• "There was an internal API error." while running an app on any iPhone/iPod-touch device

  - by Martin Cowie

  I am in the process of submitting an iPhone app to the app store. While making the final touches to the app I was in the process of compiling and running the app on my iPhone when I got the message ... "There was an internal API error." The console had this to say ... 25/08/2010 10:10:54 Xcode[3556] Failed willExecute: Error Domain=com.apple.platform.iphoneos Code=0 UserInfo=0x2011adec0 "There was an internal API error." -- { NSLocalizedDescription = "There was an internal API error."; NSLocalizedFailureReason = ""; NSLocalizedRecoverySuggestion = ""; } The problem is specific to this project, others projects don't suffer the same problem. The same problem exhibits when moved to another machine, or another mobile device is swapped in. I should be most grateful for any hints or ideas on the subject ...

• What ever happened to Java and Sun?

  - by leeand00

  What happened to Java and Sun? The community surrounding them had some of my favorite tools and software to develop with. The Java platform anyway, still looked like it had some promise to it: Groovy and Grails. Why does all of this seem to be going the way of the dodo lately? (Yes, I know their stock price is dropping badly.) Is it just the economy? Or did the lack of cohesion (i.e., not settling on a framework) among the community finally lead to its demise?

• How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

  - by Kendrick Ledet

  Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

• Make a USB Device, Control It In Java

  - by yar

  I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well1. Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is there something better suited for communicating with Java? Note: I know that Arduino has something to do with Java (not sure what), but it seems like code must be written in a subset of C. How would I get moving on this topic? 1 - No laughter, please.

• Is PThread a good choice for multi-platorm C/C++ multi-threading program?

  - by RogerV

  Been doing mostly Java and smattering of .NET for last five years and haven't written any significant C or C++ during that time. So have been away from that scene for a while. If I want to write a C or C++ program today that does some multi-threading and is source code portable across Windows, Mac OS X, and Linux/Unix - is PThread a good choice? The C or C++ code won't be doing any GUI, so won't need to worry with any of that. For the Windows platform, I don't want to bring a lot of Unix baggage, though, in terms of unix emulation runtime libraries. Would prefer a PThread API for Windows that is a thin-as-possible wrapper over existing Windows threading APIs. ADDENDUM EDIT: Am leaning toward going with boost:thread - I also want to be able to use C++ try/catch exception handling too. And even though my program will be rather minimal and not particularly OOPish, I like to encapsulate using class and namespace - as opposed to C disembodied functions.

• MultiThreading question

  - by TiGer

  Hi, I am developing on Android but the question might be just as valid on any other Java platform. I have developed a multi-threaded app. Lets say I have a first class that needs to do a time-intensive task, thus this work is done in another Thread. When it's done that same Thread will return the time-intensive task result to another (3rd) class. This last class will do something and return it's result to the first-starting class. I have noticed though that the first class will be waiting the whole time, maybe because this is some kind of loop ? Also I'd like the Thread-class to stop itself, as in when it has passed it's result to the third class it should simply stop. The third class has to do it's work without being "incapsulated" in the second class (the Thread one). Anyone knows how to accomplish this ? right now the experience is that the first one seems to be waiting (hanging) till the second and the third one are done :(

• How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

  - by user239619

  I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.

• Using a database/index sequential file independently of the Unix distribution

  - by Helper Method

  What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

• Multiple Inheritance Debates II: according to Stroustrup

  - by asksuperuser

  I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here : http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance But according to Stroustrup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level. What do you think ? Why Sun and Microsoft consider developers too immature to just make the choice themselves ?

• 32/64 Bit Question

  - by user48408

  Here's my question. What is the best way to determine what bit architecture your app is running on? What I am looking to do: On a 64 bit server I want my app to read 64 bit datasources (stored in reg key Software\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources) and if its 32 bit I want to read 32 bit datasources, (i.e. Read from Software\ODBC\ODBC.INI\ODBC Data Sources). I might be missing the point, but I don't want to care what mode my app is running in. I simply want to know if the OS is 32 or 64 bit. [System.Environment.OSVersion.Platform doesn't seem to be cutting it for me. Its returning Win32NT on my local xp machine and on a win2k8 64 bit server (even when all my projects are set to target 'any cpu')]

• closing sockets on linux and windows

  - by robUK

  Hello, gcc 4.4.4 c89 Visual Studio VC++ 2008 I am writing a cross platform client server application. It will run on both linux and windows. However, I am just wondering what I have done for closing the sockets is correct. I close the file descriptor. However, if there is a problem with closing it. What is the best way to handle this. Maybe some data is still being sent or received? Many thanks for any advice, if(close(sockfd) == -1) { #if defined ( _WIN32 ) fprintf(stderr, "[ %d ] [ %s ] [ %s ] [ %d ]\n", WSAGetLastError(), strerror(errno), __func__, __LINE__); #elif( __linux__ ) fprintf(stderr, "[ %s ] [ %s ] [ %d ]\n", strerror(errno), __func__, __LINE__); #endif return CS_FAILURE; }

• how to achieve Inter-Widget communication

  - by bakore

  I was looking for a platform where widgets developed using various technologies like Java can communicate with each other. In other words When I add widgets to an interface I need them to talk to each other. For example A Click event in one widget should trigger an event in some other widget. I have been looking into the web for solutions and ways to do it, but couldnt find anything concrete. Any pointers or information on this would be great. Something like this http://blogs.sun.com/pdblog/entry/inter_widget_communication_in_cross

• record mouse movements, clicks and keyboard input with Java or C++

  - by Joe

  I want to be able to record mouse movements, clicks and keyboard input from a user. It would be great if it was a cross platform solution. I'd like to get back something like this (pseudo code): mouse moved to 500, 500 mouse double clicked mouse moved to 800, 300 mouse left clicked keyboard typed "Hello World" Does either C++ or Java have any classes that can do this? If I was using C++, I would probably working with the QT framework. Edit: I should have said this originally, but I want to record the movements and clicks outside of the applications gui, so on the desktop too.

• Is it possible to do an Ajax request for an ICS file?

  - by Kyle

  I am trying to do an Ajax request for an ICS file. Yeah, I know it sounds crazy, but I found the perfect library to parse the iCal data. Any ideas why the data comes up blank when I do this? $.ajax({ success:function(data){ alert(data); }, url:"http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=15714&cat=98&platform=osx&method=sa/Swiss32Holidays.ics" }); It makes the request fine, but the data still comes up blank.

• Call external library from PHP. What is faster: exec or extension?

  - by robusta

  Hi, I need to make calls from webpage to external library written in C++ and display the result. Platform is Linux, Apache, PHP. My current idea is to use PHP service which will call my library/program. I found that there are two possible ways to do this: 1) use PHP 'exec' function 2) write PHP extension I am curious what works more effective? Faster? Less load the server? I will probably need to do 4 calls per second, so I want to be as optimal as possible. P.S. If you are aware of some other (more effective) way of calling C++ library or program from webpage, please let me know. Thanks a lot, Robusta

• Python: get windows OS version and architecture

  - by Thorfin

  First of all, I don't think this question is a duplicate of http://stackoverflow.com/questions/2208828/detect-64bit-os-windows-in-python because imho it has not been thoroughly answered. The only approaching answer is: Use sys.getwindowsversion() or the existence of PROGRAMFILES(X86) (if 'PROGRAMFILES(X86)' in os.environ) But: Can we completely rely on the windows environment variable PROGRAMFILES(X86)? I fear that anyone can create it, even if it's not present on the system. How can we use sys.getwindowsversion() to get the architecture? Regarding sys.getwindowsversion(): The link http://docs.python.org/library/sys.html#sys.getwindowsversion leads us to http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx but I don't see anything related to the architecture (32bit/64bit). Moreover, the platform element if the returned tuple seems to be independent of the architecture. One last note, I'm using python 2.5. Thanks!

• Why did this code still work?

  - by bstullkid

  Some old code that I just came across: MLIST * new_mlist_link() { MLIST *new_link = (MLIST * ) malloc(sizeof(MLIST)); new_link->next = NULL; new_link->mapi = NULL; new_link->result = 0; } This was being called to build a linked list, however I noticed there is no statement: return new_link; Even without the return statement there, the list still got built properly. Why did this happen? EDT: Platform: Mandriva 2009 64bit Linux 2.6.24.7-server GCC 4.2.3-6mnb1

• Portable Socket programming in C/C++ possible?

  - by questions

  I am thinking of creating a multi-platform portable C++ server-client application. Is it even possible while using only standard libraries? If no, what other libraries are there? Are there any improvements in this direction in C++11x? Like for threads, now we have std::threads. To make it more clear.. I want something like boost::thread, which provides multiplatform portable multithreading, for networking. And why C++ doesn't have libraries(standard) for such basic things like networking?

• Mobile web apps - Is this the right approach?

  - by Pasta

  I need to build a cross platform mobile app (iphone, android, etc). The app is for a company like a cellular operator (Tmobile, ATT). The app needs to do the following: Show previous bills (cached so that it does not have to download everytime) Need an internet connection to download newer bills, view recent data, etc. Can I build a mobile web app to handle this? I understand that there is offline storage and iPhone has good support for web apps (full screen, good icons, offline, etc). Will a web app be the best approach to take as the app requires to be online? The app will not be used by lots of people, just customers of the website who don't want to use an existing website. We are all web developers and a mobile web app looks like the best way to approach this.

• VC++ to C# migration guidelines/approaches/Issues

  - by KSH

  Hi all, We are planning to move few of our VC++ Legacy products to C# with .NET platform.. I am in the process of collecting the relavent information before making the proposal to give optimistic and effective approach to clients. Am looking for the following details. Any general guidelines in migration of VC++ to C#.NET What are the issues that a team can face when we take up this activity Are there any existing approaches available ? I believe many might have tried but may not have detailed information, but consolidating this under this would help not only me but anyone who look for these information. Any good / valid resources available on internet? Any suggestions from Microsoft team if any Microsoft people in this group? Architecture, components design approaches, etc. Please help me in getting these information, each penny would help me to gain good understanding.. Thanks in advance to those who will share their wisdom thorough this query.

• iPhone : Primitives getters and setters

  - by Burf2000

  I feel a bit miffed at the moment, I done a few iPhone projects that use floats and ints etc and all is fine. I now using OpenGL and GLFloat[] C arrays etc and it seems unless I make methods to set / get them it crashes on the device (not the simulator). Now as these are not setup as properties (I don't think c arrays can) it kind of makes sense. However the project has been working for months without them. It seems something in the code is wiping out anything float / ints to the point that the debugger can see an assigned value but accessing it crashes the phone. As soon as I think I know something for this platform, something changes my mind lol.

• 3rd party applications API / Framework Q for PHP user site

  - by Ryan

  So we are defining out functional requirements for a user content site and would like to enable: 1) 3rd party developers to develop applications that users can use on their profile 2) Enable users to export content to other sites meaning share their photos on the net. So we were told we need to use APIs for this & it's merely changing data permissions. Is that the only thing we need? Is there a framekwrok we need to build out, or what is the process functioanlly to define out to make these happen? Platform is being built on MySQL and Cake php.

• using different string files in android

  - by boreas

  I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

• Eclipse and SVN: Missing .project file.

  - by DHC

  Hi, I'm working on a uni project with a few other people using SVN. Much to my annoyance the .project file was removed from the repository since "it contains platform specific information". However, this has obviously broken my setup in Eclipse, giving me the error: Problems occurred opening the selected resources. The project description file (.project) for '___' is missing. This file contains important information about the project. The project will not function properly until this file is restored. Any suggestions? Thank you.
