The previous example showed a simple installation that can be done easily. However, if you want to change the application in any way, you must move the application to each workstation if it s installed on multiple workstations. Also, you must include the DLL files that represent the custom activities created in 8. In the past, this has been the issue with most Windowsbased applications. Windows-based applications can have a rich user interface, but have been difficult to deploy. To correct this, Microsoft created the ClickOnce deployment technology and included it with VS2005.

The BitmapSource class provides a way of representing a single constant set of pixels at a known size and resolution. It is present in the System.Windows.Media.Imaging namespace, which requires you to reference the PresentationCore.dll file in your project. It s an abstract class from which many of the imaging classes you ll use derive.

Message and data integrity are very important to prevent such mischief The SSL protocol uses message authentication codes in the messages that are sent between Alice and the web site to make sure that no competitor or other malicious party can tamper with the data Availability: DVD-Factory may have a competitor that launches a DoS attack against the site in order that Alice will stop buying from DVD-Factory and instead come to their competing site As part of DVD-Factory s security strategy, its web site needs to be kept running and available 24 hours a day, 7 days a week One simple (but potentially expensive) approach that DVD-Factory might use to mitigate a DoS attack against it would be to overprovision their bandwidth to handle the increased traffic load caused by illegitimate clients.

You can read more about overprovisioning and other approaches to mitigating DoS attacks in Internet Denial of Service Attack and Defense Mechanisms, by Jelena Mirkovic et al Accountability: To ensure accountability, every time Alice places an order from the DVD-Factory web site, it produces a log entry so that Alice cannot later claim to have not ordered the DVDs This may sound a bit like non-repudiation, but it is actually accountability, since the goal is to simply keep a log of what Alice has and has not done Non-repudiation: It is possible for DVD-Factory to cheat and report that Alice ordered more DVDs than she actually did If the web browser and web site run a non-repudiation protocol, it is then possible for Alice to prove to a third party that she only ordered, say, 10 DVDs, and not the 12 that DVD-Factory may claim she ordered..

The BitmapImage class derives from the BitmapSource and is designed to be used easily within XAML. Using a BitmapImage is straightforward. The following is an example: <Image> <Image.Source> <BitmapImage UriSource="FishTn.JPG" /> </Image.Source> </Image>

ClickOnce deployment allows you to create a package that can be installed from a Web site that installs the application on the client. This could also be done in earlier versions of VS. What makes ClickOnce special is it allows you, as the developer, to set the package to look for updates. Using the update option on a ClickOnce package as a developer, you can make an update to the application and publish it. When the user of the application executes the application the next time, the package will recognize there s an update and ask the user to install it. This installation doesn t require administrator permissions on the workstation. The only exception to this is if the application has a prerequisite that isn t installed on the workstation. For example, the PurchaseOrderReceivedCheck application has a prerequisite of the .NET Framework 3. If a workstation doesn t have the .NET Framework 3 installed, an administrator must install it first. This architecture allows users to install an application to their desktop from a Web site, and when updates are available, the updates are delivered to their desktop automatically. For more information about ClickOnce deployment, see an article I ve written entitled ClickOnce Deployment with VS 2005 for the Web site ASPToday (http://www.ASPToday.com). Deploying a project with ClickOnce is easy. You can create the application as you normally would. Changes need to be made when the application is ready to be installed. Open the Solution Explorer and double-click My Project. This opens the project properties window. Click the Publish tab on the left side. The Publish screen looks like Figure 9-1.
