Thus, two code blocks can be independent of each other, but together fulfill the needs of iterating and generating a series In this example, it might seem like overkill to use a code block, but you will quickly realize that using code blocks is a great way to process data sets For example, we have all encountered loops embedded within loops Very quickly in this situation, the code becomes complex and hard to follow Using code blocks, you can separate the code, and the embedded loops within loops are reduced to smaller, easily understood code chunks Code blocks have an advantage in that they can process single results, multiple results, or no results Looking at the implementation of GenerateSeriesSquared at the beginning of this recipe, an array is returned to the caller regardless of how many numbers are generated.

now bundled with previous patches, so many of the updates are fairly substantial in size, which can chew through your bandwidth. If you have another vehicle to deploy the Microsoft patches (like Jamf or ARD), you can disable AutoUpdate using the defaults command to write the HowToCheck key into the com.microsoft.autoupdate.plist file as follows:

Each MenuItem will display in the BlackBerry menu. To keep these class definitions compact, they call helper methods to perform their actual tasks.

defaults write com.microsoft.autoupdate HowToCheck -string "Manual"

The caller has to query the array and figure out if any numbers have been generated In contrast, using a code block, the callback will be called only when a number is generated The following code shows a more formal way of using a code block Source: /website/ROOT/ajaxrecipes/javascript/codeblockshtml function CustomList() { thisarray = new Array(); } CustomListprototypeiterate = function( callback) { for( item in thisarray) { callback( item); } } CustomListprototypeaddItems = function() { for( var c1 = 0; c1 < argumentslength; c1 ++) { thisarraypush( arguments[ c1]); } } In the example, a CustomList class is being defined The custom list has two functions: iterate and addItems The addItems function is used to add an item to a list, and the iterate function iterates each of the elements in the loop and calls a callback.

Similarly, you can push out the com.microsoft.autoupdate domain prefs through MCX, Apple s built in client management system (discussed further in 7). You ll find this preference file at ~/Library/Preferences/com.microsoft.autoupdate.plist

private MenuItem goItem = new MenuItem("Go", 0, 0) { public void run() { go(); } }; private MenuItem stopItem = new MenuItem("Stop", 0, 0) { public void run() { stop(); } }; private MenuItem doneItem = new MenuItem("Return", 0, 0) { public void run() { close(); } }; public RecordingScreen(int type, String location) { this.type = type; this.location = location; status = new LabelField("Waiting"); add(status); dataOut = new ByteArrayOutputStream(); initMedia(); }

Microsoft Entourage s Sync feature can be a bit problematic for certain environments. While administrators can disable the feature, users often simply turn it back on. But you can turn it off programmatically if you wish. The settings are stored in ~/Library/ Preferences/com.microsoft.entourage.syncservices.plist. To read the contents of the com.microsoft.entourage.syncservices domain, use the following command:

We initialize the media objects when first constructing the screen. As a result, the media operations are executed on the main thread and not a separate thread. Some Player methods, such as starting and stopping, are asynchronous, so you can safely call them from any thread without delay. Other operations, like the realize() and prefetch() that implicitly occur when you first call start(), block until they complete. This may seem dangerous to astute readers, as blocking operations should be called from a separate thread. Fortunately, BlackBerry devices do not delay long when starting capture, so you can safely fudge the rules here. This is handy, because you need to start your VideoControl before you can obtain the Field, and you must add your Field to the screen from the main UI thread. In other words, doing these tasks synchronously greatly simplifies the code. You ll see examples of handling media on separate threads in 3.

Your results will be similar to the following:

The callback parameter represents a code block An example of using CustomList is as follows..

{ "sync "sync "sync "sync } calendar" = 1; contacts" = 1; notes" = 1; tasks" = 1;

public void initMedia() { try { switch (type) { case RECORD_AUDIO: player = Manager.createPlayer("capture://audio"); player.start(); break; case RECORD_PICTURE: case RECORD_VIDEO: player = Manager.createPlayer("capture://video"); player.start(); video = (VideoControl)player.getControl("VideoControl"); cameraView = (Field)video.initDisplayMode( VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field"); add(cameraView); break; } player.addPlayerListener(this); state = STATE_READY; status.setText("Ready"); } catch (MediaException me) { status.setText(me.getMessage()); } catch (IOException ioe) { status.setText(ioe.getMessage()); } }

The above is an array with boolean values for each item. Changing the 1 s to 0 s will disable syncservices. To do this, you would use the following command:

We add the appropriate MenuItem objects to the menu based on the current state of the application. For example, Go will only display if we are in the READY state.
