Delete(CmdStr,1,6);
Password := DecryptString(CmdStr,20504); //CmdStr;
if CompareStr(Password,'123abc')=0 then
begin
Memo1.Lines.Add('Login..........Accepted');
Memo1.Lines.Add('Connected......'+DateTimeToStr(Now));
CmdStr := '';
AThread.Connection.WriteLn('<Accepted>');
end
else
begin
Memo1.Lines.Add('Password Wrong...Login Failure');
AThread.Connection.WriteLn('<Failed>');
CmdStr :='';
AThread.Connection.Disconnect;
end;
end; //4
end;
主要发送部分
procedure TTCP_Client.BtnSendClick(Sender: TObject);
var
FStream : TFileStream;
begin
if IdTcpClient.Connected then begin
IdTcpClient.WriteLn('<SEND>'+ExtractFileName(FileName));
if FileName = '' then
MessageBox(Handle,'没有选择文件','Error',MB_OK)
else begin
try
FStream := TFileStream.Create(FileName,FmOpenRead);
FStream.Position := 0;
FStream.Seek(0,0);
IdTcpClient.WriteStream(FStream,true,false);
Finally
FStream.Free;
IdTcpClient.Disconnect;
end;
Memo1.Lines.Add('Transferred OK');
end;
end
else
begin
MessageBox(Handle,'没有连接服务器','Error',MB_Ok);
end;
end;
