You have the right idea.  Two problems I see are: (1) you should use
TYPE_COUNT rather than TYPE_INT (count is unsigned, int is signed), though
that shouldn't matter in practice; (2) I don't understand the line:

	updaterec->Assign(1, myPath);

What is updaterec and why are you assigning element 1 rather than element 0?
