Re: VS2005 compatibility

Hi Paul, Thanks for your helping. Yes, I'm using CE 5.0. Would that message
be a generic one? I mean that other errors could also generate this message?

And the device that you are targeting is running Windows CE 5.0? I don't
see any problems with the header or the imports. The header is marked for
THUMB processor, Windows CE 5.0, GUI, all standard stuff for targeting
Windows CE ARM-based devices running 5.0 or later.

Hi Paul,

Attached is the ZIP of the problem EXE. Thank you.

If you're using a Web-based interface, I can't help you with attachments.
I'm using a real newsreader which has no problems with it.

You say "I can download the program to the target device to run it". So,
what happens if you try to run the problem program in the debugger?

I don't think I was using an emulator, because I can download the program
to
the target device to run it (first example) or copy the program manually
to
the device and run it.

As for the Workspace I mentioned, actually the two example are using the
same project "workspace". I just modified the _tmain() function to call
APIs
or use the CReg. So the project settings should be the same. They are
all
compiled successfully. The only differece is one can run and the other
not.
I don't know how to attached the exe here. I cannot find any other
options.

2. In this wizard, you adjusted things so that the targets listed are
just
your specific device?

Are you sure you're not building for the Colibri emulator? That would
be
an
x86 EXE, not ARM, as needed for the real device. Project settings are
not
attached to a workspace; they are part of the project. If the project
was
not generated as a Smart Device application, you've found your problem.

You can attach the EXE itself and I'll see what the headers look like,
but
the system works well, generally, so you're doing something way off the
track...

I must make some mistakes when typing the second examples, i.e.
ValueDW(),
instead of copying and pasteing the code. I think I did the same as
you
did
except my program cannot run. This is what I did.

1. Create a Smart Device project.
2. Remove the default device and select my device: Colibri.
3 Select Console Application. ATL, MFC and Empty project are
unchcked.
4. Then finish thw wizard. Everything is in default settings.
5. Then type in my code, compile and run with or without debugging.

These projects do not need additional libraries. But I don't know
what
default libs they use. So I don't think I change them. Besides I
use
the
same workspace and settings to compile the two examples, one can run
and
the
other doesn't. If that is not a problem from VS2005, would that
comes
from
BSP or its SDK?

And a thought arises. What libraries are you linking with? Did you
change
anything from the default generated by the VS2005 new project wizard
to
target Smart Devices?

Thanks Paul,

Here is the code without problems.

#include "stdafx.h"
#include <windows.h>
#include <commctrl.h>

int _tmain(int argc, _TCHAR* argv[])
{
wprintf(L"Starting...\n");

HKEY m_hKey;
int m_Index;
LPBYTE m_lpbValue; // last value read, if any

//TCHAR szValue[MAX_PATH];
DWORD ret = RegOpenKeyEx(HKEY_LOCAL_MACHINE, L"Comm", 0, KEY_READ,
&m_hKey);
DWORD dwValue = 1;
DWORD dwLen = sizeof(DWORD);
ret = RegQueryValueEx(m_hKey, L"BootCount", NULL, NULL,
(LPBYTE)&dwValue,
&dwLen);

ret = RegSetValueEx(m_hKey, L"Test", 0, REG_DWORD,
