Hi All,

I have tried to use the function InternetGetConnectedState like this:

BOOL check = InternetGetConnectedState((unsigned long *)INTERNET_CONNECTION_MODEM, 0) ;

But when I ran my program, an unhandled exception error occured.

I have already included the wininet.h and link the wininet.lib at my projoect.

What is the problem? How can I use this function to check the network connection by modem/LAN.......

How about this instead:


BOOL check = InternetGetConnectedState(&dwCheck, 0) ;

Think about what you are saying with:


You are using a cast to FORCE a constant into a pointer.  Not the desired result!
