OpenGL code doesn't show anything in window mode - c++

Question

I wanna create a program with OpenGL in my PC. I use this code
#include "stdafx.h"
#include <GL/glut.h>
bool bFullsreen = false;
int nWindowID;
void display(void)
{
//Clear all pixels
glClear(GL_COLOR_BUFFER_BIT);
//draw white polygon (rectangle) with corners at
// (0.25, 0.25, 0.0) and (0.75, 0.75, 0.0)
glColor3f(1.0,1.0,1.0);
glBegin(GL_POLYGON);
glVertex3f(0.25, 0.25, 0.0);
glVertex3f(0.75, 0.25, 0.0);
glVertex3f(0.75, 0.75, 0.0);
glVertex3f(0.25, 0.75, 0.0);
glEnd();
// Don't wait start processing buffered OpenGL routines)
//glFlush();
glutSwapBuffers();
}
void init(void)
{
//select clearing (background) color
glClearColor(0.0, 0.0, 0.0, 0.0);
//initialize viewing values
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}
void keyboardFunc(unsigned char key, int x, int y) {
switch (key) {
case 'f':
bFullsreen = !bFullsreen;
if (bFullsreen)
glutFullScreen();
else {
glutSetWindow(nWindowID);
glutPositionWindow(100, 100);
glutReshapeWindow(640, 480);
}
break;
}
}
void idleFunc(void) {
glutPostRedisplay();
}
int _tmain(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitWindowSize(250,250);
glutInitWindowPosition(100,100);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
nWindowID = glutCreateWindow("Hello World");
init();
glutDisplayFunc(display);
glutKeyboardFunc(keyboardFunc);
glutIdleFunc(idleFunc);
glutMainLoop();
return 0;
}
when i run it in my PC it coesn't show anything and only show background. like this picture:
But when I switch to FullScreen mode, it shows correctly. I searched about it and I found changing GLUT_Single to GLUT_DOUBLE and glFlush() to glutSwapBuffers() but it doesn't work for me.
I have windows 10 with NVIDIA GForce 7300 LE. when I run my program in other PC it runs correctly. so
What is my problem? Is it about my graphic card or my code is incorrect? and
How can I fixed it?
