Yes. You have to declare this function in order to trap COM errors. This function will only be declared once. You can use the following:

void __stdcall _com_issue_error(HRESULT m_hr)
{
	TCHAR pcszError[1024];

	_stprintf(pcszError, TEXT("_com_issue_error(%ld)\n"), m_hr);
	OutputDebugString(pcszError);
}

I'd avoid _bstr_t altogether. Use ATL's CComBSTR. It's smaller.

Can't establish connection to Pocket PC

I first had an older iPaq connected via it's cradle/usb. I went out, bought a new iPaq, installed ActiveSync 3.7 (after un-installing 3.5), now Visual Studio .NET 2003 can't establish a connection to the new iPaq.

What's with that?

Thanks!

Does ActiveSync 3.7 see your new iPAQ?

Aroogala9-Jul-03 6:51

Yes it does, however vs.net 2k3 does not. It did see it when I was using my old iPaq w/ AS 3.5. I uninstalled that and installed AS 3.7 to accomodate w/ my new iPaq.

Now vs.net won't recognized my pocket pc device. This means I don't have debugging capabilities, which really, really bites. WTF | :WTF:

Thanks!

... and reinstalling vs.net must be out of the question, right? Try to ask this question in www.pocketpcdn.com. There is a .Net-specific forum. Good luck!

Connecting to Pocket access from eVC++

It's not entirely out of the question, however that's not something I'm at all interested in doing. There is no guarantee that it will solve the problem and it may end up causing new and unexpected problems that I don't have time to deal with right now (big deadlines coming up.)

Thanks, I'll try the folks there.

Hi all,

Can any one tell me how to connect to pocket access database and execute commands.I am using eVC++.

Mahesh

João Paulo Figueira6-Jul-03 23:05

Try using ADOCE. The type library is available in the adoce31.tlb file. You can use the #import directive on this file.

There is an article on the Database section on creating ADO classes. You can adapt it to ADOCE. There are a number of database resources here: Pocket PC Developer's Network[^].

Hi, Thank you for helping me before( i speak about CDC Smile | :)

).
Now i have another problem - this time with database. I've red a lot of materials about databases on Pocket PC, but still have some problems, for example where can i find this file : adoce31.tlb. And another one question - i've loaded one example of database using with ADO, and can't execute it on my Pocket. Thank you very much.

I believe this file was available on older versions of the Pocket PC 2000 and 2002 SDK. Check this:

Missing ADOCE31.TLB?[^]

If you are using Pocket PC 2003, the cdb file format has changed. You will have to re-synchronize the mdb file.

I really don't know i only know the version of Windows it is 3.0. I used Embeded 4.0 but programms i wrote didn't worked on my Pocket PC. And then i started to use Embeded 3.0. And everything was ok until i started to think about database Smile | :)

. I hope this information will help Smile | :)

. Thanks.I really appreciate your help.

João Paulo Figueira9-Jan-04 7:16

You are definitely using Pocket PC 2002 and AdoSample should work just fine. Maybe you did not install ADOCE on your device. See how here:
