| WPD_OBJECT_BACK_REFERENCES |
VT_UNKNOWN |
An IPortableDevicePropVariantCollection of type VT_LPWSTR indicating a list of ObjectIDs. When an object is referenced by a container object, for example, an audio object referenced by a playlist, the referenced object uses this property to refer back to its container object. The audio object may refer back to the playlist object in this example. |
| WPD_OBJECT_CAN_DELETE |
VT_BOOL |
A Boolean value that specifies whether the given object can be deleted. |
| WPD_OBJECT_CONTAINER_FUNCTIONAL_OBJECT_ID |
VT_LPWSTR |
The object ID of the closest functional object that contains this object. For example, a file inside a storage functional object will have this property set to the ID of the storage functional object. |
| WPD_OBJECT_CONTENT_TYPE |
VT_CLSID |
A GUID that identifies the generic type of this object, for example, a document or e-mail. This can be an object type defined by Windows Portable Devices, or a custom driver content type. The device object is the only object that does not report this property. |
| WPD_OBJECT_DATE_AUTHORED |
VT_DATE |
A value that specifies the date and time that the content was created. This might not be the same as the creation date of the file. For example, a music file has an authoring date of when the music was recorded, but a creation date of when the WMA file was actually created on the device. |
| WPD_OBJECT_DATE_CREATED |
VT_DATE |
A value that specifies the date and time the object was created on the device. |
| WPD_OBJECT_DATE_MODIFIED |
VT_DATE |
A value that specifies the date and time the object was modified on the device. |
| WPD_OBJECT_FORMAT |
VT_CLSID |
A GUID identifying the format of the object data. This can be a format defined by Windows Portable Devices or a custom driver format. |
| WPD_OBJECT_GENERATE_THUMBNAIL_FROM_RESOURCE |
VT_BOOL |
A Boolean value that specifies whether the thumbnail image for this object should be created from the default resource data.This provides a way for objects without a thumbnail resource to provide a friendlier browsing experience. Using this flag may affect the first display response, since the application must retrieve and calculate a thumbnail image from the device; it is more efficient to provide a separate thumbnail image resource, if possible.
|
| WPD_OBJECT_HINT_LOCATION_DISPLAY_NAME |
VT_LPWSTR |
If the given object appears as a hint location, this property indicates the hint-specific name to display instead of the object name. Drivers can specify location hints for various content types. These can be thought of as shortcuts to top-level folder objects that contain objects of the specified types. Clients that use these location hints can display a name for these shortcuts that differ from the folder's object name. If this property does not exist, the WPD_OBJECT_NAME typically is used instead. |
| WPD_OBJECT_ID |
VT_LPWSTR |
A string ID that uniquely identifies the object on the device. This ID need not be stored across sessions.If this property is both unique and persistent, the driver may set both WPD_OBJECT_PERSISTENT_UNIQUE_ID and WPD_OBJECT_ID to the same value.
|
| WPD_OBJECT_IS_DRM_PROTECTED |
VT_BOOL |
A Boolean value that specifies whether the media data is DRM-protected. If not present, this is assumed to be False. |
| WPD_OBJECT_ISHIDDEN |
VT_BOOL |
A Boolean value that specifies whether the object should be hidden. If not present, the object is assumed to be not hidden. |
| WPD_OBJECT_CAN_DELETE |
VT_BOOL |
A Boolean value that specifies whether the object can be deleted. |
| WPD_OBJECT_ISSYSTEM |
VT_BOOL |
A Boolean value that specifies whether the object represents system data (such as a system file). If not present, the object is assumed not to be a system object. |
| WPD_OBJECT_KEYWORDS |
VT_LPWSTR |
String containing a list of space-delimited keywords associated with this object. |
| WPD_OBJECT_LANGUAGE_LOCALE |
VT_LPWSTR |
A string thati dentifies the language used by a given object. If multiple languages are contained in this object, it should identify the primary language. This property may contain either a language code, as defined in ISO-639, such as: "en". It may also contain a language-country code, which consists of a language code of two or three characters as defined in the ISO-639 standard, followed by a hyphen, then followed by a country code as defined in ISO-3166, such as: "en-US". |
| WPD_OBJECT_NAME |
VT_LPWSTR |
The display name for the object. |
| WPD_OBJECT_NON_CONSUMABLE |
VT_BOOL |
A Boolean value that specifies whether this object is intended to be understood or merely stored by the device. If this property is not present, all data is assumed to be intended for consumption. |
| WPD_OBJECT_ORIGINAL_FILE_NAME |
VT_LPWSTR |
A string name for the file. |
| WPD_OBJECT_PARENT_ID |
VT_LPWSTR |
The object ID of the parent object. The only object that can return an empty string for this value is the root device object.To modify this property, call IPortableDevice::SendCommand (WPD_COMMAND_STORAGE_MOVE).
|
| WPD_OBJECT_PERSISTENT_UNIQUE_ID |
VT_LPWSTR |
A string ID that uniquely identifies the object on the device, similar to WPD_OBJECT_ID, but it must be stored across sessions.If the object identifier WPD_OBJECT_ID is both unique and persistent, the driver may set both WPD_OBJECT_PERSISTENT_UNIQUE_ID and WPD_OBJECT_ID to the same value.
|
| WPD_OBJECT_REFERENCES |
VT_UNKNOWN |
An IPortableDevicePropVariantCollection containing a collection of VT_LPWSTR object IDs identifying the referenced objects. This is only required if the object is a reference object such as a folder or playlist. |
| WPD_OBJECT_SIZE |
VT_UI8 |
The size of the object resource data. |
| WPD_OBJECT_SYNC_ID |
VT_LPWSTR |
An opaque string created by a client to retain state between sessions without retaining a catalogue of connected device content. |
