<h2>

everything i tried failed so far.

What I have tried:

VB

webrewq.Timeout = 60000
webrewq.Method = "GET"
Dim hwresponse As Net.HttpWebResponse = webrewq.GetResponse()
If hwresponse.StatusCode = Net.HttpStatusCode.OK Then
    Dim responseStream As IO.StreamReader = New IO.StreamReader(hwresponse.GetResponseStream())
    Label1.Text = responseStream.ReadLine()
    responseStream.Close()
End If

So what happens?

[no name] 3-Oct-20 10:32am

Right now this code just gives me the whole page source but i only need the inner text of that tag

Of course it does, because that is what the GET operation returns. If you want to extract a specific part then you have to add code to search through the returned text.

Instead of doing that, have a look at the HTMLAgility pack[^] - it's available via NuGet in VS - if you are doing anything with web scraping it makes your life a whole load easier:

C#

HtmlWeb web = new HtmlWeb();
HtmlAgilityPack.HtmlDocument doc = web.Load(url);
string title = doc.DocumentNode.SelectSingleNode("//title").InnerText;
HtmlNodeCollection h2Nodes = doc.DocumentNode.SelectNodes("//h2]");
HtmlNodeCollection divNodes = doc.DocumentNode.SelectNodes("//div[@class='pre-action-link']);

Or if you must use VB:

VB

Dim web As HtmlWeb = New HtmlWeb()
Dim doc As HtmlAgilityPack.HtmlDocument = web.Load(url)
Dim title As String = doc.DocumentNode.SelectSingleNode("//title").InnerText
Dim h2Nodes As HtmlNodeCollection = doc.DocumentNode.SelectNodes("//h2]")
Dim divNodes As HtmlNodeCollection = doc.DocumentNode.SelectNodes("//div[@class='pre-action-link']);")

Have a look at the documentation - it can really make your life eaiser!
