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.

A method and system for profiling execution of an application implemented by an application file comprising a plurality of data blocks. The application is executed in response to an execute command from a management process. Read messages are sent to the management process each time the application reads one or more of the plurality of data blocks of the application file. The management process records information about the read operations in one or more transcripts which may be used to create a streaming model for the application allowing the application to be downloaded using a conventional download protocol without using a specialized streaming protocol.
摘要:
Methods and systems for restricting the launch of virtual application files. A launching application is signed with a digital signature. When the launching application launches a runtime engine and instructs it to execute an application file, the runtime engine determines whether an entity identifier associated with the launching application identifies an authorized entity. If the entity identifier identifies an authorized entity and the digital signature is valid, the runtime engine executes the application file. A ticket may be transmitted to the launching application along with an instruction to launch the application file. The ticket includes a digital signature and an expiration date. The launching application communicates the ticket to the runtime engine, which will execute the application file only if the digital signature is valid and a current date is not later than the expiration date.

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:
Methods and systems for restricting the launch of virtual application files. In one embodiment, a launching application is signed with a digital signature. When the launching application launches a runtime engine and instructs it to execute an application file, the runtime engine determines whether an entity identifier associated with the launching application identifies an authorized entity. If the entity identifier identifies an authorized entity and the digital signature is valid, the runtime engine executes the application file. In another embodiment, a ticket is transmitted to the launching application along with an instruction to launch the application file. The ticket includes a digital signature and an expiration date. The launching application communicates the ticket to the runtime engine, which will execute the application file only if the digital signature is valid and a current date is not later than the expiration date.
