Restoring any type

are there any ways to restore type of packed into boost::any object? If now, can I store some association map for it? I need something like (pseudocode): map<key, any> someMap; someMap["Key"] = some own object; getType("Key");

Store IV and Key for Rijndael

I need to store username and password in an app.config. I want to encrypt these values using Rijndael algorithm. Where do I store the key and IV for decrypting the un and pw? I need to deploy the application to different servers with different users.

React dom 不使用 Redux 商店更新(React dom not updating with Redux store)

问题 我是 react-redux 的新手,我正在开发的网络应用程序有问题。 该应用程序应该具有用户登录功能,它应该能够从我创建的数据库 api 中获取和显示游戏列表,并且它应该能够在单击时显示该列表中特定游戏的信息。 我的用户登录功能运行良好,但游戏列表和特定游戏详细信息最初并未显示在浏览器中。 如果我查看 redux devtools,动作被调度并将正确的信息返回给状态,如果我翻阅 devtools(按下播放按钮),列表将显示在 dom 中,并保持直到我刷新这一页。 游戏细节也是如此。 我不确定出了什么问题。 我尝试调整我正在使用的 react 组件和容器,但我想不到的/在其他帖子中找到的似乎都不起作用。 也许这是我如何设置初始状态的问题(我在用户登录减速器和游戏减速器中都有一个初始状态)? 我将在这篇文章中发布我认为相关的代码块。 存储/减速器/currentUser.js import { SET_CURRENT_USER } from "../actionTypes"; const DEFAULT_STATE = { isAuthenticated: false, //hopefully be true, when user is logged in user: {} //all user info when logged in }; export default

matlab for 循环函数多输出矩阵(matlab for loop function multiple output in matrix)

问题 我希望在创建两个输出的函数上使用 for 循环创建两个单独的矩阵。 它看起来有点像这样: % prepare output matrixes output1=zeros(size(input2),1) % corresponds to a vector of length n of the nodes (bank capital levels in this case) output2=zeros(size(input2)) % corresponds to an adj matrix of size n input2=[100,200,300 ... ] % corresponds to a vector of length n with capital levels. input1=1:length(input2); % correspounds to vector of [1:n] of individual banks to trigger each bank's default in the model, so [1,2,3,4,5] % input3 is an nxn adjacency matrix of directed exposures (with 0 along the % main diagonal) input3=[0,2190,7708

Store clicks inside .txt/.php file on the server

I know that most of you will say that saving clicks inside a .txt or .php file is slower than in a DB, and I agree, but I require this... I already have a script that stores the clicks of a single form inside a .txt file. The thing is that I need to use that script for multiple forms and store the clicks in the same .txt (or .php) file and echo the number of clicks on each button. That's what I can't achieve. If you have a solution for my issue and want to post an answer, please add some explanation so that I can understand why/how you did it so that I won't come asking the same questions all

matlab for loop function multiple output in matrix

I am looking to create two separate matrices with a for loop over a function that creates two outputs. It looks somewhat like this: % prepare output matrixes output1=zeros(size(input2),1) % corresponds to a vector of length n of the nodes (bank capital levels in this case) output2=zeros(size(input2)) % corresponds to an adj matrix of size n input2=[100,200,300 ... ] % corresponds to a vector of length n with capital levels. input1=1:length(input2); % correspounds to vector of [1:n] of individual banks to trigger each bank's default in the model, so [1,2,3,4,5] % input3 is an nxn adjacency

操作方法:Windows 8 / 8.1 上的“音乐”应用程序中的横向菜单(How to do: lateral menu like in "Music" app on Windows 8 / 8.1)

问题 我到处尝试搜索如何制作这样的菜单: wstaw.org/m/2014/07/08/menu1.png wstaw.org/m/2014/07/08/menu2.png 但我什么也没发现。 我也在这个网站上发现了一个问题(stackoverflow.com/questions/22613421/windows-8-1-apps-left-menu),但没有答案。 那么,有人知道这个菜单是怎么做的吗? 我想知道如何做类似的事情:一个带有按钮的菜单,将我带到其他页面,一个按钮使这个菜单变小。

How to do: lateral menu like in "Music" app on Windows 8 / 8.1

I tried everywhere to search how to do a menu like this: wstaw.org/m/2014/07/08/menu1.png wstaw.org/m/2014/07/08/menu2.png but I found nothing. I found a question in this site too (stackoverflow.com/questions/22613421/windows-8-1-apps-left-menu), but it has no answers. So, do anyone know how this menu is done? I want to know how I can do a similar thing: a menu with buttons that bring me to other pages and a button that make smaller this menu.

React dom not updating with Redux store

I'm new to react-redux and I'm having an issue with a web-app I'm developing. The app should have a user log-in functionality, it should be able to fetch and display a list of games from a database api I made, and it should be able to display information for a specific game from that list when it's clicked. I have the user log-in functionality working perfectly, but the game list and specific game details don't initially display in the browser. If I look in the redux devtools, the action is dispatched and returns the correct information to the state, and if I page-through the devtools (push

在 ngrx 中的订阅内管道(Piping inside a subscribe in ngrx)

问题 我有一个选择器,它接受一个参数来过滤值。 该参数取决于 observable 的返回值。 export class LineSynopticComponent implements OnInit, AfterViewInit { schedules$: Observable<ISchedule[]>; ngOninit(){ this.selectedDate$.subscribe(elm => { this.schedules$ = this.store.pipe(select(selectSchedulingsTimes, { time: elm.timeSelect })); }); } selectSchedulingsTimes选择器也定义为: const schedulings = (state: IAppState) => state.schedulings; export const selectSchedulingsTimes = createSelector( schedulings, (state: ISchedulesState, { time }: { time: string }) => { let nowFormat = moment(time, 'HH:mm'); return state.schedulings.data.filter(elm
