I am using an InstallScript CA and call InternetGetConnectedState function (Wininet.dll).

Hi Holger~
It sounds like a good idea.
Could you please explain more or attach some codes.
Thanks a lot

Something like this:

prototype Wininet.InternetGetConnectedState(POINTER, NUMBER);

nResult = UseDLL (WINSYSDIR  ^ "Wininet.dll"); 
bInternet = (InternetGetConnectedState(&dwState, 0) != 0);
UnUseDLL ("Wininet.dll");

But note, that InternetGetConnectedState returns the state only so you may want to evaluate that a little more deeper.

Hi there~
It does work fine~ Thanks.

One more quick question for ya, if u can reply in ease.
Do you have tipis or code example about using InternetGetConnectedStateEx?

I try to use InternetGetConnectedStateEx(0, url, dwNameLen, dwReserved), but I cannot retrive any value from the function call.

Many many thanks to Germany!!
