Try InternetGetConnectedState().
Btw:You'd include wininet.h and wininet.lib

You'd open the Project menu and choose the Setting sub-menu.Then choose LINK at top  and add the wininet.lib to the object/library module edit box...

FYI:
DWORD dwCheck = INTERNET_CONNECTION_MODEM;

BOOL check = InternetGetConnectedState(&dwCheck, 0) ;
