C++窗口编程：显示菜单

C++窗口编程：显示菜单

实现结果：

方法一：

通过CreateWindowsEx函数实现

	HMENU m_hMenu1;
	m_hMenu1 = LoadMenu(GetModuleHandle(NULL), MAKEINTRESOURCE(IDR_MENU1));//IDR_MENU1是你资源文件的菜单ID

    hwnd = CreateWindowEx(WS_EX_CLIENTEDGE, L"WindowClass", L"Carrot", WS_VISIBLE | WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT, 
		CW_USEDEFAULT, 
		720, 
		580, 
		NULL,
         m_hMenu1 
		, hInstance, NULL);

方法二

通过SetMenu函数实现

通过这种方式可以动态设置菜单

	HMENU m_hMenu1;
	m_hMenu1 = LoadMenu(GetModuleHandle(NULL), MAKEINTRESOURCE(IDR_MENU1));
    hwnd = CreateWindowEx(WS_EX_CLIENTEDGE, L"WindowClass", L"Carrot", WS_VISIBLE | WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT, 
		CW_USEDEFAULT, 
		720, 
		580, 
		NULL, NULL 
		, hInstance, NULL);
    
    
	SetMenu(hwnd, m_hMenu1);

方法三

通过WNDCLASSEX类实现

    WNDCLASSEX wc;

	memset(&wc, 0, sizeof(wc));
	wc.style = 0;
	wc.cbClsExtra = 0;
	wc.cbWndExtra = 0;
	wc.cbSize = sizeof(WNDCLASSEX);
	wc.lpfnWndProc = WndProc;
	wc.hInstance = hInstance;
	wc.hCursor = LoadCursor(NULL, IDC_ARROW);
	
	wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
	wc.lpszClassName = L"WindowClass";

	wc.lpszMenuName = L"IDR_MEMU1"; //你的菜单ID
    
    if (!RegisterClassEx(&wc)) { //注册Windows类
		MessageBox(NULL, L"Window Registration Failed!", L"Error!", MB_IConEXCLAMATION | MB_OK);
		return 0;
	}
