• Iphone does not recognize reneweed ad hoc provising profile

  - by Amnon Dekel

  I installed a new version of an app we are developing, and also a new ad hoc provisioning profile (the old one had expired). I removed the app and profile from the phone and from itunes. Added the new profile and app to itunes and synched. All seemed well- the new profile was on the phone and the new app too. But when trying to launch the app, I get an alert: "the application cannot be opened because the provisioning profile has expired". I removed and reinstalled. I rebooted the phone. Nothing helped. Any ideas? Thanks

• How can I split the suckerfish Menu into two pieces so that I can put it in two frame?

  - by Kai

  I found a tutorial for developing multi-level drop down menu here.Its demo can be checked at www.kriesi.at/wp-content/extra_data/suckerfish_tutorial/step4.html#. I would like to enhance it to support cross-frames . It means, the horizontal part of the whole menu (html,css,javascript etc..in demo page) will exist in the upper frame and the rest will be put in the lower frame. Edit: There will be only one menu item in the horizontal part. It will be still ok if I can click that menu_item rather than mouse-hovering to show the lower part of the menu . Any idea will be appreciated. Thanks.

• How painful is a django project upload to a live (staging) site?

  - by Ignacio

  Hi, I've getting quite fast with a small django project of mine, which I'm developing locally, of course. But, as I had never worked with django before, I'm not aware of what it implies to upload it and test it on a production server. And I'm quite curious, since I'm very eager to test an early release live. I know there is this document, which I think it'll be really helpful: http://djangobook.com/en/2.0/chapter12/ But, are there any details I should take into account before, during and after the deployment? Any advice or best practices? Thanks.

• Pre loaded database on iPhone?

  - by Julian

  Hi, I have recently developed an app using core data as the storage db. The app allowed the user to read and write to the db. I am now developing a new app which the user doesnt need to write anything to the db, instead the app just needs to read the data. The data has relationships etc so cannot just use a plist or something similar. My question is should I use core data for such a requirement and if so how would i go about entering the data and then releasing the app. Would I have to code the data entry which would populate the db then remove all this code (as I dont want the database to repopulate every time the user opens the app)?? Is there a way to create a core data model using sql commands as with sqlite ie insert into..... etc? Any ideas/thoughts would be very helpful. Many thanks Jules

• Microsoft Visual Studio License

  - by Germstorm

  I developed a small winforms application for myself in Microsoft Visual Studio 2008 Professional Edition at my workplace, the Visual Studio is licensed to the firm I work at. If I want to sell that application, what are my license options? EDIT: The issue here is not my relationship with my employer (the code was written after hours, we have an understanding) but my relationship with Microsoft. Ex. if I continue developing in Visual Studio Express can I keep my old code? Is there a way to verify if some assemblies were written using a Visual Studio Professional?

• Deploying BlackBerry Applications Across Environments

  - by sethxian

  Has anyone come up with a good solution for deploying BlackBerry applications across different environments? My example is storing URLs and Authentication information in code. In most cases, a developer is going to have a different set of URL's to test against when developing the application vs what the end user is going to hit. The idea is when I go to build for production, I have something swap out the environment settings for the target environment vs manually replacing environment specific code each time. I am currently using eclipse. The only thought I've come up with so far would be to use a resource with encrypted values and have that swap when I run my build. Any ideas?

• Python: How to run unittest.main() for all source files in a subdirectory?

  - by Pete

  I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

• Screen orientation change forces data re-entry

  - by Timbermar

  I'm developing a simple app, only a handful of activities and nothing to complicated. The issue I'm having is that in a few of my activities I have EditText widgets, and when the screen is rotated, these widgets loose their values. They still visually, that is, on the handset screen, report their values from before the rotation, but to the code report their default values. An example, I have an activity with an EditText, I enter a number, 15, the calculator starts calculating, displays a result. If at this point I rotate to a different orientation, as expected the activity dies, reloads, shows the new orientation, my value of 15 is still in the EditText, however the calculator (the code) calculates as if it was 0, which is the initial value. I have not tried changing the initial value to see if it is really pulling from the default value, or just setting itself to 0 when I cast it as an int. If I didn't explain this well enough, let me know, I can add source code if I need to. Thanks.

• Utilizing multiple python projects

  - by Marcin Cylke

  Hi I have a python app, that I'm developing. There is a need to use another library, that resides in different directory. The file layout looks like this: dir X has two project dirs: current-project xLibrary I'd like to use xLibrary in currentProject. I've been trying writting code as if all the sources resided in the same directory and calling my projects main script with: PYTHONPATH=.:../xLibrary ./current-project.py but this does not work. I'd like to use its code base without installing the library globaly or copying it to my project's directory. Is it possible? Or if not, how should I deal with this problem.

• What are the disadvantages of targeting the JVM instead of x86?

  - by Pindatjuh

  I'm developing a new language. My initial target was to compile to native x86 for the Windows platform, but now I am in doubt. I've seen some new languages target the JVM (most notable Scala and Clojure). Ofcourse it's not possible to port every language easily to the JVM; to do so may lead to small changes to the language and it's design. After posing this question, I even doubted more about this decision. I now know some "pro" JVM arguments. The original question was: is targetting the JVM a good idea, when creating a compiler for a new language? Updated the question: What are the disadvantages of targeting the JVM instead of x86 on Windows?

• Is a commercial licensing tool better than a home grown solution for licensing a software product.

  - by Kalpak

  Hi, We are developing a product in C#.Net. We would definately not like our product to be copied easily across machines (in short pirated). For that purpose can anybody suggest using a 3rd party tool or a home grown solution. What are the pros and cons of each. One negative about home grown solution is that the cost involved in creating one from scratch. Can somebody comment on the technology to be used for licensing as .Net can be decompiled.

• Is it possible to configure Apache to host both an ASP.NET Web Service and a PHP Web site?

  - by Eduardo León

  Noob question (because I'm a noob when it comes to Web development). I'm not sure whether I should ask it here or at ServerFault. I am developing an ASP.NET Web Service and a PHP Web site consuming the Web Service. They are meant to be run on different machines. However, only for development purposes, I need to run both on my machine. I cannot use virtual machines. I would like to know if it is possible to configure IIS Apache to host both my Web Service and my Web site? Or, do I need to host the PHP site using Apache? I am using IIS 7.5 Apache HTTP Server 2.2 (NOTE: I have nothing against Apache. In fact, so far I like it more than IIS, however, I would rather not have two Web server applications installed in the same machine.) PHP 5.3.4 .NET Framework 2.0 3.0 or 3.5 (whichever comes with Visual Studio 2008) mod_aspdotnet for Apache 2.2

• Is the "message" of an exception culturally independent?

  - by Ray Hayes

  In an application I'm developing, I have the need to handle a socket-timeout differently from a general socket exception. The problem is that many different issues result in a SocketException and I need to know what the cause was. There is no inner exception reported, so the only information I have to work with is the message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" This question has a general and specific part: is it acceptable to write conditional logic based upon the textual representation of an exception? Is there a way to avoid needing exception handling? Example code below... try { IPEndPoint endPoint = null; client.Client.ReceiveTimeout = 1000; bytes = client.Receive(ref endPoint); } catch( SocketException se ) { if ( se.Message.Contains("did not properly respond after a period of time") ) { // Handle timeout differently.. } }

• How can a class's memory-allocated address be determined from within the contructor?

  - by Jim Fell

  Is it possible to get the memory-allocated address of a newly instantiated class from within that class's constructor during execution of said constructor? I am developing a linked list wherein multiple classes have multiple pointers to like classes. Each time a new class instantiates, it needs to check its parent's list to make sure it is included. If I try to do something like this: MyClass() // contructor { extern MyClass * pParent; for ( int i = 0; i < max; i++ ) { pParent->rels[i] == &MyClass; // error } } I get this error: error C2275: 'namespace::MyClass' : illegal use of this type as an expression Any thoughts or suggestions would be appreciated. Thanks.

• Field contains foreign IDs for different tables

  - by Rich

  I am developing a php/mysql driven facebook game. I am stuck on an element the table design. When a user completes a task I want to trigger any number of events. I was thinking of something like so: tbl_events *event_id - serogate primary ID *task_id - foreign ID of the task just completed *event_type - what type of event e.g is it a facebook stream publish or a message to the user or does it unlock a new element of the game? *event_param - this is where it gets tricky... the event parameter is a problem for two reasons, 1) it will contain different foreign ids... dependent on the event_type and thus it will not be possible to join to x table. Meaning I would have to call two queries. 2) Most events require a single id or text, however some events require multiple parameters - like the facebook stream publish.

• Loading HTML5 video on iPad via onclick event tied to a div

  - by joncys

  I'm developing an HTML5 application (a game), that automatically preloads 5 video files. I'm able to do so correctly on Safari for PC, so there are no overlooked problems with file formats, codecs or such. The load fails on an iPad. As an official guide for video on iOS puts it: This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not. Does this mean, that I have no means to initiate the loading of video after a user initiated action, if that action hasn't been tied to a video element (user clicked on a regular div — I request loading and displaying of a video, compared to the user actually clicking on a video element to load and play that particular element)? Thanks for your help!

• C++ Word-Number to int

  - by Andrew

  I'm developing a program that makes basic calculations using words instead of numbers. E.g. five + two would output seven. The program becomes more complex, taking input such as two_hundred_one + five_thousand_six (201 + 5006) Through operator overloading methods, I split each number and assign it to it's own array index. two would be [0], hundred is [1], and one is [2]. Then the array recycles for 5006. My problem is, to perform the actual calculation, I need to convert the words stored in the array to actual integers. I have const string arrays such as this as a library of the words: const string units[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; const string teens[] = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; const string tens[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; If my 'token' array has stored in it two hundred one in index 0, 1, and 2, I'm not sure what the best way to convert these to ints would involve.

• How To Refactor If-else Code Segment?

  - by LostInLib

  I'm developing win8(metro style) application with Html5-js-jquery. I have this code segment; GetBoutiqueDetail: function (boutiqueId, options) { if (IsUserLogin()) { //different job A } else { ShowLoginPanel(undefined); } }, GetProductDetail: function (boutiqueId, productId, options) { if (IsUserLogin()) { //different job B } else { ShowLoginPanel(undefined); } }, AddBasket: function (productId, productVariantId, quantity, options) { if (IsUserLogin()) { //different job C } else { ShowLoginPanel(undefined); } },.... .And ~20 functions should check if user login or not. I should call functions like similar to "Library.GetBoutiqueDetail();" So my question is simple, how can I refactor that code to remove these if-else sections ?

• Combining packages from different projects into a single project in eclipse

  - by primal

  Hi, As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools - Fix Project Properties. But nothing changed. Any pointers on what I am doing wrong much be appreciated.

• Ajax twice + facbook login/logout

  - by Devenv

  Hi, I have a very specific problem. The site I'm developing loads the FB connect button by ajax (it loads the box that includes FBC button). And when user logs in it loads instead of it the box with FB logout link. The problem is that FB requires to call FB.init() at the end of the body (when all the FB stuff is already on the page) and you can't do it twice as the second time is ignored. So what happens is - I do FB.init() inside the login box and FBC button works perfectly, but the logout link doesn't as FB.init() doesn't work there. The only solution I came up with is to place the login and logout buttons outside of ajax boxes and show them in the right places after ajax boxes are loaded. I'm pretty much sure this will work but I don't like the solution (which looks more like hack).

• C# - Realtime console output redirection

  - by Levo

  I'm developing a C# application and I need to start an external console program to perform some tasks (extract files). What I need to do is to redirect the output of the console program. Code like this one does not work, because it raises events only when a new line is writen in the console program, but the one I use "updates" what's shown in the console window, without writting any new lines. How can I raise an event every time the text in the console is updated? Or just get the output of the console program every X seconds? Thanks in advance!
