Perhaps I'm not being clear: What *programming* problem are you trying
to solve?

I ask because it seems you are focussed to much on some specific
method, when it is very likely that your problem is better solved
using different methods.

I *did* give a solution. If that doesn't work for you, please tell us
more about the problem so we can provide better solutions.
