Delphi-Quellcode:

function getfile(server, username, password, remotefile, localfile: string; port: word = 21): boolean;
var
  hopen, hconnect: HINTERNET;
begin
  hopen := InternetOpen('myagent', INTERNET_OPEN_TYPE_DIRECT, nil, nil, 0);
  hconnect := InternetConnect(hopen, pchar(server), port, pchar(username), pchar(password), INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0);
  Result := FtpGetFile(hconnect, pchar(localfile), pchar(remotefile), False, FILE_ATTRIBUTE_NORMAL, FTP_TRANSFER_TYPE_UNKNOWN, 0);
  InternetCloseHandle(hconnect);
end;

procecdure TForm1.Button1Click(Sender: TObject);
begin
getfile('SERVER', 'USERNAME', 'PASSWORD', '/updates/update.ini', extractfilepath(paramstr(0))+'update.ini');
end;

Es wird keine Datei erstellt.

Was ist falsch?
