Patent number: 8296779Abstract: Architecture that facilitates performance enhancement in message-based computing across a performance-based interface. When a request from a source is transmitted across the interface to a destination, a filter component in communication with the destination dynamically allows only one or more relevant responses from the destination to transition the interface to the source. This mechanism achieves an even tighter filtering of events while at the same time giving developers more flexibility over the events they choose to register, thereby enhancing the performance of message-based computing architectures by reducing unnecessary computation.Type: GrantFiled: February 3, 2010Date of Patent: October 23, 2012Assignee: Microsoft CorporationInventors: Seth M. Demsey, Christopher W. Lorton, Jamie A. de Guerre, David C. Wrighton, Katrina Schaeffer, Michael G. Boilen

Patent number: 8024729Abstract: This disclosure relates to drawing within a computer environment using a drawing resource. The computer environment includes a managed code portion and a native code portion. The computer environment compares a draw parameter call value being passed from the managed code portion to the native code portion with a stored drawing resource value stored in the native code portion. If the draw parameter call value is the same as the stored drawing resource value, then the computer environment is configured to draw onto a native drawing surface using the stored drawing resource. If the draw parameter call value is not the same as the drawing resource value, then a new drawing resource is created in the managed code portion. In another aspect, a portion of the drawing resource feature portion that contains data that describes at least one or more parameter of the drawing resource is transmitted between the managed code portion and the native code portion.Type: GrantFiled: July 2, 2007Date of Patent: September 20, 2011Assignee: Microsoft CorporationInventors: Seth M. Demsey, Tuan Huynh, Christopher W. Lorton

Patent number: 7802056Abstract: Techniques for management of drawing resources are described. In an implementation, a reference count numeral may be associated with a drawing resource stored in cache memory. One may be added to the reference count numeral each time a new drawing resource is added to memory. In addition, one may be removed from the reference count each time an existing drawing resource is removed from the memory. Also, the drawing resource may be maintained in the cache memory when the reference count numeral is greater than zero.Type: GrantFiled: July 2, 2007Date of Patent: September 21, 2010Assignee: Microsoft CorporationInventors: Seth M.

Patent number: 7546607Abstract: Notifications are generated in managed and native environments and propagated to an interfacing abstraction layer of native code there between. The abstraction layer assesses each received notification to determine whether the notification, or a previously received collection thereof, should be transitioned across a boundary between the managed environment and the native environment. The managed environment includes a virtual machine in a managed code portion. The native environment includes an operating system that interfaces the abstraction layer which is at a boundary between the managed code portion and the operating system. A collection of notifications are those that have been batched and/or synthesized. The abstraction layer is configured with predetermined criteria to assess whether to form a collection of received notifications and/or to prevent a transition of a notification, or collection thereof, across the boundary.Type: GrantFiled: November 19, 2002Date of Patent: June 9, 2009Assignee: Microsoft CorporationInventors: Seth M.

Patent number: 7281248Abstract: One aspect relates to a process and associated apparatus that implements a user interface (UI) control within a computer environment. The computer environment includes a managed code portion and a native code portion. The implementing the UI control includes creating a plurality of control node data structures within the managed code portion. A managed UI control is virtualized within the managed code portion by associating and/or batching at least two of the control node data structures. The UI control is realized in the native code portion by migrating the managed UI control into the native code portion. In certain aspects, the UI control is populated and parented prior to the realizing.Type: GrantFiled: November 19, 2002Date of Patent: October 9, 2007Assignee: Microsoft CorporationInventors: Seth M.
