Please explain more exact what the problem is.
Can you send other data ?
Please read some actual threads in this newsgroup concerning
SendBuf().

I think it's the ultimate time that Remy publishes the code
(faq) he presented here many times, and so just redirect all
similar questions.
I haven't counted but it's maybe 20th time that the same
question reappears ;)

remy's code works perfectly...can you please tell me what changes should be
made in order to
see the download speed and how many bytes remain for download?this 2 things
i would like to be visible to the client and to the server too.. thank you
very much in advance for your help

as vladimir said remy posted a code for file send over tcp socket
(Look at the thread from 11. januar 2005 19:41
'please help me..socket file transfer')the code works excellent.i place a
client socket on one computer and a
server socket on another computer and i send file from server to client
using that code.
what changes should be made to this code in order to see also to the client
and to the server side
the download speed and the bytes remaining....i can post remys code again if
neccessary.

all code as it is. You know at forehand the size of the data. A while loop
is used to send chuncks of data. So at every moment you know how
much is sent. If you use GetTickCount() you know bytes/ms. So you
only have to ad some code in that loop.

well i understand what u mean,and it seems simple i will work on it.now one
final question and really sorry for the trouble of continuous
questions..basically its a rather stupid question but im new in
programming.:if i use indy trivial ftp components for file transfer means i
am using trivial ftp protocol,if i use indy ftp components for file transfer
means i am using ftp protocol etc. when i send
file through sockets in this way what protocol am i using?(or im not using
any protocol at all?) i mean that trivial ftp,ftp,icmp,http, etc protocols
have some security...through sockets which protocol am i using ?(in order to
understand what security is provided)

same server because the server speaks ftp.
and a server exchange messages. If the server send you a bunch of data
then it can for instance send four bytes (an int) first with the size
of the message. A client has to read that size first. As simple as it
is: this is a protocol. You have to know that the size comes first and
act accordingly.

Well basically i use the Caps Lock istead of the shift key..:)).By the way
ftp and trivial ftp are diffrent things
FTP:FTP is commonly run on two ports, 20 and 21. Port 20 is a data stream
which transfers the data between the client and the server. Port 21 is the
control stream and is the port where commands are passed to the ftp
server.FTP is an 8-bit client-server protocol,
TRIVIAL FTP:Trivial File Transfer Protocol (TFTP) is a very simple file
transfer protocol akin to a basic version of FTP
a.. Uses UDP (port 69) as its transport protocol (unlike FTP which uses
TCP port 21).
b.. It cannot list directory contents
c.. No authentication or encryption mechanisms
d.. Used to read files from/write files to a remote server
e.. Supports three different transfer modes, "netascii", "octet" and
"mail", with the first two corresponding to the "ascii" and "image" (binary)
modes of the FTP protocol.
from en.wikipedia.org/
so ftp and trivial ftp arent exactly the same protocols, are they?

and also tftp:Standard 33/RFC 1350
(www.rfc-editor.org/rfc/std/std33.txt) "The TFTP protocol (revision
2)" insteed of ftp:The protocol is standardized in RFC 0959 by the IETF
