I am trying to figure out how to make a form where the user types a url in a text box then they hit a button and the source code of that page will show up in another text box. It is being used for a text editor such as text pad. I know how to make it where they can hit a button and get the source code from the site I specify such as

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim myRequest As WebRequest
        myRequest = WebRequest.Create("http://www.yahoo.com")
        Dim theResponse As WebResponse = myRequest.GetResponse()
        Dim responseStream As Stream = theResponse.GetResponseStream()
        Dim reader As New StreamReader(responseStream)
        Dim sb As New StringBuilder
        Do
            sb.Append(reader.ReadLine)
            sb.Append(vbCrLf)

        Loop While Not reader.ReadLine Is Nothing
        TextBox1.Text = sb.ToString()
    End Sub
End Class

However I want it where they can pick any site through a text box by typing the url and hitting submit any ideas?

So... a textbox's "text" property returns the string from the textbox, right? Why not use that in line 3 and not the hard coded address?

I was actually trying to do something like that but I could not seem to write it correct. Thank you for the fast reply.

Well.. how are you trying to write it? I mean it's a pretty basic swap.

[ak4744710]

well I tryed several differant ways but I am pretty new to vb and just could not figure it out I was trying things like this

        myRequest = WebRequest.Create.textbox2.text
        

[modi123_1]

WebRequest.Create("http://www.yahoo.com")

If the method create takes in a string why would you be trying to use the dot-operator to find a method or property called 'textbox2'? Why not just keep the method call (we know it is a method call because it has the ( and ) ), and just use the textbox's method?

WebRequest.Create(textbox2.text)

Thank you so much I tryed several ways and it was driving me crazy I even tryed like this

WebRequest.Create("textbox2.text")

once earlyer but I should have realized it was the "" that was messing me up lol. Thanks so much for the help.

[modi123_1]

Do you know *WHY* the quotes were messing you up? Anything in a pair of quotes is automatically treated as a string and _NOT_ an object with a property call.

[ak4744710]

No to be honest I did not know that but glad I do now. It seems like it can be confusing but the more attention I pay Im noticing it gets pretty basic once you get practice and learn it.

Hi,
You can also use (DownloadString) to get the source of the page. This is a little code that lar3ry showed me that may be a little smaller and less complicated.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Using wb As New System.Net.WebClient
            Dim s As String = wb.DownloadString(TextBox2.Text)
            Dim txt() As String = s.Split(CChar(vbLf))
            For Each line In txt
                TextBox1.Text &= line & vbNewLine
            Next
        End Using
    End Sub
