There is no file attribute with the value 0x because a value of 0x in the FileAttributes field means that the file attributes for this file MUST NOT be changed when setting basic information for the file. File systems silently ignore any attribute that is not supported by that file system. It is recommended that unsupported attributes be masked off when encountered.

What inspired this shift in strategy at Microsoft is the same impetus for organizations of all shapes and sizes striving to take advantage of the tremendous opportunities for interconnectivity offered by the web and the economies of scale rendered by platforms that embrace interoperability.

It gives the user tremendous flexibility. It brings together the best of the Web, the best of the desktop, and the best of the device always using the service as a hub. Indeed, for nearly a decade, organizations of all shapes and sizes have been applying service-oriented architecture SOA with varying degrees of sophistication and success.

Even where SOA has been successful, practitioners have traditionally been handicapped by the friction resulting from the non-interchangeable roles of client and service. For example, once a client learns the URI of a service endpoint, it consumes the service by making a request for which it either expects a response or no response at all in the case of a one-way or datagram exchange.

In order for the URI to be addressable and consumable by the client, the service must reside on the same network, or be routed to a different network via a traditional router or the Internet. The client can live anywhere and on any platform provided it can call a service over port such and such, but it is nearly impossible for a client living in a different network to call a service without some hosting or heavy infrastructure work that enables the endpoint to be exposed and consumed across a heterogonous network.

The Lazarus Effect Despite losing some of its luster due in part to the inherent complexity of middleware coupled with the insatiable need for our industry to oversaturate the market with hype and false promises, the need for SOA in composing solutions across the boundaries of the traditional enterprise has never been greater.

Chris Howard of Gartner Research agrees. One of the things that make Windows Azure so compelling is that it is built on a single unified platform: By applying similar techniques that have allowed chat software to traverse traditional boundaries inherent to modern networks software firewalls, hardware firewalls, routing challenges due to the lack of public IP addresses and proliferation of NAT and leverage the largest, most sophisticated and resilient network ever built the InternetService Bus democratized the ability to stand up a service from anywhere in the world, ushering in a new era of truly hybrid computing.

In a nutshell, Service Bus provides a highly robust messaging fabric hosted by Windows Azure that serves as a relay between two or more endpoints. A client and service or services establish an outbound, bi-directional socket connection over either TCP or HTTP on the relay and thus, messages from the client tunnel their way through the relay to the service.

In this way, both the client and service are really peers on the same messaging fabric. The service receives messages from the relay on behalf of the client and as such, the roles can easily be reversed.

To on-ramp Service Bus, the WCF developer need only choose the binding corresponding to the channel shape and protocols of interest.

This article is not an introduction to Service Bus or Relay Messaging as it is already a well-established product that includes key capabilities for exposing services beyond traditional trust boundaries.

Like most Enterprise Service Buses ESBsAzure Service Bus is the manifestation of a number of core messaging patterns that provide the ability to design distributed messaging solutions in a loosely coupled manner that promotes autonomy and separation of concerns.

As a result, the Service Bus is a key technology for enabling hybrid scenarios at the platform level i. It is important to note that the Service Bus is not a replacement for on-premise publish-subscribe messaging.

Introducing Queues and Topics in Azure Service Bus

It enables new scenarios that allow you to integrate your current on-premise messaging and provides the ability to compose clouds, be they your own, your partners or those of commercial cloud providers such as Microsoft.

Notice that the Service Bus is providing capabilities for integrating clients and services regardless of where they reside. For non-trivial SOA, on-premise pub-sub is a key capability for decoupling services and clients regardless of whether they reside on-premise or beyond.

Composing clouds with Azure Service Bus. Service Bus Brokered Messaging, including support for Queues and Topics, are built on this foundation.

A Common Distributed Messaging Scenario When building distributed systems, it is useful to design message exchanges in terms of publishers and subscribers or producers and consumers.

Publishers are clients which incidentally can be a traditional client or service also acting as a client that are either sending a request-response message and will wait for a response; or are sending a single, one-way message and expect no response typical in asynchronous messaging.

Subscribers care about these messages for one reason or another and thus subscribe to these messages. Figure 2 shows a one-way message exchange pattern.

A one-way message exchange pattern. Now, to make this a bit more concrete, consider a point-of-sale system. Purchases, be they on-line or at brick-and-mortar retail outlets, typically involve a point-of-sale POS client with which a cashier or system interact, which in turn interacts with a middle layer, which manages a number of services to fulfill a purchase order.

One of the first things a smart POS system does when a unit is sold is trigger an event that will update inventory on that product so that the company can make proactive, intelligent decisions about managing inventory levels.

In most cases, this is an automated administrative function, that is or should be transparent to the customer. Of course, this is just one of several things that likely need to happen when an order is placed. Credit card authorization as well as fulfillment whatever that means in the context of the purchase needs to take place as shown in Figure 3.MSDN Magazine Issues and Downloads.

The following attributes are defined for files and directories. They can be used in any combination unless noted in the description of the attribute's meaning. There is no file attribute with the value 0x because a value of 0x in the FileAttributes field means that the file.

For example, to grant the access permissions FILE_WRITE_ATTRIBUTES, FILE_READ_EA and FILE_WRITE_EA you add the associated values , 16, and 8. In this example, the value of AccessMask is Some values have different meanings depending on whether the AccessMask property is associated with a file or a directory.
