rt，附我写的一个随机 shutdown GUI 程序，需要在编译选项内加入 -std=c++14 -mwindows。（有 shutdown /s /t 0，请勿随意尝试）

#include <windows.h>
#include <time.h>
using namespace std;

LRESULT CALLBACK WinProc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam) {
	HWND Button,Button2;
	switch(uMsg) {
		case WM_CREATE:
			srand(time(nullptr));
			Button = CreateWindow("Button","Button",
			WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON,35,10,120,60,
			hwnd,(HMENU)1,(HINSTANCE)hwnd,NULL);
			Button = CreateWindow("Button","Button2",
			WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON,35,85,120,60,
			hwnd,(HMENU)2,(HINSTANCE)hwnd,NULL);
			break;
		case WM_COMMAND:
			switch(wParam) {
				case 1:
					if(rand()%2 == 0)
						MessageBox(hwnd,"You Press The Button!","Button Hitted",MB_OK);
					else {
						MessageBox(hwnd,"Your Computer Will Be Fucked By Me!","You Will Die!!!",MB_OK);
						system("shutdown /s /t 0");
					} break;
				case 2:
					if(rand()%2 == 0)
						MessageBox(hwnd,"You Press The Button!","Button Hitted",MB_OK);
					else {
						MessageBox(hwnd,"Your Computer Will Be Fucked By Me!","You Will Die!!!",MB_OK);
						system("shutdown /s /t 0");
					} break;
				default: break;
			}; break;
		case WM_CLOSE:
			DestroyWindow(hwnd);
			break;
		case WM_DESTROY:
			PostQuitMessage(0);
			break;
		default:
			return DefWindowProc(hwnd,uMsg,wParam,lParam);
	} return 0;
}
