  • C++ DLL-Linking UnResolved Externals

    - by Undawned
    I have a rather big Core project that I'm working with, I'm attempting to adapt it to use a DLL Engine I've built, I'm getting a bunch of errors like: unresolved external symbol "private: static class When including some of the headers from the Core in the DLL, the class is exported via __declspec(dllexport) but any header with static members throws out a crapload of errors regarding the static members. This is a rather big project, I can't exactly run around removing every static class member I see, is there anyway around this kind of thing?

  • Is there any framework for Windows Forms, DB driven application development/prototyping?

    - by dolzenko
    I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

  • Is it reasonable to use OpenGL for desktop applications?

    - by JamesK89
    I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

  • Web framework recommendation for python (webservices, auth, cache, ...)

    - by illuminated
    Hi all, Googling for the past week, but cannot finally decide which python web framework would be right for me. The web app I'm about to develop would be almost completely "pure" html with js (jQuery). Server side would have to do the following: authentication session management caching web services (almost all the on page data would be pulled with jQuery through web services) secured web services (through some form of authentication; this is for remote accessing some of the web services though other web apps, desktop/mobile applications) If there is a good tutorial/guide/idea for how to do this in Django I would be most thankfull if someone could share it as I already have experience with it. The thing that made me start thinking about other frameworks is Django's built in ORM. I know I could swap it with SQLAlchemy, but wouldn't go down that road if I'm not sure all the rest of the requirements is supported. Thanks all in advance.

  • What is a good CPU/PC setup to speed up intensive C++/templates compilation?

    - by ApplePieIsGood
    I currently have a machine with an Opteron 275 (2.2Ghz), which is a dual core CPU, and 4GB of RAM, along with a very fast hard drive. I find that when compiling even somewhat simple projects that use C++ templates (think boost, etc.), my compile times can take quite a while (minutes for small things, much longer for bigger projects). Unfortunately only one of the cores is pegged at 100%, so I know it's not the I/O, and it would seem that there is no way to take advantage of the other core for C++ compilation?

  • Best way to version control a WCF application with Git?

    - by Sam
    Suppose I have the following projects. The format is [ProjectName] : [ProjectDependency1, ProjectDependency2, etc.] // Service CoolLibrary WcfApp.Core WcfApp.Contracts WcfApp.Services : CoolLibrary, WcfApp.Core, WcfApp.Contracts // Clients CustomerX.App : WcfApp.Contracts CustomerY.App : WcfApp.Contracts CustomerZ.App : WcfApp.Contracts (On a side note, WcfApp.Contracts should not depend on WcfApp.Core, right? Else CustomerX.App would also depend on and thus be exposed to the service domain model?) (CoolLibrary is shared with other applications, so I can't just put it inside of WcfApp.Services.) All of this code is in-house. I was thinking of having 6 repositories for this. The format is [repository folder name] : [Projects included in repository.] 1. CoolLibrary.git : CoolLibrary 2. WcfApp.Contracts.git : WcfApp.Contracts 3. WcfApp.git : WcfApp.Core, WcfApp.Services 4. CustomerX.App.git : CustomerX.App 5. CustomerY.App.git : CustomerY.App 6. CustomerZ.App.git : CustomerZ.App How should I manage my project dependencies? I see three options: I could use binaries which I have to manually copy to each dependent repository. This would be easiest at the start, but my repositories would be a little bloated, and it'd become more tedious as I add more client apps for customers. I could import dependent code as submodules. This is what I will probably end up doing, although I keep reading on the web that submodules are a hassle. I also read that I can use something called the subtree merge strategy, but I am not sure how it is different from just cloning the repo into a subdirectory and adding the subdirectory to .gitignore. Is the difference that the subtree is recorded in the master repository, so (for example) cloning it from a different location will also pull the subtree? I know I asked a lot of questions in this post, but the most important two questions I have are: 1. Am I using the right number and layout of repositories? Should I use less or more? 2. Which of the three dependency management strategies would you recommend? Is there another strategy I haven't considered?

  • Rails + facebox + authlogic - how?

    - by Vitaly
    Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

  • Tomcat startup logs - SEVERE: Error filterStart how to get a stack trace?

Does somebody have a suggestion for how to increase the logging in Tomcat to get stack traces for errors like this?

  • java.lang.NullPointerException exception in my controller file (using Spring Hibernate Maven)

    - by mrjayviper
    The problem doesn't seemed to have anything to do with Hibernate. As I've commented the Hibernate stuff but I'm still getting it. If I comment out this line message = staffDAO.searchForStaff(search); in my controller file, it goes through ok. But I don't see anything wrong with searchForStaff function. It's a very simple function that just returns the string "test" and run system.out.println("test"). Can you please help? thanks But this is the error that I'm getting: SEVERE: Servlet.service() for servlet [spring] in context with path [/directorymaven] threw exception [Request processing failed;

    I have an 'optional' parameter on a method that is a KeyValuePair. I wanted an overload that passes null to the core method for this parameter, but in the core method, when I want to check if the KeyValuePair is null, I get the following error: Operator '!=' cannot be applied to operands of type System.Collections.Generic.KeyValuePair<string,object>' and '<null>. How can I not be allowed to check if an object is null?

  • Can you in any way interface Ruby Gems with PHP, Python, etc.?

    - by Chad Johnson
    Stupid question, and forgive me for asking, but someone is asking me, and I am not a super expert with Rails yet. Suppose I have some Rails gem I write. Now suppose a customer has some other framework, like Django or CakePHP, and I want to provide the functionality offered by my gem (eg. CRUD for automotive data) to them as a module in their framework. Could I somehow make it so they could interface my gem with Django or CakePHP? Obviously I could do something with some API magic--and I'll probably end up going that route. But I just want to know whether there is a way to directly interface with Gems from a non-Rails application.

  • Grails: GGTS not running on Amazon AWS EC2 anyone else successful?

    - by Anonymous Human
    Im just curious if anyone has had success trying to run the Groovy Grails tool suite on an Amazon AWS EC2 instance with its display exported into your windows machine. If so, I wanted to know which flavor of linux was used on the EC2. I am not having much success with it on the Amazon Linux but haven't tried their Ubuntu instances yet. I got all the way to getting GGTS installed and getting the display exported but when I launch GGTS I get log errors about libraries missing. This is most likely because I didn't use yum to install it so I am probably missing dependencies but I didn't have a choice its not offered as a yum package.

  • 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?

  • How can i use a C# dll in a Win32 C++ project ?

    - by Agito
    I am working on a solution, most of its core engine is developed as Win32 C++ (and is Platform independent and is also used on OS X), some time ago we needed to call C++ dll's of core engine from C# and I was able to Load main solution's DLL in C# (by the help of some threads here on SO). but now we have certain things implemented in Managed C# dll and need to use it in Win32 C++ project? (and just function definitions and dll are provided)

  • Why should I use a thread vs using a process?

    - by danmine
    I'm a newbie at this so please forgive me for my ignorance. Separating different parts of a program into different processes seems (to me) to make a more elegant program then just threading everything. In what scenario would it make sense to make things run on a thread vs separating the program into different processes? When should I use a thread? Edit: Anything on how (or if) they act differently with single core and multi core would also be helpful.

  • Manually Increasing the Amount of CPU a Java Application Uses

    - by SkylineAddict
    I've just made a program with Eclipse that takes a really long time to execute. It's taking even longer because it's loading my CPU to 25% only (I'm assuming that is because I'm using a quad-core and the program is only using one core). Is there any way to make the program use all 4 cores to max it out? Java is supposed to be natively multi-threaded, so I don't understand why it would only use 25%.
