想做一个3d测试小程序，主要是检测计算机支不支持简单的opengl 3d功能。手头上有一些opengl源代码，但都是控制台的。我想基于vc的单文档界面，测试时弹出一个窗口用来显示动画，限定时间自动关闭此窗口。最好是尽量少的改动已有代码。

我设计的是一个单文档的界面，其中响应菜单函数中直接把控制台程序移植过来，如下 
void CMainFrame::OnGo()
{
        // TODO: 在此添加命令处理程序代码
......
    int argc = 1;
        int wi;
    char *argv[] = {"OpenGL Application"};
        glutInit(&argc,argv);
        glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
        glutInitWindowSize(600,600);  // Size of the OpenGL window
        wi=glutCreateWindow("OpenGL 2 Dimensonal Geometries");        // Creates OpenGL Window                                        
        glutDisplayFunc(display);                
                     glutKeyboardFunc(keyCB);                // set window's key callback 
        glutSpecialFunc(specialKey);        // set window's to specialKey callback
        glutMainLoop();
//
}

程序编译通过，函数能响应，也按预想的弹出一个新窗口在其中作图。现在问题是怎么限定时间关闭此窗口，而且如果手动关闭的话会引起中端错误

哪位若能提供比较好的建议或方法，不胜感激。
