Ich nehm mal an, dass du eine Verbindung mit dem Internet erstellen möchtest...Wenn nicht dann sags!

Versuchs mal

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;
