Thread: Wm_close & Wm_destroy

What's the difference between them?

here's a part of example in my tutorial :

switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}

can I change it to:

switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
