接受部分(有个用户和密码check,你取消就可以)

主要发送部分
procedure dClick(Sender: TObject);
var
 FStream : TFileStream;
begin
 if ted then begin

   if FileName = ‘‘ then
  MessageBox(Handle,‘没有选择文件‘,‘Error‘,MB_OK)
   else begin
  try
  FStream := (FileName,FmOpenRead);
  on := 0;
  (0,0);
  tream(FStream,true,false);
  Finally
  ;
  nect;
  end;
  (‘Transferred OK‘);
   end;
 end
 else
  begin
   MessageBox(Handle,‘没有连接服务器‘,‘Error‘,MB_Ok);
  end;
