  • How to free static member variable in C++?

    - by user299831
    Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

  • Using Session Vars in a MVC Domain Model library

    - by 104286623826380127552
    Hello to all. I have a IQueryable function. In that function, I need to store and retrieve data to Session; can you guys point me in the right direction. I've looked at the HttpSessionStatBase where the session is usually taken from HttpContext.Current but this doesnt seem possible to do in the library. Am I missing something? Thanks in advance.

  • local file access with javascript

    - by Jared
    is there any local file manipulation that's been done with javascript? i'm looking for a solution that can be accomplished with no install footprint like requiring AIR. specifically, i'd like to read the contents from a file and write those contents to another file. at this point i'm not worried about gaining permissions, just assuming i already have full permissions to these files.

  • Can I Force A ASP.Net Website to Show Time in A Specific Time Zone?

    - by KevDog
    I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch. I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).

  • MVC alternatives: examples of MVA & AVC?

    - by Phillip Oldham
    I'm interested in learning about the alternative patterns to Model-View-Controller, specifically the Model-View-Adapter and Application-View-Controller patterns. Google results tend to be either a high-level overview or Java-based. Can anyone either provide, or point me to, an example of these patterns in either PHP, Python or JavaScript?

    Hello there, I have my WCF Service hosted in Windows Service. The client application is a website project to which I added the Service reference.

  • SEO Friendly URLs where the phrase used may change in Rails

    - by Newy
    Say I have http://www.mysite.com/I-Like-Cheeseburgers and I want that to point to Item with id 3. Sometime later, I change the name of the item, and now its http://www.mysite.com/I-Like-Hamburgers (and perhaps many more times). I want all these URLs to remain pointing to Item 3. Is it efficient to simply keep a table of [strings,item_ids] and do a lookup on this? Is there a better way?

  • How do I define a foreign key that points to a class of a different name in ActiveRecord with Rails?

    - by Mark
    Hi there, I have a model Follow that defines a user_id and a followed_user_id. If you've used Twitter, this should make sense. I'm trying to make followed_user_id point to a User model, so I can access the user that is being followed through f.followed_user (in the same way that if I have an Entry with belongs_to :user and a user_id column I can use entry.user to get the user.) How can I do this? Thanks!

  • Can you view XAML as "regular" .net code (c#\vb.net)?

    - by cody
    There are times when I find some example XAML that I want\need to do in code (c#\vb.net). I assume at some point the XAML becomes code, or at least IL. So my questions: Am I correct in assuming that XAML is converted to IL? (or if not IL what does it become?) If the above is correct, when does XAML become IL (or whatever it becomes)? Is there some way to see the XAML in as "code" Thanks.

    - by xarzu
    What are the limits of writing a C# app when you want a truly impressive GUI? At what point does one have to leave Visual C# behind and go into WPF? Also, if I choose to go with WPF, do I have to ditch the Visual Studio IDE and go with Expression Studio?

  • Problem with displaying usernames in my flash[:notice] - Agile Web Development With Rails - Chapter

    - by Lee
    I can't figure out what I'm doing wrong here. I can’t seem to get the #{@user.name} to work in my flash[:notice] Everything else works just fine I can add new users, but when I add a new user instead of saying “User John Doe was successfully created”, it says “User #{@user.name} was successfully created.” I'm at this point in the depot app: depot_p/app/controllers/users_controller.rb to work.

  • How do I tell cmake not to create a console window?

    - by user198729
    I can achieve this by gcc : gcc -mwindows -o simple simple.c But only find this in cmake: add_executable(simple WIN32 simple.c) But it's not exactly the same as -mwindows, this will require the entry point to be WinMain, while gcc -mwindows doesn't require this(can be main). How should I do it properly?
