Apple Remote Desktop possesses a network scanner that can detect machines via bonjour, by a specific IP address or by a range of IP addresses. Multiple Scanners can be set up, making it easy to rediscover DHCP machines on remote subnets. To create a network scanner, simply select New Scanner from the File menu. Name the scanner appropriately, and in the right hand pane, configure the scanner s settings. Options are Bonjour, Local Network, Network Range, Network Address, or File Import. These are mostly self-explanatory. Local Network searches subnets local to all interfaces on the machine. Network Range allows you to specify a starting and ending IP address, which is handy for scanning remote subnets. File Import allows you to import a file that has newline delimited subnet ranges. This is handy if you have rather intricate subnet configurations and want to capture multiple ranges in a single scan:

2 s exercise created an app that could capture media. There s a problem, though: how do you know if it s any good or not It would be much more useful if you could play back what you captured to make sure that your thumb wasn t over the camera and you can t hear the neighbors in the background. To get started, copy over your current version of MediaGrabber into a new project. Let s build on the previous version of the app, adding a media reviewer screen that plays back captured audio and video content. Listing 3-2 uses a separate class to handle display; this will allow us to support playing back arbitrary content in the future.

TIP: To list or to scan ARD has both static lists and dynamic scanners. If you find yourself coming and going from a network a lot, you will be much happier with a scan. If you are managing static IP addresses only, or have only a single subnet for all machines then lists are probably better suited. Lists are also better suited if you need to repeatedly target specific machines.

variable is a generic JavaScript object with no methods or parameters. The data member value is assigned dynamically to the default method. After the default has been assigned, the method example is overloaded with the three overloaded functions using the ops.overloaded function. Once the methods have been overloaded, they can be called with a varying number of parameters. The overloaded methods, for example, will then sequentially find the correct method to call. When implementing overloaded methods, keep the following points in mind: The overloaded method JavaScript generics expansion was similar to that shown in previous recipes. The only additional twist was the hard-coding of the parameter count. Using traditional programming practices, you would not do that, but using JavaScript generics it is trivial and recommended. When overloading methods, you need to provide a default implementation if you want it. You need to support not only the number of parameters to determine what you want to call, but also the type. This is a much more common use case, after all. A method that accepts a string could be overloaded by a variant that accepts an array and calls the string version for each element. Overloading methods is not possible according to types, but is made according to parameter count. You could implement overloaded types that filter on specific types. For example, you could implement an overloaded method filter that queries the presence of a specific object value. To do that, you can combine the proxy with the overloaded recipes.

Controlling machines is pretty straightforward. First, you must add client machines to your local database. To do so, use a scanner that you previously configured. The scanner will display found machines with a blue icon. Simply drag them to the All Computers container on the left. Once you have performed this action, computers listed in the scanner will have a blue icon next to them, as shown in Figure 7-27.
