Server zum Empfangen von Eingaben in Textboxen aus Internetseiten

GermansolvedQuestionVisual StudioDevelopment
Hallo,
ich habe einen Server (http://93.212.205.2:7000),
auf dem ich jetzt eine Textbox integrieren möchte, und zwar so:

<form action="process.phtml" method="post">  
							<b>Name:</b> <input type="text" name="amount" size="10" maxlength="10"> <b>NP</b>&nbsp;&nbsp;<input type="submit" value="Einzahlen">  
						</form>

Wie mach ich jetzt mit einem TCPListener, dass er die daten abfängt?

Hi

das ist ein normales HTML Formular, also brauchst du keinen TCP Listener. Das macht der Webserver bzw. ein Skript das auf dem Webserver läuft für dich. Hier die Grundlagen zu HTML Formularen http://de.selfhtml.org/html/formulare/index.htm

Da rein möchte ich jetzt die FORM mit der Textbox integrieren, und beim absenden an den Port 7001 senden. Auf 7000 sitzt der WWW-Server im Browser.
Wie mache ich das?

Hi

<form action="http://93.212.205.2:7001/" method="post">

Auf der IP an dem Port muss dann ein Programm laufen das den HTTP Post Request annimmt, versteht und auswerten kann (also ein Webserver)

Sorry, das quote ist durchs kopieren rein. Dir URL von dir stimmt.
Willst du jetzt wirklich einen Webserver in VB programmieren ? Googel einfach mal, vielleicht hat das schon wer gemacht. Ich glaube nicht dass dir hier wer nen Sourcecode liefern kann/will

Habs jetzt so probiert:
<code vb>Option Strict Off
Imports System.Net
Imports System.Net.Sockets
Imports System.IO

Public Class Form1
Dim stream As NetworkStream
Dim streamw As StreamWriter
Dim streamr As StreamReader
Dim client As New TcpClient

Dim server As TcpListener
Dim ipendpoint As IPEndPoint = New IPEndPoint(IPAddress.Any, 8000)
Dim t2 As New Threading.Thread(AddressOf Main)

Sub Main()
server = New TcpListener(ipendpoint)
server.Start()
client = server.AcceptTcpClient
stream = client.GetStream
streamr = New StreamReader(stream)
streamw = New StreamWriter(stream)
While True
rtf1.AppendText(streamr.ReadLine & vbCrLf)
End While
End Sub

Private Sub Button1_Click() Handles Button1.Click
t2.Start()
End Sub
End Class

Funktioniert aber auch nicht...

Hi,
habe mich jetzt ein klein wenig mit PHP befasst und habe die Lösung in weniger als 10 Zeilen Code geschafft
