• Wanting a simple overview on how to connect to a SQLite database in Cocoa/Objective-C

  - by Jesse

  Hi, everyone. I've been experimenting with Cocoa and Objective-C programming on the Mac for a few months now, and I am wanting to start developing applications that manage large amounts of data. The trouble is, I'm not really sure where to start with databases. I have a good background in Java programming with SQLite. I've read a bit about CoreData and I haven't been able to find any good resources for just manually connecting to the database. I'm looking for recommendations. Should I try CoreData, and if so, can anyone recommend a good tutorial for someone new to the language? Or, should I try to manually connect and query an SQLite database somehow, and, if so, any tutorials? Any help would be greatly appreciated! Thanks!

• Using Navigation Controller in a subview of View based Applicatin

  - by iphonix

  Some one please help me with this. I am developing an iPhone app and have stared with View Based Application. I have buttons on my root view screen to take user to other views with their own nibs and classes. On one of those views I need to display a table getting data from SQLite database and then display detail of the selected item depending on the selection from the table. At later stage I also need to add forms to add data. Now, how to add a Navigation Controller in that view for drill down? Can we convert a View Controller to Navigation Controller just by adding a Navigation bar at the top?

• Dice face value recognition

  - by Jakob Gade

  I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.

• Mysql out of disk space

  - by Paddy

  I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

• javascript removeChild() and appendChild() VS display=none and display=block|inline

  - by Kucebe

  I'm developing a web application that shows some controls and descriptions dinamically (I don't want to use jQuery or other libraries). At this moment i make appear and disappear controls using: element.setAttribute("style", "inline"); and element.setAttribute("style", "none"); but i'm thinking about using: element.appendChild(childRef); and element.removeChild(childRef); So, which one is the best solution in terms of system speed and elegance of the code? (and of course, are there better solution?)

• Why does Chrome ignore local jQuery cookies?

  - by Nathan Long

  I am using the jQuery Cookie plugin (download and demo and source code with comments) to set and read a cookie. I'm developing the page on my local machine. The following code will successfully set a cookie in FireFox 3, IE 7, and Safari (PC). But if the browser is Google Chrome AND the page is a local file, it does not work. $.cookie("nameofcookie", cookievalue, {path: "/", expires: 30}); What I know: The plugin's demo works with Chrome. If I put my code on a web server (address starting with http://), it works with Chrome. So the cookie fails only for Google Chrome on local files. Possible causes: Google Chrome doesn't accept cookies from web pages on the hard drive (paths like file:///C:/websites/foo.html) Something in the plugin implentation causes Chrome to reject such cookies Can anyone confirm this and identify the root cause?

• Top 3 reasons not to develop a "blog system" that generates aspx files on the fly.

  - by klausbyskov

  In this question the OP implies that he wants to base the blog system he is developing on automatic creation of .aspx files, one for each new blog entry. In my answer to his question (which is related to something else), I told him that I would discourage him from using such an approach, but without giving any real reasons. He is now wanting reasons why it is not a good idea, and I'm using this question to see if the community can come up with a compelling enough list of reasons for him to use another approach, such as one using a dbms, code-reuse, url-rewriting, MVC, and what not.

• Where are config files for class libraries physically located?

  - by BadNinja

  My guess is that this question will fall under the category of "duh", but, nevertheless, I'm confused. When using config files in, for example, a Windows Forms Application, the config file can be found in C:\Program files\CompanyName\ProductName\Application.exe.config. However, with the class library I'm developing I do not see a "ClassLibrary.dll.config" file in the install folder after installing it (in tandem with another project) from Visual Studio. Even though I do not see the file anywhere, retrieving data from it works correctly. Plus, running the following code from a method within the class library returns the path you would expect: C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config. If someone could shed some light on what I'm missing here, that would be really awesome. public static string MyMethod() { Assembly assem = Assembly.GetExecutingAssembly(); Configuration config = ConfigurationManager.OpenExeConfiguration(assem.Location); return "The assembly location was: " + assem.Location + Environment.NewLine + "The config file path was: " + config.FilePath; // Gives me "C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config" }

• How to setup a DotNetNuke Development Environment with Source Control?

  - by Joosh21

  My team is developing a new DotNetNuke web application and would like to know what is recommended to setup a development environment with source control and automated builds? We would like to keep the DNN source code separate from our custom modules and extensions source code. The DotNetNuke Compiled Module template for Visual Studio wants us to store the source code in the DesktopModules directory of the DNN source code and output to the DNN source code bin directory. Is this the recommended structure? I would rather keep the files in different locations, but then it becomes more difficult to run and debug locally as it would require an install of the module for each change. Also, how should an automated build deploy any changes? How have others set this up? Is there a recommended best practice?

• Experiences with UI Automation and WPF

  - by soren.enemaerke

  We are developing a rather large WPF based application and would like to include some automated UI testing in our test suite (which already contains a number of unit tests). The UI Automation Framework from Microsoft partly sounds like a perfect fit for programatically launching and interacting with the application in a test setup. However, I've struggled to find solid references for samples and experiences with the technology, the articles and small samples available on MSDN is not enough to convince me that it is a solid choice. So, does anybody have real world experiences using the UI Automation Framework in their test suite? What are the caveats and the gotchas? Any best practices when written tests scripts, can you "record and replay" to a scriptable format, how much should you facilitate the testing from the application, how did you incorporate it in the automatic build? Should we be looking in another direction than the UI Automation Framework? Feel free to post you experiences here or link to some good references I might have missed

• Flex/Actionscript: Unable to add archive file

  - by biggusjimmus

  I have an Flex 4 application that I am developing in Flash Builder 4. I'm trying to use a library developed by a coworker, which was delivered as an SWC. I added the library to the Library Path in the project properties. Component set: MX + Spark, Framework linkage: Merged into code. When I attempt to instantiate a component from this library, I get the following error: unable to add archive file: [library].swc$locale\en_US\..\..\resources\images\AcceptButton.png (The system cannot find the path specified) When I unzip [library].swc, the image does exist in .\resources\images\AcceptButton.png as I would expect. Any suggestions to go about resolving this would be much appreciated.

• Open source software

  - by Maurizio Reginelli

  What is your opinion about open source software? It is helpful in many situation, for example a community can correct many bugs. But I also think that it can be dangerous for a software developer. If you develop an application and share its source code, a lot of applications can grow with a little effort, simply copying part of your code. For example, if you develop a library in WPF which can be used to create charts, and share your code, this can be dangerous for companies which main business is WPF component developing. And obviously it is dangerous for a software developer who works in that company. What do you think about this?

• Speed up compilation with mockito on Android

  - by pbreault

  I am currently developing an android app in eclipse using: One project for the app One project for the tests (Instrumentation and Pojo tests) In the test project, I am importing the mockito library for standard POJO testing. However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclipse. The cause seems to be that the whole library is converted each time. So basically, each time a make a modification that I want to test, I have to wait 30 seconds. The only workarounds that I have found so far would be: Disable "Build Automatically" Create a project that includes only pojo tests and put mockito only there. Use another library that compiles faster (e.g. easymock) Any other suggestion?

• custom button: properties change, button should be redrawn

  - by Rutger

  Hi I'm developing an Android app. I have class derived from button to represent a special type of button. This special type has some properties (integers) and according to these one or more circles have to be drawn on top of the button. So I overrode the onDraw function, which looks the values up and accordingly draws the circles. But the class has a function to set new values for its properties. So new values are set but the changes are not reflected in the UI. It seems like the onDraw function is not called. When later I click the button or show a pop up message above my interface the onDraw function is called and the button is drawn correctly. So my question: when changing the properties how can I say that the button has to be redrawn? Thanks a lot!

• how to use different oracle character sets in one application

  - by Peter Shower

  Hi Guys, i'm developing a 32bit Client-Application with Delphi. From this application I need to connect to databases on two different servers. First databse character set ist WE8MSWIN1252, the other server decodes with WE8PC850. Setting the client NLS_LANG parameter to the correct value solves correct sql-query results. Unfortunately this (the client character-set) seems only to be recognized on applications startup (first connect to oracle). I need to change the client-characterset at runtime. Oracle client seems to store the character set an application used to connect! beside: I#m using udl-files to setup the connections (Microsoft OLE DB - driver) what can I do?

• as3 swc component preview through code

  - by David

  I am developing an as3 swc-based component that populates its contents entirely through actionscript in the constructor (e.g. sprite.graphics.lineTo...). When I drag the component onto the stage, it is empty. If I export my movie, everything works perfectly, but I also need the live preview to work. I could get around this with a placeholder graphic, but I would much rather leave it purely as code. Is there any way to get around this? Thanks, David.

• How do you find time for improving your programming skills?

  - by Snehal

  I'm a Java/J2ee programmer working in India. I'm very passionate about programming and I constantly strive to hone my programming skills by reading blogs, solving Project euler questions, learning new technologies, developing small apps etc;. But I find it very difficult to manage my time. Working for 12 hrs a day in office leaves me stressed out and spend my weekends with my family. So i hardly have like 5-6 hrs per week to actually work on something of my interest which will help me improve. How do you manage time so that you find time to improve your current standing? EDIT: 12 hours includes 1hour of travel & 1 hr of break(lunch/coffee). Effectively I work for 10 hours per day in office which is mandated by my organization. -Snehal

• What WPF frameworks should I use?

  - by joebeazelman

  I'm a newbie to WPF and I'm developing a brand new windows desktop application and I would like your opinion on what WPF framework I should use. I know this question has been asked before, but the last question was asked at least several months ago. A lot has changed since then. Right now, I'm using MVVM Light which is more of a library than an actual framework, as the name suggests. I’m looking for something more comprehensive. I prefer a framework that I can use on future WPF projects. Consequently, it should be general purpose and productive. Any insights or suggestions?

• iPhone SDK: am I still allowed to develop with SDK 3.1.3 on Leopard?

  - by BoltClock

  Mac OS X Snow Leopard's been in stores for a while now. Sadly, the Mac that I'll be developing on is still running Leopard, and I don't have admin access to the Mac either so I can't do anything about the OS version. Therefore I can only use iPhone SDK 3.1.3, which we've obtained thanks to this answer, to start building apps on that Mac. Am I still allowed to develop apps with this setup and deploy for iPhone OS 3.x to the App Store? Keyword is allowed because all I've seen so far are technical questions/answers, but I'm not certain if Apple's going to be a jerk and shun me because I can't use a Snow Leopard Mac despite having only started this year (and I don't even want to get started about iPhone SDK 4's revised agreement, not with its NDA still in place...).

• iPad/iPod: autoRotate resizes view in window

  - by Jasconius

  Developing an iPad interface, I have a scenario where I have a UIViewController which manages a view that gets placed directly as a subview of the main UIWindow. Before being placed in the UIWindow, that view gets resized to a non-standard size, let's say, 768x460, and positioned at the bottom of the screen. When rotating the device, the autoRotate feature of the UIViewController causes the view to be resized so that it fills the entire UIWindow space. I thought this might be because in the XIB, the view is set to window size, but when I changed it to reflect the desired size, it still expanded it to the window size. Then I went into the MainWindow XIB and turned off autoresizeSubviews, and it still happens. This is a very frustrating problem, I am hoping that there is merely something obvious that I am missing out on. Anyone have any bright ideas?

• Visual studio asp.net code behind file not showing errors

  - by Mahesh

  Hi, I am developing a web application in which I am suddenly facing an issue. I have a webpage which contains many controls, one of the control is JQuery color picker. Now, I am upgrading my system with telerik controls. As part of this process, I replaced textbox(txtcolor) with radcolorpicker with a different id(colorPicker). Suddenly, my code behind file is not throwing any errors like 'unable to find txtColor'. It is running successfully without build errors. But, when I open the page, system is throwing runtime exception(txtColor not found) which is correct. I tried to change other controls with asp.net controls, still the problem persists. So, I dont think it is anything to do with telerik. Could you please let me know how can fix this issue?? Thanks, Mahesh
