So I'm using the Silverlight toolkit sample to help me build a CustomMessageBox for a Windows Phone 8 app that I'm building. When a user clicks on a certain button inside the app I want to tell the user that they first need to launch something else before this button will work.
So in the message box I'll explain this to the user, but I want to add a "Don't Show me this again" checkbox. The problem is that I'm not sure how to handle the "don't show me again" checkbox in the messageBox.Dissmissed event. The toolkit sample leaves this part out and I can't seem to find information on the internet that is really clear enough for me.
Thanks in advance for any help, I'm new to coding and rely on Samples a lot to get me going.
messageBox.Dismissed += (s1, e1) =>
{
switch (e1.Result)
{
case CustomMessageBoxResult.LeftButton:
// Do ask me again.
break;
case CustomMessageBoxResult.None:
if ((bool)checkbox.IsChecked)
{
// Do not ask me again.
}
else
{
// Ask again later.
}
break;
default:
break;
}
};
messageBox.Show();
If user selects not to prompt him again, you can save his choice in isolated storage settings like this..
System.IO.IsolatedStorage.IsolatedStorageSettings settings = System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings;
if(!settings.Contains("DontAskMeAgain"))
settings.Add("DontAskMeAgain", "1");
else
settings["DontAskMeAgain"] = "1";
And before you prompt user with your CustomMessageBox, first check for setting DontAskMeAgain
if(!(settings.Contains("DontAskMeAgain") && settings["DontAskMeAgain"]=="1"))
//CustomMessageBox.show();
else
//dont show

[Question]
On Windows Phone 8.1, what exactly happens in between the time when the user leaves the app and the OnSuspended event fires? I'm having trouble with the ability to manage objects in that span, in particular MediaCpture object.
To better explain the problem, here is the scenario:
The user is on a page with a video preview being pumped to a CaptureElement
The user taps the Start button
The user taps Back button and returns to the page with a broken MediaCapture
With WinRT there isn't an ObscuredEvent and OnNavigatingFrom doesn’t fire unless you’re going to another page in the same Frame. After some investigation, I've found that the only event that fires is Window.Current.VisibilityChanged
I've gone ahead and hook it when the page is NavigatedTo and unhooked in OnNavigatedFrom (see ex2 below). Inside the event, I check for parameter that tells if the app is hiding or showing and dispose/initialize accordingly(see ex.1 below).
[Problem]
However, this only works with the debugger attached. If I do this without the debugger attached, it doesn't reinitialize and frequently crashes the camera and I have to literally reboot the device.
Code Example 1 (note: e.Visible == false is leaving the app and true when returning)
async void Current_VisibilityChanged(object sender, VisibilityChangedEventArgs e)
{
if (!e.Visible) //means leaving the app
{
await DisposeAll(); //cleans the MediaCapture and CaptureElement
}
else
{
if(mediaCaptureManager != null) await DisposeAll();
await Initialization(); //set up camera again
}
}
Example 2 (hooking into the event)
protected override void OnNavigatedTo(NavigationEventArgs e)
{
Window.Current.VisibilityChanged += Current_VisibilityChanged;
this.navigationHelper.OnNavigatedTo(e);
}
protected async override void OnNavigatedFrom(NavigationEventArgs e)
{
Window.Current.VisibilityChanged -= Current_VisibilityChanged;
this.navigationHelper.OnNavigatedFrom(e);
}
[Update: Resolution]
Instead of using VisibilityChanged, hook into Window.Current.Activated on the page's constructor. With the debugger completely detached, the Activated event will provide the WindowActivationState parameter in the WindowActivatedEventArgs. Like this:
private async void CurrentOnActivated(object sender, WindowActivatedEventArgs e)
{
if(e.WindowActivationState == CoreWindowActivationState.Deactivated)
{
//dispose MediaCapture here
}
else if(e.WindowActivationState == CoreWindowActivationState.CodeActivated || e.WindowActivationState == CoreWindowActivationState.PointerActivated)
{
//initialize MediaCapture here
}
}
See my answer in https://stackoverflow.com/a/28592882/3998132. Using Window.VisibilityChanged in conjunction with your Page\UserControl Loaded\Unloaded handler should solve your issue I believe.
Using Window.Activated is less desirable than Window.VisibilityChanged because Activated relates to being visible AND having focus where as VisibilityChanged only pertains to visibility. For showing a preview having focus is not applicable. Since Windows Store apps on Windows Phone can only have one Window showing there is no difference in using either however if your app becomes universal and runs on let's say on Windows 8+ Modern shell (which can show multiple Store apps with the Snap window feature) or Windows 10 desktop (which can support multiple Store apps showing at the same time) you will not want to stop preview when a user changes focus from your app but your app is still showing.
I'm not sure if it wouldn't be more suitable to use Suspending/Resuming events. Note only that in this case, you will have to debug it properly - it behaves little different while being run with/without debugger attached.
As for the code - hooking your event in OnNavigatedTo/OnNavigatedFrom is not a good idea - when the OS suspends the app and you are using SuspensionManager then OnNavigatedFrom will be called, but when you go back to your app (resume it), then OnNavigatedTo will not be called.
Using Window events may also work here, but why not subscribe it once, somewhere in constructor? - it's window-wide and hence in phone there is only one window, which stands for app, then subscribe once. In this case, you may add a line that recognizes the current page in window and if that page contains mediacapture then dispose (create similar). Then you can also dispose/initialize in navigation events in case user doesn't leave your app and just navigate.
There's so many questions regarding Facebook's sharer.php, but they're all out of date. At first Facebook depreciated it, but according to FB's dev documentation it's now back. (Edit: And now it's going again...?)
You used to be able to use it like this:
http://www.facebook.com/sharer/sharer.php?u=<url to share>&t=<message text>
But the documentation now only mentions this:
https://www.facebook.com/sharer/sharer.php?u=<url to share>
Is it possible to set some pre-entered text into the dialogue box that appears when sharing a link on Facebook?
Thanks.
The Share dialog takes only the URL to share as parameter, nothing else (title, description, picture, …) any more. It fetches this data from the URL itself, from the Open Graph meta elements embedded into the document, or it takes a “guess” from the content if those are not present.
And even the “older” version of the Share dialog has not been taking a pre-set message parameter for a long time now – because you are not supposed to pre-fill the message in any way when sharing something, not matter what way the share actually happens. (“Not supposed to” actually meaning, Platform Policies explicitly forbid you from doing so.)
You can of course also share links via API (rather called “posting” a link then) – and because that happens in the background, the message is a parameter you specify while doing so. But the same rules apply – the message is supposed to be created by the user themselves beforehand, which effectively means they should have typed it in somewhere before. And even there it should not have been pre-filled so that they just have to press enter or click a button.
And since they announced API v2.0, all new apps will have to go through “login review” before they will be able to ask for any advanced permission (and posting a link requires one) – and with a pre-filled message in your app’s posting flow, you will definitively not get approval. Of course, you could try to “cheat” on that, and implement the pre-filling of the message only afterwards … but again, doing so is a clear violation of Platform Policies, and will get your app blocked when you are caught doing so.
And if you are planning to do this for multiple users with the same or largely similar messages, you can assume that Facebook’s algorithms will catch that quite easily.
Just one small comment - while it is not possible to edit the text as the other comments say - it is possible to edit everything going on in that page if you can install a browser extension on your client's machines (you did not specify your use case so I am mentioning this just in case you are developing something that you are able to influence in the client machine level).
For example, with a chrome extension, you can inject scripts into facebook.com domain. in the extension manifest.json:
"content_scripts": [
{
"matches": ["https://*.facebook.com/*",
And then this might be your contnet script, where you can play around with the text by hooking up to the markeup. This example sends out analytics (facebook sharer conversion rate) and changes some text (from "share" to "upload" to facebook):
sharer = (function () {
var _ref = qs('ref') ? qs('ref') : 'unknown';
function qs(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
function isSharer() {
return location.pathname === '/sharer/sharer.php';
}
function bindEvents() {
$('button[name="share"]').click(function() {
analytics.send('fb_sharer', 'share', _ref);
});
$('#u_0_0').click(function() {
analytics.send('fb_sharer', 'cancel', _ref);
});
}
function changeText() {
console.log($('.fcw').length);
$('.fcw').text('Upload to Facebook');
}
function load() {
if (!isSharer()) return;
changeText();
analytics.send('fb_sharer', 'view', _ref);
bindEvents();
}
return {
load: load
}
})();
I'm making a game in AS3 when you can save and restore your game.
The player can load his saved game at the introscreen OR during the game.
I've got an error (not very important as the game is still working but I'd like to correct in order to be clean) as I don't know how to put it in code.
So, when the player click on "load" at the Introscreen, a window opens where he can choose wich games he wants to restore.
When he choose a game, he click on it and the IntroScreen AND the restore window disappear.
Here's the code for this :
if(allSaveData){
..
dispatchEvent(new Event("closeThis"));
this.parent.removeChild(introScreen);
}
But when he's in the game and he wants to restore. He clicks on "esc" and the restore windows appears. But the IntroScreen IS NOT HERE. So when he restore his game, I've got an error with "this.parent.removeChild(introScreen);" as IntroScreen is not here.
I've tried this :
if(allSaveData){
..
dispatchEvent(new Event("closeThis"));
}
if (introScreen.visible == true){
this.parent.removeChild(introScreen);
}
But it's not working.
Do you know how I can tell the code "if introscreen is here close it, if not don't" ?
Thank you for your help !
visible is to show/hide a display object. You can't use this to determine whether the object is added in display list or not. There are a number of options to achieve this.
Option 1: Check the parent property of introScreen.
if (introScreen.parent) {
introScreen.parent.removeChild(introScreen);
}
Option 2: Use the contains method.
if (this.parent.contains(introScreen)) {
this.parent.removeChild(introScreen);
}
Option 3: Use try-catch block and simply ignore the error.
try {
this.parent.removeChild(introScreen);
} catch(err:Error) {
// ignore the error when it's not present
}
Try
introScreen.parent.removeChild(introScreen)
I am looking for any way to make the entire screen blink red, or whatever color, when there is an unread email. It could be for any email client. I have done a lot of googling and can't find anything. There is an add-on to thunderbird that creates a little blinking notification, but it only appears very small in the lower right hand corner of the screen.
I was thinking of maybe some add-on to Firefox or Chrome that would allow me to write custom css and javascript that would run on Gmail and make the blinking happen.
Any ideas are greatly appreciated.
I know this is not you regular SO question, but y'all are great and I don't know where else to turn. If there is a better forum out there for this type of question, you could also inform me of it.
Thanks!
I have found this program while searching, haven't tried it. But it says it can execute an external program when email arrives. So seems like you can write a little C# application that can perform the task you want and execute when new email arrives.

Instead of making a Chrome plugin, I would either make the window title blink or use HTML5 Notifications. Create a simple page which polls your IMAP Gmail for new messages, and include gmail in a large iFrame. If a new message is found, your outer window can issue the notification.
HTML5 Notifications: http://www.html5rocks.com/en/tutorials/notifications/quick/
Blinking Title (adopted from this):
var newMailBlinker = (function () {
var oldTitle = document.title,
msg = 'New Mail!',
timeoutId,
blink = function() {
document.title = document.title == msg ? ' ' : msg;
},
clear = function() {
clearInterval(timeoutId);
document.title = oldTitle;
window.onmousemove = null;
timeoutId = null;
};
return function () {
if (!timeoutId) {
timeoutId = setInterval(blink, 1000);
window.onmousemove = clear;
}
};
}());
PHP Poll Gmail IMAP (adopted from this):
$t1=time();//mark time in
$tt=$t1+(60*1);//total time = t1 + n seconds
do{
if(isset($t2)) unset($t2);//clean it at every loop cicle
$t2=time();//mark time
if(imap_num_msg($imap)!=0){//if there is any message (in the inbox)
$mc=imap_check($imap);//messages check
//var_dump($mc); die;//vardump it to see all the data it is possible to get with imap_check() and them customize it for yourself
echo 'New messages available';
}else echo 'No new messagens';
sleep(rand(7,13));//Give Google server a breack
if(!#imap_ping($imap)){//if the connection is not up
//start the imap connection the normal way like you did at first
}
}while($tt>$t2);//if the total time was not achivied yet, get back to the beginning of the loop
jQuery AJAX Polling to your IMAP script (adopted from this):
// make the AJAX request
function ajax_request() {
$.ajax({
url: '/path/to/gmail/imap/checkMessages.php',
dataType: 'json',
error: function(xhr_data) {
// terminate the script
},
success: function(xhr_data) {
console.log(xhr_data);
if (xhr_data.status == 'No new messages') {
setTimeout(function() { ajax_request(); }, 15000); // wait 15 seconds than call ajax request again
} else {
newMailBlinker(); // blink the title here for new messages
}
}
contentType: 'application/json'
});
}
Obviously you wouldn't use jQuery AND PHP to poll. Pick one to do the polling. I'd recommend have the client do the polling and have PHP check IMAP once per connection. That being said, these snippets should get you started :)
Grab the current google mail checker extension sample (https://developer.chrome.com/extensions/samples.html). Convert it to a packaged app (grab the pieces you want), open a very large window and close it quickly. That should do the trick. Sadly Fullscreen doesnt seem to be possible. But i dont know if thats a problem.
Assuming your dad has the client page always opened, you could just write an extension and manipulate the screen with JS.
You could for example:
Use the gmail client in chrome
Write a chrome extension that checks for new e-mails that come in. You could achieve this by identifying new e-mails. I believe gmail uses a specific css class for new e-mails. So your JS just needs to check for that class.
Have the extension change the page from white to red and back to white a few times (or till the e-mail is read).
You could also possibly have the chrome extension play a sound when a new email arrives?
I found chrome extensions a lot easier to use than FF, especially if you're just going to use JS.
I want to create an AIR application in which i need to show the notification that when AIR application is minimize then at some interval of time message shows from the system tray similar like giving information.
I have visited this LINK, its a nice component but tutorial is not that much good as component. I need to create a component like that or source is available from this site so modification in this component will also be acceptable. so please help me.
EG: When you minimize the Yahoo Messenger and some one is sign-out or sign-in then it gives notification i want component similar like that...
Thanks in Advance
First Step, We have created a Custom Popup control for Notifications display.
In the second step, we have controlled the display of that popup using the following code
if(!this.stage.nativeWindow.visible || this.stage.nativeWindow.displayState == NativeWindowDisplayState.MINIMIZED)
{
stage.nativeWindow.alwaysInFront = true;
fadeTimer = new Timer(5000,1);
fadeTimer.start();
fadeTimer.addEventListener(TimerEvent.TIMER_COMPLETE, fadePopUp);
popUpWindow = new PopUpWindow();
popUpWindow.isAlerts = true;
popUpWindow.Message = "<b>You have "+event.numNewMessages+" new notification messages<b>";
popUpWindow.type = NativeWindowType.LIGHTWEIGHT;
popUpWindow.open(true);
popUpWindow.fadeInEffect.play();
popUpWindow.nativeWindow.x = Capabilities.screenResolutionX - popUpWindow.width - 10;
popUpWindow.nativeWindow.y = Capabilities.screenResolutionY - popUpWindow.height - 35;
}
The condition used above is what we have used to find out, whether our application window is minimized to System Tray or not. Even though it is not a perfect fix, It didn't fail me yet. It's quiet stable for my app.
