Strange Application Behaviour

[Guest]

I recently purchased a new PDA (Compact Ipaq 3870) and have noticed some
strange application behaviour since I have begun using the PDA.

Essentially the program that I have developed unexpectedly exits, freezes
up, and sometimes throws a stackoverflowexception. It should be noted that
this occurs after several forms are loaded into the memory (I am using the
formstack example to create a multiform application). I should also note that
I am using CF 1.0 SP3 and the latest version of the smart device framework
from opennetcf.org.

I never had these problems when I was using my Toshiba E740 (with the Intel
XScale PXA250 400 MHz processor). Thus, is this a result of the PDA and the
SA1110 processor that it is using, or is it a code issue?

I know this question is somewhat broad, but I am perprlexed that my app is
acting this way.

Thanks Again,

Tim

Most probably it's a code issue. Try to see which line throws the
stackoverflowexception.

Alex,

Thanks for the reply. I suspected that as well.

I have found a lot of problems unique to the iPAQ. I market a custom
program for handhelds. The only, and I mean ONLY, brand I have had any
problems supporting the program on is iPAQ. I have had zero support calls
on any model other than iPAQ. iPAQ handles a number of things in memory
differently then other brands. Also, the iPAQS seem to come with various
small parts of the operating system not installed, allowing them to
apparently make the claim of more available memory. Most of the support
calls I get result in a need for the user to install some feature of the
operating system that all other brands include, but iPAQ did not.

James thanks for the reply.

Could you provide some more insight as to what elements that the IPAQ Pocket
PC os may be missing and how to go about installing them?
Thanks,

Generally from my experience, it tends to be dll files. The simple
answer, and since I do not own an iPAQ the only answer I have to offer,
is reload the system from the source disk and isntall everything. That
naswer tends to clear all problems for my customers every time.
