PnP-X Provider PKEYs

  • Artículo

[Function Discovery is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

A PnP-X provider is a type of built-in provider. The SSDP and WSD providers implement the PnP-X provider type and the PnP-X PKEYs, in addition to implementing protocol-specific functionality and PKEYs. The values associated with the properties named below are supplied by the device in metadata messages.

PKEY_PNPX_GlobalIdentity

The UUID of the root device. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_Types

The types of messages sent or received, as described in the device's discovery message. PROPVARIANT type VT_VECTOR | VT_LPWSTR.

PKEY_PNPX_Scopes

The discoverable groups of network endpoints providing services to the device. PROPVARIANT type VT_VECTOR | VT_LPWSTR.

PKEY_PNPX_XAddrs

A list of XAddrs provided in the Hello, ProbeMatch, or ResolveMatch messages sent by the device. PROPVARIANT type VT_VECTOR | VT_LPWSTR.

PKEY_PNPX_MetadataVersion

The metadata version. This is a non-negative integer that is incremented on metadata change. Metadata includes types and scopes. PROPVARIANT type VT_UI8.

PKEY_PNPX_ID

The unique identifier of the device. For root devices, this property has the same value as PKEY_PNPX_GlobalIdentity. PROPVARIANT type VT_LPWSTR.

Note

Devices cannot share an identifier, even if the devices use different protocols. If a device implements more than one protocol, the device must have a unique identifier for each protocol.

PKEY_PNPX_RemoteAddress

The remote address of the device. The address is only populated by the WSD provider when the device is discovered by directed discovery. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_Manufacturer

A human-readable form of the name of the device manufacturer. This string can be localized. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_ManufacturerUrl

The URL of the device manufacturer's web site. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_ModelName

A human-readable form of the model name of the device. This string can be localized. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_ModelNumber

A human-readable form of the model number of the device. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_ModelUrl

The URL of the page containing the description of the device model. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_Upc

A human-readable form of the device product code. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_PresentationUrl

The presentation URL for a web page that controls the device. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_FriendlyName

The display name for the device. This string can be localized. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_FirmwareVersion

The firmware version for this device. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_SerialNumber

A human-readable form of the serial number of the device. PROPVARIANT type VT_LPWSTR.

PKEY_PNPX_DeviceCategory

The device category. PnP-X categories are the namespaces in which components that provide similar base functionality are grouped.

Each category has predefined keywords associated with it. These keywords are used to restrict the list of devices displayed in the Network Explorer. When the user types one of the predefined keywords into the Search Category box, Network Explorer displays only the items in the matching category.

Some categories have predefined subcategories. A subcategory can be specified in the device metadata, and its value will be stored in the PKEY_PNPX_DeviceCategory property key instead of the parent category value.

Subcategories are not displayed in the Network Explorer. Instead, a subcategory's parent category value is displayed. Subcategories can be queried programmatically, but they cannot be queried by the end-user.

Providers can define and use their own subcategories, but they cannot define their own categories.

The following table shows the possible device categories.
