• MSVC 2008 - Unresolved External errors with LIB but only with DLL, not with EXE project

  - by Robert Oschler

  I have a DLL that I am trying to link with a libjpeg LIB using MSVC 2008 that is generating Unresolved External Symbol errors for the libjpeg functions. I also have a test project that links with the exact same libjpeg library file and links without error and runs fine too. I have triple-checked my LIB path and dependent LIBS list settings and literally copy and pasted them from the EXE project to the DLL project. I still get the errors. I do have the libjpeg include headers surrounded by extern "C" so it is not a name mangling issue and the unresolved external warnings show the "missing" libjpeg functions as undecorated (just a leading underscore and the @ sign parameter byte count suffix after each name). What could make the linker with the DLL project be unable to find the functions properly when the test EXE project has no trouble at all? I'm using the pre-compiled 32-bit static multi-threaded debug library which I downloaded from ClanLib. Thanks, Robert

• How to add class to openframeworks project in VS2012

  - by Mr Bell

  I am normally a C# guy but trying to get into c++. I made myself a new openframeworks project by copying and pasting one of the example projects and then renaming everything to my project name. (If there is an easier way, I would love to hear it) This project has the .cpp and .h files in a sub folder called "src" which are in turn organized into virtual folders (filters???) in visual studio. How can I add a class to this project from within visual studio? If I right click on the src filter in the solution explorer and hit add class. It creates the class files at the root of the project not in the src folder. I mean it does this both in the solution explorer and where it physically places the files. This is a problem because I can't include my class files in the rest of my app, presumably because they aren't in the same folder What is the proper way to add a class file?

• seeing C# windows forms project code from F#

  - by Pessimist

  I have a C# Windows Forms project open with some C# code in it. Question: How can I have an F# file that I can write F# code in but still referencing all the C# code I have on Form1.cs (including the GUI). I can successfully do this: - Create a C# Windows Forms project - Create a F# Library project - Reference the F# Library DLL from my C# project - That way I can call F# functions from C# But I still can't see my buttons and textboxes from F# I understand that that is because it's a library and it can't reference System.Windows.Forms So how do I fix this? I don't want it to be a library or this or that, I just want it to be a file that will allow me to write F# code while being able to reference my C# Form and code. I guess you can say I want an F# file that is also a "partial class Form1" so that I can continue writing code for the same Project, but using F# instead. How do I do that?

• Wrong assembly-references for Silverlight Sketchflow project in Blend 3

  - by persistent

  Hello, In my installation of Blend 3, the SketchStyles are missing when a new project is created. I found out that this is because the following automatic references in the project are wrong: Microsoft.Expression.Interactions Microsoft.Expression.Prototyping.Interactivity Microsoft.Expression.Prototyping.RunTime Microsoft.Expression.Prototyping.SketchControls In the project references these all point to my project path (where they don't live). If I remove them manually, and instead set the references to ie this: "c:\Program Files (x86)\Microsoft SDKs\Expression\Blend 3\Interactivity\Libraries\Silverlight\Microsoft.Expression.Interactions.dll" everything works. Any ideas on why, and how to fix this? Could it be the project template somehow? TIA

• Data Integration/EAI Project Lessons Learned

  - by Greg Harman

  Have you worked on a significant data or application integration project? I'm interested in hearing what worked for you and what didn't and how that affected the project both during and after implementation (i.e. during ongoing operation, maintenance and expansion). In addition to these lessons learned, please describe the project by including a quick overview of: The data sources and targets. Specifics are not necessary, but I'd like to know general technology categories e.g. RDBMS table, application accessed via a proprietary socket protocol, web service, reporting tool. The overall architecture of the project as related to data flows. Different human roles in the project (was this all done by one engineer? Did it include analysts with a particular expertise?) Any third-party products utilized, commercial or open source.

• Integrating a C project in the iPhone SDK

  - by iPhoneARguy

  Hello, This is my first time doing this sort of project so apologies if the question is silly. I've got a question about using a C project with a project in the iPhone SDK. I've dragged and dropped the C project into the iPhone project in Xcode (so it appears in the screenshot below). sjeng.h is a file inside GameEngine.xcodeproj, but when I try to include the header file, I not only receive an error, but the file it is looking for seems to be capitalized whereas the import statement is not. (I would post a screenshot but this is my first time doing something on stack overflow and I need more reputation points. The URL of the screenshot is here: http://imgur.com/AdrGL.png) Does anyone know what the problem might be? Thanks!

• Visual Studio Custom Project Template

  - by rauts

  Hi All, I have created a Custom C# Project Template for Visual Studio 2008. It works perfect. Only issue is that i have to place the zip file for the project template under the "C:\Documents and Settings\\My Documents\Visual Studio 2008\Templates\ItemTemplates\Visual C#" Now as this folder is specific to each user on the machine, I will have to make sure that all the users on the machine has the project template installed seperately. Is there any way I can just install it once and all the users can get this project template. In short can I change the Custom Project template Install directory?

• What ASP.NET MVC project files should I not add to Subversion

  - by Dan

  this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

• Django sys.path.append for project *and* app needed under WSGI

  - by GerardJP

  Hi all, Could somebody give me a pointer on why I need to add my project root path to the python path as well as the application itself in my WSGI file? Project base is called 'djapp', the application is called 'myapp'. sys.path.append(os.path.dirname(os.path.abspath(__file__)) + '/..') sys.path.append(os.path.dirname(os.path.abspath(__file__)) + '/../djapp') os.environ['DJANGO_SETTINGS_MODULE'] = 'djapp.settings' If I omit the line with "/../djapp/" the log tells my that 'myapp' can not be imported, even though 'djapp.settings' is. (validating 'djapp' was imported) It al runs properly with the ./manage.py command. there's a __init__ in the project folder. For testings sake, I see the same issue using addsitedir: site.addsitedir('/home/user/web/project/') site.addsitedir('/home/user/web/project/djapp') Thanx a lot. Gerard.

• How to add "make install" target to simple Eclipse C project

  - by Jim Flood

  I have a simple Eclipse C project. Is there a way to add a "make install" target to the generated makefile? I can't seem to find the right search keywords to find any useful information in the doc or by googling (i.e. there is too much noise and no signal.) I tried creating a simple project using the autotools plug-in but without being able to find any useful doc or tutorial that starts from scratch with a single C source file, I couldn't even get the project to build. Edit: I'll take an answer based on using the autotools plug-in if I can get my project to build. I don't see how to add an include dir (-I) a link dir (-L) or additional link libs to a new Hello World autotools C project. Is there any simple autotools plug-in tutorial that covers this?

• Adding files to the DPR file vs project paths in Delphi 2010

  - by Robert McCabe

  We are just migrating from D7 to D2010 and are having a debate about cleaning up the project paths. We have a number of directories with a large number of Pas files that are included on some project paths, but only a few of the files are actually used by any single project. One option is to eliminate the project paths completely and only have all used files in the dpr. The second option is to keep only the needed files in the dpr and have project paths to the directories for the rest of the files. Is there any argument for one option over the other?

• Problems adding static library QT project

  - by Smek

  I have problems adding a static library to my Qt project. I have two project one is my static library and the other one is a Qt GUI project. As I add all classes to my GUI project as c++ or header files everything works just fine but I want this to be in a separate library. When I select the option to add a library I check External library then I select the .a file I have build and the folder where my header files can be found because I am working on a Mac I select Mac as the target platform.

• 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.

• Google Glasses–A new world in front of your eyes

  - by Gopinath

  Google is getting into a whole new business that would help us to see the world in a new dimension and free us from all gadgets we carry we today. Google Glasses is a wearable tiny computer that brings information in front of your eyes and lets you interact with it using voice commands. It’s a kind of glasses(spectacles) that you can wear to see and interact with the world in a new way.  With Google Glasses, for example you can look at a beautiful location and through voice you can instruct it to capture a photograph and share it to your friends. You don’t need a camera to capture the beautiful scene, you don’t need an App to upload and share it.  All you need is just Google Glasses By the way these glasses are not heavy head mountable stuff, they are very tiny one and look beautiful too. Check out the embedded video demo released by Google to see them in action and for sure you are going to be amazed.   Last year December 9 to 5 Google posted details about this secret project and NY Times says that these glasses would be available to everyone at affordable cost, anywhere between $250 and $600. It is powered by Android OS and the contains a GPS, motion sensor, camera, voice input & output devices. Check out Project Glass for more details.

• How should a developer reject impossible requirements?

  - by sugar

  Here's the problem I'm facing: Quote From Project Manager: Hey Sugar, I'm assigning you the task of developing a framework that could be used for many different iOS applications. Here are the requirements: It should be able to detect the thickness of the thumb or fingers being used to manipulate the UI. With this information, all elements of the UI should be arranged & sized automatically. For a larger thumb, elements should be arranged nearer the center of the screen. For a smaller thumb, elements should be arranged nearer the corners of the screen. For a larger thumb, all fonts should be smaller. (We're assuming an adult in this case.) For a smaller thumb, all fonts should be larger. (We're assuming a younger person in this case.) Summary: This framework is required for creating user-friendly user interfaces programmatically. The framework should be developed in such a way that we can use for as many projects as needed, so it must also be very developer-friendly. I am the developer given this task, so my questions are as follows: How can I explain that these requirements are a little ridiculous? How can I explain that it would be better to concentrate on developing actual projects? How can I explain that even if this were possible, I wouldn't recommended developing such a thing? How do I say NO to this project politely, gently, and respectfully? How can I explain that even for a developer with 3 years of experience, this might not be possible?

• Planning milestones and time

  - by Ignas

  I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.

• What are some good seminar topics that can be used to improve designer&developer communication?

  - by tactoth

  Hello guys the thing I'll tell is what happens in the company I work for but I know it's more like a common issue in software companies. I'm development team leader in a internet service company that provides service that's very similar to dropbox. In our company we have mainly two divisions: the tech division and the designers division, both have their own reporting hierarchy. Designers focus on designing UI and prioritizing features, while developers focus on implement designers' ideas (more like being driven as our big boss has said). Then here comes our issue: the DEV team and DES team communicate very bad. DEV complain DES for these reasons: Too frequent changing of requirements Too complicated interaction (our DEV team has actually learned many HCI principles) Documents for design are incomplete, usually you just get 'design principles' and it's up to DEV to complete design details. When you find design defects, you ask DES team to resolve them, then DES team quickly change the principles and you gonna spend another several weeks because the change is so fundamental. While DES complain DEV for these reasons: Code architecture is not good enough to adapt to changing requirements (Obviously DES knows something about software development) Product design is about principles, not details. DEV fails to realize this. Communication should be quick and should be mainly oral. Trying to make most feature discussion in document for reference is too overloaded and doesn't make sense. As you can see, DEV and DES have different ideas on product design, and encourages very different practice. We have this difference because of the way we work. So our solution is that we should plan some seminars to make each part more aware of the way the other part work. Then my question is, what are some good topics for such seminars? Guessing some people may not think seminars can solve this problem, please also suggest your solution.

• Best way: restructure an existing Team Foundation Server (TFS) solution

  - by dhh

  In my department we are developing several smaller AddOns for some unified communication server. For versioning and distributed development we use a Team Foundation Server 2012. But: there is only one large TFS solution for all of our applications and libraries: Main Solution Applications App 1 App 2 App 3 Externals Libraries Lib 1 Lib 2 Tools The "Application" path contains all main applications. Those are not depending on each other, but they depend on the Libraries and Externals projects. The "Externals" path contains some external DLLs referenced in our Applications and Libraries. The Libraries path contains commonly used libs (UI templates, Helper classes, etc.). They do not depend on each other and they are referenced in the Libraries and the Tools projects. The Tools path contains some helper programs like setup helpers, update web services, etc. Now, there's some major points why I'd like to change this structure: We can't use server builds. It's uncomfortable to manage TFS scrum management with sprints, impediments, etc. with a solution structure like that. Every developer always has access to all projects in the solution. A complete build lasts too long if one accidentally hits [F6] in Visual Studio... What would you change in this solution? How would you break those projects into smaller Solutions, how should those solutions be structured. My first approach would be, to create one TFS project for each Application, Library and Tool. But how can I ensure that e.g. App 2 always contains the newest version of Lib 1? Do I have to monitor changes on Lib 1 and update App 2 manually as soon as the Lib changes? Or can I somehow force Visual Studio to always use the newest version of an external project somehow?

• Depending on fixed version of a library and ignore its updates

  - by Moataz Elmasry

  I was talking to a technical boss yesterday. Its about a project in C++ that depends on opencv and he wanted to include a specific opencv version into the svn and keep using this version ignoring any updates which I disagreed with.We had a heated discussion about that. His arguments: Everything has to be delivered into one package and we can't ask the client to install external libraries. We depend on a fixed version so that new updates of opencv won't screw our code. We can't guarantee that within a version update, ex from 3.2.buildx to 3.2.buildy. Buildy the function signatures won't change. My arguments: True everything has to be delivered to the client as one package,but that's what build scripts are for. They download the external libraries and create a bundle. Within updates of the same version 3.2.buildx to 3.2.buildy its impossible that a signature change, unless it is a really crappy framework, which isn't the case with opencv. We deprive ourselves from new updates and features of that library. If there's a bug in the version we took, and even if there's a bug fix later, we won't be able to get that fix. Its simply ineffiecient and anti design to depend on a certain version/build of an external library as it makes our project difficult in the future to adopt to new changes. So I'd like to know what you guys think. Does it really make sense to include a specific version of external library in our svn and keep using it ignoring all updates?

• What do I need to learn to decide on rename/recompile source package names because of company rebranding?

  - by Roberto Linares

  My company is currently at a rebranding process and the brand names have been used in the sources' package names but these names are only visible to developers who maintain this code so nobody from project management is really interested in changing them considering also that it would imply the recompiling of several old components. What factors do I need to consider when deciding on a change like that? I don't know if I should worry about legal issues or not and if so, how to address this with project management. More background details. I have all the sources and dependencies but since the company rebranding, other development areas have adopted some of the code that needs package name-changing so I cannot take the decision only by myself so I don't make everyone else's code to crash with my core components and I cannot change other areas' code without the permission of those areas' users so yes, my concern is more political than technical. I am going try to coordinate the involved it areas to make the change anyway, since it seems to be the best approach.   Unfortunatelly in my company there's no continuous integration build server so we build our code manually on demand and to get something to production I have to justify the change (even just the package name changing) to QA with an user requirement and some other bureaucratic documentation so that's why I was hesitating the change in first place.

• Calculation of Milestones/Task list

  - by sugar

  My project manager assigned me a task to estimate the development time for an iPad application. Lets assume that I gave estimation of 15 working days. He thought that the number of days where too many and client needed the changes to the application urgently (as in most of cases). So, he told me: "I am going to assign two developer including you and as per my understandings and experience it won't take more than seven working days." Clarifications I was given the task of estimating development time for an individual. How could I be sure that 2 developers are going to finish it within 7 days? (I am new to team & I hardly know the others abilities) Questions Why do most of project managers / team leaders have understandings like: If one developer requires N days, Then two developers would require N/2 days, Do they think something like developer = s/w production machines? Should a team member (developer, not team lead or any higher post) estimate other developers work? I didn't deny anything in the meeting and didn't said, but what should be the appropriate answer to convince them that N/2 formula that they follow is not correct?
