Re: [fpc-pascal] lNet getting the local IP

I think you want to use 127.0.0.1 to return the actual address. In my case I would const CN_GDNS_ADDR = '127.0.0.1'; run the progarm and the output would be 192.168.1.5 as long as there is an active interface. On Thu, Oct 7, 2010 at 3:34 PM, silvioprog wrote: > Hi Brian, >

:o A hard coded address will of course fail if it cannot be reached. The code was an example, you should use it as such. I substituted my router's ip for google's and it works.;) Choose a different address that would not fail in a specific situation. As another example, one could rea
