In project.reg I have add some key and value as below
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\CTR]
   "Prefix"="CTR"
   "Dll"="CardDriver.dll"
   "Order"=dword:1

And in my source code declare the init function as

DWORD
CTR_Init(
    PVOID Context
    )
{
        RETAILMSG(1,(_T("CTR_Init")));
        DEBUGMSG(1,(_T("CTR_Init")));
}
But I can’t receive the message “CTR_Init”, what’s wrong with it ?
Thanks for your help.
