I've found that sending binary data over the internet is risky. A zip file
or base64 encoded file avoids most transit corruption.

Hi Mike,
I have 60+ machines running windows7 embedded running a POS/TILL
system also a few tablets running windows and android with the same
system - wth abouth 8 lines of code added to work on Android.
In the first version of the system I save the arrays which held all
the Clerks orders/totals etc and items into an external stack every
time they added an item.
I then saved the whole thing and cleared the "dirty" flag on shutdown.
If the"till" program started and the dirty flag was true then system
would know it was a powercut and load all the "open" orders and other
status information etc.
I have users who have not had a problem in over 2 and a half years
others who have 3 "tills" with no problems and just a few maybe (4 who
have had a corrupt stack maybe 1 to 3 times a years - 2 or three times
is too many. There is no rhyme or reason because others have had
powercuts (6 in an hour ) with no damage but others can can switch off
without exiting the till properly without a problem and yet I can have
a corrupt stack with everything shut down properly. So Now I have
removed that stack and just save the arrays to "general" config
table called TABS in sqlite in a row with an idkey of '99' other
IDkeys can save other configuration information- NOT ONE PROBLEM since
I have done this - go figure.
I'll make a posting on the forum with the code - not trying to teach
my granny to suck eggs here, but maybe some beginners on the forum
might find it useful - would have done in the beginning.

I'm working on a session for next week's LCG. We are all working on
fun super-advanced pushing-the-envelope things in LC, but I wanted to do
something for the beginners who are watching LCG, and handling data seemed
like an obvious choice.
I have to admit, I haven't stored data in a stack in a long time, since the
database options are so easy to use. If you're currently storing data in a
stack, have you run into any issues on any platform with it, especially on
mobile, for instance, where the rules can be a little weird?
