IWMPropertyVault::CopyPropertiesFrom method (wmsdkidl.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The CopyPropertiesFrom method copies all of the properties from another property vault to this one.
Syntax
HRESULT CopyPropertiesFrom(
[in] IWMPropertyVault *pIWMPropertyVault
);
Parameters
[in] pIWMPropertyVault
Pointer to an IWMPropertyVault interface.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The method is unable to allocate memory needed to copy. |
Remarks
Passing NULL as pIWMPropertyVault will result in unpredictable errors.
CopyPropertiesFrom makes calls to other methods of IWMPropertyVault. Because all of the data is coming from the objects themselves, no errors should be returned from the other methods. A return code that is not in the table indicates the corruption of data in the property vault from which you are copying.
