Abstract: Systems and methods are disclosed in which a self-describing file is generated and utilized to provide applications with the ability to properly preserve unknown file content. A self-describing file may contain, or be associated with, an extension section that provides information that an application can use to properly calculate unknown file content. The extension section may include functions of formulas that the application can use to calculate values for data that the application would not otherwise support. This allows for the content of the self-describing file to be modified by an application that does not support all of the capabilities of the file while maintaining the integrity of the file and user experience when the file is subsequently accessed by a full featured application.

Abstract: An apparatus and method for operating a touchscreen device using a device having a rigid or semi-rigid body composed of an exterior side and a hollow interior side. The interior side is sized to receive and substantially surround at least a portion of a finger of a user. One or more contact points are provided on the exterior side of the body element, wherein each contact point when placed into contact with a touchscreen device provides an electrical charge to the touchscreen device making it able to manipulate at least one element on the touchscreen. In certain non-limiting aspects, the device takes the form of a shape, design, animal, humanoid, non-humanoid, object, character, or the like with the contact points being one or more aspects of or protrusions from the device.

Abstract: Methods and systems for associating two objects in a drawing application with one another are provided. Embodiments of the invention are directed toward a method in a computing environment that includes receiving a command to designate a target and designating the target. The method can further include identifying a subject and providing a suggested association of the subject with the target. The method can still further include receiving a command to accept the suggested association and associating the subject with the target as suggested.

Abstract: A facility for enabling the use of user-defined function in a spreadsheet document made up of cells is described. The facility receives a trigger to evaluate cells that include a distinguished cell. In response to receiving the trigger, the facility determines that the distinguished cell contains an invocation of a user-defined function. In response to determining that the distinguished cell contains an invocation of a user-defined function, the facility applies the user-defined function defined in the second cell to both (a) determine a result value for the invocation of the user-defined function and (b) from the determiner's old value, obtain a value for the distinguished cell.
