Reference to the driver into PropertiesSheet

NTDEV
1

Hi all,
now i have the driver that supports multiple instances. (Thanks to everybody
replied my msgs...).
My driver has a related DLL to support a custom PropertiesSheet in the
DeviceManager.
How can point to the correct instance starting from the data arriving to the
PSProvider() function ?

Thanks !

Hi,
i need to know how to retrieve the index of the current instance of the driver
selected on the Device Manager applet.
Until the driver was a single-instance driver i read always in the following way
(inside my custom DLL) :

if (RegOpenKey(HKEY_LOCAL_MACHINE,
“SYSTEM\CurrentControlSet\Services\RemSer\Enum”, …

if (RegQueryValueEx(svcKey, “0”, NULL, NULL, NULL, &valSize) !=
ERROR_SUCCESS) …

But now the driver is multiple-instance and i must discover in the DLL which
instance i’m pointing, starting from the data passed to the DLL.
Can anyone can help me ?
Thanks !
