My boss thinks we need to distribute our app on a ROM chip (if that's
correct) so the client does not loose the app when the device looses power.

What do I need to do this?

TIA,
Mike
 
For what device? There's probably no way to distribute it on a ROM chip,
given that no device is going to have an empty space for a new chip to be
installed (or a way to get to the main board, even if it did). You could
distribute the application on a Compact Flash, PCMCIA, or SD card, if the
target device can read one of those, I guess. If your application requires
registry entries, you're still going to have problems if all battery power
is lost.

This is for a Samsung/Verizon device - an i700. Maybe ROM was the wrong
term - I obviously don't know what I'm doing :) The documentation says
there's a "memory card" you plug in on the side of the device - it didn't
ship with one.

I'm going to call the manufacturer, but I think it's a compact flash card.
If that's the case, how do I write to one? Do I need some sort of burner?

Thanks,
Mike

Guess I need to see what the device allows you to plug in
 
That's probably an SD Card. Designed by Sony. It's a little stick kind of
like a stick of gum, but with FLASH memory (non-volatile), in it.

Unless you make the device, you probably can't.

Really? I thought this kind of thing was standard - but I don't know. Guess
I'm looking for the answer to "my application is lost when the device looses
power"

I've been sticking a copy of the install in the backup directory of the
device, but I don't think that's good enough for the client.
 
You can put your app on a persistent media device (which it sounds like your
device supports), but when the device loses power all RAM is wiped out, and
so any install information and reg settings will be gone. The user will
probably have to re-install from the persistent media whenever power is
fully lost.

It's possible that you can use autorun (though I think I've heard of
failures on the PPC03), which would allow you to set up an auto install when
the card is inserted.
 
Is it possible to have everything, also the cf files, in a sd card (given
the device can handle memory cards),
so I don't need to "execute" cab files to install it, and just put the card
into a "clean" device and run the app?
I mean, does ppc/cenet need to know where the cf .dlls are (and how) or they
can be copied in the app dir?

If the autorun feature works, simply make an EXE that copies the files for
you, so you control all of the logic.

Thanks Chris, but my question was slightly different.
Let's say that I don't want the installation of the cf files,
and i want to keep everything on a memory card...
is this possible or it's not worth doing?
Are there any registry keys i have to set up to let ce/ppc know where to get
cf dlls and use them from there?


If i make an exe i can copy files, ok, but where?

Thanks,
Matteo
