Abstract: Techniques relating to progressive data downloading are described. In one instance, a system includes an application configured to utilize data blocks to display content in a user-interface. The system also includes a progressive download component configured to retrieve specific data blocks from a data container responsive to requests from the application.

Abstract: A system and method are provided for implementing a content viewer for fixed-format documents. An existing document may be “published” to create a fixed-format document using the user interface of the exiting document's native application. The content viewer is integrated into an application program interface, reducing the burden of software maintenance and enhancing security features. The content viewer invokes a web browser, which provides a host environment for the viewer to display the published document.

Abstract: Network connectivity management can manage (e.g., harmonize) network connectivity services and network connectivity modules. By way of example only, network connectivity management is applicable to connections to a network through a network connectivity service via a network connectivity module. In a described implementation, network connectivity configuration information is scanned to locate data that corresponds to a preferred network connectivity service for a given connection scenario. The network connectivity module used in the given connection scenario is extracted. It is detected if the extracted network connectivity module is a preferred network connectivity module that is associated with the preferred network connectivity service. If not, the connection scenario can be redirected away from the non-preferred network connectivity module and toward the preferred network connectivity module. A user may optionally be given an opportunity to elect to connect via the preferred network connectivity module.
