Hi !
I promise that is the last question :)
Synchronous function "Put" always return false, but file is
succesfully transfered to server...
I don't know why... Please, help :)
Server Source
FFtpServ := TFtpServer.Create(nil);
FFtpServ.OnStorSessionClosed := OnAfterPut;
FFtpServ.OnValidatePut := ValidPut;
FFtpServ.Addr := FAddr;
FFtpServ.Port := FPortFTP;
FFtpServ.TimeoutSecsIdle := 0;
FFtpServ.Start;
procedure TDM.OnAfterPut(Sender: TObject; Client: TFtpCtrlSocket;
Data: TWSocket; AError: Word);
var
Script: string;
begin
if AError = 0 then
begin
Script := '_' + Client.FileName;
F7z.SZFileName := Client.FileName;
F7z.Extract();
FScript.ExecuteFile(Script);
DeleteFile(PChar(Script));
end;
end;
procedure TDM.ValidPut(Sender: TObject; Client: TFtpCtrlSocket;
var FilePath: TFtpString; var Allowed: Boolean);
begin
FilePath := FDir + '\' + ExtractFileName(FilePath);
end;
Client Part
FFtp := TFtpClient.Create(nil);
FFtp.MultiThreaded := True;
FFtp.UserName := 'lab';
FFtp.PassWord := 'lab';
FFtp.Binary := True;
FFtp.Port := DM.FPortFTP;
FFtp.HostName := DM.FHostServ;
FFtp.LocalAddr := DM.FHost;
FFtp.LocalFileName := 'filee'
FFtp.HostFileName := 'filee'
if not FFtp.Connected then
FFtp.Connect;
if FFtp.Connected then
begin
FFtp.TypeSet;
if FFtp.Put then
begin
end;
end;
