getting unique device id from pocket pc
i want to get the 6 digit device code from my pda
i've heard that this 6 digit number i have is taken from a longer string of numbers, i was hoping it might be in the registry somewhere.
i've also heard that maybe a .dll will need to be used to grab the code from the device but i have no idea how to write them.
if anyone has the slightest of ideas, can they let me know

thanks

is there a system call for

GetDeviceUniqueID

?

p.s. and i think the UUID from which i get the 6 digit code from is a 32 digit code

the call to get the deivce id in c++ for windows api


        if (KernelIoControl(IOCTL_HAL_GET_DEVICEID, IntPtr.Zero, 
                                        0, outbuff, nBuffSize, ref dwOutBytes))
                                {
                                        done = true;
                                }

HAL = hardware abstraction layer

the method


        [DllImport("coredll.dll", SetLastError=true)]
                private static extern bool KernelIoControl(Int32 dwIoControlCode, 
                        IntPtr lpInBuf, Int32 nInBufSize, byte[] lpOutBuf, 
                        Int32 nOutBufSize, ref Int32 lpBytesReturned);

is there some way to do a similar thing with the system plugin?

very unlikly because your code have to run on the pocketpc device...

I had the same problem, trying to copyprotected our software for the pda.
Solved it by requiring a simple Licensekey for the pda (which is based on the DeviceID

i haven't tried using a dll yet, but is it possible to use one and then get a return value from it? i'll give it a go...
and the dll would have to run on the pocket pc would it?
