6. WIA Items And Properties
WinHEC 2006
4/22/2017
WIA Items And Properties
WIA “items” are used to represent both device attributes and device data
Two kinds of items
Applications use IWiaItem(2) (application items) – each application has its own “item tree”
Drivers use IWiaDrvItem (driver items) – there is only one “driver item tree” per device
Where do IWiaDrvItems come from?
IWiaDrvItems are created by the driver using WIA helper functions

8. Stream-Based Transfers
WinHEC 2006
4/22/2017
Stream-Based Transfers
IWiaTransfer for stream-based data transfers
Not required to support legacy transfers to get a logo
Legacy applications will still work via the compatibility layer
Implement the code for data transfer in drvAcquireItemData
Check the lFlags parameter for WIA_MINIDRV_TRANSFER_DOWNLOAD. If true, the transfer is stream-based
Call QueryInterface on the minidriver callback, requesting IID_IWiaMiniDrvTransferCallback
Call IWiaTransfer::GetNextStream to get an IStream interface, and write data directly to that interface via IStream::Write
Send progress messages, such as WIA_TRANSFER_MSG_END_OF_STREAM, via IWiaTransfer

9. WinHEC 2006
4/22/2017
Multi-Page Transfers
Multi-page transfers are supported with IWiaTransfer
Drivers needs to call IWiaTransfer::GetNextStream to get streams for the next pages
Drivers should call GetNextStream in a loop
S_OK to indicate another page has been requested
Multiple files can be produced by this method – the application requests the file types, and each page can represent a file; Previously a single transfer resulted in a single file
For multi-page TIFF files, request a single stream and write all the pages to the stream
For multiple file transfers, request a stream for each file

IWiaItem2 and IWiaItem support the preview filter
Windows Vista has a WIA Compatibility layer to ensure that
Windows XP applications (IWiaItem) work with Windows Vista drivers
Windows Vista applications (IWiaItem2) work with Windows XP drivers

13. Windows Vista WIA Driver Implications
WinHEC 2006
4/22/2017
Windows Vista WIA Driver Implications
New functionality enables
Simplified driver development in many areas e.g., data transfers
Looser coupling between value-add components
Example: Core driver functionality (data transfer, property negotiation) and enhanced functionality (Image Processing, Segmentation) can be separately implemented
Recommendation: Write separate drivers for older WIA (Windows XP and Windows Server 2003) and enhanced WIA (Windows Vista) functionality
WIA drivers developed for Windows XP and Windows Server 2003 will continue to work on Windows Vista but will not be able to expose enhanced WIA functionality (e.g., image segmentation, live preview, error handling)
Therefore it is easier to have separate drivers and install different package depending on operating system

Security Context Change
File system access
Under LocalSystem in Windows XP, driver had Read/Write access to almost any directory
Under LocalService, driver has mainly Read access only
If driver only reads files, then usually not a problem
Drivers should create or write their private files in the %userprofile% directory
Note: The user account in this case is “LocalSystem” or “LocalService”

Use the correct namespace when specifying the object name e.g., Global\MyDeviceLock
Set the object permissions correctly when creating the object
Don’t rely on default permissions

Security Context Change
Out-of-process COM components
Require two types of permissions
Launch permissions
Access permissions
Ensure the permissions on the COM objects are set correctly
Use the COM supplied method of storing your permissions under the AppID key
Call CoInitializeSecurity with the EOAC_APPID
This allows administrators to adjust permissions if necessary

Creating and opening processes

In Fast User Switching or Terminal Services environment, it is often difficult to say who the “user” is
In Windows XP, driver could launch the process under the incorrect account
Generally not possible under LocalService account, unless
Activating an installed COM component
Windows NT service etc
