• Why does the last row of my tableview not align to the bottom of the screen

  - by Liam

  I have a view which consists of a tableview and a navigation bar. For my tableview I have implemented a 'Load more' row which will load current + pagesize every time it is clicked The way the loading works is very simple, every time it is clicked I just request the amount of rows I want to display e.g. 5, 10, 15 and so on. This request populates an array and I call [self.tableView reloadData] The issue I am experiencing is that when I go to the tableview the first time, it correctly loads and displays the tableview. However, if I 'Load more' it returns the correct amount and displays the correct number of cells but the last cell will not fit properly at the bottom of the screen, about 1/2 of it (or roughly the size of the navigation bar of the cell) appears below the bottom of the screen. I thought it was sufficient to just tell the tableview to reload itself. Do I need to use [self.tableView insertRowsAtIndexPaths ...] to do this.

• Download and replace Android resource files

  - by Casebash

  My application will have some customisation for each company that uses it. Up until now, I have been loading images and strings from resource files. The idea is that the default resources will be distributed with the application and company specific resources will be loaded from our server after they click on a link from an email to launch the initialisation intent. Does anyone know how to replace resource files? I would really like to keep using resource files to avoid rewriting a lot of code/XML. I would distribute the application from our own server, rather than through the app store, so that we could have one version per company, but unfortunately this will give quite nasty security warnings that would concern our customers.

• C++ function-pointer and inheritance

  - by pingvinus

  In parent class I have function, that operates under an array of functions, declared in child-class, number of functions for every child-class may vary. But since every function uses some object-variables, I can't declare them as static. I've try to do something like this: class A { public: typedef int (A::*func)(); func * fs; void f() { /*call functions from this->fs*/ } }; class B : public A { public: int smth; B(int smth) { this->smth = smth; this->fs = new func[1]; fs[0] = &B::f; } int f() { return smth + 1; } }; But, obviously it doesn't work. Any suggestions?

• How to play sound from libray in AS3?

  - by Ullallulloo

  In Flash 10/AS3, I added some sound and it seems to be working alright, but I think I'm doing it wrong. I imported the sound into the library, but I believe that it's reloading it from the folder with the swf/sound. I'm loading them like so: var request1:URLRequest = new URLRequest("CLICK8C.mp3"); clickSound = new Sound(); clickSound.addEventListener(Event.COMPLETE, completeHandler); clickSound.load(request1); Is there a way to get it to just load it from the library?

• Sinatra Set Settings (Ruby)

  - by JP

  Using Sinatra in Ruby you can set the server's settings by doing: set :myvariable, "MyValue" and then access it anywhere in templates etc with settings.myvariable. In my script I need to be able to re-set these variables falling back to a bunch of defaults. I figured the easiest way to do this would be to have a function that performs all the sets calling it at the start of the Sinatra server and when I need to make the alterations: class MyApp < Sinatra::Application helpers do def set_settings s = settings_from_yaml() set :myvariable, s['MyVariable'] || "default" end end # Here I would expect to be able to do: set_settings() # But the function isn't found! get '/my_path' do if things_go_right set_settings end end # Etc end As explained in the code above, the set_settings function isn't found, am I going about this the wrong way?

• Segfault when calling a method c++

  - by shuttle87

  I am fairly new to c++ and I am a bit stumped by this problem. I am trying to assign a variable from a call to a method in another class but it always segfaults. My code compiles with no warnings and I have checked that all variables are correct in gdb but the function call itself seems to cause a segfault. The code I am using is roughly like the following: class History{ public: bool test_history(); }; bool History::test_history(){ std::cout<<"test"; //this line never gets executed //more code goes in here return true; } class Game{ private: bool some_function(); public: History game_actions_history; bool local_variable; }; bool Game::some_function(){ local_variable = game_actions_history.test_history(); if (local_variable == true){ return true; } else{ return false; } } Any tips or advice is greatly appreciated!

• Dynamically load _gallery_ (not album) in SlideShowPro using SWFObject

  - by bccarlso

  Hi all. I have been successful in dynamically loading an album in SSP before, but using SSP Standalone. I did it like this: var flashvars = { xmlFilePath: "http://site.com/ssp_director/images.php?album=5" } What I'm looking to do now, though, is dynamically load a gallery when the page loads, using text entered in the javascript, or flashvars I'd assume. I'm using ActionScript 3 with this, so I'm not sure if I have to do something to the SSP instance in Flash. I'm not very good with AS3, so following advice or tutorials is about all I can muster. I'm also using SSP Director, so my gallery XML URLs would be similar to above in the example code. I'd be elated if this is possible, otherwise I will have to find an alternative solution. Thanks so much for help!

• How to pass a value between Silverlight pages for WP7?

  - by Sebastian Gray

  I've got a MainPage.xaml page a Detail.xaml page. I've passed variables to the Detail.xaml from MainPage.xaml by using a static variable and referencing it in Detail.xaml (the detail page is acting like a dialog). However once I've updated the content of another object, I want to call a method in MainPage.xaml to refresh the content of that page using the updated object from the Detail.xaml page. I assume I am not using the correct paradigm for this and should probably be using MVVM or something but I'm not familiar with the implementation and was hoping there was a simple way to do this?

• How to interrupt a waiting C++0x thread?

  - by doublep

  I'm considering to use C++0x threads in my application instead of Boost threads. However, I'm not sure how to reimplement what I have with standard C++0x threads since they don't seem to have an interrupt() method. My current setup is: a master thread that manages work; several worker threads that carry out master's commands. Workers call wait() on at least two different condition variables. Master has a "timed out" state: in this case it tells all workers to stop and give whatever result they got by then. With Boost threads master just uses interrupt_all() on a thread group, which causes workers to stop waiting. In case they are not waiting at the moment, master also sets a bool flag which workers check periodically. However, in C++0x std::thread I don't see any replacement for interrupt(). Do I miss something? If not, how can I implement the above scheme so that workers cannot just sleep forever?

• Factory vs instance constructors

  - by Neil N

  I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

• How to make IIS wait for WCF service gets ready?

  - by Kamarey

  I have a WCF service hosted in IIS 7. It takes some minutes until this service finish to load its data and ready for external calls. Data loads in internal thread. The problem is that from IIS point the service is ready just after it was activated (by some call), and it process a request without waiting for data to be loaded. Is it possible to tell IIS that the service is still loading and make this service unavailable for requests? No problem if such request will throw an exception.

• java: communication between threads

  - by TRU7H

  I'm making a little java game in which I would have two threads (well as the FIRST step towards multithreading...), one for the logic and one for the drawing. So my question is: How can I make those two communicating which each other? Requirements: accessing variables and object from a another thread syncing them so they each complete a same number of "loops" in the same time. (the logic calculates and then the another one draws the results and the loop begins again...) So how is this achievable in java? Thanks in advance!

• Regarding Shell variable

  - by arav

  I need to call another shell script testarg.sh within my main script. This script testarg.sh has arguments ARG1 ,ARG2, ARG3. I need to call up the below way ./testarg.sh -ARG1 -ARG2 -ARG3 ARG1 and ARG3 argument Variables are mandatory ones. If its not passed to the main script then i quit. ARG2 is an optional one. If the ARG2 variable is not set with value or it's not defined then i need not pass it from main script.So i need to call up the below way ./testarg.sh -ARG1 -ARG3 If the value exist for the ARG2 Varibale then i need to call the below way ./testarg.sh -ARG1 -ARG2 -ARG3 Do i need to have a if else statement for checking the ARG2 variable is empty or null. Is there any other way to do it.

• Determine if javascript has completed.

  - by Duracell

  My question is somewhat similar to this one. We want to know if there's a way to determine if all javascript has completed (so no javascript is running). We have a lot of stuff that runs on a timeout after the page's onload event, so even after the page is loading, stuff could be happening for a few seconds. For a whole bunch of reasons, mostly relating to requirements from management, we need to know when all of these scripts have finished running. There's an arbitrary number of them so a general solution would be great.

• JavaScript: How to download JS asynchronously?

  - by Teddyk

  On my web site, I'm trying to accomplishes the fastest page load as possible. I've noticed that it appears my JavaScript are not loading asynchronously. Picture linked below. How my web site works is that it needs to load two external JavaScript files: Google Maps v3 JavaScript, and JQuery JavaScript Once it loads these external javascript files, it then, and only then, can dynamically render the page. The reason why my page can't load until both Google Maps and JQuery are loaded is that - my page, based on the geolocation (using Gmaps) of the user will then display the page based on where they are located (e.g. New York, San Francisco, etc). Meaning, two people in different cities viewing my site will see different frontpages. Question: How can I get my JavaScript files to download asynchronously so that my overall page load time is quicker?

• Injecting a dependancy into a base class

  - by Jamie Dixon

  Hey everyone, I'm on a roll today with questions. I'm starting out with Dependency Injection and am having some trouble injecting a dependency into a base class. I have a BaseController controller which my other controllers inherit from. Inside of this base controller I do a number of checks such as determining if the user has the right privileges to view the current page, checking for the existence of some session variables etc. I have a dependency inside of this base controller that I'd like to inject using Ninject however when I set this up as I would for my other dependencies I'm told by the compiler that: Error 1 'MyProject.Controllers.BaseController' does not contain a constructor that takes 0 argument This makes sense but I'm just not sure how to inject this dependency. Should I be using this pattern of using a base controller at all or should I be doing this in a more efficient/correct way?

• (VB or C#) Run app in system tray and listen to keyboard input even when the app is not in focus

  - by Avinash Sonee

  I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key (http://msdn.microsoft.com/en-us/library/ms646309(VS.85).aspx) but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application. I want to build one but need some help. Thanks!

• Adding mouse events to dynamically loaded SWF

  - by Josamoto

  I am loading an external SWF using the Loader class, and adding it to the stage with addChild. When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires. Is there a specific way to add listeners to externally loaded movie clips? My code looks somewhat like this: var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target); The target shows up on the display, but the CLICK event is completely ignored.

• How to download files directly to disk on the iPhone os?

  - by favo

  Hi, I would like to download files directly from an URL to the disk using objective-c on the iPhone os. Currently I am using NSURLConnection to send a synchronousRequest, writing the returned NSData into a file. How can I change the download handling (still having the request beeing synchronous, it is already in a background thread) to write the data directly to disk, not using memory variables to store the complete content (only small parts)? A sample code would be appreciated. Thank you all in advance for your responses!
