[COM ?] ActiveSync provider & POOM issues

Hello,

I'm currently playing with the PocketPC SDK 2003 and ActiveSync, in
order to use POOM. I've tried a very basic piece of code but it doesn't
work.

...
HRESULT hr = S_OK;
IPOutlookApp *pOlApp = NULL;

if (FAILED(CoInitializeEx(NULL, 0)))
{
printf("CoInitializeEx() failed !\n");
return FALSE;
}

hr = CoCreateInstance(CLSID_Application, NULL, CLSCTX_INPROC_SERVER,
IID_IPOutlookApp, (LPVOID *)&pOlApp);
if (FAILED(hr))
{
printf("CoCreateInstance failed : hr = %x\n", hr);
return FALSE;
}
...

When run, the result is :

CoCreateInstance failed : hr = 80040154

Taken from winerror.h, it means REGDB_E_CLASSNOTREG, or "class not
registered". Where does this error come from ? Do I have to registered a
DLL ? Or something like this ?

My setup is :
- MS Toolkit 2003 (compiler)
- PocketPC SDK 2003 (and eVC++ 4)
- ActiveSync 3.7.1

Thanks,

Damiano

Hello,

Thanks for taking time to look at my problem. Unfortunately, it still
doesn't work :(

I had already put the '#define INITGUID' in my code, I just didn't quote
it entirely. And putting COINIT_MULTITHREADED didn't have any effect.

What is strange is that IID_IPOutlookApp resolve to a CLSID not present
in the registry. As I'm no expert in Windows programming, I can't say if
it's a problem. May it be ? Is there an interface I can try, one that is
always present on a Windows system ?

Cheers,

Hello again

Did you try to define the "DEFINE_GUID" command in "pimstore.h" by hand. As i refer
there are comliler problems by interpreting the IID_IPOutlookApp parameter

The IID_IPOutlookApp is a Reference to the identifier of the interface to be used to communicate with the object. That is the Pocket Outlook Main Object

So try to define the DEFINE_GUID command by hand in the following manner

This is the current definition in "pimstore.h"

DEFINE_GUID (IID_IPOutlooApp, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?)

Try to define it that way

EXTERN_C const GUID IID_IPOutlookApp{ 0x?, 0x?, 0x?, {0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?, 0x?} }
It's the same because DEFINE_GUID is defined that way in "objbase.h" which is include
in your project

The interrogation mark represents a value which you find in "pimstore.h" where th
definition of IID_IPOutlookApp is made

(To find the definition of IID_IPOutlookApp mark the parameter by double clicking an
use the popup option "Go To Definition Of IID_IPOutlookApp" or any other way...)

If you don't do so, the error message looks like this

OutlookAccess.obj : error LNK2001: unresolved external symbol _IID_IPOutlookAp
X86EMDbg/OutlookAccess.exe : fatal error LNK1120: 1 unresolved external
Error executing link.exe
Creating browse info file..

Hope this will help you

Best Regards
Tobias

I suggest you use the registry editor to see if there is an entry for
[HKEY_CLASSES_ROOT\CLSID\{05058F23-20BE-11D2-8F18-0000F87A4335}] on the
device

Ensure there is at least InProcServer32 registry key with a default value of
pimstore.dll

If is it not there then you will need to register the PIMSTORE.DLL by
calling the DLLRegisterServer exported by pimstore.dll

It is also possible you might need to change your entry for
CLSCTX_INPROC_SERVER to CLSCTX_ALL.

Hello,

Thanks a lot Tobias and Paul for your precious help, but I know where my
problems come from : me and my sillyness ;-)

In fact, I thought that I could use the POOM API in *desktop* apps, like
a remote procedure call using PocketOutlook 'services' from my PC...

Apparently, what I need to do can be handled by a custom Active Sync
provider. My goal is to create a provider for data synchronization with
*Mozilla*, instead of Outlook. For users, it would only be a
drag-and-drop replacement of the 'outstore.dll' file. So I am trying to
'mimick'/copy the existing provider, and, as I've no experience at all
in PPC/Windows programming, that ain't easy !

Any suggestion is welcome :)

Cheers,
