• pitchbend (varispeed) audio with iPhone SDK's AudioUnit

  - by fetzig

  hi, I'm trying to manipulate the speed (and pitch) of a sound while playing. so i played around with iphone sdk's AudioUnit. downloaded iPhoneMultichannelMixerTest and tried to add an AUComponent to the graph (in this case a formatconverter). but i get (pretty soon) following error when building: #import <AudioToolbox/AudioToolbox.h> #import <AudioUnit/AudioUnit.h> ... AUComponentDescription varispeed_desc(kAudioUnitType_FormatConverter, kAudioUnitSubType_Varispeed, kAudioUnitManufacturer_Apple); ^^ error: 'kAudioUnitSubType_Varispeed' was not declared in this scope. any ideas why? the documentation on this topic doesn't help me at all (just api doc isn't very helpful when having no clue about the concept behind). there are no examples on how to wire these effects together and manipulating there properties...so maybe i'm totally wrong, anyway any hint is great. thx for help.

• How to get strptime to raise ArgumentError with garbage trailing characters

  - by Matt Briggs

  We have to handle user specified date formats in our application. We decided to go with Date.strptime for parsing and validation, which works great, except for how it just ignores any garbage data entered. Here is an irb session demonstrating the issue ree-1.8.7-2010.01 > require 'date' => true ree-1.8.7-2010.01 > d = Date.strptime '2001-01-01failfailfail', '%Y-%m-%d' => #<Date: 4903821/2,0,2299161> ree-1.8.7-2010.01 > d.to_s => "2001-01-01" what we would like, is behavior more like this ree-1.8.7-2010.01 > d = Date.strptime '2001failfailfail-01-01', '%Y-%m-%d' ArgumentError: invalid date Any suggestions would be appreciated

• Speeding up CakePHP

  - by DavidYell

  I've been a keen fan and user of CakePHP for about 2.5 years now, but the main bugbear that most fellow developers level at the framework is that it's slow, and the dispatch cycle takes too long to make it a viable solution for production environments. I'm hoping that this question will inspire people to share their tips, tricks and hacks for speeding up CakePHP performance. The blog post I most often refer to is here, http://www.pseudocoder.com/archives/8-ways-to-speed-up-cakephp-apps Which has great tips, but there must be more out there! So please feel free to share your thoughts on making this excellent framework that much more nimble!

• VB.NET ASP.NET Web Application woes (VS 2008)

  - by typoknig

  Hi all, I am making my first web application with ASP.NET and I am having a rough time. I have previously created the application I am working on as a Windows Form application and it works great, but I am having problems with the HTML side of things in the web application. My issues are pretty minor, but very annoying. I have worked with websites before and CSS, but as far as I can tell I do not have direct access to a CSS when creating a web application in VS 2008. My biggest issue is the positioning of components that I have dragged onto the "Default.aspx" form. For instance, how am I supposed to float a panel next to another one if I don't have a CSS, or how am I to correctly position a label?

• Jquery DateJs, is there validation for full date?

  - by Cesar Lopez

  Hi all, I just find out about the power of date js, And its great!!! As I am a newbie I was wondering if there is any kind of general validitation for different types of full dates. eg. var d1 = Date.parse('2000-10-18, 10:06 AM'); alert(d1.toString('HH:mm')); If date is ('200-10-18, 10:06 AM'), of course it doesn't like it. So my question is if there is any quick way to validate the full date, rather than having to validate one by one. Thanks.

• Can anyone tell me what the authors mean on this line?

  - by Anirudh Goel

  i was going through this link: FAT16 Basics to Assemble Clusters. I have read the structures involved in defining a directory entry in FAT. Now when giving the example for a FAT16 File, it says the data cluster is 0x03 for the example file MyFile.txt. Which means if we logically compute the Data Cluster we will be able to reach to the first node which happens to be cluster no 3. But what I fail to understand is what the author is trying to say in the next line where it says What we can see in the File Allocation Table at this moment? How suddenly we reach to the File Allocation Table? Weren't we already there when we were going through the information of Myfile.txt? I couldn't find any reason how suddenly the author jumped to an offset location of 00000200 and is identifying the emptiness of the clusters. It will be great if someone can help me understand. Thanks

• Linking IronPython to WPF

  - by DonnyD

  I just installed VS2010 and the great new IronPython Tools extension. Currently this extension doesn't yet generate event handlers in code upon double-clicking wpf visual controls. Is there anyone that can provide or point me to an example as to how to code wpf event handlers manually in python. I've had no luck finding any and I am new to visual studio. Upon generating a new ipython wpf project the auto-generated code is: import clr clr.AddReference('PresentationFramework') from System.Windows.Markup import XamlReader from System.Windows import Application from System.IO import FileStream, FileMode app = Application() app.Run(XamlReader.Load(FileStream('WpfApplication7.xaml', FileMode.Open))) and the XAML is: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WpfApplication7" Height="300" Width="300"> <Button>Click Me</Button> </Window> Any help would be appreciated.

• Using ScriptCombining through a ScriptManager on a Master Page

  - by Hmobius

  ASP.NET 3.5 SP1 adds a great new ScriptCombining feature to the ScriptManager object as demonstrated on this video. However he only demonstrates how to use the feature with the ScriptManager on the same page. I'd like to use this feature on a site where the scriptmanager is on the master page but can't figure out how to add the scripts I need for each page programmatically to the manager. I've found this post to use as a starting point, but I'm not really getting very far. can anyone give me a helping hand? Thanks, Dan

• Sql Server copying table information between databases

  - by Andrew

  Hi, I have a script that I am using to copy data from a table in one database to a table in another database on the same Sql Server instance. The script works great when I am connected to the Sql Server instance as myself as I have dbo access to both databases. The problem is that this won't be the case on the client's Sql Server. They have seperate logins for each database (Sql Authentication Logins). Does anyone know if there is a way to run a script under these circumstances. The script would be doing something like. use sourceDB Insert targetDB.dbo.tblTest (id, test_name) Select id, test_name from dbo.tblTest Thanks

• Implements an Undo/Redo in MVC

  - by bnabilos

  Hello, I have a Java application and I want to implement an Undo/Redo option. the value that I want to stock and that I want to be able to recover is an integer. My Class Model implements the interface StateEditable and I have to redefine the 2 functions restoreState(Hashtable<?, ?> state) and storeState(Hashtable<Object, Object> state) but I don't know what to put on them. It will be really great if somebody can help me to do that. These are the first lines of my Model class, the value that I want to do an undo/redo on it is value public class Model extends Observable implements StateEditable { private int value = 5; private UndoManager undoRedo = new UndoManager(); final UndoableEditListener editListener = new UndoableEditListener() { public void undoableEditHappened(UndoableEditEvent evt) { undoRedo.addEdit(evt.getEdit()); } }; @Override public void restoreState(Hashtable<?, ?> state) { } @Override public void storeState(Hashtable<Object, Object> state) { } }

• How to use forfiles (or similar) to delete files older than n days, but always leaving most recent n

  - by Aidan Whitehall

  (Using Windows 2000 and 2003 Server) We use forfiles.exe to delete backup .zip files older than n days, and it works great (command is a bit like below) forfiles -p"C:\Backup" -m"*.zip" -c"cmd /c if @ISDIR==FALSE del \"@PATH\@FILE\"" -d-5 If a .zip file fails to be created, I'd like to ensure that we don't end up with 0 .zip files in the backup after 5 days. Therefore, the command needs to be: "delete anything older than 5 days, but ALWAYS keep the most recent 5 files, EVEN if they themselves are older than 5 days" We can use forfiles.exe or another solution (although anything that is a slick one-liner is ALWAYS preferable to a script file). Thanks!

• Equivalent of describeType for Flex Component EVENTS

  - by Joshua

  Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

• Automated testing of a website for IE7 javascript errors?

  - by Andreas Bonini

  This week I decided to add a new element to a javascript array by copying a similar one from a previous line; unfortunately I forgot to remove the comma so the end result was something like var a = [1, 2, 3,]. The code went live late Friday afternoon just before everyone left for the week-end, and it completely broke everything in Internet Explorer 7 (and lower I assume) since it's such a great browser. Since there was no one to read emails (week-end) it went unnoticed for quite a while, and I really don't want something like this to happen again (especially in my code).. This is not the first of weird IE7 problems; I was wondering if there was a way to automatically test key pages looking for javascript or css errors, or really anything that IE8 would output in its new console in development tools. If there isn't, what do you usually do? You test the website after every change with all the browsers you support? (Something I'll do from now, at least for IE, if there is no way to run automated tests)

• Finding the best folder for all users on a Windows machine

  - by reallyjoel

  We are making a game which will add a level editor feature soon. We want the user to be able to put levels he's downloaded in a folder and then play it in the game, without any hassle. So, we're looking for a folder that anybody can find, open, write, read, and is multiuser. On Windows Vista / 7, the folder /Users/Public/ look like a great candidate. However, It's not listed in the .net enum System.Environment.SpecialFolder. I have went through them all, and checked what they yield on different Windows versions, and none live up to my requirements. I did find Environment.SpecialFolder.CommonApplicationData, that kinda works, but that folder is hidden (C:\ProgramData) and I assume most users don't display hidden folders. As it stands now, it looks like we'll have to settle for the personal documents folder, but we'd really like a multi user folder? Anyone have any tips? (Hard coding c:\Users\Public\ is out of the question, it will only work on english systems)

• Where does Visual Studio stores the default browser to use in debug?

  - by Fabian Vilers

  Hi all, I'm using Firefox as my default browser but when working in Visual Studio, I'd like to fire up IE when I go in debug. We all know that in MVC application, there's no way to choose the default browser unless you add a web form file, right click it, select browse with and then force a browser to be the default one. Great. My simple question is: where does VS stores the browser I just tell him to use (registry? project file? some xml config file?) I'm asking because VS loose this preference several times a month. I'm fed up with making the brower trick again and again. Thanks in advance, Fabian

• How to get Resharper to show a Refactoring that it already has.

  - by AngryHacker

  Whenever Resharper encounters code like this: (treeListNode.Tag as GridLine).AdvertiserSeparation = 5; it presents you with a possible fix (since treeListNode.Tag as GridLine might be null). It says: 'Replace with Direct Cast', which turns the code into the following: ((GridLine) treeListNode.Tag).AdvertiserSeparation = 5; This is great. However, when it encounters code like this: GridLine line = treeListNode.Tag as GridLine; line.AdvertiserSeparation = 5; Resharper simply displays a warning 'Possible System.NullReferenceException', but does not offer me to 'Replace with Direct Cast'. Is there a way to make Resharper offer me this refactoring, since it already has it?

• SSIS - Update flag of selected rows from more than one table

  - by Rob Bowman

  Hi I have a SSIS package that copies data from table A to table B and sets a flag in table A so that the same data is not copied subsequently. This works great by using the following as the SQL command text on the ADO Net Source object: update transfer set ProcessDateTimeStamp = GetDate(), LastUpdatedBy = 'legacy processed' output inserted.* where LastUpdatedBy = 'legacy' and ProcessDateTimeStamp is not null The problem I have is that I need to run a similar data copy but from two sources table, joined on a primary / foreign key - select from table A join table B update flag in table A. I don't think I can use the technique above because I don't know where I'd put the join! Is there another way around this problem? Thanks Rob.

• Delphi 2010: whatever happened to TRTTIConstructor?

  - by conciliator

  I've got two questions (of which at least one is regarding RTTI in D2010 and dynamic instancing) I was reading what appears to be the foils for a conference talk by Barry Kelly, and found on p. 13 something that looked really interesting: TRTTIConstructor.Invoke. In an adjacent bullet point, on finds "Dynamically construct instances without needing virtual constructors and metaclasses". This seems like a great feature (and exactly what I need, btw)! However, when I look in the D2010 docs (ms-help://embarcadero.rs2010/vcl/Rtti.html), I can't find it. Did it get revoked? What is the minimal way of creating an instance of a class, provided the class name is stored in a string?

• dynamic dashboard interface

  - by user208081

  I want to create an interface similar to the following in Silverlight. http://demos6.dundas.com/Silverlight/ I need to create a dashboard where different elements can be re-arranged using Silverlight. The dashboard elements can be different usercontrols that in turn may contain charts, guages, grids...... The user should be able to dynamically add and remove dashboard elements. The user should also be able to use drag and drop to reposition the dashboard elements. If there are some code samples to get me started, that will be great as we are just starting out on some Silverlight development. Thanks, Pratik

• Handle order dependence in for loops

  - by Matt

  Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width(); // Undefined! Or atleast not set yet.. } } Class B { private $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler

• How do I get the window id and tab number of a Terminal window using AppleScript via the ScriptingBr

  - by Gavin Brock

  I can open a Terminal tab using the following AppleScript: tell application "Terminal" set myTab to do script "exec sleep 1" get myTab end tell This returns a string like: tab 1 of window id 3263 of application "Terminal". This is great, I can see the window id 3263 and tab number 1 (although I don't know how to query myTab to get only these values). In the Cocoa ScriptingBridge, I can do: SBApplication *terminal; SBObject *tab; terminal = [SBApplication applicationWithBundleIdentifier:@"com.apple.terminal"] tab = [terminal doScript:@"exec sleep 1" in:nil] How do I get the window id and tab number from the tab object?
