Question

I want to wait until internet comes so i created a loop with InternetGetConnectedState function.I started program when internet is disabled.Then I enable internet.But still it can ‘t exists.What should i do?

    LPWORD bur;
int abc;
    abc = InternetGetConnectedState(bur,0);
    while (abc==0){
    printf ("zzz");
    if (abc==1)
    break;
    }

Answer 1

try putting the call in the loop , abc will never change.

Also, you shouldn’t assign the result to abc….also, its a DWORD…

DWORD abc = 0;
printf ("Waiting for an internet connection.");
 while ((abc & 0x40)){
    InternetGetConnectedState(&abc,0);
    printf (".");
}

and then comparing it to 1 or 0 is not really going to tell you anything, have a look at the flags it can return :-

INTERNET_CONNECTION_CONFIGURED
