Sorry, Max
I don't see any problem with MemHandleSize: it really expects a handle.
DmWrite wants a pointer and it gets is!
But here migh be another one:
PackReminder( &r, h2 ); // PackReminder will resize the handle
How you pass h2 ? Do you pas it by reference or by value ?
In the latter case you might not get it right after internal resize.

Subject: Re: Saving Form Results to a DB (DmWrite Bus Error)
This is rather basic programming error. Look at the DmWrite function
prototype. Does it require a MemHandle where h2 is?
If you use emulator you should be given hint on that. Anyway, this type of
error (crashing on single function) is way too easy to debug. I'd recommand
you bookmark the API reference site at Palmos.com to get easy reference on
those.
