• iPhone In-App Purchase Store Kit error -1003 "Cannot connect to iTunes Store"

  - by Rei

  Hi all- I've been working on adding in-app purchases and was able to create and test in-app purchases using Store Kit (yay!). During testing, I exercised my app in a way which caused the app to crash mid purchase (so I guess the normal cycle of receiving paymentQueue:updatedTransactions and calling finishTransaction was interrupted). Now I am unable to successfully complete any transactions and instead am getting only transactions with transactionState SKPaymentTransactionStateFailed when paymentQueue:updatedTransactions is called. The transaction.error.code is -1003 and the transaction.error.localizedDescription is "Cannot connect to iTunes Store"! I have tried removing all products from iTunesConnect, and rebuilt them using different identifiers but that did not help. I have also tried using the App Store app to really connect to the real App Store and download some apps so I do have connectivity. Finally, I have visited the Settings:Store app to make sure I am signed out of my normal app store account. Any ideas? -Rei

• Component properties working at designtime but not runtime

  - by delphi-rulez-2010

  I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

• Trouble getting Android emulator to run in eclipse

  - by Sharonix

  Hi there, I'm new to Android and Eclipse. I'm Trying to run the SDK Samples on the Emulator in Eclipse 3.5 Most of the time the AVD Manager hangs when I try to create a new AVD.

Try re-creating it. I'm running the latest version of the SDK on Win7 32 bit. Any Ideas?

• Find package name for Android apps to use Intent to launch Market app from web

  - by eom

  I'm creating a mobile website that will include a page from which people can download relevant apps that we recommend. I've found instructions for creating the links to launch the Market but this assumes that you are the developer of the app in question and know the exact package name. Is there any way to get the package name, other than just contacting the developers and asking? Also, it turns out that those instructions don't really work for creating web hyperlinks. They only give you a URI to reference in a string of Java code in another Android app. Our site is in Drupal, so Java is not going to work. For the iPhone, I found easy instructions for getting the URL/link style I need from the iTunes store, so I'm looking for info like that.

• Memory footprint of a parsed XML file in Classic ASP?

  - by Pete Duncanson

  Anyone know of a way to find out the amount of memory/size of a XMLDocument once it has parsed a XML file? I've been doing "beer mat" calculations so far but have been asked to come up with some more legit numbers through monitoring some how. I need to create about 1500 XML files (via FreeThreadedXMl-DOM object), which verge between 3-9K in size and store them in Application vars but our SysAdmin is worried about us gobbling up too much memory. Other than the crude method of booting up a fresh IIS instance and then loading everything in and monitoring before and after memory usage in Task Manager I can't think of a way of doing it with a bit more accuracy.

• Unkillable console windows

  - by rep_movsd

  I'm developing an OpenGL based 2d simulation with GLUT under Visual C++ 2008, sometimes when I have an assert() or unhandled exception and break into the debugger, the GLUT display window closes, but the console window remains open.They just cant be killed!!! They do not show up with Task manager, Process Explorer or any other tool, I cannot find the window handle using the Spy++ tool either. Worst thing is they prevent my system (Windows XP) from shutting down, I have to manually poweroff (and of course I have to run chkdsk on my drives and invariably it finds and fixes minor errors after bad shutdowns) Has anyone come across such an issue?

• Migrate SVN repository from Google code to another repository server (keeping history)

  - by Marco Demaio

  I read some question/answers here about how to do it using svnadmin/dump etc. Actually I did not understand properly what I'm supposed to do. http://stackoverflow.com/questions/939963/how-to-migrate-svn-to-another-repository I think I have to do some sort of dump from the Google code repository using svnadmin, but where do I get this svnadmin? I use TortoiseSVN 1.6.3 on WXP and there is no svnadmin.exe command in all my C folder, where am I supposed to download these applications? Thanks!

• JAXB Locator - missing dependency?

  - by Wouter Lievens

  On my current project we generate JAXB beans from an XSD file. We need line number information on the beans (beyond XSD validation errors!) so I used the -Xlocator option specified here: http://java.sun.com/webservices/docs/1.6/jaxb/xjc.html However, I'm missing the Locator class. The jar file referenced to on that six-year old page can't be found anywhere, as I don't see a download for JWSDP on any site at all. Is XJC dead? Should I be using something else?

• Creating an installer with WPF forms, packaged files and custom setup actions in C#

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• Managing string resources in a Java application - singleton?

  - by Joe Attardi

  I seek a solution to the age-old problem of managing string resources. My current implementation seems to work well, but it depends on using singletons, and I know how often singletons can be maligned. The resource manager class has a singleton instance that handles lookups in the ResourceBundle, and you use it like so: MessageResources mr = MessageResources.getMessageResources(); // returns singleton instance ... JLabel helloLabel = new JLabel(mr.getString("label.hello")); Is this an appropriate use of a singleton? Is there some better, more universally used approach that I'm not aware of? I understand that this is probably a bit subjective, but any feedback I can get would be appreciated. I'd rather find out early on that I'm doing it wrong than later on in the process. Thanks!

• Log4cxx sample program and steps to compile

  - by Jake

  Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

• If you can't do a Support Role, does this mean you should not be in development?

  - by Alex

  Hi, I've been shifted around roles a lot, and have been put in a support role which seems to deal out a lot of rubbish due to poor business management. Anyway, my line manager says that he's not sure he would recommend me for a developer role as they regard support as a poor technical role. What I resent is the fact that not all the information is available to us about what we're supporting and I miss coding. This thing I'm supporting has been regarded as a disaster when it went in and is still highly unstable. The thing is...does he have a point about Support roles being under developers, or are they completely two different kettle of fish?

• Java Polymorphism - Selecting correct method based on subtype

  - by Marty Pitt

  Hi Given the following Class and Service layer signatures: public class PersonActionRequest { PersonVO person // ... other fields } public class MyServiceLayerClass { public void requestAction(PersonActionRequest request) { PersonVO abstractPerson = request.getPerson(); // call appropriate executeAction method based on subclass of PersonVO } private void executeAction(PersonVO person) {} private void executeAction(EmployeeVO employee) {} private void executeAction(ManagerVO manager) {} private void executeAction(UnicornWranglerVO unicornWrangler) {} } As discussed here, java will select the best method based on type info at compile time. (Ie., it will always select executeAction(PersonVO person) ). What's the most appropriate way to select the correct method? The internet tells me that using instanceof gets me slapped. However, I don't see the appropraite way to select the method without explictly casting abstractPerson to one of the other concrete types. Thanks Marty

• Silverlight: Binding to static value

  - by queen3

  I need TextBlock.Text to be retrieved from translation manager, something like <TextBlock Text="{Binding TranslateManager.Translate('word')}" /> I don't want to set DataSource for all text blocks. The only way I found how to do this is to bind to "static" class and use converter: <TextBlock Text="{Binding Value, Source={StaticResource Translation}, Converter={StaticResource Translation}, ConverterParameter=NewProject}" /> And these helper class public class TranslationManager : IValueConverter { public static string Translate(string word) { return translate(word); } // this is dummy for fake static binding public string Value { get; set; } public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { var name = parameter as string; return TranslationManager.Translate(name, name); } } But, is there a better - shorter - way?

• What next in the career map for a Lead QA Engineer

  - by chandran

  I am a Lead QA Engineer in a Software company and at a stage in my career wherein i need to plan my next move. Option 1: The very obvious move would be to stay as a QA Lead and eventually become a QA Manager. But i don't see very good prospects/future after that. Or am i wrong? Option 2: I love programming/coding, though i haven't spent a whole lot of time on that. So a direct move to becoming a Software Developer is not possible. Will moving to Test Automation eventually lead me to development. Even so, am i looking at step-down in pay and career-level. Option 3: Moving to Product Management. Is this even possible and if so what would be the best approach. Appreciate all your responses in advance. Thanks.

• Caching web page data, Database or File

  - by Mahdi

  I am creating an RSS reader application that requests the RSS from my server. I mean, the RSS is first downloaded to my server, then application downloads it from my server. I want to create RSS cache for this. And for example, each RSS would be refreshed every 1 minute. So, If 10 users request RSS of example.com in 1 minute, my server will download it only for the first time, and in other 9 requests, RSS will be loaded from cache. My question is, Should I use a Database (MSSQL) for this purpose? or I should use files? I have no limit in Database size nor in file size... EDIT: I'm using ASP.NET for the server.

• How do I use a shared library (in this case JsonCpp) in my C++ program on Linux?

  - by Not Joe Bloggs

  I'm a new-ish C++ programmer, and I'm doing my first program on my own using C++. I decided I would like to use JSON to store some of the data I'm going to be using, and I've found a library to handle JSON, JsonCpp. I've installed the library using my Linux system's package manager, and in my C++ code, I've used in my source code file #include <json> and compiled it using g++ and it's -ljson and -L/usr/lib options (libjson.so is located in /usr/lib). However, the first usage of Json::Value, an object provided by the library, gives a compilation error of "Json has not declared". I'm sure my mistake is something simple, so could someone explain what I'm doing wrong? None of the books I had mention how to use shared libraries, so I've had to google to find this much.

• Key logging in .NET

  - by Moshe

  Is it possible to write a key logger in Visual Basic.NET? Is this the right language to be using? So far, I've gotten a console app to read input and append to a file. 1)How can I make a .NET program "catch" all keyboard input? 2)How do I make a process not show up in Task Manager? This is not for a virus, but rather a parental control program for a specific clientele. No malicious intent here.

• C++: How to build an events / messaging system without void pointers?

  - by Jarx

  I'd like to have a dynamic messaging system in my C++ project, one where there is a fixed list of existing events, events can be triggered anywhere during runtime, and where you can subscribe callback functions to certain events. There should be an option for arguments passed around in those events. For example, one event might not need any arguments (EVENT_EXIT), and some may need multiple ones (EVENT_PLAYER_CHAT: Player object pointer, String with message) The first option for making this possible is allowing to pass a void pointer as argument to the event manager when triggering an event, and receiving it in the callback function. Although: I was told that void pointers are unsafe and I shouldn't use them. How can I keep (semi) dynamic argument types and counts for my events whilst not using void pointers?

• HTML Chrome Audit Specify Image Dimensions

  - by AKRamkumar

  I just started using the chrome developer tools for some basic html websites and I used the audit tool. I had two identical images, one with the height and width attribute, and one without. On the Resources section, both the latency and the download time were identical. However, the Audit showed Specify image dimensions (1) A width and height should be specified for all images in order to speed up page display. Does this actually help? And are there any other ways to speed up page time? This is only a splash page for the website I am building and as such it is only html, no css or javascript or anything. I have already compressed the images but I want to speed up load time even more. Is there a way?

Does anybody of you know such community's?

• Multithreading in Lua

  - by RCIX

  I was having a discussion with my friend the other day. I was saying how that, in pure Lua, you couldn't build a preemptive multitasking system. He claims you can, because of the following reason: Both C and Lua have no inbuilt threading libraries [OP's note: well, Lua technically does, but AFAIK it's not useful for our purposes]. Windows, which is written in mostly C(++) has pre-emptive multitasking, which they built from scratch. Therefore, you should be able to do the same in Lua. The big problem i see with that is that the main way preemptive multitasking works (to my knowledge) is that it generates regular interrupts which the manager uses to get control and determine what code it should be working on next. I also don't think Lua has any facility that can do that. My question is: is it possible to write a pure-Lua library that allows people to have pre-emptive multitasking?

  Well, i was looking forward to modify the bit rate of a mp3 file in java. I want to downsample(change its bit rate) the mp3 file from 256/384 kbps to say 64/128 kbps.. (I guess this is the only way one can achieve mp3 compression..or is there any other way.?) I searched for LameOnJ but that website is temperoraly down and so im not able to get the license file which we need to download in every 2 days. Is this possible using JMF..? What are the other option i have..? Regards, Veenit Shah
