Symbol PPT 2800

Thank you.

Hmmm.

Yes, I do.  At one point I was able to run the emulator, but not use the
scanner.  I noticed the sample applications account for whether a scanner is
attached to the device or not.  I am trying to do the same thing so I can
look at what I'm doing on my desktop.



Very impressive.  Thank you for the tips.

Julian,

That explains it then. Although, as others have pointed out, Microsoft thinks
smart minimize is a good thing and for many apps it probably is, I'm happy to
see that on the Compact Framework we'll have the option to use smart minimize or
the old PocketPC OK which closes the app.

I forgot to mention, I'm using Embedded Visual C++ 3.0

Symbol do use custom platforms, and custom platform GUIDs.  But it wouldn't
be the first time if they'd managed to get the platform GUID in the SDK
different from that set on the device.

Fix this by using Remote Registry Editor to look at the HKLM\Windows CE
Tools key on the device, and changing Platform to match the subkey you find
in HKEY_LOCAL_MACHINE\SOFTWARE\Mi­crosoft\Windows CE Tools\Platform
Manager\{F384D888-F9AA-11D1-BB­9E-00A0C9C9CCEE} with a '(Default)' value of
"PPT2800_2002" on your desktop.

Long-standing bug in eMbedded Visual C++.  If a different CPU architecture
is mentioned, you DO have the wrong device connected (e.g. 'The SHx SH3 CPU
does not support configuration ARM...').

Unsurprising.  You're trying to write a scanning application and link to the
scanning DLL's import library - why would the emulator have the scanning DLL
or its import library?  There's no scanner.  If you need to keep the app
portable, either write a 'stub' DLL for the emulator or link dynamically to
the scanning library with LoadLibrary()/GetProcAddress()­.

You realise that you're using the Pocket PC 2000 emulator there, right?

Just to show that it's possible, I'll point you at my company's demo (which
I wrote, with a great deal of advice from my colleagues):
http://www.5d.co.uk/downloads. htm and look for 'Proof of Delivery Demo
(Pocket PC)'.  The ARM version should run on both a 2800 and a Compaq iPAQ -
the same executable.  This was done by dynamically importing the Symbol
scanning library.

Symbol PPT 2800_2002.  Its a PocketPC2002.

Julain,

I had the same experience with 1) but agree that's no problem, and it's
mentioned on the Symbol site with a workaround.

I haven't tried remote debugging since I sold my wireless unit so I haven't run
into the 2nd one, and I didn't hit the 3rd one yet either.

Oh for gods' sake - don't any of you lot READ the documentation?

It's supposed to do that.  Microsoft's aim with Pocket PC is to produce a
PDA.  For fast responses, they want to keep all apps in memory until there's
not enough memory to do something, which is the whole reason for the
WM_HIBERNATE behaviour.  Smart Minimize was introduced to give the user the
impression that they are closing the application, but in fact it stays
running, so that next time they 'run' the application it comes back a) very
quickly and b) where they were last time.  The aim was to try to provide a
better experience than Palm, where only one program actively runs at a
time - nothing happens in the background, and each program must store and
reload its state, even if the user just wants to change the system time or
some such.

You can argue whether this is a good thing or not, but nevertheless - if you
want to write for Pocket PC and Pocket PC 2002, you should abide by the
guidelines.  If you don't, expect your users to get very confused.

If you really don't want your app to minimise when the user presses the
Smart Minimize button, don't show it; you can remove it by adding the
WS_NONAVDONEBUTTON style to your top-level windows.  But don't close -
that's not what is being requested.

You could also argue the point of Symbol producing what is essentially a
vertical market device based on a PDA platform, but personally (despite what
I may have said before) I prefer the 2800/8100 to the PDT 7200, which is a
custom CE 3.0 device, and has a completely non-standard shell.

Are you running PocketPC or PocketPC2002? We've got Symbol 2800s running
PocketPC in the field and nobody reported this problem to me yet, but it sounds
like the behavior of the "smart minimize" button on 2002.

Ginny

Assuming that you have the 2002 version of the PPT2800, Set ShowOK = True
for the form(s) and App.end in the OKClick event. I'm curious - have you had
issues with the PPT2800 SDK?

Rob Agnew

Oh definitely...

1) When building the Arm configuration, I get a message, "The targeted
platform PPT2800_2002 does not match the connected platform.
Continue?"  I always click yes and the app runs fine.

2)When I try to debug remotely, I get the message, "The CPU does not
support configuration ARM!  Executable will not run on device.
Continue?"  Needless to say, the message holds true, I can't debug the
application.

3)I've reached a point with the application where I can't build the
Win32 (WCE x86em) Debug or Release active configuration.  I get a
"LINK : fatal error LNK1104: cannot open file 'ScnAPI32.lib'" error.

Other than that, I think its ready for general release, what do you
think?  Just kidding.  I'm sure I'll have these issues cleared up by
the time I'm ready to do some real testing with the device.  But, any
suggestions would be helpful at this stage.

The behavior your describing is actually "as designed" for
some reason MSFT does not unload the application when you
click the (x) box in the top right corner. The way to
shutdown a app is from the pop-up keyboard Ctl-q. This
works on all the pre installed MSFT apps. This key
sequence has to be hard coded into apps to it may not work
for all thrid party add-on apps.
