• looking for help with Flash sound to play on an iPad

  - by phm

  I hope you might be willing to help me. Years ago, when I was designing a game site, it was recommended to me to do what you pretty much suggested in your answer to a question about Flash sound: put my sound effects as Flash elements. This works great on every platform except the iPad. Do you have any idea what I should do? I'd really appreciate your help and you sound like a helpful person. Some people here can be kind of mean. I'm not a programmer by training, just self taught.

• Windows Phone 7 and C++/CLI

  - by Fabio Ceconello

  Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a similar experience? I'm not talking about code that does heavy low-level stuff - but there's a quite frequent use of templates and smart pointers.

• Package <blah> does not exist error - NetBeans 6.8 & Windows 7

  - by BenMc

  I'm using NetBeans 6.8 on Windows 7. I upgraded from WinXP and NetBeans 6.7. Now my existing java web app project is no longer able to import/find the packages I've developed - I receive a 'Package ,blah. does not exist' and yet the packages do exist, worked fine in NetBeans 6.7 and the project still compiles and runs OK. I've tried changing the Java Platform/JDK from 1.6.0_10 back to JDK 1.5.0_22 but I still receive errors package does not exist. All other 'standard' libraries and packages are able to be imported and used OK ... eg Struts, Hibernate

• android service exported attribute??

  - by doloop

  Hi, I am quite new about android platform. I want to export my service to be public used. I find something on developer doc android:exported Whether or not components of other applications can invoke the service or interact with it — "true" if they can, and "false" if not. When the value is "false", only components of the same application or applications with the same user ID can start the service or bind to it. but i dont understand it Can anyone show me a brief example of how to use it? many thx

• How do I choose a database?

  - by liamzebedee

  I need a comparison table of some sort for database varieties (MySQL, SQLite etc.). I can't find one. My use case is, I am implementing storage of objects in a distributed hash table. I need a database solution that is: Fast for sorting Simplistic (no users, preferably no additional structures like multiple tables etc.) Concurrent (if possible) Multi-platform File based (not stored in memory primarily) Centralized I will be programming in Go. As I understand, I believe I need what is called a Document Orientated Database, because I am storing objects, identified by keys. EDIT: While I am implementing a DHT, I will also be storing metadata about the objects, such as access counts etc. It would also be preferable to have TLL (time to live)

• How hard is it for a .NET programmer to learn Objective C and Cocoa?

  - by rsteckly

  Hi, I'm trying to build a dual platform application for a company of my own I'm trying to start at night. I have the .NET version done, but have not finished the UI part. I'm thinking of buying some 3rd party controls. If I buy these controls, however, they clearly will only work in my Windows version. I'm wondering if I should try to do the UI in GTK# and use Mono with CocoaSharp or just build the thing in MS technology and teach myself the Mac side? I'm just really unfamiliar with the Mac world and am wondering how much of a learning curve there might be. I've thought perhaps of rewriting my core logic in Ruby or Python. This why I could use the .NET version with .NET controls and presumably hook the same code up on the Mac. It's an educational app targeted at consumers. As such, it shouldn't require a lot of technical sophistication to install.

• feedback for programming newbies looking to build a social networking site?

  - by kgardnr

  my partner and i are launching a social learning platform - the requirements have been mapped out and are quite basic/intuitive. we are familiar with html/css, and have some very basic understanding of php, but we would love some feedback on whether we should tackle this ourselves or not. we've built websites, but in the past relied mostly on pre-fab code, i.e. wordpress, ning, etc. we've been looking specifically at ruby for developing the network, but i haven't delved into it fully yet. we're looking for some guidance and feedback - e.g. thoughts on ruby on rails? what's the learning curve? are we getting in over our heads? thanks in advance!

• Deploy java (command line) app using Netbeans / ant

  - by Haes

  I've finally managed to create a Netbeans project out of an old standalone (not Web-) Java application which consisted only out of single .java sources. Now I have basically two questions regarding Netbeans Subversion interaction and application deployment: Do you check in all the Netbeans project files into the repository, normally? If I build the project using Netbeans (or ant) I get a .jar file and some additional jar libraries. In order for the app to run properly on the server, some additional config files and directories (log/ for example) are needed. The application itself is a J2SE application (no frameworks) which runs from the command line on a Linux platform. How would you deploy and install such an application? It would also be nice if I could see what version of app is currently installed (maybe by appending the version number to the installed app path). Thanks for any tips.

• Looking for Open-Source or Licensed Personalised Greeting Card software

  - by Mr Pablo

  Before I jump in at the very deep end and try to make my own version of Moon Pig (www.moonpig.com) I would like to know what (if any) software/platforms currently exist that allow for visitors to personalise cards with text and uploaded photos and then purchase printed versions all via a single e-Commerce style platform. I have Googled till my fingers bled and I cannot find anything that matches my needs, which are: admin can provide templates (backgrounds) for the cards users can customise the card with text (font style and colour) users can upload their own photos (minor editing e.g. crop) to insert into the cards user can purchase a printed card via credit card payment Seeing as this kind of e-Commerce has been around for a while now, I would have thought there were some systems to purchase that can provide this functionality?

• Solution to combine two submit buttons.. doing two different things from the same input

  - by zac

  I am trying to figure out how to combine two different forms, both require the same input but they do two different things. One form sends a request to the ecommerce platform to get the order status, and another form takes the same order number and returns a tracking code from USP or USPS. I am looking for some guidance on how I could combine these two actions.. one is currently using the POST method and the other GET. Here is an example .. so one is This one runs a validation script to confirm the order number is valid and then returns the order info if it is the second form is sending a get request to an asp file that is generating the proper tracking numbers. Can someone please point me to how I could begin to tackle this?

• Whats are basic things you should kept in mind while writing functional tests?

  - by piemesons

  Hello, what kind of functionality should be covered in functional test? How to prioritize what are the functionality that must be covered in functional test. I can understand it depends upon on the project, whats the functionality present the project. Lets take a example of stackoverflow. Suppose we are developing a basic working model of this. What kind of functional test must be covered in this. Just brief what the key points while writing functional tests. (taking any basic functionality from this site just to understand the reference) Still its platform independent question.I am using ruby on rails developer, but keeping ruby on rails as mind will be preferable.

• Deploying a .Net App Source Control (SVN) over 32-bit AND 64-bit dev stations

  - by Mika Jacobi

  Here is the situation : Our Dev Team has heterogeneous OS systems, scattered between 32-bit and 64-bit. This is not ideal, we are actually planning to homogenize our infrastructure, but in the meantime we have to deal with it. The issue is that when a 32-bit developer checks out a 64-bit solution on SVN, he has to manually change the target platforms all over again to get it compiled (not to mention other side problems) My question is : What clean (though temporary) solution could be addressed in such situation, permitting each developer to keep his default project/platform settings while checking out and in from SVN. I guess that -at least for the first time a project/solution is checked out, a dev still has to tweak the setting manually to compile it properly. After that, according to relevant SVN filters, it is possible to ignore some settings files (which ones, by the way?) I am open to all clever and detailed suggestions. Thanks.

• Compiling Qt for Windows 98

  - by wrp

  I need to support Windows 98. The Qt documentation claims this is possible, but there are no instructions. The distributed binaries don't run on Win98 and the majority of Qt applications I have sampled also don't. For several apps that do run on 98, I have asked authors how they did it, but the common answer is that it was accidental and they don't know what factors caused it. In searching the forums for help, I found only guesses that turned out to be wrong. For example, one belief is that to compile for Win9x, you must build the tools and the apps on that platform. Yet, things I found to run were built on newer versions of Windows. What is required to build the Qt dev tools and then applications for Win98? How about cross-compiling from WinXP or Linux? Are there specific components that can't be made to run on Win98? Are there particular difficulties with dynamic or static linking for Win98 support?

• Detect if PCRE was built without the --enable-unicode-properties or --enable-utf8 configuration switches

  - by Mark Baker

  I've a PHP library that uses a number of regular expressions featuring the \P expressions for multibyte strings, e.g. ((((?:\P{M}\p{M}*)+?)|(\'[^\']*\')|(\"[^\"]*\"))!)?\$?([a-z]{1,3})\$?(\d+) While this works on most builds, I've had a few reports of the regexp returning an error. Depending on Operating platform, the error messages from PCRE are: Compilation failed: PCRE does not support \L, \l, \N, \P, \p, \U, \u, or \X at offset n or Compilation failed: support for \\P, \\p, and \\X has not been compiled at offset n I know that I can probably test a regexp at the beginning of my code that uses \P, and trap for a returned error, then use that response to set a compatibility flag and provide a degraded (non UTF-8) regexp without the \P within the main body of my code based on that compatibility flag; but I was wondering if there was any simpler way to identify whether PCRE had been built without the --enable-unicode-properties or --enable-utf8 configuration switches. PHP provides access to PCRE_VERSION constant, but that won't help identify whether \P support is enabled or not.

• Integrating Incoming Email Into a php/mysql App

  - by phirschybar

  I am looking to create an incoming email daemon switchboard that I can integrate with various remote php/mysql apps. Ideally I want to check the 'to' address to see if it is in a mysql database and if it is, have the email parsed and posted via CURL to a target destination as well as have attachments saved somewhere locally. I will likely set up a rackspace cloud server dedicated to this task (just accepting emails and posting to 3rd party APIs). However, I do not know where to start. Which server platform / distribution should I go with? Which software needs to be customized, etc?

• Better product to develop for, iPad or Android based tablet in a purely business related application

  - by Caylem

  Hey guys Just wondering what you'd suggest as the best platform for developing a business application for a tablet device. The application needs to be multitouch, have access to a maps API, a database on the device. It will not be going on sale in the app store or Androids market, it is purely for specific business task and not for the general consumer. Obviously the options seem to be iPhone OS and the iPad or Android and an Android tablet device. The form factor for the end product requires something in the region of 8 inch+ screen and enough processing power to provide a good experience for the end user. Any help would be much appreciated. Thanks

• MacPorts: Add an option to configure script

  - by Jeffrey Aylesworth

  I am trying to install libguichan without allegro support, because allegro will not build on Snow Leopard. It should be left out, the portfile has: 27 if {${os.platform} == "darwin" && (([variant_isset universal] && [string match *64* $universal_archs]) || (![variant_isset universal] && [string match *64 $build_arch]))} { 28 # allegro is not yet 64-bit compatible 29 depends_lib-delete port:allegro 30 configure.args-append --disable-allegro 31 } But when I install it, it tries to build allegro. Is there any way I can get this functionality from the command line to install it? The port: http://trac.macports.org/browser/trunk/dports/graphics/libguichan/Portfile

• Missing archetype.xml in new archetype created from project.

  - by sdoca

  Hi, I am using Maven 2.2.1. and am new to Maven. I am trying to create an archetype based on an existing project. I have been using this blog post as a guide: http://blog.inflinx.com/category/m2eclipse/ Step 7 says "The next step is to verify that the generated archetype.xml (located under srcmainresourcesMETA-INFmaven (sic)) has all the files listed and they are located in the right directories." My generated archetype does not have an archetype.xml. It does have an archetype-metadata.xml file though. There aren't any errors in the output from calling archetype:create-from-project, just a couple of warnings about using platform encoding (Cp1252). Any thoughts on why this file wasn't generated? Thanks in advance!

• Challege: merging csv files intelligently!

  - by Evenz495

  We are in the middle of changing web store platform and we need to import products' data from different sources. We currently have several different csv files from different it systems/databases because each system is missing some information. Fortunatly the product ids are the same so it's possible to relate the data using ids. We need to merge this data into one big csv file so we can import in into our new e-commerce site. My question: is there a general approach when you need to merge csv files with related data into one csv file? Are there any applications or tools that helps you out?

• In a process using lots of memory, how can I spawn a shell without a memory-hungry fork()?

  - by kdt

  On an embedded platform (with no swap partition), I have an application whose main process occupies most of the available physical memory. The problem is that I want to launch an external shell script from my application, but using fork() requires that there be enough memory for 2x my original process before the child process (which will ultimately execl itself to something much smaller) can be created. So is there any way to invoke a shell script from a C program without incurring the memory overhead of a fork()? I've considered workarounds such as having a secondary smaller process which is responsible for creating shells, or having a "watcher" script which I signal by touching a file or somesuch, but I'd much rather have something simpler.

• Windows azure deployment

  - by smoothe

  I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.

• Why does OSX document atoi/atof as not being threadsafe?

  - by Larry Gritz

  I understand that strtol and strtof are preferred to atoi/atof, since the former detect errors, and also strtol is much more flexible than atoi when it comes to non-base-10. But I'm still curious about something: 'man atoi' (or atof) on OS X (though not on Linux!) mentions that atoi/atof are not threadsafe. I frankly have a hard time imagining a possible implementation of atoi or atof that would not be threadsafe. Does anybody know why the man page says this? Are these functions actually unsafe on OS X or any other platform? And if they are, why on earth wouldn't the library just define atoi in terms of strtol, and therefore be safe?

• How do I enable code coverage in Visual Studio 2005?

  - by CandlesOfThe

  I have looked at this question; http://stackoverflow.com/questions/2872158/ and the F1 page, but that doesn't help me much. I have set the profiling on and rebuilt, but I can't find the 'Data and Diagnostics' page, or see anything which resembles a coverage data file in the project folder. What I am trying to do get an equivalent to 'gcov' on a Linux platform, get a chart of how much code is being missed by the test suite. I'm using Visual Studio 2005 Professional Edition and UnitTest++ as the test framework. Any help would be most welcome.

• Usability: Save changes using "Apply" button or after every single change?

  - by mr.b

  I am interested in hearing opinions and experiences of fellow developers on topic of designing user interface, usability AND maintainability-wise. Common approach is to allow users to tweak options and after form gets "dirty", enable "Apply" button, and user has possibility to back out by pressing cancel. This is most common approach on Windows platform (I believe MS usability guidelines say to do so as well). Another way is to apply changes after every single change has been made to options. Example, user checks some checkbox, and change is applied. User changes value of some text box, and change is applied after box looses focus, etc. You get the point. This approach is most common on Mac OSX. Regardless of my personal opinion (which is that Apple is better at usability, but software I usually write targets Windows users), what do you people think?
