Detect a Broadband connection

Hi,

I need a function that will do this:

if (user has a broadband connection) then showmessage('Broadband')

else if (user has a normal dial up connection) then showmessage('Dialup');

Hi siwiher,

here is an example code to detect internet connection. you could find out connection type by changing dwConnectionTypes variable value. this detects all kinds of connection.

uses
   WinInet;

function IsConnectedToInternet: Boolean;
var
  dwConnectionTypes: DWORD;
begin
  dwConnectionTypes :=
    INTERNET_CONNECTION_MODEM +
    INTERNET_CONNECTION_LAN +
    INTERNET_CONNECTION_PROXY;
  Result := InternetGetConnectedState(@dwConnectionTypes, 0);
end;

Regards.

I'm a little inexperienced could you give me a working example which would
detect a broadband connection and dialup.

There's an extra 50 points in it for you if it works!

Sorry lads maybe i have not made myself clear - i can detect an internet connection

however I need my program to tell me what type it is - broadband or dialup

basically if the internet is always on I need to know about it

if the user uses a dialup then I need to make the distinction between the two!

i have channged the procedure. maybe this helps.

// no connection returns 0
// dial-up returns 1
// broadband returns 2
function GetConnectionType: integer;
var
  dwConnectionTypes: DWORD;
begin
  dwConnectionTypes := INTERNET_CONNECTION_MODEM;
  if InternetGetConnectedState(@dwConnectionTypes, 0) then
     result := 1
  else
  begin
     dwConnectionTypes := INTERNET_CONNECTION_LAN + INTERNET_CONNECTION_PROXY;
     if InternetGetConnectedState(@dwConnectionTypes, 0) then
        result := 2
     else
        result := 0;
