  • Converting a navbar to a tabbar app

    - by Nick
    Hey guys, I was wondering how to convert a NavigationController style app into a TabBarcontroller style app. I changed my mainwindow to not contain a navigationcontroller anymore (but a tabbarcontroller instead) and my delegate also appropiatly, but when I launch the app something still thinks I want a navigationController: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key navigationController.' Stack trace: #0 0x020fa004 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ #1 0x96fc0509 in objc_exception_throw #2 0x020ee1c1 in -[NSException raise] #3 0x000d8a78 in _NSSetUsingKeyValueSetter #4 0x000d84c5 in -[NSObject(NSKeyValueCoding) setValue:forKey:] #5 0x004fb4c8 in -[UIRuntimeOutletConnection connect] #6 0x020af92f in -[NSArray makeObjectsPerformSelector:] #7 0x004f9f7f in -[UINib instantiateWithOptions:owner:loadingResourcesFromBundle:] #8 0x004fbfcb in -[NSBundle(NSBundleAdditions) loadNibNamed:owner:options:] #9 0x0033b0a6 in -[UIApplication _loadMainNibFile] #10 0x0034482a in -[UIApplication _runWithURL:sourceBundleID:] #11 0x00341b88 in -[UIApplication handleEvent:withNewEvent:] #12 0x0033d6d3 in -[UIApplication sendEvent:] #13 0x003440b5 in _UIApplicationHandleEvent #14 0x0265aed1 in PurpleEventCallback #15 0x02092b80 in CFRunLoopRunSpecific #16 0x02091c48 in CFRunLoopRunInMode #17 0x0033be69 in -[UIApplication _run] #18 0x00345003 in UIApplicationMain #19 0x00002ec8 in main at main.m:14 Where can I specify the app is a tabbarcontrolled app, instead of a navigationbarcontrolled app?

  • Android Multiple objects in SimpleAdapter

    - by Adam Sherratt
    I have a need (unless you can think of a better way) of passing multiple objects to a custom list adapter. I know that I'm barking up the wrong tree here, and would appreciate someone setting me on the right course! Thanks playlistadapter = new MyPlaylistAdapter(MyApplication.getAppContext(), songsList, retained_songsList, folderMode, R.layout.file_view, new String[] { "songTitle","songAlbum", "songPath" }, new int[] { R.id.checkTextView, R.id.text2, R.id.text3 }); And my adapter class: public class MyPlaylistAdapter extends SimpleAdapter{ private ArrayList <Song> songsList = new ArrayList<Song>(); private ArrayList <Song> retained_songsList = new ArrayList<Song>(); private ArrayList<Song> playlistcheck = new ArrayList<Song>(); private String folderMode; private String TAG = "AndroidMediaCenter"; public MyPlaylistAdapter(Context context,List<Song> SongsList, List<Song> Retained_songsList, String FolderMode,int resource, String[] from, int[] to) { super(context, null, resource, from, to); songsList.clear(); songsList.addAll(SongsList); Log.i(TAG, "MyPlayListAdapter Songslist = " + songsList.size()); retained_songsList.clear(); retained_songsList.addAll(Retained_songsList); folderMode = FolderMode; } public View getView(int position, View convertView, ViewGroup parent) { //PlayListViewHolder holder; CheckedTextView checkTextView; TextView text2; TextView text3; if (convertView == null) { LayoutInflater inflater = (LayoutInflater) MyApplication.getAppContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

text2 = (TextView) convertView.findViewById(R.id.text2); text3 = (TextView) convertView.findViewById(R.id.text3); //convertView.setTag(holder); } else { //holder = (PlayListViewHolder) convertView.getTag();

  • Problem Rewriting URL's from HTTPS to HTTP using IIS7 URL Rewriter, when using Webforms ReturnURL=

    - by theminesgreg
    I took Jeff's Re-write rules from this post and the HTTP to HTTPS conversion works great. However, going back to HTTP is giving me problems because of the ReturnUrl= in the URL (I'm using webforms). Here's an example of the url: https://localhost/Login.aspx?ReturnUrl=%2f Here's the rewrite rule I'm using: <rule name="HTTPS to HTTP redirect for all other pages" stopProcessing="true"> <match url="^login\.aspx$" ignoreCase="true" negate="true" /> <conditions> <add input="{SERVER_PORT}" pattern="^443$" /> </conditions> <action type="Redirect" redirectType="Found" url="http://{HTTP_HOST}{REQUEST_URI}" /> </rule> Here's the resulting re-written URL: http://localhost/,/ Has anyone found a work around for this?

  • Latex label/ref for "fake" external figure

    - by Yannick Wurm
    Hello, some journals require each figure to be submitted in a separate document. However, they do want the figure legends to be listed in the main document. I was thus hoping to do something along these lines: \section{Figure Legends} \begin{description} \item[Figure \ref{fig:fireAntBiology}] \label{fig:fireAntBiology} bla bla ants \end{description} This would still permit to \ref the figure from the main text. However, it doesn't work (The \ref returns the number of section "Figure Legends"). The following correctly gives a different number to each "figure": \item[Figure \ref{fig:fireAntBiology}] \begin{figure} \caption{\label{fig:fireAntBiology}} \end{figure} bla bla ants However, it also places empty figure floats throughout the document. A solution should be straightforward. What am I missing? Any ideas? Thanks! yannick

  • Is there a design pattern for injecting methods into a class?

    - by glenn I.
    I have a set of classes that work together (I'm coding in javascript). There is one parent class and a number of child classes that are instantiated by the parent class. I have a number of clients of these classes that each need to add on one more methods to the parent or child classes. Rather than having each client inherit from these classes, which is doable but messy because of the child classes, I am having these clients pass functions into the parent class when they instantiate the main class. The main class creates the methods dynamically and the clients can call the methods like they were there all along. My questions are: is this a sensible thing to do? what would the design pattern be for what I am doing?

  • What are the implications of having an "implicit declaration of function" warning in C?

    - by SiegeX
    As the question states, what exactly are the implications of having the 'implicit declaration of function' warning? We just cranked up the warning flags on gcc and found quite a few instances of these warnings and I'm curious what type of problems this may have caused prior to fixing them? Also, why is this a warning and not an error. How is gcc even able to successfully link this executable? As you can see in the example below, the executable functions as expected. Take the following two files for example: file1.c #include <stdio.h> int main(void) { funcA(); return 0; } file2.c #include <stdio.h> void funcA(void) { puts("hello world"); } Compile & Output $ gcc -Wall -Wextra -c file1.c file2.c file1.c: In function 'main': file1.c:3: warning: implicit declaration of function 'funcA' $ gcc -Wall -Wextra file1.o file2.o -o test.exe $ ./test.exe hello world

  • jQuery class adding and removing with click and mouseleave

    - by danixd
    I just want to control a div by toggling a class on click, as well as removing it when the mouse leaves the div. I had it working with mouseout, but when I entered over a child element, the mouseOut triggered, so I know I need to use mouseleave. I am just unsure how incorporate telling jQuery the mouse has entered. Yes I am new to this! Here is my code: $(function(){ $('.main').click(function() { $(this).toggleClass('activated'); }); }); $(function(){ $('.main').mouseleave(function() { $(this).removeClass('activated'); }); });

  • How to keep an Hibernate's Session open until the page is rendered

    - by Neuquino
    I'm having the following problem: I'm using Oracle ADF for the view and controller of my app. With OpenSessionInViewFilter, I intercept the request and open an Hibernate's Session, and it is closed as soon as the bean's method finishes. What I need is to keep the Session opened until the page is rendered, because in my JSP y use the lazy attributes of the object i load from the DB. For example: When I enter index.jspx the IndexBean#main() is executed: public class IndexBean{ private DBObject myDBObject; public String main(){ this.myDBObject = this.myDAO.loadObjectFromDB(); return null; } } in index.jspx I have: ... <af:inputText value="#{myDBObject.lazyAttribute}" /> ... I'd like that the Hibernate's Session keeps open until the af:inputText is processed. Is this possible? How? Thanks in advance

  • Removing part of a branch

    - by benPearce
    In our codebase we are using the following structure, using TFS / - Build - Development - Dev1 - Dev2 - Main - Releases - Rel1 - Rel2 The Development and Releases sections contain branches off main. The Build section sits outside the branching. Within each of the branches there is a section which should not have been included within the branching which I would like to move under Build. Is it possible to move this section out and remove its branching information? If I do a rename what impact might this have when creating new branches or merging?

  • Instrumenting Database Access

    - by Whisk
    Jeff mentioned in one of the podcasts that one of the things he always does is put in instrumentation for database calls, so that he can tell what queries are causing slowness etc. This is something I've measured in the past using SQL Profiler, but I'm interested in what strategies other people have used to include this as part of the application. Is it simply a case of including a timer across each database call and logging the result, or is there a 'neater' way of doing it? Maybe there's a framework that does this for you already, or is there a flag I could enable in e.g. Linq-to-SQL that would provide similar functionality. I mainly use c# but would also be interested in seeing methods from different languages, and I'd be more interested in a 'code' way of doing this over a db platform method like SQL Profiler.

  • Silverlight Isolated Storage and loading big files

    - by Thomas Joulin
    In a Windows Phone 7 application, I would like to query a big XML file (list of cities) stored using Isolated Storage. If I do that this way, will the file be loaded to memory ( 5 mo) ? If so, what other solution do I have? Edit: More details. I want to use AutoCompleteBox (http://www.jeff.wilcox.name/2008/10/introducing-autocompletebox/), but instead of using a web service (this is fixed data, no need to be online), I want to query a file/database/isolated storage... I have a fixed list of cities. I said in the comments it's 40k, but it finally seems closer to 1k rows.

  • sbt: "test" works "test:run" not

    - by Martin
    I try to establish a build pipeline on Jenkins with a Play(2.0.2) project. As I want to just build the sources once and use the classes for downstream builds, I now have created a "compile"-job, that runs "sbt test:compile". That works so far. The next job should then just run the compiled tests. If I use "sbt test" it works as expected, but compiles the sources again. But if I try to run "sbt test:run" it says: [info] Loading project definition from ~/myproject/project [info] Set current project to myproject (in build file: ~/myproject/) java.lang.RuntimeException: No main class detected. at scala.sys.package$.error(package.scala:27) [error] {file:~/myproject/test:run: No main class detected. The same happens locally. I can run "sbt test" but not "sbt test:run". Same error. Is there someone who can point me to the right direction?

  • c++ and c# speed compared

    - by Mack
    I was worried about C#'s speed when it deals with heavy calculations, when you need to use raw CPU power. I always thought that C++ is much faster than C# when it comes to calculations. So I did some quick tests. The first test computes prime numbers < an integer n, the second test computes some pandigital numbers. The idea for second test comes from here: Pandigital Numbers C# prime computation: using System; using System.Diagnostics; class Program { static int primes(int n) { uint i, j; int countprimes = 0; for (i = 1; i <= n; i++) { bool isprime = true; for (j = 2; j <= Math.Sqrt(i); j++) if ((i % j) == 0) { isprime = false; break; } if (isprime) countprimes++; } return countprimes; } static void Main(string[] args) { int n = int.Parse(Console.ReadLine()); Stopwatch sw = new Stopwatch(); sw.Start(); int res = primes(n); sw.Stop(); Console.WriteLine("I found {0} prime numbers between 0 and {1} in {2} msecs.", res, n, sw.ElapsedMilliseconds); Console.ReadKey(); } } C++ variant: #include <iostream> #include <ctime> int primes(unsigned long n) { unsigned long i, j; int countprimes = 0; for(i = 1; i <= n; i++) { int isprime = 1; for(j = 2; j < (i^(1/2)); j++) if(!(i%j)) { isprime = 0; break; } countprimes+= isprime; } return countprimes; } int main() { int n, res; cin>>n; unsigned int start = clock(); res = primes(n); int tprime = clock() - start; cout<<"\nI found "<<res<<" prime numbers between 1 and "<<n<<" in "<<tprime<<" msecs."; return 0; } When I ran the test trying to find primes < than 100,000, C# variant finished in 0.409 seconds and C++ variant in 5.553 seconds. When I ran them for 1,000,000 C# finished in 6.039 seconds and C++ in about 337 seconds. Pandigital test in C#: using System; using System.Diagnostics; class Program { static bool IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return false; } return digits == (1 << count) - 1; } static void Main() { int pans = 0; Stopwatch sw = new Stopwatch(); sw.Start(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } sw.Stop(); Console.WriteLine("{0}pcs, {1}ms", pans, sw.ElapsedMilliseconds); Console.ReadKey(); } } Pandigital test in C++: #include <iostream> #include <ctime> using namespace std; int IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return 0; } return digits == (1 << count) - 1; } int main() { int pans = 0; unsigned int start = clock(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } int ptime = clock() - start; cout<<"\nPans:"<<pans<<" time:"<<ptime; return 0; } C# variant runs in 29.906 seconds and C++ in about 36.298 seconds. I didn't touch any compiler switches and bot C# and C++ programs were compiled with debug options. Before I attempted to run the test I was worried that C# will lag well behind C++, but now it seems that there is a pretty big speed difference in C# favor. Can anybody explain this? C# is jitted and C++ is compiled native so it's normal that a C++ will be faster than a C# variant. Thanks for the answers!

  • Has anyone noticed that a WPF file dialog will pass through a click to the UI when double clicking t

    - by Ben
    I have some buttons on my WPF UI and I also need to choose files from time to time. I kept noticing strange problems where when I double-click an item in the file dialog, a button on the main UI would also get clicked. After experimenting, it seems that if you line up an item in the file dialog with a button behind it on the main UI and double click to select the file, it will single-click the button behind it as well. Has anyone else noticed this, or is it just a freak bug with the way I have my UI laid out?

  • newbie problems with codeigniter

    - by Patrick
    hi, i'm trying to learn codeigniter (following a book) but don't understand why the web page comes out empty. my controller is class Welcome extends Controller { function Welcome() { parent::Controller(); } function index() { $data['title'] = "Welcome to Claudia's Kids"; $data['navlist'] = $this->MCats->getCategoriesNav(); $data['mainf'] = $this->MProducts->getMainFeature(); $skip = $data['mainf']['id']; $data['sidef'] = $this->MProducts->getRandomProducts(3, $skip); $data['main'] = "home"; $this->load->vars($data); $this->load->view('template'); } the view is: <--doctype declaration etc etc.. --> </head> <body> <div id="wrapper"> <div id="header"> <?php $this->load->view('header');?> </div> <div id='nav'> <?php $this->load->view('navigation');?> </div> <div id="main"> <?php $this->load->view($main);?> </div> <div id="footer"> <?php $this->load->view('footer');?> </div> </div> </body> </html> Now I know the model is passing back the right variables, but the page appears completely blank. I would expect at least to see an error, or the basic html structure, but the page is just empty. Moreover, the controller doesn't work even if I modify it as follows: function index() { echo "hello."; } What am I doing wrong? Everything was working until I made some changes to the model - but even if I delete all those new changes, the page is still blank.. i'm really confused! thanks, P.

Is there a way for my main thread to spawn a worker thread and monitor that worker thread. If worker thread succeeds, well and good. If it hangs , the main thread could log error message and continue. How can I simulate in my test code that a worker thread is hanging. please let me know what could the code look like.

  • Can't access font resource in Silverlight class library

    - by Matt
    I have a reasonably large Silveright 3.0 project on the go, and I'm having issues accessing a couple of custom font resources from within one of the assemblies. I've got a working test solution where I have added a custom font as a resource, and can access it fine from XAML using: <TextBlock Text="Test" FontFamily="FontName.ttf#Font Name" /> The test solution consists of the TestProject.Application and the TestProject.Application.Web projects, with all the fun and games obviously in the TestProject.Application project However, when I try this in my main solution, the fonts refuse to show in the correct type face (instead showing in the default font). There's no difference in the way the font has been added to project between the test solution and the main solution, and the XAML is identical. However, there is a solution layout difference. In the main solution, as well as having a MainApp.Application and MainApp.Application.Web project, I also have a MainApp.Application.ViewModel project and a MainApp.Application.Views project, and the problem piece of XAML is the in the MainApp.Application.Views project (not the .Application project like the test solution). I've tried putting the font into either the .Application or .Application.Views project, tried changing the Build Action to Content, Embedded Resource etc, all to no avail. So, is there an issue accessing font resources from a child assembly that I don't know about, or has anyone successfully done this? My long term need will be to have the valid custom fonts being stored as resources in a separate .Application.FontLibrary assembly that will be on-demand downloaded and cached, and the XAML controls in the .Application.Views project will need to reference this FontLibrary assembly to get the valid fonts. I've also tried xcreating this separate font library assembly, and I can't seem to get the fonts from the second assembly. As some additional information, I've also tried the following font referencing approaches: <TextBlock Text="Test" FontFamily="/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;component/FontName.ttf#Font Name" /> And a few similar variants with different assembly references/sub directories/random semi colons. And so far nothing works... anyone struck this (and preferably solved it)?

  • Updating Label on previously loaded view?

    - by fuzzygoat
    I am working on a simple app tab-bar based application that has two views. The first is the main application and the second is a simple instruction screen. What I am trying to do is create a update a label on that second screen as things change in the main app. Because the second screen is only simple with one label and some text I am not unloading it once its loaded. After the first viewDidLoad I can update the label just fine, but after that is there a way to catch successive view switches from the tab-bar menu so I can update the label? many thanks gary

Using valgrind --tool=memcheck --leak-check=yes ./a.out I keep getting: ==4506== 40 bytes in 10 blocks are definitely lost in loss record 2 of 9 ==4506== at 0x4024C1C: malloc (vg_replace_malloc.c:195) ==4506== by 0x40782E3: g_malloc (in /lib/libglib-2.0.so.0.2200.3) ==4506== by 0x4090CA8: g_strdup (in /lib/libglib-2.0.so.0.2200.3) ==4506== by 0x8048722: add_inv (dup.c:26) ==4506== by 0x80487E6: main (dup.c:47) ==4506== 504 bytes in 1 blocks are possibly lost in loss record 4 of 9 ==4506== at 0x4023E2E: memalign (vg_replace_malloc.c:532) ==4506== by 0x4023E8B: posix_memalign (vg_replace_malloc.c:660) ==4506== by 0x408D61D: ???

  • Android 2.1: Muliple Handlers in a Single Activity

    - by Soumya Simanta
    Hi, I've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handlerMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? public void onCreate() { this.handler1 = new Handler() { @Override public void handleMessage(Message msg) { //operation 1 : some operation with instanceVariable1 super.handleMessage(msg); } }; this.handler2 = new Handler() { @Override public void handleMessage(Message msg) { //Operation 2: some operation with instanceVariable1 super.handleMessage(msg); } }; this.handler3 = new Handler() { @Override public void handleMessage(Message msg) { //Operation 3: some operation with instanceVariable1 super.handleMessage(msg); } }; }

  • YAGNI and database creation scripts

    - by Daniel Straight
    Right now, I have code which creates the database (just a few CREATE queries on a SQLite database) in my main database access class. This seems unnecessary as I have no intention of ever using the code. I would just need it if something went wrong and I needed to recreate the database. Should I... Leave things as they are, even though the database creation code is about a quarter of my file size. Move the database-creation code to a separate script. It's likely I'll be running it manually if I ever need to run it again anyway, and that would put it out-of-sight-out-of-mind while working on the main code. Delete the database-creation code and rely on revision control if I ever find myself needing it again.

  • SFML 2.0 crashes anytime a method is called

    - by Ken
    This code generates an exception: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; clock.getElapsedTime(); return 0; } However, this doesn't crash: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; return 0; } I'm using SFML 2.0, Windows 7, MinGW 4.70 (Code::Blocks). I don't know why, I followed all instructions to link the libraries and nothing seems to be working. I might be missing something simple through my anger (I've been trying to run sample code for a week, nothing has been working), so can anybody throw me a bone?
