摘要:
A method of constructing a plurality of downloadable files from an application file and a plurality of transcripts. The application file stores data blocks and implements an application. Each of the transcripts stores at least one order in which at least a portion of the data blocks of the application file were accessed by the application when executed previously. The transcripts are combined into a combined transcript storing at least one combined order comprising a combined portion of the data blocks. The data blocks of the combined portion are arranged in a data structure having an origin. A first set of data blocks within a predetermined distance from the origin is stored in at least one initial execution file. A second set of data blocks outside the predetermined distance from the origin is stored in downloadable sequence files.

A method of modifying a virtual application configuration to include modifications made at runtime by a virtual application that is implemented by a first virtualized application file that was created previously using the virtual application configuration. At runtime, the virtual application implemented by the first virtualized application file stores modifications to its configuration in a sandbox memory location. The method includes reading the modifications from the sandbox memory location. Then, the modifications are written to the virtual application configuration. The modified virtual application configuration is then used to create a second virtualized application file that includes the modifications stored in the sandbox memory location.

A virtual process manager for use with a client application. Both the process manager and the client application are installed on a client computing device. In response to a user command to execute a virtual application at least partially implemented by a virtualized application file stored on a remote computing device, the client application sends a high priority command to the process manager to execute the virtual application. Before receiving the user command, the client application sends a low priority command to the process manager to download at least a portion of the virtualized application file. In response to the high priority command, and without additional user input, the process manager downloads any portion of the file not downloaded in response to the low priority command, and executes the virtual application on the client computing device. The client application may comprise a conventional web browser or operating system shell process.
摘要:
A method of hosting a first application (e.g., a virtual application) inside a second application (e.g., a control displayed by a web browser). The method includes executing the first application inside a runtime environment generated at least in part by a runtime engine. The executing first application calls user interface functions that when executed inside the runtime environment generate a first user interface. The runtime engine captures these calls, generates messages comprising information associated with the captured calls, and forwards the messages to a user interface manager that is a separate application from the runtime engine. The user interface manager receives the messages, translates the information associated with the captured calls into instructions for the second application, and sends the instructions to the second application. The control receives the instructions sent by the user interface manager, and displays a second user interface for the first application based on the instructions.
摘要:
A data structure including simple and complex objects. Each simple object includes a content type indicator, a size indicator, and one or more simple data types. Each complex object includes a content type indicator, a size indicator, and one or more child objects. The complex objects include a layer object having first and second child objects. The first child object is a collection of complex objects storing information for configuring a virtual filesystem of a virtual application at application startup. The second child object is a collection of complex objects storing information for configuring a virtual registry of the virtual application at application startup. Reading of selected simple and complex objects may be deferred at startup based on the content type indicator. Deferred objects may be read after startup when access to information stored by the deferred object is request by the virtual application.
摘要:
A method including downloading a streaming model file and at least one initial execution file from a server via a conventional download protocol without using a specialized streaming protocol. When executed, the initial execution file only partially implements an application. The model file stores information identifying additional portions of the application file to be downloaded from the server. Data is read from the initial execution file, and stored in a local copy of the application file. Then, the application is executed by executing the local copy. Until the entire application file has been downloaded and as the application is executing, the information is read from the model file to identify a next file to download, the next file is downloaded via the conventional download protocol without using a specialized streaming protocol, next data is read from the next file, and the next data is stored in the local copy.

A virtual process manager for use with a client application. Both the virtual process manager and the client application are installed on a client computing device. The client application is configured to receive a user command to execute a virtual application at least partially implemented by a virtualized application file stored on a remote computing device. In response to the user command, the client application commands to the virtual process manager to execute the virtualized application file. Without additional user input, the virtual process manager downloads the virtualized application file from the remote computing device and executes the virtual application at least partially implemented by the downloaded virtualized application file on the client computing device. The client application may comprise a conventional web browser or operating system shell process.
摘要:
A system and method for directing download and execution of an application. A runtime engine receives an identifier of a block of shared memory from a directing process. The shared memory stores a map indicating which portions of an application file have been stored in a local copy of the application file. The runtime engine also receives an instruction from the directing process to execute the local copy when the local copy stores less than the entire application file. As the application executes, the runtime engine identifies requests from the application to access portions of the local copy and uses the map to determine whether the requested portions have been stored in the local copy. If the requested portions are not stored in the local copy, the runtime engine prevents the executing application from accessing the local copy until the map indicates the requested portions have been stored therein.
