Hi,
I read the following paragraph from
http://www.microsoft.com/hwdev/tech/network/netpm.asp:
£½£½£½£½£½£½>
Wake-on-LAN can be enabled by the end user in the Device Manager
properties page for the network adapter, or programmatically using
the WMI calls. The following two globally unique identifiers (GUIDs)
that can be used for this purpose correspond to settings in the
Device Manager property page:
GUID_POWER_DEVICE_WAKE_ENABLE (corresponds to the first check box
in figure 1) turns wake-up capabilities on the device on or off
GUID_POWER_DEVICE_ENABLE (corresponds to the second check box in
figure 1) can be used to enable and disable power management for
the device
The buffer of WMI request will contain TRUE or FALSE to turn
these features on or off. Every time these values are changed,
they will be recorded in the registry, so that they are
preserved from session to session. More granular settings can
be enabled by implementing vendor-specific property pages
for the device.
<===============
In my miniport driver, I implement a Custom OID mapped from
“GUID_POWER_DEVICE_WAKE_ENABLE” .
The driver has no .mof file.
The Custom OID is not called when I change the selection in
NIC Device Manager property page for Power Management.
I was puzzled with this problem for several days. Can somebody
give me a way ?
Thanks for your help,
Yee
