哪位大侠有点对点文件传输的源码？200分求购，急！！！(200分)

哪位大侠有点对点文件传输的源码,可象QQ那样的传文件，收文件，我试了好多的
网上的源码，都不行，哪位有已调好的，我试过后若没问题，一定给分

唐晓峰大虾的代码，我调试无误，请参看：
服务器：
unit Unit1;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
ScktComp, StdCtrls;

type
TCon = record
FileName : String;
TotalSize : Integer;
Status : Integer;
end;

PCON = ^TCON;

TForm1 = class(TForm)
Button1: TButton;
SS: TServerSocket;
// SS: TServerSocket;
// Button1: TButton;
procedure Button1Click(Sender: TObject);
procedure SSClientConnect(Sender: TObject; Socket: TCustomWinSocket);
procedure SSClientRead(Sender: TObject; Socket: TCustomWinSocket);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation


{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
begin
SS.Port := 9000;
SS.Active := True;
end;

procedure TForm1.SSClientConnect(Sender: TObject;
Socket: TCustomWinSocket);
var c : pcon;
begin

c :=new(pcon);
c.FileName := '';
c.TotalSize := 0 ;
c.Status := 0;
Socket.Data := c;
Socket.SendText('已经连接,请输入UPLOAD FILENAME SIZE'#13#10);

end;

procedure TForm1.SSClientRead(Sender: TObject; Socket: TCustomWinSocket);
var C : PCON;
cmd:String;
Buffer : pointer;
nRetr : integer;
fs : TFileStream;
const bufferSize = 1024 ;

begin
C:= Socket.Data ;
case c.Status of
0 :
begin
cmd := trim(Socket.ReceiveText) ;

if Pos('UPLOAD ',uppercase(cmd)) > 0 then
begin
c.FileName := trim(Copy(cmd,Pos(' ',cmd)+1,Length(cmd)));
c.TotalSize := StrToInt(Copy(c.FileName,Pos(' ',c.FileName)+1,Length(c.FileName)));
c.FileName := trim(Copy(c.FileName,1,Pos(' ',c.FileName)));
c.Status := 1;
Socket.Data := C;
Socket.SendText('you can send File !'#13#10);
end;
end;
1 : begin
GetMem(Buffer,BufferSize);
nRetr := Socket.ReceiveBuf(Buffer^,BufferSize);

if not FIleExists('c:/'+c.FileName) then
begin
fs :=TFileStream.Create('c:/'+c.FileName,fmCreate or fmShareDenyNone);
fs.Seek(0,soFromBeginning);
end
else
begin
fs :=TFileStream.Create('c:/'+c.FileName,fmOpenWrite or fmShareDenyNone);
fs.Seek(0,soFromEnd);
end;

fs.WriteBuffer(Buffer^,nRetr);

fs.Destroy;
FreeMem(Buffer);
end;
end;
end;

end.

工作站代码：

procedure TForm1.SendCommandClick(Sender: TObject);

begin
//CS.Socket.SendText(Edit1.Text+#13#10);

end;

end.
绝对没有问题，如果仍然不行，给我你的邮箱，我发给你

这段代码我也试过，它怎样收文件呀，把文件存到哪里去了

而且也连不上远端的电脑

我有代码呀

procedure TForm1.ClientSocket2Read(Sender: TObject;
Socket: TCustomWinSocket);
var len:integer;
temp:string;
begin
if stStatue=stgetFile then
begin
Len:=Socket.ReceiveLength;
Temp:=Socket.ReceiveText;
filem.Write(PChar(Temp)^,len); //filem是一个文件流
inc(allLen,len);
if allLen=getfilesize then //allLen是文件长度，你先传送过来
ShowMessage('文件接受完毕！');
end;

发送部分
const
MAX_LEN=2048;

var
iSen:integer; //iSen发送出去的长度
iSize:integer; //文件长度 最好是全局变量
buf:array[1..MAXLEN]of char;
senlen:integer; //每次应该发送的长度
ret:integer; //实际发送的文件长度
filen:TFileStream; //最好是全局变量

iSen:=0;
while iSen<iSize do
begin
FillChar(buf,MAX_LEN,0);
if iSize-iSen>MAX_LEN then senlen:=MAX_LEN
else senLen:=iSize-iSen;
filen.Position:=iSen;
filen.Read(buf,senLen);
ret:=ClientSocket1.Socket.SendBuf(buf,senLen);
inc(iSen,ret);
end;

看这句代码：
fs :=TFileStream.Create('c:/'+c.FileName,fmCreate or fmShareDenyNone);
保存在c:/。


连不上远端电脑，看这句：
procedure TForm1.Button2Click(Sender: TObject);
begin
CS.Host:='127.0.0.1';
CS.Port:=9000;
CS.Active := True;
end;
主机为127.0.0.1，端口9000，当然只能联本机了
你在这里更改参数

to 张无忌
可否给我一份源代码，我测一下，没问题立即给分，我的Email: liuning72@163.com

既然你找无忌教主要，我就不发了，多少给点辛苦分吧[]

我上面的代码我测试过，没有问题，你稍做修改就可以用了

张无忌，你这段代码我试了一下，大的文件就不行了，好象不停的写

老兄，网络带宽怎么比得上硬盘传输率啊？
没有传完当然一直写喽

老大，我是在本地啊，传输的时候和硬盘传输率有关系吗？

我有，但是在局网上通过的，在公网上没实现（在大富翁上已提问），在传输前自动压缩，传输后自动解压。
