So I have a soundHandler class that's supposed to play sounds and then point back to a function on the timeline when the sound has completed playing. But somehow, only one of the sounds plays when I try it out. EDIT: After that sound plays, nothing happens, even though I have EventHandlers set up that are supposed to do something.
Here's the code:
import mx.events.EventDispatcher;
class soundHandler {
private var dispatchEvent:Function;
public var addEventListener:Function;
public var removeEventListener:Function;
var soundToPlay;
var soundpath:String;
var soundtype:String;
var prefix:String;
var mcname:String;
public function soundHandler(soundpath:String, prefix:String, soundtype:String, mcname:String) {
EventDispatcher.initialize(this);
_root.createEmptyMovieClip(mcname, 1);
this.soundpath = soundpath;
this.soundtype = soundtype;
this.prefix = prefix;
this.mcname = mcname;
}
function playSound(file, callbackfunc) {
_root.soundToPlay = new Sound(_root.mcname);
_global.soundCallbackfunc = callbackfunc;
_root.soundToPlay.onLoad = function(success:Boolean) {
if (success) {
_root.soundToPlay.start();
}
};
_root.soundToPlay.onSoundComplete = function():Void {
trace("Sound Complete: "+this.soundtype+this.prefix+this.file+".mp3");
trace(arguments.caller);
dispatchEvent({type:_global.soundCallbackfunc});
trace(this.toString());
trace(this.callbackfunction);
};
_root.soundToPlay.loadSound("../sound/"+soundpath+"/"+soundtype+prefix+file+".mp3", true);
_root.soundToPlay.stop();
}
}
Here's the code from the .fla file:
var playSounds:soundHandler = new soundHandler("signup", "su", "s", "mcs1");
var file = "000";
playSounds.addEventListener("sixtyseconds", this);
playSounds.addEventListener("transition", this);
function sixtyseconds() {
trace("I am being called! Sixtyseconds");
var phase = 1;
var file = random(6);
if (file == 0) {
file = 1;
}
if (file<10) {
file = "0"+file;
}
file = phase+file;
playSounds.playSound(file, "transition");
}
function transition() {
trace("this works");
}
playSounds.playSound(file, "sixtyseconds");
I'm at a total loss for this one. Have been wasting hours to figure it out already.
Any help will be deeply appreciated.
Well, after using the Delegate class, I got it to work with this code:
import mx.events.EventDispatcher;
import mx.utils.Delegate;
class soundHandler{
public var addEventListener:Function;
public var removeEventListener:Function;
private var dispatchEvent:Function;
private var soundToPlay;
private var soundpath:String;
private var soundtype:String;
private var prefix:String;
private var mcname:String;
public function soundHandler(soundpath:String, prefix:String, soundtype:String, mcname:String) {
EventDispatcher.initialize(this);
_root.createEmptyMovieClip(mcname, 1);
this.soundpath = soundpath;
this.soundtype = soundtype;
this.prefix = prefix;
this.mcname = mcname;
}
private function playSoundCallback(file, callbackfunc) {
var soundname = "s"+file;
_root[soundname] = new Sound(_parent.mcname);
_root[soundname].onLoad = function(success:Boolean) {
if (success) {
_root[soundname].start();
}
};
trace("Play Sound: "+file+".mp3; Function To Call: "+callbackfunc);
_root[soundname].onSoundComplete = Delegate.create(this,function():Void {
trace("Sound Complete: "+this.soundtype+this.prefix+this.file+".mp3");
dispatchEvent({type:callbackfunc});
});
_root[soundname].loadSound("../sound/"+soundpath+"/"+soundtype+prefix+file+".mp3", true);
_root[soundname].stop();
}
private function playRandomSoundCallback(phase, scope, callbackfunc) {
var file = random(scope);
if (file == 0) {
file = 1;
}
if (file<10) {
file = "0"+file;
}
file = phase+file;
playSoundCallback(file, callbackfunc);
}
private function playSound(file) {
var soundname = "s"+file;
_root[soundname] = new Sound(_root.mcname);
_root[soundname].onLoad = function(success:Boolean) {
if (success) {
_root[soundname].start();
}
};
trace("Play Sound: "+file+".mp3");
_root[soundname].loadSound("../sound/"+soundpath+"/"+soundtype+prefix+file+".mp3", true);
_root[soundname].stop();
}
private function playSoundRandom(phase, scope) {
var file = random(scope);
if (file == 0) {
file = 1;
}
if (file<10) {
file = "0"+file;
}
file = phase+file;
playSound(file);
}
private function playSoundAS(identifier) {
var soundname = identifier;
_root[soundname] = new Sound(_root.mcname);;
trace("Play Sound AS: "+identifier+".mp3");
_root[soundname].attachSound("identifier");
_root[soundname].start();
}

I'm trying to aplicate Flyweight method pattern in a simple .net core Api to see how much memory is saved compared to not using the pattern.
I have two methods, the first one creates 5000 objects without uses the pattern and the another creates 5000 object using the pattern. After each of them create the objects, then they call a method that returns the current memory used by the App.
public class MemoryService : IMemoryService
{
private readonly TreeFactory _treeFactory;
public MemoryService()
{
_treeFactory = new TreeFactory();
}
//create without pattern
public long SetObjectsMemory()
{
List<Tree> trees = new List<Tree>();
for (int i = 0; i < 5000; i++)
{
var tree = new Tree()
{
Id = new Random().Next(1, 9999999),
Part = new PartTree()
{
Name = "Nameany",
Bark = "Barkany",
Color = "Colorany"
}
};
trees.Add(tree);
};
return Utilities.GetCurrentMemoryUsed();
}
//crete with flyweight pattern
public long SetObjectsMemoryFactory()
{
List<Tree> trees = new List<Tree>();
for (int i = 0; i < 5000; i++)
{
var tree = new Tree()
{
Id = new Random().Next(1, 9999999),
Part = _treeFactory.GetPartTree("Nameany", "Barkany", "Colorany")
};
trees.Add(tree);
}
return Utilities.GetCurrentMemoryUsed();
}
}
I use the pattern like a class that uses a list of Parts and return a part object if exists.
public class TreeFactory
{
private static List<PartTree> _parts;
public TreeFactory() {
_parts = new List<PartTree>();
}
public PartTree GetPartTree(string name, string bark, string color)
{
if (_parts.Any(x => x.Name == name && x.Bark == bark && x.Color == color))
{
return _parts.Where(x => x.Name == name && x.Bark == bark && x.Color == color).FirstOrDefault();
}
else {
var newpart = new PartTree()
{
Name = name,
Bark = bark,
Color = color
};
_parts.Add(newpart);
return newpart;
}
}
}
The way to get the current memory used by the App is using Process of this way (in Utilities class):
public static long GetCurrentMemoryUsed() {
Int64 memory;
using (Process proc = Process.GetCurrentProcess())
{
memory = proc.PrivateMemorySize64 / (1024 * 1024);
}
return memory;
}
And in my Startup i inject the MemoryService like a Singleton. In the controller i use 3 methods for call the functions:
[HttpGet, Route(nameof(WeatherForecastController.GenerateMemory))]
public IActionResult GenerateMemory()
{
var total=_memoryService.SetObjectsMemory();
return Ok(total);
}
[HttpGet, Route(nameof(WeatherForecastController.GenerateLiftMemory))]
public IActionResult GenerateLiftMemory()
{
var total = _memoryService.SetObjectsMemoryFactory();
return Ok(total);
}
[HttpGet, Route(nameof(WeatherForecastController.GetMemory))]
public IActionResult GetMemory()
{
var total = Utilities.GetCurrentMemoryUsed();
return Ok(total);
}
The problem is: When i call in the navigator the method in controller without pattern (/weatherforecast/GenerateMemory), then this returns (current)+2mb, but when i call the method
with pattern (/weatherforecast/GenerateLiftMemory) this returns (current)+3mb.
Why the method with pattern flyweight returns more used MB (growing) than the methods without the pattern ??
The repository with the code for test it. Gitlab repository memory api
The code which uses TreeFactory consumes more memory because its GetPartTree method called many times in a loop so as Linq methods Any and Where inside it. Both of these methods create additional Iterator objects under the hood in order to iterate through the collection and it causes additional memory consumption.
I wrote simple benchmark using BenchmarkDotNet with more options to demonstrate the issue

Basically, what is happening is when trying to change a variable of a Managed class (UWP), it crashes. Additionally, it seems to only crash if I try modifying a variable which is created with the app namespace. In other words, if I create a new namspace and managed class, I can modify variables just fine.
void ASynTaskCategories(void)
{
concurrency::task_completion_event<Platform::String^> taskDone;
MainPage^ rootPage = this;
UberSnip::HELPER::ASYNC_RESPONSE^ responseItem = ref new UberSnip::HELPER::ASYNC_RESPONSE();
create_task([taskDone, responseItem, rootPage]() -> Platform::String^
{
//UBERSNIP API 0.4
UberSnip::UBERSNIP_CLIENT* UberSnipAPI = new UberSnip::UBERSNIP_CLIENT();
UberSnipAPI->Http->RequestURL = "http://api.ubersnip.com/categories.php";
UberSnipAPI->Http->request();
taskDone.set(UberSnipAPI->Client->BodyResponse);
responseItem->Body = UberSnipAPI->Client->BodyResponse;
return "(done)";
}).then([taskDone, responseItem, rootPage](Platform::String^ BodyResponse) {
Platform::String^ BR = responseItem->Body;
cJSON* cats = cJSON_Parse(_string(BR));
cats = cats->child;
int *cat_count = new int(cJSON_GetArraySize(cats));
rootPage->Categories->Clear();
GENERIC_ITEM^ all_item = ref new GENERIC_ITEM();
all_item->Title = "All";
rootPage->Categories->Append(all_item);
for (int i = 0; i < *cat_count; i++) {
cJSON* cat = new cJSON();
cat = cJSON_GetArrayItem(cats, i);
string *track_title = new string(cJSON_GetObjectItem(cat, "name")->valuestring);
GENERIC_ITEM gitem;
gitem.Title = "Hi";
GENERIC_ITEM^ ubersnipCategory = ref new GENERIC_ITEM();
ubersnipCategory->Title = _String(*track_title);
rootPage->Categories->Append(ubersnipCategory);
}
});
This does not crash
UberSnipAPI->Http->RequestURL = "http://api.ubersnip.com/categories.php";
but this one does
all_item->Title = "All";
I am almost positive it has something to do with it being in the apps default namespace and it being accessed outside of the main thread ... At least that's what it seems like as that's really the only difference besides the actual class.
This is what GENERIC_ITEM looks like.
[Windows::UI::Xaml::Data::Bindable]
public ref class GENERIC_ITEM sealed {
private:
Platform::String^ _title = "";
Platform::String^ _description;
Windows::UI::Xaml::Media::ImageSource^ _Image;
event PropertyChangedEventHandler^ _PropertyChanged;
void OnPropertyChanged(Platform::String^ propertyName)
{
PropertyChangedEventArgs^ pcea = ref new PropertyChangedEventArgs(propertyName);
_PropertyChanged(this, pcea);
}
public:
GENERIC_ITEM() {
};
property Platform::String^ Title {
Platform::String^ get() {
return this->_title;
}
void set(Platform::String^ val) {
this->_title = val;
OnPropertyChanged("Title");
}
}
property Platform::String^ Description {
Platform::String^ get() {
return this->_description;
}
void set(Platform::String^ val) {
this->_description = val;
OnPropertyChanged("Description");
}
}
void SetImage(Platform::String^ path)
{
Windows::Foundation::Uri^ uri = ref new Windows::Foundation::Uri(path);
_Image = ref new Windows::UI::Xaml::Media::Imaging::BitmapImage(uri);
}
};
I know there is no issue with the class because it works perfectly fine if I run this exact same code on the initial thread.
Any suggestions? Thanks! :D
Figured it out after several hours! In case someone else is having this issue, all you must do is use the Dispatcher to run code on the UI that is not available outside of the UI thread.

I am making a web application in asp.net with MVC 4 and i'm trying to show the user twitter home feed. To get the user home feed i'm using twitterizer2. Everything work fine and i have the user home feed and the feed photo link but it doesn't display in the browser. If i open the picture link from the browser address bar it is displayed and also if i use another photo link not related with twitter everything works fine. So i'm guessing it has something to do with twitter.
My view is this:
<div class="NoBullets" style="font-size:#Model.TextSize">
<ul style="list-style-type:none">
#foreach (var status in Model.TStatusCollection)
{
<li>
<img src=#status.User.ProfileImageLocation style="float:left" width="48" height="48" align="bottom"> #status.Text<br />
#string.Format("{0:dd MMMM yyyy} {0:H:mm}", status.CreatedDate)
</li>

I have two air applications and installed them in desktop and executed them and two air processes are listed in taskbar manager.Now how can I execute some method of one air application from another air application?
Use LocalConnection.
You can Host a Connection in one AIR application and connect from the the other AIR guy... From there - you can call methods.
BEWARE: LocalConnection can be a little tricky and odd (for example, connections are global and the names can't overlap).
From the Example Doc listed above....
// Code in LocalConnectionSenderExample.as
package {
import flash.display.Sprite;
import flash.events.MouseEvent;
