Get the number of Pocket PC devices connected to my PC

Hii... I want to find out the number of Pocket PC devices(In my Case they are RFID reader's).Is there any way to do thi using RAPI in C#.net?can you开发者_StackOverflow please help me out....

There can only be one device connected to your PC at any time. So you only need to check if a device is actually connected. See here for example. I also recommend to have a look at OpenNetCF RAPI.

Only one device (PocketPC) can be connected at a time via ActiveSynch.

is it now possible to do this with RAPI2?

msdn says yes...but I don't get it working.

For Windows CE 5.0 and earlier, this enumeration sequence will only contain a single connected device.
