Errata

The word 'that' is doubled

At times these fully qualified names?those that that
include the entire namespace

"then" should be "them"

At times these fully qualified names?those that that include the entire namespace?can become quite long, so it?s necessary to occasionally hyphenate THEN across line breaks, as in Windows.Security.Cryptography.CryptographicBuffer.convertString- ToBinary.

Hello,

Sub: A minor letter is missed during hyphenation,

Quoted Text in PDF:

"For the launch kind, another bit of information from the Windows.ApplicationMode.- Activation.ApplicationExecutionState enumeration tells the app how it was last running."

Errata Correction:

Printed as Windows.ApplicationMode instead of Windows.ApplicationModel

i.e (I first though as if there is something ApplicationMode instead of ApplicationModel)

Note from the Author or Editor:
It should be ApplicationModel

In: "(or initializer as it is more property called)" it should be "properly" instead of "property".

In: "(or initializer as it is more property called)" it should be "properly" instead of "property".

the template is defined in scenario1.html not default.html

The control?s item template is defined earlier in default.html with the id of smallListIconTextTemplate and is essentially the same sort of thing we saw with the FlipView (an img and some text elements), so I won?t list it here.

Note from the Author or Editor:
Good catch!

"and" should be "an"

This behavior will select or deselect and item, depending on its state, and then invoke it.

The word "apparently" should be "apparent".

The word "required" should be "requires"

"one" should go

For this reason the creation of CharacterGroupings is done one outside of the function.

"above" should be "below"

You can also see how this page assigns a handler to the itemInvoked events (above ready), calling WinJS.Navigation.navigate to go to the groupDetail or itemDetail pages as we saw in Chapter 3:

"copanion" should be "companion"

Here?s how the sample does it with two ListView controls (plus the template used for the zoomed-out view; I?m showing the code in the modified sample included with this chapter?s copanion content):

"stylealso" should be 2 words

The win-semanticzoombutton stylealso lets you style the zoom control button if needed.

win-top should be win-navtop

Note from the Author or Editor:
Yes, thanks for the correction.

2 times "already"

We?ve already seen the groupDataSource, groupHeaderTemplate, itemDataSource, and itemTemplate properties already.

"them" should be removed, or maybe it should be "then"

If you want to override styles for a ListView, be sure to scope your selectors them with other classes like .win-listview or a particular control?s id or class.

Note from the Author or Editor:
Omit "them"

"primarily" should be "primary" in

...how people in the home might move between primarily spaces...

"riles" should be "rules" in

...add a few style riles.

"this" should go

...handling view states for every page this does not mean...

"use" or "load", not both

Alternately, you can use load different graphics (through different img.src URIs) that are better suited for the most common screen size.

Note from the Author or Editor:
Should be just "load"

"his" should be "this" in

Be aware of his if you?re using the completed handler to process such commands.

"is" should be added

I think this exactly why many people enjoy traveling in a motor home!

"look" should be deleted

In fact, if you look open this file for the Sports app, as is shown in the figure, you?ll see a value like {"lastSuspendTime":1340057531501}.

Note from the Author or Editor:
Change to "If you look at this file"

"to" should be inserted

First, however, other APIs like URL.createObjectURL?working with what are known as blobs?make it possible to do many things in an app without having TO descend to the level of file I/O at all!

"an" should be inserted

This is also the only means through which AN app can access safe (nonsystem) areas of the file system without additional declarations in the manifest.

"with" should be "will"

(Attempting to obtain a folder without the correct capability with throw an Access Denied exception.)

"of" should be inserted

With the latter, the API provides for obtaining a list OF folder contents, ...

apostrophe should be inserted

If you need to store additional values within sessionState before IT`S written, do that in your handler for WinJS.Application.oncheckpoint.

insert "and" ?

So long as their combined size is less than Windows.Storage.- ApplicationData.current.roamingStorageQuota, Windows will copy that data to other devices where the same user is logged in AND has the same app installed; in fact, when an app is installed, Windows attempts to copy roaming data so that it?s there when the app is first launched.

added "s"

This is done through the settings pane object returned from Windows.UI.ApplicationSettings.SettingPane.getForCurrentView, whose show method displayS the UI (or throws a kindly exception if the app is in snapped view or doesn?t have the focus, so don?t invoke it under those conditions!).

added "a"

For example, if you encounter an error condition in the app that could be rectified by changing an app setting, you can provide a button in
the message dialog of A notification flyout that calls showSettings to open that particular pane.

Note from the Author or Editor:
The "of" should actually be "or" in this case, "you can provide a button in a message dialog or notification flyout."

"can" should be deleted

For example, the Windows 8 Camera app is a file picker provider that lets you can activate your camera, take a picture, and have it
returned as if you loaded it from the file system.

added "and"

Now that we?ve seen AND understood the capabilities of the file picker, we can turn our attention to the other libraries.

Note from the Author or Editor:
Can insert "and" or just omit "seen"

"tile" instead of "file"

This way you don?t need to associate your app with specific tile types, which also says that your app is available to service such files at any time.

"tests" should be "test"

A similar method, StorageFolder.areQueryOptionsSupported, also exists to tests support for custom queries beyond the common ones.

"though" should be "through"

Similarly, designing for touch means thinking though how gestures might enrich the user experience?and also how to provide for discoverability and user feedback that has generally relied on mouse-only events like hover.

"how its positioned" should be "how it's positioned"

Sensors tell an app what?s happening to the device in its relationship to the physical world: how its positioned in space (relative to a number of reference points), how it?s moving through space, how it?s being held relative to its ?normal? orientation, and even how much light is shining on it.

"on" should be "or"

In most cases it?s probably simpler to add an appbar command on a button on your app canvas to achieve the same goal.

"it's" should be "its"

none disables direct selection, though the element as a whole can be selected if it?s parent is selectable.

"bitwise" and "the" should be swapped

The left is 0, middle is 1, and right is 2; these values can be combined with bitwise the OR operator for chord presses (multiple buttons).

2nd "in" should be deleted

In this case, an MSInertiaStart event gets fired in to indicate that the pointer effectively continues to move even though contact was released or lifted.

"manipuationStarted" should be "manipulationStarted"
"to" should be "so"

For all others it will fire a series of manipuationStarted, manipulationUpdated, manipulationInertiaStarting, and manipulationCompleted events. Note that all of these come from WinRT to be sure to call removeEventListener as needed.

"Gesture" should be "Gestures"

At the same time, now is a good opportunity to re-read ?Sidebar: Creating Completely New Gesture?? at the end of the earlier section on the touch language.

"customHanding" should be "customHandling"

Tapping the gray customHanding element on the right shows custom handling for the keyboard?s appearance.

closing parenthesis missing

Forward (navigation

"and other" should be "another"

In any case, when the Geolocator takes and other reading and finds that the device has moved beyond the movement-Threshold, it will fire a positionChanged event, where the eventArgs.position property is a new Geoposition object.

"movementThreadhold" should be "movementThreshold"

With movementThreadhold and reportInterval, really think through what your app needs based on the accuracy and/or refresh intervals of the data you?re using in relation to the location.

"maniplations" should be "manipulations"

A tap is typically handled with a click event, whereas the others require the creation of an MSGesture object, association of that object with a pointer, and handling of MSGesture* event sequences which provide for maniplations and inertial motions together.

added "is"

The PNG format IS generally preferred over other formats, especially for text and line art, though JPEG makes smaller files for photographs.

"gets" or "is" (rotated) should be deleted

When the styles are applied, the img element gets is rotated and transformed, the canvas gets scaled, and individual parts of the svg are styled with new colors, as shown in Figure 10-2.

Note from the Author or Editor:
remove "gets"

last word should be "performance"

Again, this is processor-intensive as it?s not generally a GPU-accelerated process and might perform poorly on lower-power devices (be sure, however, to run a Release build outside the debugger when evaluating erformance).

added "in"

When you do this, Windows will automatically detect this full-screen video state and do some performance optimizations, but not if any other element is IN front of the video.

msIsStereo3D row:
"it" should be "is"

Whether the system it itself capable can be determined through ...

msAudioDeviceType row:
"specifies" seems more logical

Specified the output devices that audio will be sent to; see ?Audio Element Extension APIs.?

"Encovers" should be "Encoders"

This is important when you need to provide a custom codec for your app through Windows.Media.MediaExtensionManager, outlined in the ?Custom Decoders/Encovers and Scheme Handlers? section later in this chapter, as the codec identifies the extension to load for decoding.

"takes" should be "take"

Similarly, users will expect that an audio stream of a foreground app will takes precedence over a stream of the same category of audio playing ...

"settings" should be "setting"

Setting an audio category for any given audio element is a simple matter of settings its msAudio-Category attribute.

"you'll" should be "it'll" ? seems funny like this

The start page isn?t really essential for background audio (because you?ll never be launched for this purpose), but you need to provide something to make the manifest editor happy.

inserted comman (after screen)

This is especially important because background audio continues to play not only when the user switches to another app, but also when they switch to the Start screen, switch to the desktop, or lock the device.

"you" and "want" should we swapped

But if want you a truly seamless transition, you?ll...

should be one sentence

What you receive in your completed handler is a StorageItemThumbnail object that provides thumbnail data as a stream . You can conveniently pass to our old friend URL.createObjectURL for display in an img element and whatnot.

Note from the Author or Editor:
Should be "data as a stream, which you can ..."

"butting" should be "button"

As the fields shown earlier in Figure 10-5 are editable, the sample provides an Apply butting that invokes the applyHandler function below to write them back to the file:

Note from the Author or Editor:
Egads. This one is embarrassing! :)

"Helpers.convertStartsToSystemRating" should be "Helpers.convertStarsToSystemRating"

The Helpers.convertStartsToSystemRating method (see js/default.js) converts between 1?5 stars, as used in the WinJS.UI.Rating control, to the System.Rating value that uses a 1?99 range. The documentation for System.Rating specifically indicates this mapping.

"options" should be "option"

To provide these properties, you need to create a new BitmapPropertySet and insert an entry in that set for each desired options.

"through" should be "though"

Through not shown in the sample, you can apply effects to a transcoding operation by using the transcoder?s addAudioEffect and addVideoEffect methods.

"unless note" should be "unless noted otherwise" ?

(classes are in the Windows.Media.Capture namespace unless note)

"an" should be "and"

When you tap the Start Preview button, it creates an initializes a MediaCapture object as follows:

seems like "for" should be deleted

As mentioned in this chapter?s introduction, Netflix alone consumes for a large percentage of today?s Internet bandwidth (including that of my own home).

Note from the Author or Editor:
Remove "for"

blank line should be deleted

Plus, with the SDK you don?t need to submit your app for

DRM Conformance testing.

Note from the Author or Editor:
Yep, this is an artifact of pagination work that went unnoticed.

"primarily" should be "primary"

You can even run the app from your primarily machine using the remote debugging tools of Visual Studio, allowing you to step through the code of both source and receiver apps at the same time!

first "of" should be "or"

Animates the insertion of deletion of items from a list, as used by the ListView control.

"that" should be deleted

Each offset is an object whose properties that define the offset.

"are" (the same time) should be "at"

With animations, there are three events: animationstart (which comes after any delay has passed), animationend (when the animation finished), and animationiteration (at the end of each iteration, unless animationend also fires are the same time).

"an" (timer) should be "a"

If you?re anything like me, I imagine that one of the first things you did when you started playing with JavaScript is to do some kind of animation: set up some initial conditions, create an timer with setInterval, do some calculations in the handler and update elements (or draw on a canvas), and keep looping until you?re done.

2 typos in last sentence, it should read (I think):
A raw notification must be received by a running app or by a lock screen app with a background task with the push notification trigger - otherwise the system clearly won't know what to do with it!

Note from the Author or Editor:
Good catch--little words there!

2nd bullet: "file" instead of "tile":
SecondaryTile(tileId) Initializes the SecondaryTile with a specific ID, typically used when creating an object before an update or when unpinning the file.

5th bullet: "file" instead of "tile":
This value is typically derived from the content related to the file.

"udpateAsync " should be "updateAsync"

If you modify any properties for a SecondaryTile that has already been pinned, be sure to call its udpateAsync method to propagate those changes.

"keep" should be "keeping"

If you?ve been keep score throughout this section, you might have noticed that I?ve yet to mention Scenario 6 of the sample.

"be you" should be "you be"

The exact tile schema, should be you interested, can be found on the Tile schema reference page.

2nd "in" should be "is"

(Looking for tiny errors in strings in not my favorite pastime!)

"the" should be deleted

In such cases it would be better to have the tile cycle through a series of tiles, thereby keeping the tile active with THE more than just the last update.

"tile" should be deleted

There?s a very basic service that delivers badge updates. You can use this in Scenario 5 of the Push and periodic notifications client-side sample?enter your page?s URI in the box, press the button to start polling, and then check the sample?s tile on the Start screen TILE.

"to" should be deleted

If you use the Start screen?s app bar command to make the tile smaller, thereby using the square tile payload in the XML, you should see it switch between TO another gratuitous picture of my kid and peek text:

Note from the Author or Editor:
Omit "between" instead

"provide" should be "provides"

The Windows Azure site also provide direct support and SDKs for .NET, node.js, PHP, Java, and Python, along with Visual Studio Express 2012 with Web for Windows Azure SDK?all available again

"a" should be removed

The particular sound is set with the src attribute and must be A one of the following string values as described in the Toast audio options catalog:

"a" should be deleted, or "URIs" should be "URI"

In this case you?ll be managing a separate channel URIs for each tile.

Note from the Author or Editor:
Omit "a"

"to" should be deleted

Before a service can send updates, it must to authenticate itself with WNS by sending the Package Security Identifier (SID) and client secret as obtained through the Windows Store Dashboard.

"to" should be "a"

A 404 or 410 error is different, by the way, from an inability to deliver to notification because the client is offline.

"complete" should be "compete"

This means it isn?t having to complete with background apps that would, if allowed, take up as many resources as they possibly can.

"services" should be "service"

It?s likely that you?ve experienced situations like this directly, where you?ve started an app but it takes for-EV-er to start up because some other dark and mysterious services is chewing on the hard drive,

"an" should be deleted

Given the quotas on CPU time, writing a background task in a language like C++ or C# will allow you to do some tasks more efficiently, in which case you?ll use the Entry Point field (if the task is in a DLL in the package) and perhaps the Executable field (if the task is AN another EXE in the package) to identify the code module and specific function to call.

Note from the Author or Editor:
Actually the AN should be "in"

"reliving" should be "relieving":
It offers built-in cost awareness and resiliency to changes in connectivity, reliving apps from needing to worry about such concerns themselves.

Note from the Author or Editor:
Confirmed. Thank you.

2nd "BackgroundDownloader" should be "BackgroundUploader"

Within the BackgroundDownloader and BackgroundDownloader you have the ability to set values for individual HTTP headers by using their setRequestHeader methods.

I think business is not a verb

Put another way, whatever small fee you pay to upload apps to the Store has made it possible for you to DO business in those markets with little or no effort!

"at" should be deleted

In this section, we?ll explore at these different models and better understand how they relate to one another.

Note from the Author or Editor:
"at" should be "all"

"primarily" should be "primary" in

One of the primarily motivations behind the Store (and the associated packaging technology) is to eliminate nearly all of the past risk of software acquisition: unknown or untrusted sources, potential malware, inconsistent install/uninstall procedures, and so forth.

"they're" should be "they've"

In-app purchases cannot also be interdependent?that is, users cannot be required to purchase other options to use one they?re already bought.

"kicked" should be "kick"

And if you?re found to be truly abusive, Microsoft does reserve the right to kicked your app out of the Store altogether, if it even passes certification at the outset.

"transation" should be "transactions"

...(a BCP-47 string indicating the user?s market that is used for transation)...

"trailModeRefreshScenario" should be "trialModeRefreshScenario"

You can also try setting ExpirationDate about a minute in the future, set a breakpoint on the trailModeRefreshScenario function inside js/trial-mode.js, then run the sample again.

seems like "dates" should be "date", because "the purchase" is singular

In all cases, the receipt is an XML string that contains information such as the app or product id, the dates when the purchase was made and when the receipt was issued, and a digital signature.

Note from the Author or Editor:
It's plural because it refers to two dates, (a) purchase and (b) receipt issue. Could work either way. Perhaps better saying "the dates for both when the purchase was made and when the receipt was issued."

"mutliline" should be "multiline"

The aria-multiline attribute indicates that the chat window is a mutliline textbox such that the Enter key is taken as text input rather than as a button press that would submit a form (as with the single-line textbox).

"of" should be deleted, or maybe it should be "a line of text"

When you enter a line of in the single line control, on the other hand, Narrator only reads the new element that?s been added.

"HTML essential controls sample" mentioned twice

To see what happens, run a few of the controls samples, such as the HTML essential controls sample and HTML essential controls sample and the HTML Rating ...

parenthesis should be deleted, there's no opening one

This has two properties: highContrast, a Boolean indicating if high contrast is on), and highContrastTheme, a string with the name of the high contrast color scheme.

"names" should be "named"

To see this, make a copy of button.contrast-high.svg and name it button.contrast-white.svg, and then make a second copy names button.contrast-black.svg.

"work" should be "works"

In the manifest, naming images with resource qualifiers work for both scale and contrast, as well as language as we?ll see later.

"these" should be deleted

In Windows.Globalization.NumberFormatting we have CurrencyFormatter, DecimalFormatter, PercentFormatter, and PermilleFormatter, which you should always use these when converting data values into UI display strings.

"ahd" should probably be "and"

All of these classes are demonstrated in the Number formatting and parsing sample, where the basic process is to instantiate the formatter with or without specific codes or languages, set any necessary properties for the formatter (such as the number of digits and using separators), ahd then call its format method to obtain a string or, alternately, one of its parse* methods to turn a string into a number.

added "to"

Thanks to Unicode and the ability of HTML TO directly handle text in different languages, there?s little you need to do to make such text appear properly within your layout.

stray angle bracket

So by using HTML, CSS< and WinJS?including built-in controls?much of the mirroring is taken care of automatically; Here My Am!, for instance, just works in Hebrew.

Note from the Author or Editor:
Didn't quite get the Shift key down here, apparently :)

"by" should be replaced by "but"

If, however, you have images that really need to be replaced (as when some parts would be mirrored by other parts would not), you can use layoutdir-RTL in the image filename in the same way we?ve seen for pixel densities and contrast.

"languages" should probably be added

The resource loader supports sparse localization for dealing with slight variations between similar.

Note from the Author or Editor:
Yes, add "languages"

"of" should be deleted

Any entry of that begins with an underscore, such as the conventional <_identifier.comment> : <value> is ignored by the resource loader.

"without string the app" ? don't know if this is a typo or I just don't know the meaning. Google couldn't help either.

Doing an occasional build (without string the app) is a good practice when working with resources so that you can clean up any problems in your files, such as duplicate entries or syntax errors.

Note from the Author or Editor:
The word "string" should be "starting"

"to" should be "do"

Now for the fun part: how to we reference the string resources in markup?

inserted "pages"

In all of this, one of the more challenging pieces of markup to work with were the HTML pages for settings flyouts, namely the about.html, help.html, and privacy.html PAGES in the project?s HTML folder.

Note from the Author or Editor:
Alternately, can omit "the" before about.html

second "Control" should be deleted

Go to Control Panel > Control Clock, Language, and Region > Language and make sure the target language is added and is placed at the top of the list.

"Psuedo" should be "Pseudo"

It helps you validate that your app can handle a variety of languages, because the fictitious Psuedo Language contains some of the most problematic characteristics of localized text.

"app page" should be "app package" ?

And just in case you?re interested, the maximum size of an app page for upload is 2GB (see Building the app package).

"one" should be "once"

All such data will surely feed back into your planning and development processes, ultimately bringing you to the point of one again uploading your app with new promotional materials and more features.

"support" should be "supports"

The more you can deliver an app that understands and support this (and obviously roaming data is important here!), the more I think the app will stand out from others that, sure, run in the new environment of Windows, but otherwise offer the same experience as we?ve had for many years.
