  • What is Adobe Flex? Is it just Flash II?

    - by Adam Davis
    Question Alright, I'm confused by all the buzzwords and press release bingo going on. What is the relationship between flash and flex: Replace flash (not really compatible) Enhance flash The next version of flash but still basically compatible Separate technology altogether ??? If I'm starting out in Flash now, should I just skip to Flex? Follow up Ok, so what I'm hearing is that there's three different parts to the puzzle: Flash The graphical editor used to make "Flash Movies", ie it's an IDE that focuses on the visual aspect of "Flash" (Officially Flash CS3?) The official name for the display plugins (ie, "Download Flash Now!") A general reference to the entire technology stack In terms of the editor, it's a linear timeline based editor, best used for animations with complex interactivity. Actionscript The "Flash" programming language Flex An Adobe Flash IDE that focuses on the coding/programming aspect of "Flash" (Flex Builder?) A Flash library that enhances Flash and makes it easier to program for (Flex SDK?) Is not bound to a timeline (as the Flash IDE is) and so "standard" applications are more easily accomplished. Is this correct?

  • Is it possible to transcode audio in C# using DirectSound?

    - by Robert Davis
    I want to transcode a lot of audio from its source format to PCM without resampling or messing with the sample size. I figure if Windows Media Player can play the file and it doesn't use a legacy ACM codecs it must be using DirectSound to do so (this is on Windows XP and Windows Server 2k3). So is it possible to access DirectSound from C# and do so? I've tried searching the web but all the examples have been about playback which I have no interest in doing.

  • AOL Contact API and AIM Buddy API

    - by Joe Davis
    I've searched the AOL Developer network and found a Contacts API page that says "coming soon" and is dated last year. I've checked the SDK and APIs and found some AIM Buddy references... I'm looking for documentation on retrieving contact email addresses on behalf of users based on their AOL email login. Am I missing something or is the documentation really difficult to find? Does someone have a useful link?

  • Best Practice - Removing item from generic collection in C#

    - by Matt Davis
    I'm using C# in Visual Studio 2008 with .NET 3.5. I have a generic dictionary that maps types of events to a generic list of subscribers. A subscriber can be subscribed to more than one event. private static Dictionary<EventType, List<ISubscriber>> _subscriptions; To remove a subscriber from the subscription list, I can use either of these two options. Option 1: ISubscriber subscriber; // defined elsewhere foreach (EventType event in _subscriptions.Keys) { if (_subscriptions[event].Contains(subscriber)) { _subscriptions[event].Remove(subscriber); } } Option 2: ISubscriber subscriber; // defined elsewhere foreach (EventType event in _subscriptions.Keys) { _subscriptions[event].Remove(subscriber); } I have two questions. First, notice that Option 1 checks for existence before removing the item, while Option 2 uses a brute force removal since Remove() does not throw an exception. Of these two, which is the preferred, "best-practice" way to do this? Second, is there another, "cleaner," more elegant way to do this, perhaps with a lambda expression or using a LINQ extension? I'm still getting acclimated to these two features. Thanks. EDIT Just to clarify, I realize that the choice between Options 1 and 2 is a choice of speed (Option 2) versus maintainability (Option 1). In this particular case, I'm not necessarily trying to optimize the code, although that is certainly a worthy consideration. What I'm trying to understand is if there is a generally well-established practice for doing this. If not, which option would you use in your own code?

  • Delphi 6 OleServer.pas Invoke memory leak

    - by Mike Davis
    There's a bug in delphi 6 which you can find some reference online for when you import a tlb the order of the parameters in an event invocation is reversed. It is reversed once in the imported header and once in TServerEventDIspatch.Invoke. you can find more information about it here: http://cc.embarcadero.com/Item/16496 somewhat related to this issue there appears to be a memory leak in TServerEventDispatch.Invoke with a parameter of a Variant of type Var_Array (maybe others, but this is the more obvious one i could see). The invoke code copies the args into a VarArray to be passed to the event handler and then copies the VarArray back to the args after the call, relevant code pasted below: // Set our array to appropriate length SetLength(VarArray, ParamCount); // Copy over data for I := Low(VarArray) to High(VarArray) do VarArray[I] := OleVariant(TDispParams(Params).rgvarg^[I]); // Invoke Server proxy class if FServer <> nil then FServer.InvokeEvent(DispID, VarArray); // Copy data back for I := Low(VarArray) to High(VarArray) do OleVariant(TDispParams(Params).rgvarg^[I]) := VarArray[I]; // Clean array SetLength(VarArray, 0); There are some obvious work-arounds in my case: if i skip the copying back in case of a VarArray parameter it fixes the leak. to not change the functionality i thought i should copy the data in the array instead of the variant back to the params but that can get complicated since it can hold other variants and seems to me that would need to be done recursively. Since a change in OleServer will have a ripple effect i want to make sure my change here is strictly correct. can anyone shed some light on exactly why memory is being leaked here? I can't seem to look up the callstack any lower than TServerEventDIspatch.Invoke (why is that?) I imagine that in the process of copying the Variant holding the VarArray back to the param list it added a reference to the array thus not allowing it to be release as normal but that's just a rough guess and i can't track down the code to back it up. Maybe someone with a better understanding of all this could shed some light?

  • Is a signal sent with kill to a parent thread guaranteed to be processed before the next statement?

    - by Jonathan M Davis
    Okay, so if I'm running in a child thread on linux (using pthreads if that matters), and I run the following command kill(getpid(), someSignal); it will send the given signal to the parent of the current thread. My question: Is it guaranteed that the parent will then immediately get the CPU and process the signal (killing the app if it's a SIGKILL or doing whatever else if it's some other signal) before the statement following kill() is run? Or is it possible - even probable - that whatever command follows kill() will run before the signal is processed by the parent thread?

  • Streaming audio - where to start?

    - by Adam Davis
    I need to develop an embedded audio streaming server. Requirements: Voice quality or better Intended for low power wifi transmission Broad support in existing software and devices (ie, windows media player, quicktime, vlc, iPhone, Android, etc). Royalty/patent free, or cheap to license Preferences: Low overhead TCP/IP based streaming protocol Voice grade codec (easy to implement in software, no DSP, 32bit CPU if needed) Would be nice if it supported HTML5 browsers, but is there any codec (such as raw) that is supported by the latest browsers that is lower overhead than MP3? Therefore: What are the relevant streaming protocols I should be looking at? What are the relevant codecs I should be looking at? What transport streams should I be looking at? What am I missing, or where else should I be looking for this type of need?

  • navigateToURL with GET parameters in local SWF

    - by Michael Brewer-Davis
    I'm running a Flex application locally (local-with-filesystem or local-trusted), and I'm trying to call navigateToURL to a local page using GET parameters. Flash Player seems to be ignoring the parameters when opening the local page, though. I've been scouring the Flash security pages to find a documented prohibition for this, but haven't found anything. Pointers? How would you work around this issue? My Flex app: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ private function onClick(event:MouseEvent):void { var request:URLRequest = new URLRequest("target.html"); request.data = new URLVariables(); request.data.text = "stackoverflow.com"; navigateToURL(request); } ]]> </mx:Script> <mx:Button label="Go" click="onClick(event)" /> </mx:Application> And my target.html: <html> <head> <script language="JavaScript"> <!-- function showURL() { alert(window.location.href); } //--> </script> </head> <body onload="showURL()" /> </html>

  • AppDomain.UnhandeledException event not fired

    - by Yaakov Davis
    In a WPF application, the app simply crashes, without the above event being fired. (I'm also registered to DispatcherUnhandeledException, which doesn't fire as well.) I conclude that it doesn't fire since the handler is defined to place a log entry. When looking at the log, there's no corresponding entry. It happens in a production environment; I'm unable to point at a particular scenario. I've read few descriptions on scenarios where this might happen, but I still don't have a clear grasp on this. Can anyone share his experience / knowledge on this? How can I find the root of the crash and solve it? Many thanks.

  • All possible permutations of a set of lists in Python

    - by Ian Davis
    In Python I have a list of n lists, each with a variable number of elements. How can I create a single list containing all the possible permutations: For example [ [ a, b, c], [d], [e, f] ] I want [ [a, d, e] , [a, d, f], [b, d, e], [b, d, f], [c, d, e], [c, d, f] ] Note I don't know n in advance. I thought itertools.product would be the right approach but it requires me to know the number of arguments in advance

  • How to convert different local float format to standard float format, using zend?

    - by Linto davis
    my local is 'en_IN' (ie Zend_Registry::get('Zend_Locale')) I have to convert the local value to standard float number format for example 1,235.23 = 1235.23 3.23 = 3.23 I have used the following code Zend_Locale_Format::getFloat($value, array('locale' = Zend_Registry::get('Zend_Locale'))); it working fine for 1,235.23, and i get the answer 1235.23. But when i give 3.23 , i get the error on this code And the error shown as 'No localized value in 3.23 found', This issue is happening in the browser opera, when we set the language is English(IN)(en-IN)

  • Orbital equations, and power required to run them

    - by Adam Davis
    Due to a discussion on the SO IRC today, I'm curious about orbital mechanics, and The equations needed to solve orbital problems The computing power required to solve complex problems The question in particular is calculating when the Earth will plow into the Sun (or vice versa, depending on the frame of reference). I suspect that all the gravitational pulls within our solar system may need to be calculated, which makes me wonder what type of computer cluster is required, or can this be done on a single box? I don't have the experience to do a back of the napkin test here, but perhaps you do? Also, much thx to Gortok for the original inspiration (see comments).

  • In XAML is there way to bind key press and key release to specific commands?

    - by Ashley Davis
    In my application I have keys that bound to commands using the KeyBinding class. The command is executed when the key is pressed and released. I have a special case where I want to bind separate commands to the pressed action and to the released action. For example when the space key is pressed I want my app to run a command to enter a special mode. Then when the space key is released I want to run another command to exit that special mode. Currently I do this by manually handling the KeyUp and KeyDown events. Is there anyway to execute commands for pressed and released purely in XAML?

  • Recursion in assembly?

    - by Davis
    I'm trying to get a better grasp of assembly, and I am a little confused about how to recursively call functions when I have to deal with registers, popping/pushing, etc. I am embedding x86 assembly in C++. Here I am trying to make a method which given an array of integers will build a linked list containing these integers in the order they appear in the array. I am doing this by calling a recursive function: insertElem (struct elem *head, struct elem *newElem, int data) -head: head of the list -data: the number that will be inserted at the end of a list -newElem: points to the location in memory where I will store the new element (data field) My problem is that I keep overwriting the registers instead of a typical linked list. For example, if I give it an array {2,3,1,8,3,9} my linked-list will return the first element (head) and only the last element, because the elements keep overwriting each other after head is no longer null. So here my linked list looks something like: 2--9 instead of 2--3--1--8--3--9 I feel like I don't have a grasp on how to organize and handle the registers. newElem is in EBX and just keeps getting rewritten. Thanks in advance!

  • Enumerating computers in NT4 domain using WNetEnumResourceW (C++) or DirectoryEntry (C#)

    - by Kevin Davis
    I'm trying to enumerate computers in NT4 domains (not Active Directory) and support Unicode NetBIOS names. According to MSDN, WNetEnumResourceW is the Unicode counterpart of WNetEnumResource which to me would imply that using this would do the trick. However, I have not been able to get Unicode NetBIOS names properly using WNetEnumResourceW. I've also tried the C# rough equivalent DirectoryEntry using the WinNT: provider with no luck on Unicode names either. If I use DirectoryEntry on Active Directory (using the LDAP: provider) I do get Unicode names back. I noticed that during some debugging my code using DirectoryEntry and the WinNT: provider, the exceptions I saw were of type System.Runtime.InteropServices.COMException which tends to make me believe that this is just calling WNetEnumResourceW via COM. This web page implies that for some Net APIs the MS documentation is incomplete and possibly inaccurate which further confuses things. Additionally I've found that using the C# method which certainly results in cleaner, more understandable code also yields incomplete results in enumerating computers in domains\workgroups. Does anyone have any insight on this? Is it possible that computer acting as the WINS server is mangling the name? How would I determine this? Thanks

  • How do I simulate a scrollbar click with jQuery?

    - by Ian Davis
    How do I simulate a scrollbar click with jQuery? So, if a user clicks on a div that says "scroll down," it'll be the exact same behavior as if he/she clicked on the down arrow of the browser's scrollbar. Using the current browser's behavior would be optimal, vs. doing something like $.browser.scrolldown(200,'fast'). Something like $.browser.triggerDownArrowOnScrollBar() would be sweet!

  • How do I trigger a closing animation for a WPF ContextMenu?

    - by Ashley Davis
    Does anyone know if it is possible to trigger an animation when a WPF ContextMenu closes? I have code that triggers an animation when the ContextMenu is opened. The animation makes the context menu fade into view. I also want an animation when the ContextMenu is closed that makes it fade out. The code that starts the opened fade-in animation looks something like this: var animation = new DoubleAnimation(); animation.From = 0; animation.To = 1; animation.Duration = TimeSpan.FromSeconds(0.2); animation.Freeze(); menu.BeginAnimation(ContextMenu.OpacityProperty, animation); The fade-in animation also runs on sub-menu items. Note that I also want to run other animations besides fade in and fade out. Eg I want the context menu to scale up from nothing so that it sort of 'bounces' into view.
