Ordered binder document sections having different file formats stored within a binder file. The binder file maintains the order of binder document sections and the native file format of each section. The ordered sections can be viewed and edited through a viewport of a frame displayed by a binder program module. By selecting graphical images displayed in a selection area of the frame the content of a binder document section can be viewed and edited without viewing the content of other binder document sections. The graphical images can be icons or graphical images derived from the content of sections called thumbnail images. A thumbnail image can be derived from either the first page or from multiple pages of an individual section. The binder program module can also dispatch the underlying application program modules that created each binder document section to print, spell check, and grammar check the binder document sections as a single data processing task. In this manner, selected sections of a binder document can be printed as a single consecutively printed document without having other print jobs interrupting or intervening between printed sections of the binder document.

In a distributed computing environment, a message gate may be the message endpoint for a client or service. A message gate may provide a secure message endpoint that sends and receives type-safe messages. Devices may have a gate factory (e.g. message endpoint constructor) that is trusted code on the device for generating gates based on XML message descriptions. In one embodiment, the gate factory may construct a gate from the XML schema of the service, a URI for the service, and an authentication credential. Access to some services may be unrestricted. For such services, a gate may be constructed without an authentication credential, saving the overhead of running an authentication service and incorporating an authentication credential. Gate construction may also be optimized for certain clients that do not desire to perform checking of messages against a service's XML schema. If verification is not desired, a client may avoid or may chose to avoid building (e.g. by a gate factory) some or all of the gate code that checks the messages against the XML schema. Also, the building of a gate may be made lightweight by appropriate reuse or sharing of pieces used to construct other gates. Devices may maintain a cache of gates to avoid constructing them each time the same service is run.

Processing within a computing environment that supports pageable guests is facilitated. Processing is facilitated in many ways, including, but not limited to, associating guest and host state information with guest blocks of storage; maintaining the state information in control blocks in host memory; enabling the changing of states; and using the state information in management decisions. In one particular example, the guest state includes an indication of usefulness and importance of memory contents to the guest, and the host state reflects the ease of access to memory contents. The host and guest state information is used in managing memory of the host and/or guests.
