the red underscore, click on the red exclamation mark that appears and click on the 'Import' line.

And how can i make it so it will appear the welcome message on a textbox?

vb.net Code:

TextBox1.Text = Regex.Match(html, "(?<=<p class=""welcome-msg"">).+(?=</p>)").Value

For somereason textbox1.text writes Welcome, username. Where username i want to write the username it appears on the website

I simply showed you how to extract the text between "<p class="welcome-msg">" and "</p>".

If you want to extract it from a webpage, then you must first download the webpage. You can do that with WebClient DownloadString.

I am sorry but i never understand msdn.Microsoft.com, i will try though. But if it is possible for you, give me the full code. so i can read it and understand what it is from the source. Thanks

I bet you haven't even looked at that link. It's only three lines of code to download a webpage.

vb.net Code:

Imports System.Text.RegularExpressions
Imports System.Net
 
Dim html As String
 
Using wc As New WebClient
    html = wc.DownloadString("http://website.com")
End Using
 
TextBox1.Text = Regex.Match(html, "(?<=<p class=""welcome-msg"">).+(?=</p>)").Value

Well you are wrong. I looked at the link. I was realy close! I am proud since it was the first time i almost understand microsofts tutorials. I just didn't added the Imports System.Text.regularExpression . Anyways, thanks. I will try the code

EDIT: Wrong, they automaticly got in, so i don't know why my code didn't worked last time.

Here is another problem, Although the code works perfect, after login, it says Welcome guest, and not welcome name. And i can't findout why it does that. any idea?

Code:

---

Imports System.Text.RegularExpressions
Imports System.Net

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim Html As String
        Dim wc As New WebClient
        Html = wc.DownloadString("http://localhost/index1.html")

        LinkLabel1.Text = Regex.Match(Html, "(?<=<a class=""Url"">).+(?=</a>)").Value
    End Sub
End Class

This is Correct solution :check: but
how to read URL ?? :(

For some reason my website doesn't get updated really quick.
So as result, i don't get a Welcome, username and i get a welcome, Guest.
But if i see the webbrowser, i can see that it says on the browser welcome, username
and it doesn't say welcome, Guest
Any fixes?
Thanks!
