IPortableDevicePropVariantCollection::Add
The Add method adds an item to the collection.
Syntax
HRESULT Add( const PROPVARIANT* pValue );
Parameters
pValue
[in] Pointer to a new PROPVARIANT object to add to the collection. This method copies the PROPVARIANT to the collection, so you should release your local copy of the variable by calling PropVariantClear after calling this method.
Return Values
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
| S_OK | The method succeeded. |
Remarks
If a caller tries to add an item of a different VARTYPE contained in the collection and the PROPVARIANT value cannot be changed by this interface automatically, this method will fail. To change the collection type manually, call IPortableDevicePropVariantCollection::ChangeType.
Requirements
Header: Defined in PortableDeviceTypes.h
Library: PortableDeviceGUIDs.lib
