請問: ClientSocket1.Socket.SendStream ClientSocket1.Socket.SendBuf 這兩個有什麼差別............ SERVE都可以用Socket.ReceiveBuf這個來收ㄇ ClientSocket1.Socket.SendStreamThenDrop 還有這個是幹ㄇ的.....看不懂ㄝ    還有剛剛看了PORT的問題請問 TCPIP的PORT不同有差別ㄇ 看到有人說傳檔案用一個PORT           傳命令用另一個PORT           這樣SERVE如何判斷是哪個PORT的阿....    拜託各位大大幫忙......謝謝......

關於SendStream和SendBuf的不同 我想help on line 說的相當的明白

Use SendBuf to write to the socket connection. Call this method from
the OnSocketEvent event handler of a Windows socket object or in the 
OnWrite or OnClientWrite event handler of a socket component. 
Alternately, Use SendBuf to write when a connection is first formed 
when the socket does not expect notification that the socket on the 
other end of the connection is expecting to read.    For non-blocking sockets, the data is sent to the WinSock DLL which 
has it's own internal buffers. If the WinSock can accept additional 
data, SendBuf returns immediately with the number of bytes queued. 
If the WinSock internal buffer space is not able to accept the 
buffer being sent, SendBuf returns -1 and no data is queued at all. 
In this case, wait a bit for the WinSock to have a chance to send 
out already-queued data; then try again.    For blocking sockets, SendBuf returns the number of bytes actually 
written.     If an error occurs while writing to the connection, SendBuf 
terminates the connection and throws an ESocketError exception.    Use SendStream to write to the socket connection. The writing may 
occur in the OnSocketEvent event handler of a Windows socket object 
or in the OnWrite or OnClientWrite event handler of a socket 
component. Alternately, SendStream may write from a socket that is 
expected to write to the connection without a notification to signal 
the connections readiness to read. SendStream reads information 
from the stream indicated by AStream and writes it to the socket 
connection. The value returned by SendStream indicates whether any 
information was successfully written to the connection.    Note:        The Stream passed as a parameter to SendStream becomes o
wned?by the windows socket object.  The Windows socket object frees 
the stream when it is finished with it.  Do not attempt to free the 
stream after it has been passed as a parameter.

SendStreamThenDrop的說明

Use SendStreamThenDrop to write to a socket connection when the 
connection is no longer needed after the writing is complete. 
SendStream reads information from the stream indicated by AStream 
and writes it to the socket connection, shutting down the connection 
when it is done. The value returned by SendStream indicates whether 
any information was successfully written to the connection.    Note:        The Stream passed as a parameter to SendStream becomes o
wned?by the windows socket object.  The Windows socket object frees 
the stream when it is finished with it.  Do not attempt to free the 
stream after it has been passed as a parameter.

你問到ReceiveBuf都可收嗎，答案，可以.. port的問題請看網路概論的書 就像ftp來說，也是需要同時開兩個port 發表人 - turboted 於 2003/06/21 12:12:54
