VS2005 + WinCE5 - Not a Valid Windows CE application error?

bob

Hi all

Up until last w

I was using the beta of VS2005 beta 2 to do some
test porting work on Window Mobile 5 platform without any problems.

Then suddenly I'm getting the "Not a valid Window CE Application
error" when I run any newly compiled exe's - (all of which work fine
under the emulator)

old compiles still transfer across and work fine, so it's nothing
strange with ActiveSync

any ideas?

I've tried unintalling everything and re-installing everything, and
even installed in all fresh on a different PC with the same results

In fact that seemed to make things worse as it then had problems even
knowing the targetting of the device, and even the samples wouldn't
compile straight with tinkering with the settings (a definate sign
something is badly wrong)

I was about to get the VS2005 properly now it's out, but I'm somewhat
hesitant until I can understand what's suddenly happened.

TIA

bob,

The rest of us got rid of beta 2 as soon as the RTM version of VS 2005 was
available to us, so I doubt we'll be able to be much help. I'd suggest
installing the RTM version of VS 2005 on a clean machine and see if you
still have the problem.

VS builds to a THUMB target by default - which doesn't work on 2003
phones. change the linker /MACHINE option to ARM.

does THUMB work on WM5 devices?

i hear that THUMB code is smaller and runs faster, is that correct?

it's smaller, havn't tried a speed test myself.

I've never heard that it is faster, but it probably is for certain cases.

THUMB is generally used when space is more important than the speed
sacrificed ; since many PDA applications aren't limited by CPU speed the
tradeoff is often acceptable. I think I heard somewhere that the *average*
THUMB program is generally about 75% the size of the equivalent ARM program;
even though each THUMB instruction is half the size of ARM, you have to use
more of them often enough that you do not get a 50% reduction in code size.

Note that this is only reducing your *code* size. So you can fit more programs
on the device, though you may not be able to run many more simultaneously.
