hi,

uses wininet;
 
 
function IsConnectedToInternet : bool;
begin
dwConnectionTypes := INTERNET_CONNECTION_MODEM +
                          INTERNET_CONNECTION_LAN
                          + INTERNET_CONNECTION_PROXY;
 
    if InternetGetConnectedState(@dwConnectionTypes, 0) then
      Result := True
    else
      Result := False;
end;
