• Programming on Leopard for iPhone OS 3.1.3

  - by Blank6

  Hey, I got Leopard with XCode 3.1 and SDK 3.0, when opening the organizer and trying to debug on my ipod I received "The version of iPhone OS on "..." does not match any of the versions of iPhone OS supported for development with this copy of xCode...". It tells me with my xCode I can only develop for iPhone OS 3.0 or less, so I downloaded the new xCode + SDK installation bundle, knowing the SDK can't be installed on Leopard. In the installation it tells me "If you don't want to install the SDK, press disagree", and so I did, but in the next screen he forces me to choose a drive for the SDK, and then says "you can't install the SDK on leopard system", and I can't pass this screen. My question is: is it even possible to program on Leopard for iPhone OS 3.1.3? I really want to debug my apps on my iPod (framework 3.1.3, 3G) Thanks ahead!! By the way: I can't so simply upgrade to snow leopard because it's a hackintosh, so I prefer a different way..

• Best CMS for doing private site with Charting

  - by anderswid

  I'm really new to website development and for a project I need: No public pages. All private. Login+Password (Users, Admins) Being able to upload XML-files from Android device Parse this XML into something I can plot. Easy charting. Admin users being able to read all sub-users uploads. Doesn't have to look good. No blog-post. Strictly XML-Charts. I thought about using Wordpress, but I don't know if it's the best idea. I can code, but I don't have to much PHP + MySQL experience. Maybe there's something simpler? Thanks for taking the time.

• XSD data set with Oracle database

  - by Ed Woodcock

  Hi folks, I'm having a major issue with an XSD dataset mapping thingy that I'm using within my current project. We are using XSDs for some data abstraction (it's quicker and debatably more maintainable that using Parameterised SQL or a StoredProc), and on my machine (running in the VS development environment) thy're working fine. However, on the Pre-production server we use for our testing, the XSDs are not working correctly: some method calls will fail with the following error: System.ArgumentException: Value does not fall within the expected range. at Oracle.DataAccess.Client.OracleParameter.set_DbType(DbType value) Has anyone ever encountered this issue before? The methods being called are simple select statements using 1-3 parameters, and as I said before they work fine on my machine.

• Is there a certain IIS configuration required to allow a functioning .Net 4.0 ASP.Net MVC 2 Azure ap

  - by erg39

  I just installed the Azure 1.2 tools update and would like to get to work on an Azure project running locally using ASP.Net MVC and .Net 4, but I cannot get MVC pages to load. If I just create a new Azure project in VS 2010, add a ASP.Net MVC web role, and run the application, pages never load. It appears that routing is somehow at fault as controller actions never get called, but if I add other pages to the project (like .htm or .aspx) they will load in the browser. It all works fine with a new project using .Net 3.5, MVC 2 project in the Azure development environment; it all works fine with .Net 4.0 MVC 2 project that is not running in Azure; only the combination does not work. Environment is Win 7 x64 (IIS 7.5), VS 2010, Azure tools 1.2 Is there some magic IIS setting I need to change or something? Any ideas?

• dynamic dashboard interface

  - by user208081

  I want to create an interface similar to the following in Silverlight. http://demos6.dundas.com/Silverlight/ I need to create a dashboard where different elements can be re-arranged using Silverlight. The dashboard elements can be different usercontrols that in turn may contain charts, guages, grids...... The user should be able to dynamically add and remove dashboard elements. The user should also be able to use drag and drop to reposition the dashboard elements. If there are some code samples to get me started, that will be great as we are just starting out on some Silverlight development. Thanks, Pratik

• ASP.NET MVC reminds me of old Classic ASP spaghetti code...

  - by EdenMachine

  I just went through some MVC tutorials after checking this site out for a while. Is it just me, or does MVC View pages brinig back HORRIBLE flashbacks of Classic ASP spaghetti code with all the jumping in and out of HTML and ASP.NET with yellow delimiters everywhere making it impossible to read? What ever happened to the importance of code/design separation?? I was really sold on the new technology until the tutorials hit the View page development section. Or am I missing something? (And don't say you can use the template to help because it's jsut moving the spaghetti to another location - sweeps it under the rug - it doesn't fix the problem)

• Open Source Contribution for a newbie programmer.

  - by sasayins

  Hi, I am teaching programming to my nephews and I want them to improve their skills by contributing to open source projects. Now my question is, do you know any open source project that suit for a newbie programmer. What I mean is, the project does not have a large codebase, the project is very interesting and the project is written in C because I chose C language as their starting language but you can suggest other project made in other language. My goal here are to improve their logic by reading other source codes, familiarize to the available development tools like bug tracker, version control system, etc. and open their interest in open source community. Thanks. =)

• In javascript, how do I find out the name of a function from within that function?

  - by roryhewitt

  The title should make it clear. Is it possible from within a function to determine the name of that function? Basically, I'm adding some debugging code to a number of functions, and I'd like to be able to simply add the following line inside every function: if (global_debugOn) alert("Processing function " + function-name); How can I get 'function-name'? Yes, obviously I could simply type in the function name (after all I'm typing in the whole alert bit), but that's a hassle to do, especially if there is a nice simple way of retrieving it dynamically. Plus, as function names change during development, I'd like to keep it up-to-date... I hoped that maybe the arguments attribute might hold this (e.g. arguments[0], like in C), but I couldn't get it to work. I'm not even sure if arguments works anyway. Thanks! Rory

• Sending Subversion Change Log Info Via Hudson

  - by GrumpyCanuck

  I'm trying to integrate Hudson into our development process, and everything is going smooth except for one thing. I had been using Phing to do deployments, and one of the things that was being triggered was an email to our tech support email address containing a list of all the commit messages between the last time code was deployed and the present SVN revision. I was doing something like this: read in a file from the root directory of the currently-deployed application that contains the SVN revision when the app was deployed place that value in a Phing variable insert that value into a command to send the SVN commit messages via email create a file in the root directory of the newly-deployed application that contains the current SVN revision I'd like to be able to add that information to the email that gets sent out by Hudson when a successful build goes out. Any pointers on how to accomplish this task in Hudson would be greatly appreciated.

• Can SqlAnywhere's UltraLiteJ DB tables be viewed in the Database Explorer of the Eclipse IDE

  - by Tobias

  Hi, I am developing a Blackberry app which should be able to access a DB. Here is my development environment and the tools I am using: Eclipse (Galileo) IDE with the Blackberry plugin installed. Blackberry OS 5.0 SQLAnywhere's DB 11 with UltraLiteJ (I am targeting Blackberrys running OS 4.1 and above) I have successfully executed a sample project for building a Blackberry application that uses the UltraLiteJ DB, following the tutorial in the UltraLiteJ documentation*. The tutorial creates, populates and retrieves data from the DB using java code. Now, I want to be able to access the tables and view data in them from the Eclipse IDE. Something similar to the FireFox plugin for SqlLite or say the Enterprise Manager for Sql Server 2005 which is a DB Explorer providing access to the StoredProcedures, Views, DB Diagrams etc. for a Database. Can someone please direct me as to how to tackle this problem? I hope the question is descriptive and clear. Much Obliged. *http://dcx.sybase.com/index.html#1101en/ulj_en11/uj-ch03.html

• Cloning just a particular directory with hg?

  - by leeand00

  I come from a Subversion background, but I am slowly migrating to Mercurial. When starting on many of my projects, I would setup a development environment that was configured to a particular starting point in developing an app/webapp/program (much like a Maven 2 archetype, but not necessarily Java/Maven). Later I would checkout this archetype/template project out of my svn repo by its particular path; and than export the working copy from version control by the repository; so that I could import the working copy back in to another repository without adding the changes that I made to the working copy to the base the template/archetype project. I've tried doing the same thing in Mercurial, and I've run into a wall since I can't check out, er..um..no, clone a specific path from the hg repository. If I want to achieve the same sort of functionality using Mecurial, what should I do? Use tagged branches? The archetypes/template projects are very different, but I'd like to keep them in the same repository.

• Use of COM object in IIS 7

  - by Wouter d.A.

  Hi all, I am currently moving an ASP.NET web-project from an IIS 6 to a IIS 7 hosting environment. Everything seems to be running OK, except my calls to a COM object. I can perfectly instantiate an object of the COM type, but when I call one of its methods, the IIS crashes. The event log reports an error code "0xc0000374", which indicates a heap corruption. When I run the application inside the visual studio development server, everything goes well and the COM object code gets executed without any errors. This is also the case when the application is hosted on an IIS 6 machine. I have looked through all settings of the IIS 7 and have not found anything configurable for COM objects, like security or ... I have been struggling with this for a while and I'm out of ideas. Does anyone have any experience deploying COM objects on IIS 7? Your help would be very appreciated!

• Git - switching between branches in the middle of work

  - by Art

  For various reasons (code review mostly) I need to switch from current development branch to other branches quite often. Currently, I use either 'git stash' to shelve the uncommitted changes, checkout other branch, then switch back and do 'git stash apply' However, sometimes I'd have some newly added files there, which are not tracked. Unfortunately, stashing does not affect them. In this case I'd have to add them to the index and stash. What I am looking here for is a workflow where I'd have to perform a minimal set of actions to switch the branches, preferably avoiding adding of files into the index.

• Blackberry Widget vs Java SDK

  - by rithanyalaxmi

  Hi, I am a newbie to this forum,I was going through the documents of both Blackberry Widget and Java SDK. I have the following doubts to get clarified:- 1) Advantages and disadvantages of Java SDK and Widget SDK? 2) When to go for Java SDK and Widget SDK? 3) Both Java and Widget applications require the latest blackberry OS 5.0? OR whether they are compatible with the lower versions as well? 4) Whatever developed with Java SDK can be done with widget SDK? similarly the vice-versa? 5) Is it possible to create the .java classes for Widget application development? 6) Whether all the blackberry models supports both Java and Widget ? 7) What are the Databases the blackberry Java and Widget supports? Please do shed some light into this as i was unable to find a suitable documentation on these. Thanks, Rithu

• What can explain std::cout not to display anything ?

  - by Benoît

  For whatever reason, std::cout does not display anything with my application. The description of my development environment follows. I am working on a Qt application using Qt Creator. Since Qt Creator can't be launched from my station (XP64), i am currently developping it with Visual Studio 2008 and the Qt plugin (by importing the .pro project file). Everything seems fine and the application works. In some cases (depending on command line arguments), i don't want to launch the HIM, just to display a few sentences in the CLI (command line required arguments, for instance). I don't get any error, but nothing is displayed. The corresponding code, which i am sure is run is the (classical) following : std::cout << "is this going to be displayed ?" << std::endl; Do you have any idea why nothing is displayed ?

• Calling sp and Performance strategy.

  - by Costa

  Hi I find my self in a situation where I have to choose between either creating a new sp in database and create the middle layer code. so loose some precious development time. also the procedure is likely to contain some joins. Or use two existing sp(s), the problem of this approach is that I am doing two round trips to database. which can be poor performance especially if I have database in another server. Which approach you will go?, and why? thanks

• msxml domdocument stops working when I move to staging server

  - by blockhead

  I have some code that looks like this: Set xmlHttp = Server.CreateObject("MSXML2.ServerXMLHTTP") xmlHttp.Open "Get", myRSSfile, false xmlHttp.Send() myXML = xmlHttp.ResponseText Set xmlResponse = Server.CreateObject("MSXML2.DomDocument") xmlResponse.async = false xmlResponse.LoadXml(myXML) Set xmlHttp = Nothing Set objLst = xmlResponse.getElementsByTagName("item") Set xmlResponse = Nothing NoOfHeadlines = objLst.length - 1 Response.Write NoOfHeadlines This worked find on my development server. When I moved it over to a staging server (which I have no control over, and no nothing about), NoOfHeadlines returns 0. It seems obvious to me that DomDocument is not working the way its supposed to. Is this a version issue? How do I find out what version of DomDocument is on the staging server? Is there another possibility?

• Reloading Rails Directories on Change for Dev: Not Lib!

  - by yar

  I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

• Marshal a list of objects from VB6 to C#

  - by Andrew

  I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.
