IPC via window messages or point-to-point messasge queues are pretty
much your only options.

Oh..

Is there any example about what you say? I'm a beginner and I really don't
know so much about IPC, etc

You really ought to search before you ask:

http://www.google.com/search?q=point-to-point+message+queue
http://www.google.com/search?q=window+message+IPC+compact+framework

First result in each will give you what you need.

Neil, you're right, I know but at the moment I was only looking for an
example, some code already written.. this is my need.

Thanks,

Click the links and the click through to first item in each result set
and you will find example code.

use #pragma managed/#pragma unmanaged in your C++ program(cpp) file.
in managed block you can make a function that do your .NET CF and then
call this function from unmanaged code.

Managed C++ is not a supported language for the .NET Compact Framework. So
this solution will not work.

Hope this helps,

so why I can still compile program with managed/umanaged code with Visual
Device Compiler??

Compile != run. The CF doesn't support all of the opcodes that managed C++
creates, so compile all you want, the CLR can't interpret all o the IL and
trying to run may fail. I say "may" becassue it's quite possible to create
a simple app in managed C++ that doesn't contain unsupported opcodes, but
there's no way to prevent it, so you will undoubtedly get to a point in any
real-world application where the opcode is used and the app will not work.
