WEBBROWSER kontrola - otvaranje stranica po tajmeru

^{04.05.2011. u 17:23 - pre 158 meseci}

Pokusavam da napravim da mi Webcontrola na 10 sekundi menja strane.
onaj deo koda if i = 10 i if i = 20 necu tako vec cu po i da vucem iz baze string za navigaciju.
Ali ono sto ne mogu da napravim da mi uopste i za ove dve strane radi.
Poenta je da dok se to desava da se moze kretati kroz formu i koristiti tu stranu u webbrowser-u.
Kako na najbolji nacin to da izvedem?
Puno hvala!

Code:


    Dim thread1 As System.Threading.Thread

    Sub looping()
        If Me.InvokeRequired Then
            Me.Invoke(New MethodInvoker(AddressOf looping))
        Else

            Do While i <> 10000
                i = i + 1
                Label1.Text = i

                If i = 10 Then
                    WebBrowser1.Navigate("www.google.com")
                End If
                If i = 20 Then
                    WebBrowser1.Navigate("www.facebook.com")
                End If

                Me.Refresh()
                Threading.Thread.Sleep(1000)

            Loop
        End If
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        thread1 = New System.Threading.Thread(AddressOf looping)
        thread1.Start()
    End Sub

End Class

Ovo izgleda kao da ce da blokira celu aplikaciju, Me.Invoke tera glavni thread da pozove looping() koji sadrzi Sleep. Drugo ne znam zasto koristis thread sa Sleepom za cekanje, koristi Timer kontrolu i njen Timer event.

if it walks like a duck and quacks like a duck, it could be a dragon doing a duck
impersonation.

ako sam dobro razumjeo...

Treba da si u stanju da parsiras/napravis scrapping stranice? i da si siguran da se ista ucitala?

Onda koristi

//Kod je c#, ali ga prilagodi :)

Code:

webBrowser1.Navigate(new Uri("http://negdje...")); //idi na stranicu...

private void webBrowser1_LoadCompleted(object sender, NavigationEventArgs e) //osiguraj da se ista ucitala
        {

mshtml.HTMLDocument doc3 = ((mshtml.HTMLDocument)this.webBrowser1.Document);
string[] htmlkod= a.body.innerHTML.ToString().Split('>');
//radi sa html-om sta zelis...

        }

Mozes to sve uraditi i na tezi nacin:

Code:

protected void Page_Load(object sender, EventArgs e)
    {
        //string strBuffer = "email=" + username + "&pass=" + Password + "&login=Login";
        string strBuffer = "email=xxxxxxxxxxx&pass=xxxxxxxxxxxxx;login=Login";

       start_post(strBuffer);
    }

    public void start_post(string strBuffer)
    {
        //Our postvars
        byte[] buffer = System.Text.Encoding.ASCII.GetBytes(strBuffer);
        //Initialisation

        HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create("https://login.facebook.com/log...2F%2Fm.facebook.com%2Fhome.php");
        //Our method is post, otherwise the buffer (postvars) would be useless
        WebReq.Method = "POST";
        //We use form contentType, for the postvars.

        WebReq.ContentType = "application/x-www-form-urlencoded";
        //The length of the buffer (postvars) is used as contentlength.
        WebReq.ContentLength = buffer.Length;
        //We open a stream for writing the postvars
        WebReq.Referer = "http://www.facebook.com/index.php?";

        Stream PostData = WebReq.GetRequestStream();
        //Now we write, and afterwards, we close. Closing is always important!
        PostData.Write(buffer, 0, buffer.Length);
        PostData.Close();
        //Get the response handle, we have no true response yet!
       // HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
       // //Let's show some information about the response
       //WebResp.StatusCode;
       //WebResp.Server;

        //Now, we read the response (the string), and output it.
        using (HttpWebResponse response = (HttpWebResponse)WebReq.GetResponse())
        {
            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
            Response.Write(reader.ReadToEnd());

            }
        }
    }
