First, I created an old OpenGL context to load OpenGL extensions. After that, I tried to create a new OpenGL context, but function 'wglCreateContextAttribsARB' threw error code 0xC007000D. So I locked where the error was and I saw glewInit is the function which throws the error code 0x0000007F, but glewInit returns GLEW_OK, which means that there was any error in glewInit...
