Ethernet debug from VS2005

I installed my CE 6 SDK based on a specific platform configuration (built before with PB).
Then I developed a C++ application running on my SDK. It runs correctly (copying the exe file into the embedded system), but it would be very helpful if I could running it in debug mode! Generally, it would be useful to download it by network.
I tried with ActiveSync, but it doesn't work (honestly I didn't understand so much about it...).
Any advice will be very appreciated!
