D / Bizzare issue playing audio files

« on: June 01, 2014, 07:37:49 am »

Hi, so just as a disclaimer, I am very new to both the D programming language and SFML, so there could easily be a facepalm worthy cause behind my current issue, but if there is I can't find it. I'm currently trying to get a simple test program that uses DSFML to work correctly. Here is my current code:

module winmain;

import core.runtime;
import core.sys.windows.windows;

import dsfml.system;
import dsfml.window;
import dsfml.graphics;
import dsfml.audio;

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    int result;

    try
    {
        Runtime.initialize();
        result = myWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
    }
    catch (Throwable error)             // catch any uncaught exceptions
    {
        MessageBoxA(null, cast(char *)error.toString(), "Error", MB_OK | MB_ICONEXCLAMATION);
        result = 0;             // failed
    }

    return result;
}

int myWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
        void errorMessage(Throwable error)
        {
        MessageBoxA(null, cast(char *)error.toString(), "Error", MB_OK | MB_ICONEXCLAMATION);
        }

    // Load a sprite to display
        Texture texture;
        Sprite sprite;

    try
    {
                texture = new Texture();
                if(!texture.loadFromFile("cute_image.png"))
                        return 0;
                sprite = new Sprite(texture);
    }
    catch (Throwable error)
    {
                errorMessage(error);
        }

    // Create the main window
        auto size = texture.getSize();
    auto window = new RenderWindow(VideoMode(size.x, size.y), "DSFML window");

    // Create a graphical text to display
    auto font = new Font();
    if(!font.loadFromFile("arial.ttf"))
        return 0;
    auto text = new Text("Hello DSFML", font, 50);
        text.setColor(Color.Black);

        // Load a music to play
    try
    {
                auto music = new Music();
                if(!music.openFromFile("nice_music.ogg"))
                        return 0;

                // Play the music
                music.play();
    }
    catch (Throwable error)
    {
                errorMessage(error);
        }

    // Start the game loop
    while(window.isOpen())
    {
        // Process events
        Event event;
        while(window.pollEvent(event))
        {
            // Close window
            if(event.type == Event.EventType.Closed)
                window.close();
        }

        // Clear screen
        window.clear();

        // Draw the sprite
        window.draw(sprite);

        // Draw the string
        window.draw(text);

        // Update the window
        window.display();
    }

    return 0;
}
 

The problem is that while the audio file will load correctly, the program will throw a "Bad file descriptor" error when I actually try to play it. And if that weren't bad enough, when I try to close the program I get the following runtime error:

Unhandled exception at 0x7736A4B9 (ole32.dll) in DSFML_Example.exe: 0xC0000005: Access violation reading location 0xFEEEFEEE.

I really have no idea what's going on here. Looking through my code and configuration, it's not clear at all that I did anything horribly wrong. Here is a link to my entire Visual Studio project in case anyone wants to look at it (it requires you to have Visual D installed).
