• Sharing state/changes across ViewModels

  - by joshperry

  I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

• Sharing a fabfile across multiple projects

  - by Matthew Rankin

  Fabric has become my deployment tool of choice both for deploying Django projects and for initially configuring Ubuntu slices. However, my current workflow with Fabric isn't very DRY, as I find myself: copying the fabfile.py from one Django project to another and modifying the fabfile.py as needed for each project (e.g., changing the webserver_restart task from Apache to Nginx, configuring the host and SSH port, etc.). One advantage of this workflow is that the fabfile.py becomes part of my Git repository, so between the fabfile.py and the pip requirements.txt, I have a recreateable virtualenv and deployment process. I want to keep this advantage, while becoming more DRY. It seems that I could improve my workflow by: being able to pip install the common tasks defined in the fabfile.py and having a fab_config file containing the host configuration information for each project and overriding any tasks as needed Any recommendations on how to increase the DRYness of my Fabric workflow?

• Cakephp, Retreive Data for HABTM Models using conditional find

  - by ion

  There are 2 Models: Project & Category that are bind with HABTM relationship. I would like to perform a search from projects controller that can do the following: FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised' Apologies for the syntax, I'm no sequel expert. What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down) I hope I made myself clear.

• Visual Studio 2008 XML Documentation

  - by Pablo

  Hello, I can't seem to find the "Build" option under "Configuration Properties" folder in the Property Pages of my project. I've been looking everywhere trying to figure out how to do it. I followed the direations here: http://msdn.microsoft.com/en-us/magazine/cc302121.aspx More specifically here: http://msdn.microsoft.com/en-us/library/azt1z1eh.aspx ("To build the XML Documentation sample within Visual Studio" section) I want to generate XML comments for my project in the build, but my "Configuration Properties" window does not have "folders" or a "Build" option under it. I'm using Visual Studio Team System 2008, any ideas? EDIT - This is a website [project-less] and it is written in both C# and VB.NET. Do I need to download any tools? I found GhostDoc but that's not helping me very much.

• Eclipse buildpath automatically taking all JARs of a internal directory

  - by Niko

  How do I configure my project buildpath to have a set of .jar files located in the same directory automatically included in the buildpath ? Meaning that adding a new .jar file to this directory (and refreshing the project) updates the buildpath ? Rem : I am not working in a Webapp but in a standalone Java app. I know that it is possible in a Dynamic Web Project to have all the .jars located in WEB-INF/lib to be included in the build path. Is it possible to do kind of the same include but in standalone app ? I am using Eclipse 3.4

  - by mkafkas

  I need to find out that how many times and which files are fixed or changed due to a bug between two specific dates in an open source project which uses Trac. I selected Webkit project for that purpose. (https://trac.webkit.org/) However, it can be any open source project. What can I do for that? How do I start? Do i have to use version control systems like svn or git for intergration? I am kinda newbie for these bug-tracking and issue-tracking systems.

• Cannot debug tests using Resharper

  - by Mike

  Hi, I'm not able to debug my tests using Resharper-Debug option in my project. I have seen this issue raised by lots of people, but has't come across a solid suggestion which solves my issue. The strange thing is that, if I create a sample project and write a simple unit test, I'm able to debug it without any issues.However when I try to do this in my current project, it simply throws a dialog box saying "Cannot Launch Debugger".I have checked this with my peers, and they does't face this issue :( Also I don't have any issues while running the test. It's an XP machine and following is the version of resharper: JetBrains ReSharper 5.1 C# Edition Build 5.1.1753.4 on 2010-10-15T15:51:30 Licensed to: XXXXXXX Plugins: none. Visual Studio 9.0.21022.8.

As you can see the the first one has a Maven dependencies Library but the second one has been changed to JRE System Library. I use mac os lion and eclipse indigo. Anyone how knows why is like that?

• SVN correct directory structure

  - by jax

  I followed this tutorial to setup SVN on my Fedora box http://www.ashishkulkarni.com/installing-subversion-on-fedora-linux/ It worked. However, there is no trunk, tags or branches when I set this up. In the tutorial he creates a sandbox project /svn/repos/sandbox Now I am assuming that all projects will go under repos /svn/repos/project1 /svn/repos/project2 When I view the project there are no trunk, tags or branches, I have not yet checked in any project, will these appear when I do that? As I understand all my files should go below the trunk. What are the tags and branches for? Just some clarification about the structure would be nice. Thanks.

• Set plugin’s version on the command line in maven 2

  - by larry cai

  I generate default quickstart maven example, and type mvn checkstyle:checkstyle, it always try to use the lastest SNAPSHOT version, probably it is wrong in my nexus server, but How can I set plugin's version on the command line in maven2, like 2.5 for checkstyle instead of 2.6-SNAPSHOT C:\HelloWorld>mvn checkstyle:checkstyle [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'checkstyle'. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error building POM (may not be this project's POM). Project ID: org.apache.maven.plugins:maven-checkstyle-plugin Reason: Error getting POM for 'org.apache.maven.plugins:maven-checkstyle-plugin' from the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact's metadata. org.apache.maven.plugins:maven-checkstyle-plugin:pom:2.6-SNAPSHOT from the specified remote repositories: nexus (http://localhost:9081/nexus/content/groups/public) for project org.apache.maven.plugins:maven-checkstyle-plugin I guess it could be "mvn checkstyle:2.5:checkstyle", unfortunately it is not. Surely if I set build dependance in pom.xml, it will work, but I want to see how command line can works

• How do you install cocos2d-iphone on the Mac?

  - by johnfromberkeley

  There are no good instructions for installing cocos2d for iPhone on the mac. I downloaded the current build from git, a folder called "cocos2d-iphone-0.99.1". i put this folder in /Developer/Libary. Q: is this right? I tried running the file called "install_template.sh". it said the templates were already installed. Instead, I manually dragged the templates folders where they belong, and they ~do~ appear in the XCode's "New Project" dialog. When I create a new cocos2d project, I see all these red links for project files, instead of the regular black links. When I try to open them in the finder, nothing happens. I can tell that something is not linked. Can someone please help walk me through this? Thanks!

• How can I configure a Hudson job to use a specific JDK?

  - by rewbs

  I have a number of projects running on a Hudson slave. I'd like one of them to run Ant under Java6, rather than the default (which is Java5 in my environment). In the project configuration view, I was hoping to find either: An explicit option allowing me to set a custom JDK location to use for this project. A way to set custom environment variables for this project, which would allow me to set JAVA_HOME to the JDK6 location. The would make Ant pick up and run on Java6 as desired. Is there a way to do either of the above? If one of those facilities is available, I can't see how to access it. I'm running on Hudson 1.285. I would rather avoid using an "execute shell" operation instead of the "invoke Ant" operation if possible: my slave is on z/OS and Hudson doesn't seem to create the temporary shell scripts properly on this platform (probably an encoding issue).

• eclipse + multiple checkouts of version-controlled projects

  - by Jason S

  We're using eclipse and svn. We keep the .project file in version control. The problem is, if you have more than one checked-out project (e.g. a trunk checkout and a feature branch) and would like them both to be available in Eclipse, you lose, because the .project files are identical and therefore can't both be imported into Eclipse. What's the right way to deal with this? (I'm mostly having to deal with this in TI's Code Composer v4 which uses an older version of eclipse, but I'm also going to need to do this in the regular Eclipse)

• Importing libraries in eclipse programmatically

  - by Krt_Malta

  Hi, Is there a way I could put a library (Jar file) into an Eclipse project programatically? Up to now I've managed to do an external reference to it programatically using IPath path = new Path("C:\\Hello\\jtwitter.jar"); libraries.add(JavaCore.newLibraryEntry(path, null, null)); //add libs to project class path try { javaProject.setRawClasspath(libraries.toArray(new IClasspathEntry[libraries.size()]), null); } catch (JavaModelException e1) { e1.printStackTrace(); } } however I'd like to copy the jtwitter file to the project folder programatically so I could reference it as jtwitter.jar only. Can this be done please? Thanks a lot and regards, Krt_Malta

• Problem with deployment of windows application using setup wizard.

  - by Mike

  I have some xml files, which are used in my application. They are stored in the same folder with application , in subfolder DATA: "C:\MyProject\DATA\". To get the DATA folder path i use this code : static public string GetDataFolderPath() { string s = System.IO.Directory.GetCurrentDirectory().Replace(@"\bin\Debug", ""); int i = s.LastIndexOf(@"\"); s = s.Substring(0, i); i = s.LastIndexOf(@"\"); s= s.Substring(0, i); return s + @"\Data\"; } So when i want to deploy my application, i create a setup project, and add the DATA folder to Application folder. But after i install the program f.e. "C:\Project"(DATA folder- "C:\Project\DATA" i got the error: "folder C:\DATA is not found". What i need to change to make things working after deployment. Why it looks for the DATA folder on 1 level higher?

• Questions to ask a client before beginning a website

  - by Jason

  I am aware of this question which deals with the technical aspects of website construction, but I was unable to find any place with suggestions on knowledge you must obtain from a client before undergoing a project. As someone who freelances on the side, I think this could be incredibly useful. What important questions must one ask the client (and require an answer to) before undergoing a website? or, in other words, What must you know about the project before starting it? This can range from "When do I get paid?" to "How many pages will the site be?". I believe this is relevant to programming because you must know how to communicate with your client to get all the information necessary before you can begin programming. If not, downstream changes can put a serious delay on the project from things not hashed out beforehand. Thanks!

• How to add model entity property in WCF RIA service

  - by Oblomingo

  I'm developing silverlight app with WCF Ria service. I'm using MS SQL database and Entity Framework as ORM framework (Database first method). Model with domain service are in separate project - App1.Data. Silverlight and generated model proxy classes are in App1 project. I want to add property to model entity class EntityClass to get this property on client side. So I did it that way - added this class to project App1.Data: public partial class EntityClass { [DataMember] public List<EntityClass2> PropertyName {get; set;} } After rebuilding EntityClass proxy on client side doesn't have this new property. Where is my mistake?

• Is there an ORM that allows a "plugin" to extend the database?

  - by IP

  So, I've been searching for the answer to this, but I can't find anything I have an Entity Framework Model (MyModel1) - for now, we'll say this contains a "Users" table It's part of a big app, that has a references to an "Addresses" project The addresses project contains an Entity Framework Model (MyModel2), this contains a Users table, and an Addresses table (pointing to the same database. The main app has a control that edits the user, and in that control it has an "addresses" control which actually exists in the "Addresses" project. To make this work, the User control passes the User object down to the addresses control, however, as the User that's been passed belongs to MyModel1 and not MyModel2, another User object has to be loaded up, then it can be used. This isn't ideal as I've had to load up the User twice. Is there a way of say, MyModel2 extending MyModel1, which effectively just adds a relationship to "User". Or is there an ORM that would handle this better? Or even a design pattern that would handle this better?

• Guidelines for solution source code organisation(OO/DDD)

  - by fearofawhackplanet

  I'm starting on my first business project (.NET) and am trying to follow DDD principles. Are there any guidelines or common patterns for orgaining source code and namespaces? For example, do your domain objects go in a namespace MyProject.Domain or whatever? Would you separate the concrete implementations and the interfaces? In different namespaces? Different folders? Different solutions? I know a lot of this is subjective and dependent on project size, but a few pointers or suggestions to get started on a relatively small but extensible n-tier project would be useful.

• Linkage of namespace functions

  - by user144182

  I have a couple of methods declared at the namespace level within a header for a class: // MyClass.h namespace network { int Method1(double d); int Method2(double d); class MyClass { //... } } then defined in //MyClass.cpp int Method1(double d) { ... } int Method2(double d) { ... } This project compiles cleanly and is a dependency for a ui project which uses MyClass. The functions were previously member functions of MyClass, but were moved to namespace since it was more appropriate. My problem is the ui project complains when it gets to the linker: 1network.lib(MyClass.obj) : error LNK2001: unresolved external symbol "int __cdecl network::Method1(double)" (?INT@ds@sim@@YAHN@Z) 1network.lib(MyClass.obj) : error LNK2001: unresolved external symbol "int __cdecl network::Method2(double)" (?CINT@ds@sim@@YAHN@Z) What am I doing wrong?

• Git: How do I rewind the Master branch on the remote origin

  - by user277260

  I made 5 commits to Master branch when bug hunting on a private project and pushed them to the remote origin (my own private vps). Then I saw that commits 4 and 5 were going to cause trouble elsewhere and I need to undo them, so I checked out commit 3 again, made a new branch "Dev" from that point, and did a few more commits fixing the issue properly. Then I did git reset --hard HEAD~2 on Master to pull it back to the point that I branched Dev. Then I did git merge to fast forward Master back to the end of the Dev branch. So now I have a local repository, with Dev and Master both pointing to the same, up to date version of the project with the latest bug fix. Problem is, when I try to push the project now to the origin, it fails and gives me an error message: ! [rejected] master - master (non-fast forward) error: failed to push some refs to 'myserver...myproject.git' What have I done wrong, and how do I fix it? Thanks
