Caros colegas, esse exmplo mostra o envio de um arquivo via socket, do server para o cliente



unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    ClientSocket1: TClientSocket;
    ServerSocket1: TServerSocket;
    btnTestSockets: TButton;
    procedure ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
    procedure ClientSocket1Disconnect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure ClientSocket1Connect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure ServerSocket1ClientConnect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure btnTestSocketsClick(Sender: TObject);
  private
    FStream: TFileStream;
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.ClientSocket1Read(Sender: TObject;
  Socket: TCustomWinSocket);
var
  iLen: Integer;
  Bfr: Pointer;
begin
  iLen := Socket.ReceiveLength;
  GetMem(Bfr, iLen);
  try
    Socket.ReceiveBuf(Bfr^, iLen);
    FStream.Write(Bfr^, iLen);
  finally
    FreeMem(Bfr);
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  FStream := nil;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  if Assigned(FStream) then
  begin
    FStream.Free;
    FStream := nil;
  end;
end;

procedure TForm1.ClientSocket1Disconnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
  if Assigned(FStream) then
  begin
    FStream.Free;
    FStream := nil;
  end;
end;

procedure TForm1.ClientSocket1Connect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
  FStream := TFileStream.Create(�c:\temp\test.stream.html�, fmCreate or fmShareDenyWrite);
end;

procedure TForm1.ServerSocket1ClientConnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
  Socket.SendStream(TFileStream.Create(�c:\temp\test.html�, fmOpenRead or fmShareDenyWrite));
end;

procedure TForm1.btnTestSocketsClick(Sender: TObject);
begin
  ServerSocket1.Active := True;
  ClientSocket1.Active := True;
end;

end.

Espero ter ajudado.
