Webscrape into Visual Studio VB Form - vb.net

Question

I've got a form that looks like the following:
I would like to simply enter the stock, click the get price button, have the button return the price it scraped.
I'm experienced with Excel VBA and how to scrape but not so much how it translates into Visual Studio (VB language)
Below is what I've got for the form so far. I attempted to add the HTML document and Internet controls methods already. So far I can get it to successfully open and shut internet explorer--I just can't get it to scrape anything. It just errors out, and I can't dim internet explorer as an HTML object. Below is the code so far...
Public Class Form1
Dim stockBox As Single
Dim price As Single
Private Sub Label1_Click(sender As Object, e As EventArgs) Handles Label1.Click
End Sub
Private Sub Label2_Click(sender As Object, e As EventArgs) Handles Label2.Click
End Sub
Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
End Sub
Private Sub Label3_Click(sender As Object, e As EventArgs) Handles Label3.Click
End Sub
'Private Function READYSTATE_COMPLETE() As Object
'Throw New NotImplementedException()
' End Function
' Private Sub DoEvents()
'Throw New NotImplementedException()
' End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim ie As Object
Dim px As Single
ie = CreateObject("InternetExplorer.Application")
With ie
.Visible = True
.navigate("http://finance.yahoo.com/q?s=" & (TextBox1.Text))
'Do
' DoEvents
'Loop Until ie.readyState = READYSTATE_COMPLETE
'Dim doc As HtmlDocument
'doc = ie.document
While ie.readyState <> 4
End While
On Error Resume Next
px = ie.GetElementById("yfs_l84_" & (TextBox1.Text)).InnerText
ie.Quit
End With
Label3.Text = px
End Sub
End Class
