The Delete method removes an object or objects from a storage medium on a media device.
Flag that must always be set to WMDM_MODE_RECURSIVE by the client. If the object is a folder, it and its contents, and all subfolders and their contents are deleted. If the object is a file, this parameter is ignored.
Pointer to an application-implemented IWMDMProgress interface that enables the application to receive progress notifications for lengthy Delete operations.
The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:
- Standard COM error codes
- Windows error codes converted to HRESULT values
- Windows Media Device Manager error codes
This method permanently removes the object(s) from the storage medium.
When using a CompactFlash card reader/writer with Windows Media Device Manager service provider, calling IMDSPObject::Delete immediately after IMDSPObject::Write sometimes fails. This happens because data written to a CompactFlash reader/writer is buffered by the driver of the card reader/writer. The service provider responds as if the write operations are finished, but the driver writes them out to the device according to its own schedule. IMDSPObject::Delete fails if the driver has not finished its writing operation.
This method must be implemented. It must not return WMDM_E_NOTSUPPORTED or E_NOTIMPL. For more information, see Mandatory and Optional Interfaces.
