Thanks for your hint I didn´t see a button for code tags so i thought they are not available.

General / Access violation with sf/std string

« on: April 24, 2012, 07:49:32 pm »

EDIT: Solved it, I was linking the false DLL files...

Hi i just started SFML yesterday. I wanted to start with the example code for displaying text but if i try to convert a unicode string to a single-byte string and clean up later i get a access violation at _lock. First someone told me it could be the default-font bug it happens only if i use the sf and std string.

Compiler: MSVC 2010
OS: Win-7 32 Bit

Source:

#include <Windows.h>
#include <string>
#include <SFML\Graphics.hpp>

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int CmdShow )
{
        //sf::String sfStr("My Application");
        //std::string Str = sfStr.toAnsiString();

        sf::RenderWindow window(sf::VideoMode(600,400), "");
        //window.setTitle(Str);
       
        sf::Text text("First Time Test Text");

        while(window.isOpen())
        {
                sf::Event event;
                while(window.pollEvent(event))
                {
                        if(event.type == sf::Event::Closed)
                                window.close();
                }
                window.clear();
                window.draw(text);
                window.display();
        }
        return 0;
}

If I uncomment the 3 lines i get a access violation reading at 0x696c7064.
