• How to configure a OCUnit test bundle for a framework?

  - by GuidoMB

  I've been developing a Mac OS X framework and I want to use OCUnit in my XCode 3.2.1 project. I've followed several tutorials on how to configure a OCUnit test bundle. The problem is that when I create a test case that uses a function that is defined in one of the framework's sources, I get a building error telling me that the symbol is not found. I made the test bundle dependent of my project's target as the tutorial said, but that doesn't seem to be problem. First I thought that I could solve this problem by dragging the framework's source files into the compile sources section within the Test bundle target, but then all the symbols referenced from that source file started to show up in the build errors, so that seems to not be a good solution/idea. How can I configure my unit test bundle so it builds properly?

• 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

• 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.

• I can't display my pages on ASP.NET

  - by iva123

  Hi, I'm developing a web site with asp.net on localhost, I'm beginner. I wrote a login page and it works well. However when I click a link, the server can't load the page and gives this error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Any idea?

• Application.Idle causes high CPU usage

  - by Neal

  Hello, I use the Application.Idle event to handle toolbar status (enable/disable) etc. quite extensively. As I'm beta testing Norton AntiVirus 2011, it brought to my attention that my app that I'm developing triggered a high CPU usage warning on at least one CPU. Sure enough, I opened the task manager and watched one of the four CPU's (quad core system) go to near 100%. I thought Application.Idle was the way to handle things when the application wasn't performing CPU tasks. Why is Application.Idle spiking the CPU? Here is how I attach to the event: AddHandler Application.Idle, AddressOf OnAppIdle Been using Application.Idle for a long time, never knew it would have this issue. Using VS 2010 .NET 4 Thank you.

  - by VansFannel

  I'm developing an iOS application with latest Xcode 4.5.2. I have the following folder structure: /.../SourceCode/MyProjectFolder/projectName.xcodeproject /.../SourceCode/MyProjectFolder/projectName/ /.../SourceCode/MyProjectFolder/projectName/xxx.m /.../SourceCode/MyProjectFolder/projectName/xxx.h /.../SourceCode/MyProjectFolder/projectName/PVRT/ /.../SourceCode/MyProjectFolder/projectName/PVRT/header1.h /.../SourceCode/MyProjectFolder/projectName/PVRT/OtherFolder/header2.h If in my header files I add this: #include "header1.h" I get a "header1.h" not found error. But, if I add: #include "PVRT/header1.h" I get a "header2.h" not found. On project settings I have add the following path: ${SOURCE_ROOT}/projectName/PVRT But I'm getting the same error. How can I fix this?

• Need Language/Career Path Advice

  - by Cain

  I am interested in getting a few Microsoft Certs and I am currently facing the option for .NET Framework app development language. My choices are C++, C#, and Visual Basic. I have some experience with Java and Visual Basic .NET but I honestly would like to know what the best would be for developing stand-alone applications in a workstation (local) environment. This is for my career and honestly, 90% of the developers are all experienced in the above three languages and I wanted to improve my chances of staying employed by learning/certifying myself on my own time.

• Guaranteeing the onmouseout event to fire

  - by n3rd

  Hello everybody, I'm currently developing a web application and have run into a little problem. I'm using ExtJS, but I believe this to be a general JS question. When the cursor enters an HTML element, the onmouseover event is fired, when the cursor leaves that element, onmouseout is triggered. So far, so good. Unfortunately, it seems one can't fully rely on this behaviour. Very quick mouse movements can cause the event not to fire (as does repositioning the cursor with a pen tablet, for example). What are the best practices to handle these issues? Do I need to monitor all onmousemove events and manually keep track of where the cursor was last and fire the appropriate onmouseout event myself?

• is XULRUNNER suitable as a replacement for other C++ desktop applications frameworks such as QT?

  - by Gabriel Cuvillier

  XulRunner/Gecko seems to be really interesting for developing gui-intensive applications (by using widely used technologies such as HTML / CSS / SVG / XUL / Javascript). But the underlaying C++ APIS (XPCOM, NECKO, ...) looks so old and complex. Moreover the general lack of documentation/developper tools is really frightening. On the other hand, QT have a quite nice platform, and is well documented and supported. The UI part is really "traditional" though. What are your experiences with XULRUNNER, specially compared to other C++ desktop applications frameworks such as QT/GTK/MFC...? What is missing? What is awesome? Side question: If I wanted to migrate an existing MFC app to a cross platform C++ desktop application framework, would it be wise to use XULRUNNER instead of QT or GTK?

• Is it a good idea to close and open hibernate sessions frequently?

  - by Gaurav

  Hi, I'm developing an application which requires that state of entities be read from a database at frequent intervals or triggers. However, once hibernate reads the state, it doesn't re-read it unless I explicitly close the session and read the entity in a new session. Is it a good idea to open a session everytime I want to read the entity and then close it afterwards? How much of an overhead does this put on the application and the database (we use a c3p0 connection pool also)? Will it be enough to simply evict the entity from the session before reading it again?

• Partioning the Table into .net - Creating columner database.

  - by Omky

  Hello Geeks, I am developing some tool for BI. There are terms like Fact, Dimensions and Measures. My application will connect to the normal database and read the data from that table. Now, I want to convert all this data into columnar database. That is all the columns from this table will be transfer into 3 tables each. Consider below table:- ID Product 1 XYZ 2 ABC 3 ABC Now, I want to convert the Product column i.e. dimension into 3 tables. dim_product_table:- ID Product 1 XYZ 2 ABC dim_product_fmk(fact map by key):- Where we will store key-value pair of Key Row 1 1 1 2 2 3 dim_product_fmr(fact map by row):- The above table will be reversed. Row Key 1 1 2 1 3 2 The another requirement is all above table should be generated dynamically and I should be able to JOIN all those. Can anybody help me? Thanks in advance.

• How can I use Three20 to create a dynamic TTThumbsViewController that feeds from a website directory?

  - by Cory Robbins

  Hello, I'm pretty new to the iPhone developing scene, and I am designing an app for a high school band program. Part of the app needs to be an image gallery that retrieves photos from a directory on the band's website and lists them in the thumbnail view. I can't figure out how to create a thumsview that isn't directly linked to specific pictures. I currently have this setup to work with a UIWebView that points to a PHP photo album designed to look like the iPhone Photo Album. This method works, but it is not ideal, and the navigation is obviously a bit less than what would be expected. Is Three20 the right tool for this job? If not, what should I be using? Thanks!

• How to make CSS/HTML prototyping faster for engineers without strong CSS skills?

  - by rdeshpande

  I've been developing Ruby on Rails applications for some time, and have often found help to develop generate the templates of HTML with accompanying CSS. However, I'd like to make an attempt at doing this myself. Initial experiments leave me feeling like my process is really slow. I'm writing all my Rails code in VIM, which, with accompanying aliases to run the test suite, is pretty fast for me. However, the back-and-forth between browser/VIM to see new changes seems cumbersome - I'm guessing finding an editor with an embedded browser that constantly sees new changes is ideal for this (any suggestions?) So far I've experimented with Blueprint, which at the onset seems like it will save me a ton of time. However, what other tools have helped you do the PSD-HTML/CSS conversion as fast as you can?

• How do I handle user authorization the safest way?

  - by Irro

  I'm developing a small website where I'm going to allow user to create accounts but I'm quite clueless when it comes to safety around authorizations. I have built my project in PHP with codeigniter and found a library (Tank Auth) that could handle authorization for me. It stores password in a safe way but I'm still worried about the part when the user sends their password to my server. One easy way to do it would be to send the password in a post-request but I would guess that it's quite easy to sniff such a password. Should I do something with the password on the client side before sending it to my server? And is there any good javascript libraries for this?

• Question on ExtAudioFileRead and AudioBuffer for iPhone SDK

  - by backspacer

  I'm developing an iPhone app that uses the Extended Audio File Services. I try to use ExtAudioFileRead to read the audio file, and store the data in an AudioBufferList structure. AudioBufferList is defined as: struct AudioBufferList { UInt32 mNumberBuffers; AudioBuffer mBuffers[1]; }; typedef struct AudioBufferList AudioBufferList; and AudioBuffer is defined as struct AudioBuffer { UInt32 mNumberChannels; UInt32 mDataByteSize; void* mData; }; typedef struct AudioBuffer AudioBuffer; I want to manipulate the mData but I wonder what does the void* mean. Why is it void*? How can I decide what data type is actually stored in mData?

• Forcing a method to be non-transactional in JPA (Eclipselink)

  - by rhinds

  Hi, I am developing an application using Eclipselink and as part of the app I need to be able to manipulate some of the objects which involves changing data without it being persisted to the database (i merging/changing objects for some batch generation processes). I am reluctant to change the data in the Entity objects, as there is a risk that even though i have not marked the methods as @Transactional, this method could in the future be inadvertantly called from within a transactional method and these changes could be persisted. So my question is, is there anyway to get around this? Such as force a method to always be non-transactional regardless; terminate any transactionality as soon as the method is started; etc. I know there is a .detach() method that can detach the objects from the Entity Manager, however, there are many objects and this seems like a potentially error prone fail-safe on my code.

• Android pattern for activity "flows"

  - by Otto

  I'm developing an android app that has a bunch of screens (activities) that are supposed to have "continue" and "back" buttons at the top. Can you tell me the right pattern for implementing this? I've seen some iPhone apps that have this but Android apps usually don't (I think partly because the back button is part of the phone). I found a post online about an Activity class that has "sub activities" which kind of seems like what I want to do, but I'm wondering if there's a simpler solution or pattern for creating flows like this (in which several activities are linked with continue/back buttons).

• What is the best API in any language for Audio and MIDI music application development?

  - by noneme

  What, in your opinion, is the best API to utilize in developing an application that handles both realtime MIDI and audio input and output? This would be for an application that is used in the process of making music as opposed to playing audio or MIDI files. I'm aware that this may be a subjective question, but if you know of an API that is dominantly used for these purposes, please share it. I'm agnostic about which language the API is for, and I also don't care about portability. The real concern is for an API that is well documented, well designed (e.g. thought out and intuitive to developers using it), and actively maintained. OS portability would be nice, but it is second to having an API/Language that meets the previous requirements. Please note that the emphasis is not on API's for sound synthesis or for composing music with code. It is intended for the handling of sound file and MIDI data in a real-time context.

• Removing unused selectors in a CSS stylesheet?

  - by Legend

  I've been developing a web app for a few weeks now and ended up with about a 1000 lines. I am sure not all the selectors are being used and am trying to clean it up. At the same time, I don't want to do it manually for obvious reasons. Is there a safe and an efficient way to remove unused selectors? For this, am I supposed to navigate the entire website to let it know which selectors are not being used? (I use javascript to add some selectors so these might not show up until a particular usecase is seen)

• 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.
