At the risk of offending you, what Palm text book or reference are you
basing
this code on? It's wrong in too many ways to start explaining to you.
The pointer returned by MemHandleLock is thrown away and the path
variable, which I can't see ever being set to anything, is then used to
retrieve
the values. I can understand why other contributors to this group have
shown signs of impatience with your questions.
I suggest that you start by making small changes to a working sample
rather than stepping boldly into the deep end of the pool by trying to
create a complex app from scratch.
