Well,i figured DXE was limited in this,I had allready  read
the FAQ about it....Looked like a super pain to use in the
manner i would want......

AH ha...I found that:

http://nanosoft.hypermart.net/

and DLM:

http://www.fukt.hk-r.se/~flognat/hacks/DLM/


I think there is hope after all,though both of them
have rather little in the way of docs and how to's.I guess
i will have to play around with using them for a while
b4 i can integrate the idea into my projects...

Ok,I was just grasping at straws here.I am  glad that there
is DLX and DLM to play with.

Does anybody know of any other packages like these or
any more info or how to's related to them OR even tools
that help in using them...?

Thanks,
 Krogg.
