Thanks Erel.
What I was hoping to do was write a desktop tool to synchronize with more than one device. It would have been good to be able to identify them by name (like Activesync does) so the user can set synchronisation settings by device. eWallet by Ilium also does this, so there must be some trick that I'm overlooking.
In fact, I've just looked, and in the registry on the desktop at
HKEY_CURRENT_USER\Software\Microsoft\Windows CE Services
there are items that show the currently (or most recently) connected device's OEM name.
At
HKEY_CURRENT_USER\Software\Microsoft\Windows CE Services\Partners
there is a list of paired devices, with the "activesync" name for each. I just need to figure out how to decide which partner is connected.
Nearly there
