Answer 1

I use this function to post data. But the url you pass has to be formatted as such for example

http://example.com/login.php?userid=myid&password=somepassword

Private Function GetHtmlFromUrl(ByVal url As String) As String

        If url.ToString() = vbNullString Then
            Throw New ArgumentNullException("url", "Parameter is null or empty")
        End If
        Dim html As String = vbNullString
        Dim request As HttpWebRequest = WebRequest.Create(url)
        request.ContentType = "Content-Type: application/x-www-form-urlencoded"
        request.Method = "POST"


        Try
            Dim response As HttpWebResponse = request.GetResponse()
            Dim reader As StreamReader = New StreamReader(response.GetResponseStream())
            html = Trim$(reader.ReadToEnd)
            GetHtmlFromUrl = html
        Catch ex As WebException
            GetHtmlFromUrl = ex.Message
        End Try

    End Function
