SFML library : strange error

Question

I'm learning SFML library and i picked a code from the tutorial. it opens a window and it should make me able to close it again but when i close it it says

Debug Error!
Run-Time Check Failure #2 - stack around variable 'App' was corrupted.

and then the console stops working.
this is my code:

int main()
{
    // Create the main window
    sf::Window App(sf::VideoMode(800, 600, 32), "SFML Events");

    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();

            // Escape key : exit
            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
                App.Close();
        }

        // Display window on screen
        App.Display();
    }

    return EXIT_SUCCESS;// = return 0
}

linking to the debug libraries are

sfml-system.lib
sfml-window.lib
sfml-system-d.lib//these are debug files
sfml-window-d.lib

if i ramove the first 2 and built my program it doesn't give errors but when i open it it says :

the application was unable to start correctly (0xc0150002). click ok to close the application

i have a 64 bit computer. and in microsoft vc++ 2010 i can do build solution or debug and i always do build solution.

and i am building in release mode but i have also tried both and they both didn't work

could someone please tell me what i could do to prevent this from happening or how this comes.

If you build a debug version, why not run it in the debugger? At least you will see where the problem is. — Some programmer dude
Besides, should you really call App.Display all the time? In most other frameworks you tell the app object to display once, before entering the main event loop. Also, won't this try to display the window again after it been closed, thereby giving you your problem? — Some programmer dude
I think you need to build SFML specifically for VS2010, the delivered libs don't really work. — Xeo
@JoachimPileborg ,xeo got it ,i had to put my DLL's in the debug file next to my .exe file is it worthy to make this answer or shoul i remove the question — NullPoiиteя

For these application startup issues,it is always a good idea to check if all dlls in the dependency closure are accessible - that is, are they all in the search PATH? We usually use dependency walker to check which dlls are missing, or use gflags for runtime diagnostic

While put your dlls with your exe in same folder works, it does not scale well, one way I usually do is put the library path in PATH environment variable.

And one thing to notice, sfml comes with prebuilt binrary for vs2005 and vs2008, as you are using vs2010, the underlying c runtime library(msvcrt) is different, there would be potential problems - you would better build sfml from source yourself using vs2010 or use vs2005/vs2008, just to be consistent
