摘要:
POS device statistics information is managed such that the information is available commonly without the device being claimed by one application during retrieval of statistics information. A helper class DeviceStatistics object facilitates storing of statistics information in a common statistic repository that may be hardware based or software based, for example an XML file. The helper class also facilitates retrieval and forwarding of the statistics information to a managing POS application employing a service object for the POS device. A Windows Service based statistics service is used to retrieve the statistics information from the common statistic repository and generate performance monitor counters. The performance monitor counters are provided to requesting applications.

Automatic interoperation functionality for legacy POS service and control objects is provided. In response to a request for creating an instance for a control object that implements an interface for the POS device, a legacy interoperability subsystem determines a unique identifier associated with the control object. The legacy interoperability subsystem dynamically generates an in-memory proxy class, based on the unique identifier. Thereby, the legacy subsystem enables the POS service application and the POS device to communicate with each other without having to instantiate one or more proxy classes for each instance of the legacy control object.

The present invention provides Plug and Play (PnP) functionality for devices that are not supported by an operating system. In response to the installation of an unsupported device, the operating system sends the event to a device manager application residing in user mode code. Upon receiving the event, the device manager application automatically installs the supporting configuration entries and software. After the device is installed, the device is accessible from an application without requiring any programming changes. Events are exposed to the application through a through a common control library (CCL). The library is directed at providing a generic interface for accessing the devices. Using the CCL the registered applications may receive events associated with the device.

The deployment of multiple embedded operating system components provides a designer with flexibility when customizing an embedded operating system for a target computing device. The embedded operating system components provide extra features to expand the functionality of the target computing device. The ease with which the designer may select various embedded operating system components to deploy from an originating computing device to the target computing device simplifies the design process. Configuration data of a core embedded operating system and configuration data of the deployed embedded operating system components are merged and any conflicts between configuration data are automatically resolved without rebooting the target computing device.
摘要:
A host operating system (e.g., WinPE®) detects hardware devices connected to a computing device and stores identifiers (if any) of detected hardware devices in a datastore (e.g., the WinPE® registry). Without performing a detection process, a setup program accesses the datastore to obtain identifiers of hardware devices attached to the computing device. The setup program uses a mapping file (which maps hardware devices to drivers of a set of driver files) to determine which drivers of the set of driver files are usable by the detected hardware devices. The setup file then installs the “selected” drivers into the computing device.
