Question : MFC CString - valid IP Address ?

I have a MFC GUI which takes an IP Address..

Its a CString and I would like to ensure that the data is a valid multicast IP Address.

Has anyone this check done previously to save time.

Thanks

Answer : MFC CString - valid IP Address ?

Use inet_addr(), it's simpler:


CString ipAddress = "127.0.0.1";

if (inet_addr((const char *)ipAddress) == INADDR_NONE) {
   // address is no good
}
