Internet connection exist/de

Zurück zur Seite Code Beispiele.

Dieser Artikel beschäftigt sich mit der Windowsprogrammierung.

Das Unterprogramm stellt fest, ob eine Internetverbindung besteht.

Das Beispiel stellt fest, ob eine Internetverbindung besteht:

pascal
uses
  WinInet, Windows, ...;
  
  ...
  
// Die Funktion prüft, ob der lokale PC eine Internetverbindung hat
function funIstOnline: boolean;
var
  dwrFlag: DWord;
begin
  Result := False;

  dwrFlag := Internet_Connection_Modem or Internet_Connection_Lan or
    Internet_Connection_Proxy;

  if InternetGetConnectedState(@dwrFlag, 0) = True then
    Result := (dwrFlag = 81);

end;
