I've been using the code of SampleCollapse (don't even remember where I got it from, PalmOne, PalmSource, ...) in my own project and it's driving me insane. _Insane_, I tell you.
SampleCollapse is in the PalmSource developer KB -- go to kb.palmsource.com, search for it, and make sure you have the most recent code.
I shine any light on your other questions right now -- I've not done much with the DIA in my own applications yet, but other people here have and they should be able to help.
