What do you mean exec?

execute thats what i mean by exec

this is what i have so far...

Code:

---

int main(int argc, char* argv[])
{
  int ich;

  while ((ich = (argc, argv, "abc"))) {
    switch (ich) {
      case 'a': /* Flags/Code when -a is specified */
        printf("test a");
        break;
      case 'b': /* Flags/Code when -b is specified */
                /* The argument passed in with b is specified */
                /* by optarg */
        printf("test b");
        break;
      case 'c': /* Flags/Code when -c is specified */
        printf("test c");
        break;
      default: /* Code when there are no parameters  */
        printf("test none");
        break;
    }
  }
    return 1;
}

What do you mean by executing URLs? :confused:

Code:

---

while ((ich = (argc, argv, "abc")))

No way, what should this line do?

i dont know, im trying to figure out how to make an aplication that i can execute something like this "c:\folder\app -h host.dns.com -u username -p password" and it will update my dns.

But what do you mean by executing an URL? :confused:

i need to be able to send a http request though tcp in my program, like you do in telnet with "GET HTTP/1.0" i need to be able to send that through the command line program im making.

Try Winsock Sockets. Do some research on MSDN

im using borland...so do you have any sujestions for that?

Can't you simply write an input file for telnet?

Code:

---

telnet < input.txt

i could but im trying to write a program to do the same thing. i want to learn how things are done.
