    Daten aus einer Website einlesen

    Hallo NG,

    zum erstellen einer Anfrag an eine Website benutze ich folgenden Code:


    Dim encoding = New System.Text.UTF 8Encoding

    'Daten zum Posten zusammenbauen

    Dim postData As String

    postData = "username=" + TextBox1.Text

    postData += ("&password= " + TextBox2.Text)

    'in ein Byte-Array umwandeln

    Dim data() As Byte

    data = encoding.GetByt es(postData)

    Dim myWebRequest As Net.HttpWebRequ est

    Dim myWebResponse As Net.HttpWebResp onse

    'Website zu der die Anfrage gestelt werden soll

    myWebRequest =
    myWebRequest.Cr eate("https://secure.ycn.com/quickaccess/ycnadsl/phptool.php")

    'POST

    myWebRequest.Me thod = "POST"

    myWebRequest.Co ntentType = "applicatio n/x-www-form-urlencoded"

    myWebRequest.Co ntentLength = data.Length

    Dim NewStream As System.IO.Strea m

    NewStream = myWebRequest.Ge tRequestStream( )

    NewStream.Write (data, 0, data.Length)

    NewStream.Close ()

    'Abschicken...

    myWebResponse = myWebRequest.Ge tResponse()

    NewStream = myWebResponse.G etResponseStrea m()





    Das scheint auch zu funktionieren, doch wie kann ich die Daten die mir die
    Website zurückliefert z.B. in ein String einlesen?





    mfg

      What are your questions in ENGLISH or are you just promoting something?

          Maximilian,

          Can you show us how and where you use this code and than with in English
          please.

          Although a major part of the messages (questions and answers) in this
          newsgroup is done by non native English speaking people, is the used
          language English, will you be so kind to do that as well.

          For questions asked in the German Language there are active newsgroups
          microsoft.publi c.de.german.ent wickler.dotnet. vb
          and when it is entwickler ASP
          microsoft.publi c.de.german.ent wickler.dotnet. asp

          I hope this helps?

          Cor

                  Are you able to translate the original question for us non German speaking
                  people please Herfried?

                  Now, if it was in Polish I wouldn't have a problem :)

                      The OP wants to download a file from the web and assign the file's content
                      to a string.

                          Crouchie,

                          bez problem

                          zum erstellen einer Anfrag an eine Website benutze ich folgenden Code:
                          To fulfil a request from a website do I need the next code

                          'Website zu der die Anfrage gestelt werden soll
                          Website where the request will be done

                          Das scheint auch zu funktionieren, doch wie kann ich die Daten die mir die
                          Website zurückliefert z.B. in ein String einlesen?

                          Thas seems as welll to funcion, however how can I get the data that the
                          Website returns read into a String.

                              Herfried,

                              You make me curious where did you assume that download, it has something to
                              do with to get a request using post.

                              However I see code I don't understand. When I had written this by instance
                              (with what it was) than I had directly gotten an question fom you from which
                              language it is. (It is not used in the code by the way)

                              Dim encoding = New System.Text.UTF 8Encoding
