  • mp3 playback stop echoing, as3

    - by pixelGreaser
    Hitting play more than once, causes an echo and I can't stop my mp3 player. What's the best practice for mp3 playback? var mySound:Sound = new Sound(); playButton.addEventListener (MouseEvent.CLICK, myPlayButtonHandler); var myChannel:SoundChannel = new SoundChannel(); function myPlayButtonHandler (e:MouseEvent):void { myChannel = mySound.play(); } stopButton.addEventListener(MouseEvent.CLICK, onClickStop); function onClickStop(e:MouseEvent):void{ myChannel.stop(); }

  • What things must I know about OpenAL memory management?

    - by mystify
    I am playing sound with OpenAL, and it seems to increase memory footprint dramatically for every little sound I play. It seems that OpenAL never frees memory itself and that playing a Source causes memory footprint to grow. I couldn't find any good resources about OpenAL memory management, but I bet I must do a lot of stuff myself. Maybe someone knows a ressource for that?

  • Adobe Flash and mp3 licence

    - by Dovyski
    When I publish a Flash file that contains any sound (such as a WAV file), I can choose the sound compression method (MP3, raw, ADPCM, etc.). My question is about the mp3 compression and it's licence. Flash gives me the option to compress a WAV file as mp3, but is the licence to use the mp3 format included? I have paid for a Flash licence, does it give the right to use mp3 in my SWF files freely or do I have to pay royalties to someone else?

  • How do I link ASP.NET membership/role users to tables in db?

    - by SnapConfig.com
    I am going to use forms authentication but I want to be able to link the asp.net users to some tables in the db for example If I have a class and students (as roles) I'll have a class students table. I'm planning to put in a Users table containing a simple int userid and ASP.NET username in there and put userid wherever I want to link the users. Does that sound good? any other options of modeling this? it does sound a bit convoluted?

  • Is it possible to capture audio output and apply effects to it?

    - by Ciaran
    Using .NET and DirectSound I want to be able to take all output sound that is coming from my audio device and apply effects to it. I've had a quick look at the docs on MSDN and there doesn't seem to be any explanation as to how to do something like this. I've read elsewhere that you'd be better off writing a driver to sit in front of your real audio driver and have that do whatever you want with the sound. Any ideas anyone to push me in the right direction?

  • Device drivers and Windows

    - by b-gen-jack-o-neill
    Hi, I am trying to complete the picture of how the PC and the OS interacts together. And I am at point, where I am little out of guess when it comes to device drivers. Please, don´t write things like its too complicated, or you don´t need to know when using high programming laguage and winapi functions. I want to know, it´s for study purposes. So, the very basic structure of how OS and PC (by PC I mean of course HW) is how I see it is that all other than direct CPU commands, which can CPU do on itself (arithmetic operation, its registers access and memory access) must pass thru OS. Mainly becouse from ring level 3 you cannot use in and out intructions which are used for acesing other HW. I know that there is MMIO,but it must be set by port comunication first. It was not like this all the time. Even I am bit young to remember MSDOS, I know you could access HW directly, becouse there ws no limitation, no ring mode. So you could to write string to diplay use wheather DOS function, or directly acess video card memory and write it by yourself. But as OS developed, there is no longer this possibility. But it is fine, since OS now handles all the HW comunication, and frankly it more convinient and much more safe (I would say the only option) in multitasking environment. So nowdays you instead of using int instructions to use BIOS mapped function or DOS function you call dll which internally than handles everything you don´t need to know about. I understand this. I also undrstand that device drivers is the piece of code that runs in ring level 0, so it can do all the HW interactions. But what I don´t understand is connection between OS and device driver. Let´s take a example - I want to make a sound card make a sound. So I call windows API to acess sound card, but what happens than? Does windows call device drivers to do so? But if it does call device driver, does it mean, that all device drivers which can be called by winAPI function, must have routines named in some specific way? I mean, when I have new sound card, must its drivers have functions named same as the old one? So Windows can actually call the same function from its perspective? But if Windows have predefined sets of functions requored by device drivers, that it cannot use new drivers that doesent existed before last version of OS came out. Please, help me understand this mess. I am really getting mad. Thanks.

  • Play an AudioBufferSourceNode twice?

    - by alltom
    Should I be able to use the same AudioBufferSourceNode to play a sound multiple times? For some reason, calling noteGrainOn a second time doesn't play audio, even with an intervening noteOff. This code only plays the sound once: var node = audioContext.createBufferSource() node.buffer = audioBuffer node.connect(audioContext.destination) var now = audioContext.currentTime node.noteGrainOn(now, 0, 2) node.noteOff(now + 2) node.noteGrainOn(now + 3, 0, 2) node.noteOff(now + 5)

  • Does GoDaddy supports RESTful services via WCF

    - by Amir Naor
    After deploying a WCF RESTful service that i created using the REST started kit, i got several errors that i managed to solve following this post: http://www.edoverip.com/edoverip/index.php/2009/01/30/running-wcf-on-godaddy Now i'm stuck with this error: IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used I saw that others got to this point without a solution. GoDaddy support dont know nothing. Is it possible at all? Are there any web hosting services that you know that support that?

  • Find next date for certain record in SQL Server 2008

    - by Karl
    Hi In SQL Server 2008: I have two tables, dtlScheme and dtlRenewal, with a one to many relationship (one scheme can have many renewals). dtlRenewal has a unique key (dteEffectiveDate, dtlSchemeID). Now suppose I have the following data in dtlRenewal: dtlRenewalID dtlSchemeID dteEffectiveDate 1 1 1/1/2005 2 1 1/1/2006 3 1 1/1/2007 4 1 1/1/2008 5 1 1/1/2009 I would like to find for each renewal the next and previous effective date for the scheme. In other words, I need to return this: dtlRenewalID dtlSchemeID dteEffectiveDate dtePrevious dteNext 1 1 1/1/2005 NULL 1/1/2006 2 1 1/1/2006 1/1/2005 1/1/2007 3 1 1/1/2007 1/1/2006 1/1/2008 4 1 1/1/2008 1/1/2007 1/1/2009 5 1 1/1/2009 1/1/2008 NULL Thanks Karl

  • How to fix "could not find a base address that matches schema http"... in WCF

    - by Craig Shearer
    I'm trying to deploy a WCF service to my server, hosted in IIS. Naturally it works on my machine :) But when I deploy it, I get the following error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Googling on this, I find that I have to put a serviceHostingEnvironment element into the web.config file: <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> But once I have done this, I get the following: Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https]. It seems it doesn't know what the base address is, but how do I specify it? Here's the relevant section of my web.config file: <system.serviceModel> <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <behaviors> <serviceBehaviors> <behavior name="WcfPortalBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IWcfPortal" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00" openTimeout="00:10:00" closeTimeout="00:10:00"> <readerQuotas maxBytesPerRead="2147483647" maxArrayLength="2147483647" maxStringContentLength="2147483647"/> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="WcfPortalBehavior" name="Csla.Server.Hosts.Silverlight.WcfPortal"> <endpoint address="" binding="basicHttpBinding" contract="Csla.Server.Hosts.Silverlight.IWcfPortal" bindingConfiguration="BasicHttpBinding_IWcfPortal"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel> Can anybody shed some light on what's going on and how to fix it? Thanks! Craig

  • SQL Server schema comparison - leaves behind obsolete files on synchronization

    - by b0x0rz
    Directly related to http://stackoverflow.com/questions/2768489/visual-studio-2010-database-project-is-there-a-visual-way/2772205#2772205 I have a problem synchronizing between database project and a database in Visual Studio. Usually I synchronize FROM database TO database project (using the Visual Studio data scheme compare new schema comparison). The synchronization works, BUT when I for example corrected the spelling of a key in the database and synchronized it - the file with the WRONG spelling of a key remains (albeit is commented out inside). the new one is correctly added. This file happens to be in: [project name]/Scheme Objects/Schemas/dbo/Tables/Keys But for sure there are others elsewhere. how to automatically remove such obsolete files when synchronizing? thnx

  • WebsiteSpark & Visual Studio 2010

    - by Amadiere
    Having a look around at WebsiteSpark from Microsoft - the deal is good (especially if you were looking to go down this path already). But I'm one of those people that likes to 'wait for the next version' if I'm in no rush to sign up. One question that's been bugging me is whether or not the program includes upgrades to Visual Studio and/or they will change the starting pack at some point? Currently, If you sign up now, you get 3 copies of Visual Studio 2008. If you're umming and ahhing about the scheme, is it worth waiting and hoping that they adapt their program so that it comes with VS2010? Or maybe that they'll offer free updates to those already in the scheme? (This question may be a little subjective I guess and it probably applies to the BizSpark side of things as well. Have there been any hints set in other Microsoft programs that might indicate the outcome? ).

  • How can I structure and recode messy categorical data in R?

    - by briandk
    I'm struggling with how to best structure categorical data that's messy, and comes from a dataset I'll need to clean. The Coding Scheme I'm analyzing data from a university science course exam. We're looking at patterns in student responses, and we developed a coding scheme to represent the kinds of things students are doing in their answers. A subset of the coding scheme is shown below. Note that within each major code (1, 2, 3) are nested non-unique sub-codes (a, b, ...). What the Raw Data Looks Like I've created an anonymized, raw subset of my actual data which you can view here. Part of my problem is that those who coded the data noticed that some students displayed multiple patterns. The coders' solution was to create enough columns (reason1, reason2, ...) to hold students with multiple patterns. That becomes important because the order (reason1, reason2) is arbitrary--two students (like student 41 and student 42 in my dataset) who correctly applied "dependency" should both register in an analysis, regardless of whether 3a appears in the reason column or the reason2 column. How Can I Best Structure Student Data? Part of my problem is that in the raw data, not all students display the same patterns, or the same number of them, in the same order. Some students may do just one thing, others may do several. So, an abstracted representation of example students might look like this: Note in the example above that student002 and student003 both are coded as "1b", although I've deliberately shown the order as different to reflect the reality of my data. My (Practical) Questions Should I concatenate reason1, reason2, ... into one column? How can I (re)code the reasons in R to reflect the multiplicity for some students? Thanks I realize this question is as much about good data conceptualization as it is about specific features of R, but I thought it would be appropriate to ask it here. If you feel it's inappropriate for me to ask the question, please let me know in the comments, and stackoverflow will automatically flood my inbox with sadface emoticons. If I haven't been specific enough, please let me know and I'll do my best to be clearer.

  • Is it possible to partition more than one way at a time in SQL Server?

    - by meeting_overload
    I'm considering various ways to partition my data in SQL Server. One approach I'm looking at is to partition a particular huge table into 8 partitions, then within each of these partitions to partition on a different partition column. Is this even possible in SQL Server, or am I limited to definining one parition column+function+scheme per table? I'm interested in the more general answer, but this strategy is one I'm considering for Distributed Partitioned View, where I'd partition the data under the first scheme using DPV to distribute the huge amount of data over 8 machines, and then on each machine partition that portion of the full table on another parition key in order to be able to drop (for example) sub-paritions as required.
