Versuch mal das:
Delphi-Quellcode:
uses
WinInet;
// Causes the modem to automatically dial the default Internet connection.
procedure TForm1.Button1Click(Sender: TObject);
var
dwConnectionTypes: DWORD;
begin
dwConnectionTypes := INTERNET_CONNECTION_MODEM + INTERNET_CONNECTION_LAN +
INTERNET_CONNECTION_PROXY;
if not InternetGetConnectedState(@dwConnectionTypes, 0) then
// not connected
if not InternetAutodial(INTERNET_AUTODIAL_FORCE_ONLINE or
INTERNET_AUTODIAL_FORCE_UNATTENDED, 0) then
begin
// error
end;
end;
// hangup the default Internet connection.
procedure TForm1.Button2Click(Sender: TObject);
var
dwConnectionTypes: DWORD;
begin
dwConnectionTypes := INTERNET_CONNECTION_MODEM + INTERNET_CONNECTION_LAN +
INTERNET_CONNECTION_PROXY;
if InternetGetConnectedState(@dwConnectionTypes, 0) then
// connected
InternetAutodialHangup(0);
end;
Damit sollte die Internetverbindung automatisch verbunden(Button1Click) bzw. getrennt(Button2Click) werden...
