Well,the rectangle still doesnt show up.I need to access a variable from the first Dialog box that is available in the DoModal method.My code now looks like:
int CDexterDlg::DoModal(const int &refcUserInput)
{
// Initialization
m_UserInputDialogOne = refcUserInput;
return CDialog::DoModal();
}
void CDexterDlg::OnPaint()
{
CPaintDC dc(this);
dc.Rectangle(0, 0, 100, 50);
}
The variable m_UserInputDialogOne needs to be a dimension in the rectangle.Also,why isnt the rectangle with the numbers(constants) as paremters not showing up(ie as it is now in the code shown above)??!
Thank you very much!

Make sure the rectangle you are drawing is not covered by other controls.

Hello,
Another little question about Access database. I want to update the database of my PocketPC everytime I connect it to the PC.
So, for that I need to copy the database from my computer (wich is up to date) to my PocketPC. But I don't need all the tables within the database (just one).
How can I do such a thing ?? Are the files automatically transformed ??
Any idea is welcome  !

Use ActiveSync for that purpose. The setup will ask you what tables you want to synchronize.

Hi, yes I know but I need this to be done by code (this must be automatic and the client cannot acces that).

Really great !! 
Exactly what I was looking for !
It seems that I'll never find an end to your knowledge

noob question (tools: eVC++ w/ppc2k2 sdk)...
if header files are #include'd but the functions from their corresponding libraries never called, does the final compiled file include the unused functions thereby increasing file size?
fyi, the issue i'm trying to better understand is whether i #include windows.h or a subset.
tia..

Most of the functions declared in these #includes are implemented in DLLs. System DLLs are in ROM, so this is irrelevant for the final size of your application.

thanks and it makes sense for functions implemented in DLLs.
two followup ?'s:
1) what about the case where the unused functions are implemented in static libraries? are these unused fcn's compiled in even if they're not called?
2) is there a straightforward way when looking at the wince header files to determine if the api is implemented in a DLL or a static library?
thanks!

Depends on your linker, but the general answer is yes.

Unfortunately, no.

For #1:
The linker supplied with eVC will remove unused packages (called COMDATs in the documentation) if the /OPT:REF switch is turned on. This is turned on by default, unless the /DEBUG switch is enabled, in which case it's turned off.
To force the linker to remove unreferenced functions, the compiler must be instructed to package each function in its own COMDAT. You do this by specifying the /Gy option to the compiler (called 'Enable function-level linking' in the 'Customize' category of the Project Settings dialog).
If this option is not enabled, the linker can only include or exclude individual object files. A static library basically consists of multiple object files with a header describing what's in it.
From memory, Microsoft's static libraries are compiled with this option enabled.

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

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.

Ok thanks !
BTW, don't you have any sample code so I can start quickly ?
Thanks

BTW ADOCE used with C++ is unsupported from MS, just to let you know.
MS suggests to use OLEDB with C++ under CE

Yeah, they do say a lot of crap... ADOCE is supported by C++ and in more than one way: you can either use the #import directive or generate the
necessary header files with MIDL. It's all there.

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.

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.

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.

Find the adoce31.tlb file and make the #import directive 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.
