• g++ and c++0x specification support

  - by SepiDev

  although it's been said that the support for c++0x new features in g++ are in experimental mode, many gcc developer claimed that you can use most of the new features in your codes and get the program to work. but when I try to compile this simple program it results in segmentation fault. Why? #include <thread> #include <iostream> void my_thread_func() { std::cout<<"hello"<<std::endl; } int main() { std::thread t(my_thread_func); t.join(); } g++ -std=c++0x -Wall -o run main.cc

• How to restrict html body width when not displayed on iPhone?

  - by Curyous

  I have set up a web page to look good on the small screen of an iPhone, but when viewed on the desktop, and going right across the width of the browser, it looks terrible. Is there a way I can restrict the width to say, 480px when viewed on a big screen? I tried body { margin-left:auto; margin-right:auto; max-width:480px; } but it seems to just set the width at 480px, even on an iPhone on portrait mode.

• iphone/ipad application - taking screen shot

  - by satyam

  I successfully implemented an application that works on ipad as well as on iphone. In that I provided option to user to send the screen shot of the application as mail attachment. Even that is functioning well. But my code is taking screen shot irrespective of orientation. The image i'm getting is always in portrait mode. I want to take the screen shot depending on the orientation of ipad/iphone and send the image as attachment. I'm using following code to take the screen shot. UIGraphicsBeginImageContext(screenWindow.frame.size); [screenWindow.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

• read http header info in ASIHttpRequest asynchronous

  - by user262325

  Hello everyone One of my project is to download several large size files using ASIHTTPRequest in asynchronous mode. I hope to read the http returned header info to get the size of files. I know [request respsonseHeaders] (requestFinished: delegate method ) can do that. I tested and found that requestFinished: is only triggered when it completed the download of a whole single file. But I hope to access the function [request respsonseHeaders] before ASIHTTPRequest starting to download files (just when ASIHTTPRequest got the returned header info). I can not find the triggered event for this. Welcome any comment Thanks interdev

• Windows7 issue in mutli- tasking and memory

  - by Nitesh

  I seeming some problem in my windows OS recently, let me first say my system configuration. processor - Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66 GHz Installed memory (RAM) - 4.00 GB (3.00 GB usable) System type - 32 bit operating system I am using two OS in this system, first one is Windows7 and the other is centOS. Well, I am using this from a long time there was no problem , and all of a sudden since from couple weeks I am facing problems in my Windows7 OS. In windows7 i was nearing using multiple jobs almost every time i log in, there was no problem but now i don't no what happen I am not able to do multiple jobs at same time. For example- 1 I am now not able to listen to music in windows media player and view photo's. All of a sudden the system stops working and does not respond and then respond after 5mins and the music get played where it got stopped after 5 mins. 2 When i start browersing internet it hangs all of sudden and doesn't respond for 2 or 3 mins and gets loading. I mean it just happens for every operation i do in the system. Even now typing was also difficult, it gets hanged very frequently even though i am doing single task. I have never come across this kind of problem before. So the first thing i did was to see the useage of the processor and the memory. Well, i thick the useage of the processor was fine, for single task the useage was some where around 3 to 5%. Well, it was something weird i found in the memory, in spite of no task that i was running it was using somewhere around 34 to 41% of memory. So i opened the task manager and click on resource monitor in performance tab. And in the memory section of the monitoring tool i found the usage of my RAM, it was something like this. Hardware reserved - 1029 MB In Use - 1430 MB Modified - 49 MB Standby - 1566 MB free - 22 MB And i could also see Available 1588 MB Cached 1615 MB Total 3067 MB Installed 4096 MB well, this if all i could find out and i have no idea why my computer is acting so weird all of a sudden and the performance problem is growing day by day and i also don't know if there is problem in Bios, i have let it for default settings from long time. please help me and Thank you in advance for reading this and helping me.

• SQL Server 2008 - cannot register default instance MSSQLSERVER

  - by Paul Moss

  Hello, I have installed SQL Server 2008 Developer on Windows 7 64 bit. In Management Studio I cannot register the default instance MSSQLSERVER, it cannot find it although the service is running. I get the message: Cannot connect to PHOENIX\MSSQLSERVER. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) (Microsoft SQL Server, Error: 87) However Management Studio does show the SQL Server 2005 Express instance (that was installed with VS 2008 Pro) which appeared as already registered. I an using Windows Authentication as I installed it in mixed mode. Any ideas would be appreciated, many thanks paul

• Getting Raw XML From SOAPMessage in Java

  - by Daniel Lew

  I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get the raw XML from a SOAPMessage (or any Node) object. Here's a sample of the code I've got right now, and where I'm trying to grab the XML: @WebServiceProvider(wsdlLocation="SoapService.wsdl") @ServiceMode(value=Service.Mode.MESSAGE) public class SoapProvider implements Provider<SOAPMessage> { public SOAPMessage invoke(SOAPMessage msg) { // How do I get the raw XML here? } } Is there a simple way to get the XML of the original request? If there's a way to get the raw XML by setting up a different type of Provider (such as Source), I'd be willing to do that, too.

• Get C# Templates For VS 2008 Shell

  - by Onorio Catenacci

  I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).

• OGRE: Non-Standard Resolution

  - by Rafid K. Abdullah

  I am using OGRE to make a re-rendering of the film, which has a wide aspect ratio (around 1.85). The OGRE dialog seems to be showing the standard full screen resolution by default (800/600, 1024/768, etc.), but those obviously have aspect ratios of 1.333 or around that. But as long as I am not running full screen mode, why should I be restricted to these screen sizes only? I can definitely change the viewport size, but that would make it difficult for me to generate the video later. Any idea?

• Praat scripting

  - by Binaryrespawn

  Hi all, I am trying to write a praat script to do preprocessing on hundreds of speach samples. I need to extract speech features from each sample and feed these as imputs into a feed-forward neural network. I have already constructed the network using math-lab. However, learing to script in praat is proving to be quite a challenge given my time constraints. Some of my samples are 0.01 to 0.03 seconds in length, I was looking at standardising the duration for all samples using Pitch Synchronous OverLap-Add(PSOLA). However this will be very tedious if I were to do this for every sample. Is there any script that can read in all of my files and perform the operations in a batch mode? Any guidance will be surelly appreaciated. Regards.

• ghc can't find my cabal installed packages

  - by nont

  I've installed ghc 6.12.3, and then the Haskell Platform. I'm trying to compile a test program: $ ghc test.hs test.hs:3:0: Failed to load interface for `Bindings': Use -v to see a list of the files searched for. so, naturally, I do cabal install Bindings Which works fine, and places the package in ~/.cabal/lib/bindings-0.1.2 The problem is, that when I go to compile again with ghc, it still doesn't find the package I've installed with cabal. compiling in verbose mode gives: ghc -v test.hs Using binary package database: /home/ludflu/ghc/lib/ghc-6.12.3/package.conf.d/package.cache Using binary package database: /home/ludflu/.ghc/x86_64-linux 6.12.3/package.conf.d/package.cache As suggested by another stackoverflow user, I tried: ghc-pkg describe rts > rts.pkg vi rts.pkg # add the /home/ludflu/.cabal/lib to `library-dirs` field ghc-pkg update rts.pkg But to no avail. How to I add the .cabal to the list of package directories to search? Thank you!

• Display data requested by an ajax.load() call once complete, not during the call.

  - by niczoom

  My jQuery code (using ajax) request's data from a php script (pgiproxy.php) using the following function: function grabPage($pageURL) { $homepage = file_get_contents($pageURL); echo $homepage; } I then extract the html code i need from the returned data using jQuery and insert it into a div called #BFX, as follows: $("#btnNewLoadMethod1").click(function(){ $('#temp1').load('pgiproxy.php', { data : $("#formdata").serialize(), mode : "graph"} , function() { $('#temp').html( $('#temp1').find('center').html() ); $('#BFX').html( $('#temp').html() ); }); }); This works fine. I get the html data (which is a gif image) i need displayed on screen in the correct div. The problem is i can see the html data loading into the div (dependant on network speed), but what I want is to insert the extracted html code into #BFX ONLY when the ajax request has fully completed.

• What option in Visual Studio let catching exception where it occurred?

  - by macias

  VS 2010. The same WPF project, debug mode, two computers: A -- when exception occurrs the caret is placed at the point of exception B -- when the exception occurrs, correct exception is placed but always caret is placed at "win.ShowDialog()" in App.xaml.cs -- this is main entry for showing & running my application, in such case it is very tiresome to track down where the exception occurred What kind of settings control such behaviour? Of course I would like to switch B, so when exception hits I would be place at the point of exception, not at the main entry.

• Binding Properties.Settings to Textbox fails

  - by user268098

  I would like to define a key & value in Settings.settings and bind the value by declaration in the XAML (not in the code behind by command). Here's what I've been trying in vain: Create a WPF project "Exp1" with Visual Studio Express 2010. Set one key named "TextFromSettings" to the value "Some Text from Setting". Add the attribute xmlns:p="clr-namespace:Exp1.Properties;assembly=Exp1" to the tag. Add Text="{Binding Path=TextFromSettings, Mode=TwoWay, Source={x:Static p:Settings.Default}}" to the tag Now, the preview window shows the text, however, the compiler fails: "Error 1 Cannot find the type 'Settings'. Note that type names are case sensitive." Where am I going wrong?

• ignore certain buffers using iswitchb

  - by robUK

  Hello, GNU Emacs 23.1 I am using iswitchb. However, when I press c-x b I get a list of buffers. However, I don't want to display one like scratch, Messages, GNU Emacs, etc. Just the buffers I have opened myself. So I am looking for a way to ignore these buffers. This is what I have in my configuration. However, it doesn't ignore the buffers I don't want. Have I done anything wrong? ;; Setup iswitchb to select different buffers, ignore buffers to reduce list (iswitchb-mode 1) (setq iswitchb-buffer-ignore '("*scratch*")) (setq iswitchb-buffer-ignore '("*Messages*")) (setq iswitchb-buffer-ignore '("*GNU Emacs*")) (setq iswitchb-buffer-ignore '("*compilation*")) Many thanks for any suggestions,

• Loading different portrait/landscape UIViews

  - by Tronic

  Hi, I have following View COntroller structure: ScrollViewController LandscapeViewController PortraitViewController Each with its own .nib The app starts in landscape mode where many landscape views are added to a scrollview. Each landscape view has its specific portrait view, so I have to assign like ID's to each of this views. Can you tell me, how I can load the specific portrait view for each landscape view when rotating the device? Do I have to make two scroll views? One for landscape, one for portrait? Or is it possible to just scroll through the landscape scrollview an load just one portrait view with the right content based on an ID? How could I implement that? The data comes from a property list. Thanks in advance!

• Can run Javascript but not jQuery?

  I'm running into a strange problem - I tried running a basic function in JS and jQuery, and while the former worked, the latter didn't. JS - okay alert('Works'); jQuery - not okay $(document).ready({ alert('Works'); }); Here's some facts: My references to the jQuery library are correct (And pretty sure my Internet connection is steady :) I'm using a CDN - CloudFlare to be exact, but I've switched development mode on and Rocket Loader off - so all the code I've uploaded to the server is WYSIWYG (CloudFlare adds some stuff in the tags if you leave Rocket Loader on. I tried running the alert code in the head section, and elsewhere in the body tags, to no avail. What could have possibly gone wrong?
