Hi Farshid,
Thanks for the code and information about GLIntercept. I wasn't aware about
the GLIntercept security hole, but it doesn't surprise me that it can happen.
No security is going to be fool proof, but we can at least try to make it a
little more difficult. Plus, it makes the managers happy. ;-)
Anyway, I'll give the std::stringstream a try. I'm not very proficient when it
comes to the std library, but I'm learning. It certainly looks
straight-forward enough.
Thanks,
Brian
