HI ,

i have a Resultion for you. Use the Online Help for VS DOT NET.

Keywords : TCPClient. You got Information about different Classes. e.g Networkstream. You must import the Classes System.Net.Sockets and System.Text

*************************************************

Dim tcpClient As New TcpClient()

 

' Uses the GetStream public method to return the NetworkStream.

Try

tcpClient.Connect("HOSTNAME", 21) ' Verbindung herstellen

 

Dim networkStream As NetworkStream = tcpClient.GetStream()

If networkStream.CanWrite Then

Dim sendBytes As [byte]() = Encoding.UTF8.GetBytes("USRENAME")

networkStream.Write(sendBytes, 0, sendBytes.Length)

networkStream.Flush()

 

Dim sendBytes1 As [byte]() = Encoding.UTF8.GetBytes("PASSWORD")

networkStream.Write(sendBytes1, 0, sendBytes.Length)

networkStream.Flush()

 

Else

'Console.WriteLine("You cannot write data to this stream.")

MessageBox.Show("You cannot write data to this stream.")

tcpClient.Close()

Return

End If

If networkStream.CanRead Then

 

' Reads the NetworkStream into a byte buffer.

Dim bytes(tcpClient.ReceiveBufferSize) As Byte

' Read can return anything from 0 to numBytesToRead.

' This method blocks until at least one byte is read.

networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))

 

' Returns the data received from the host to the console.

Dim returndata As String = Encoding.ASCII.GetString(bytes)

'Console.WriteLine(("This is what the host returned to you: " + returndata))

MessageBox.Show("This is what the host returned to you: " + returndata)

 

Else

'Console.WriteLine("You cannot read data from this stream.")

MessageBox.Show("You cannot read data from this stream.")

tcpClient.Close()

Return

End If

Catch e As Exception

'Console.WriteLine(e.ToString())

MessageBox.Show(e.ToString())

*************************************************

But my Code has a mistake. I can make a connect to the ftp server, but i can not login in. I searching for a resultion this time.
