Accessing a local database from C#

Hi everyone,

I am pretty new to C# developing form mobile devices. I have an Access
database that I have syncronised through ActiveSync to my PocketPc. Now,
using VS.NET 2003 I want to develop a simple app that retreives data from
the database.

Is this possible at all, or do I need SQL CE server? Where can I find this
server?

Are there any samples on how to acess an Access database?

Thanks, from Spain
 
Sorry, I should have looked more carefully... I already know where to get
ahold of SLQ CE.

But I still don´t know how to use my Access imported Databases.

There is no inherent Pocket Access class library. InTheHand has one.

If it´s not supported by .Net framework, what's the point on having Access
databases in the Pocket PC? You can´t open them, not even programatically???
I don´t understand.....

You can use eVC just fine, there's just no managed provider. The "point" of
having it is for backward compatibility. Pocket Access as a data engine
will become obsolete in a future version of Pocket PC.
 
So... what will the data engine be?

So I'd be better off using XML or SQL as a data provider...

Thanks for the explanations, some stuff is pretty obscure for me...

I might as well... I guess I´ll decide when I see the amount of data to be
handled.

Data size is a key issue to use XML file as data source.
When you read from XML file will take much more time than
writting to it.

You can try yourself for experiment.
