Re: Unable to download large files using FTP (resource problem)

No, that's the first I can recall hearing of that specific problem. Don't
worry about the flash. If it's a modern device, you'll be tired of that
same old card and will throw it away and buy the latest version/capacity
before you run into a problem with too many writes. The flash cards all
handle moving things around so that the write limitations don't affect you
too much.

Thanks.

I found out I can use a flag indicating to use an intermediate file
instead
of writing to the cache, when needed. This seemed to solve my problem with
receiving large files over the FTP (which were previously saved to the
object
store) on the target.
My only concern is the number of "write" actions that are performed during
this operation, since we will be using a Flash memory card and the number
of
"write" (delete) operations over it is limited.

Do you happen to know what block size does the FTPGetFile function use
when
the INTERNET_FLAG_NEED_FILE is on, or if this should cause a problem?

You could check for a file called ceconfig.h in the \Windows folder.
That

sure
if that gets included in WM devices, but it does in generic Windows CE
devices.

Hi Paul,

Thank you very much for your quick and informative response.

The FTP freeware was actually designed for an ARM board.

Though we will try to test the application on the target board shortly,
I would like to know what component(s) we are missing on the emulator
we
built.

Is there a way to see the components that are included in the Windows
mobile
5.0 pocket PC?

You found freeware FTP client applications to try to run on the
emulator,
but you didn't say what *platform* they were targeted for. Pocket PC
would
be a likely answer and, if your OS isn't built with the same set of
components as Pocket PC, or if the installer for the freeware clients
is
checking *specifically* for that particular platform, that would cause
the
problem.

The basic fact is that emulators are piling so many network layers on
top
of
one another that they are not really appropriate test platforms for
real
network programs. You verified that, generally, your code works on
the
emulator and that's better than I would have expected. Don't waste
much
time trying to make it work perfectly, as it never will and your time
would
be better spent actually making the code run right on a real device.

Hi all,

We are developing an emultor of an ARM board using winCE5.0 (with
the
platform builder).
I have implemented an FTP client in visual studio 2005, using the
wininet
library over this platform.

The client seems to be working fine over other emulators (such as
Windows
mobile 5.0 pocket PC).
It also works fine over our platform when transfering short files.
(I
use
my
PC as the server).
But when I try to receive a larger file (over 1MB) with our
emulator,
the
FTP client gets stuck, and when pinging my PC from the emulator, I
receive
the following error message:
PING transmit failed. error code: 11010,
which I saw is related to QOS and is a result of lack of resources
(?).

I would like to know what is causing this problem (and how to fix
it,
of
course :) ).

Another little thing - I tried to execute some freeware FTP clients
for
wince on our emulator (by copying the .CAB file, or running a setup
over
my
PC and connecting through ActiveSync), but the emulator does not
recognize
these programs as winCE applications.
Is our emultor missing a component?

Thanks in advance, and have a great weekend,
~Y
