#3 is a bit confusing, but actually less than it used to be. WM2003 (Windows
Mobile) is the underlying Operating System. It is packaged on, and for,
various devices with specific flavors, such as the Pocket PC version, the
Smartphone version, the PocketPC Phone edition, etc. Each has their suite of
UI specifics and some hardware features and dependencies.
For the DB questions, I would go with Beverly's suggestion to take that to
the developer side. I don't think you will find HanDBase a good fit, if
Access compatibility is your primary focus. Last I checked, HandBase has a
proprietary format for the handheld and the desktop. The desktop version has
Access compatibility. So if you are looking to get data in an Access DB onto
the handheld, what you do is sync the Access DB to the desktop HandBase DB
and then the two HandBase products sync. Someone correct me if they have
changed this approach.
The direct Access capability on the PPC is extremely limited. There is an
ActiveSync conduit that converts .mdb stuff to .cdb (PPC) stuff. It limits
the conversion to tables only. No queries, forms, not even relationships,
transfer. All that must be done on the PPC with some third party product
that can read a .cdb. Todd Ogasawara has a nice piece on what will do that
at http://www.oreillynet.com/pub/wlg/3358.
I'm not sure Beverly's suggestion to use a card reader will buy you much.
You will wind up with a .mdb on the card, and there is nothing in the PPC
world that will read that, much less allow any manipulation.
If you really want to get into DB development on a PPC I think you might
want to look into SQL Server CE, and there are links on Todd's blog to that.
The only real emulator available for PPCs is in The Visual Studio style
development environment, which you may actually be looking at for app
development. Again the developer forums are your best bet.
