Closing window returns error.

[andrewhopps]

When closing the window, I get an error code: -1073741819. What is going on here and how do I fix it? (Win7, CodeBlocks12.11, SFML2.0)

#include <SFML/Graphics.hpp>

int main()
{

    sf::Texture pTexture;

        std::cout << "Error: Could not locate the font file." << std::endl;

    if(!pTexture.loadFromFile("Player.png"))
        std::cout << "Error: Could not load player image." << std::endl;

        while (window.pollEvent(Event))

        }

        source.x++;

        if(source.x * 32 >= pTexture.getSize().x)
            source.x = 0;

        {

            playerImage.move(0, -10);
        }
        else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
        {
            source.y = Down;
            playerImage.move(0, 10);
        }
        else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
        {

switch(Event.type)
{
case sf::Event::KeyPressed:
    if(Event.type == sf::Event::Closed || Event.key.code == sf::Keyboard::Escape)
        window.close();
    // ...
}

This would translate into: When the event type is KeyPressed, then check whether the event type is Closed OR if the key code is Escape.
As you see the event type can never be KeyPressed AND Closed, thus when you click the X, nothing happens.

As for why it crashes when you press Escape, I'm not really sure...

Well I fixed the above and now both the escape key and the red X close the program. The error code still exists of course. *Code updated above*

Not sure if the same as your problem but I found with Code::Blocks after a run an app, if I 'X' close the console window thats open it gives me an error code like yours.  If i 'press any key' on the console to have it close that way it closes fine.  Codeblocks just doesn't like the console debug window being 'x' closed.

While helping with another issue, Foaly provided me with a full main.cpp and it changed the window handling to as follows, and it works with no error!

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape)
                window.close();
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::P)
            {
