Abstract: A previewing system that permits selection from a plurality of interactive previewers for use in a system shell browser is disclosed. The previews may be extensible, such that different application developers may write custom previews for different file types, and the shell browser may follow established criteria to select an appropriate preview. The user may enter criteria to control which previewers are used for different situations, such as when certain file types are selected for previewing. Size of an available display area for the preview may be a criterion, such that resizing the preview area may cause a different preview to be displayed. The preview may be executed as a separate process from the browser so that crashes and hangs in the previewer process do not fatally affect the browser process. Previews may be incorporated within common file dialogs offered by an underlying operating system, such that different applications may share the common previewer.

Abstract: A binary theme file format provides optimized access to retrieve graphical component theme property data. The binary format includes data structures storing a set of defined visual characteristics for graphical component classes, parts, and states. The data structure includes a hierarchy of theme data. A theme manager quickly retrieves theme property data by indexing into the binary file with a unique theme handle. The theme manager accesses state, part, class, and global property sections to retrieve theme data. Jump tables and jump-to-parent references allow for quickly traversing property data sections. Packed data sections have packed objects having the necessary property data for frequently used graphical components. A custom image region data section provides border data for nontransparent image borders. A sampled colors section facilitates rendering of images with solid sections. The binary file format can be constructed using a text theme file and is loaded into shared process memory.

Abstract: A method for removing some or all metadata from files during copying or moving. Metadata management software may register with an operating system and be called to remove metadata crossing a trust boundary, such as going from a local hard drive to a file share.

Abstract: A system, apparatus, method, and computer-readable media are provided for specifying and editing the values of a multi-valued property. According to one method, a field is displayed for entering the values of the multi-valued property. A selection or alphanumeric characters may be received in the field. In response to receiving one or more alphanumeric characters in the field, one or more possible values for the field are identified based on the received alphanumeric characters. In response to receive a selection of the field, one or more suggested values for the field are identified. A menu is then displayed adjacent to the field. The menu includes the suggested or possible values and is presented in a manner that allows each of the values to be individually selectable as a value of the property. Multiple possible values may be simultaneously selected from the menu. Once the desired values have been selected, the selected values are inserted into the field.

Abstract: A method of communicating between a graphical component library and an appearance manager is provided that includes issuing a request, that includes component defining parameters, for rendering services by a graphical component library. The appearance manager receives the request for rendering services and assigns appearance characteristics to the graphical component based upon the provided parameters. A method of rendering graphical components on the display of a computer system is also provided that includes rendering the requested graphical component according to the appearance characteristics assigned by the appearance manager. A method is also provided for communicating between a graphical component library and an appearance manager that includes issuing a request that includes component defining parameters, for information about the defined component.

Abstract: A system and method are described that use theming functions of a theme manager to render graphical components in a themed fashion. The theme manager uses a theme file that has theme properties for graphical components of all types. When an application is started a system is provided that determines whether the application supports theming. If the application supports theming a dynamic link controls library that supports theming is linked to the application. If the application does not support theming, the non-theming controls library is linked. If an application supports themes, application user controls and shell common controls are rendered with themes by using the functions of the theming controls library that interact with functions of the theme manager. Non-client window components are rendered using themes by intercepting render messages to windows and sending the messages to the theme manager.
