Hallo Lezers,
Ik heb een code gevonden die ik graag zou willen gebruiken, hellaas krijg ik de volgende fouten niet weg. ik heb al winsock toegevoegd in references waardoor axmswinsocklib en mswinsocklib erbij kwam maar dat heeft niet geholpen..
de fouten:
The type or namespace name 'Socket' could not be found (are you missing a using directive or an assembly reference?)
he type or namespace name 'Thread' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'ManualResetEvent' could not be found (are you missing a using directive or an assembly reference?)
en dit is dan de code die ik heb gekopieerd in visual studio 2005
public partial class Form1 : Form
{
Thread t1;
int flag = 0;
string receivedPath = "yok";
public delegate void MyDelegate();
public Form1()
{
t1 = new Thread(new ThreadStart(StartListening));
t1.Start();
InitializeComponent();
}
public class StateObject
{
// Client socket.
public Socket workSocket = null;
public const int BufferSize = 1024;
// Receive buffer.
public byte[] buffer = new byte[BufferSize];
}
public static ManualResetEvent allDone = new ManualResetEvent(false);
public void StartListening()
{
byte[] bytes = new Byte[1024];
IPEndPoint ipEnd = new IPEndPoint(IPAddress.Any, 9050);
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
try
{
listener.Bind(ipEnd);
listener.Listen(100);
while (true)
{
allDone.Reset();
listener.BeginAccept(new AsyncCallback(AcceptCallback), listener);
allDone.WaitOne();
}
}
catch (Exception ex)
{
}
}
public void AcceptCallback(IAsyncResult ar)
{
allDone.Set();
Socket listener = (Socket)ar.AsyncState;
Socket handler = listener.EndAccept(ar);
StateObject state = new StateObject();
state.workSocket = handler;
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
flag = 0;
}
public void ReadCallback(IAsyncResult ar)
{
int fileNameLen = 1;
String content = String.Empty;
StateObject state = (StateObject)ar.AsyncState;
Socket handler = state.workSocket;
int bytesRead = handler.EndReceive(ar);
if (bytesRead > 0)
{
if (flag == 0)
{
fileNameLen = BitConverter.ToInt32(state.buffer, 0);
string fileName = Encoding.UTF8.GetString(state.buffer, 4, fileNameLen);
receivedPath = @"C:\Users\Name\Desktop\" + fileName;
flag++;
}
if (flag >= 1)
{
BinaryWriter writer = new BinaryWriter(File.Open(receivedPath, FileMode.Append));
if (flag == 1)
{
writer.Write(state.buffer, 4 + fileNameLen, bytesRead - (4 + fileNameLen));
flag++;
}
else
writer.Write(state.buffer, 0, bytesRead);
writer.Close();
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
}
}
else
{
Invoke(new MyDelegate(LabelWriter));
}
}
public void LabelWriter()
{
label1.Text = "Data has been received";
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
t1.Abort();
}
}
}
Alvast bedankt voor jullie reactie:thumb:
