You can use ADOCE for that, but there is no C++ wrapper available. You will have to write your own or wait until I port Carlos Antollini's classes. Regards, João Paulo

BTW ADOCE used with C++ is unsupported from MS, just to let you know. MS suggests to use OLEDB with C++ under CE
besmel wrote: BTW ADOCE used with C++ is unsupported from MS Yeah, they do say a lot of crap... ADOCE is supported by C++ and in more than one way: you can either use the
#importdirective or generate the necessary header files with MIDL. It's all there. besmel wrote: MS suggests to use OLEDB with C++ under CE Sure, we are talking performance here (and I also prefer it). But in the support groups I've seen a lot of people asking for ADOCE C++ support, and that's what I'm planning to do in an upcoming article. Regards, João Paulo -
Ok, thanks!! I'll take a look at it :-)
The Virtual Office Systems classes are very basic. When I first tried them, I had to make major changes before I got them to do what I wanted. Eventually, I wrote my own. Regards, João Paulo

Joao, When I say it's unsupported doesn't mean you can't use it. The problem is if you need assistance or you ask for a pay per incident support. In this case you get that the tools you used (ADOCE C++) are unsupported and you get stucked... that's all

That's why there is a CodeProject: we can always find help with each other. ;) My small rant with MS is that they tend to say a lot of things that are not accurate and tend to send developers away from interesting things, like this one. I've been successfully using ADOCE for over a year in my projects. The OLE DB option is now up because I do really need the extra performance. Regards, João Paulo

Hi, I need to read and use a database on PocketPC using embedded visual C++ 3. This is an Access database. What are the classes that are supported and that I can use? I really don't know wich direction to choose, so any idea is welcome! Thanks

Hi, How to check that the #import directive in ado.h is correct for my development environment. Awaiting for your reply. Thanks, Siva

Find the
adoce31.tlbfile and make the#importdirective point there. If you do not have this file on your PC, download it from Microsoft Website (search for ADOCE 3.1) and install it. Regards, João Paulo
