| How to render expo-av video taking biggest size while preserving aspect ratio inside a flatlist possible? Posted: 03 Jul 2022 07:49 PM PDT I am developing an instagram-like app where I needed to render images/videos. I am using flatlist to prevent memory lost, and using expo-av package to render the video. Here is a screenshot of what I want to achieve:  So my goal here is to render videos with dynamic sizes. Expand all videos to fit the width of the screen, while preserving its dynamic aspect ratio, and crop rounded edges, However, I am struggling to "expand" the renderItem in a flatlist, but it just doesn't render the component at all but I can still hear the video playing. This is my FlatList: <FlatList style={{ width: "100%", height: "100%", backgroundColor: "yellow" }} data={[0, 1, 2, 3, 4]} keyExtractor={item => item} renderItem={renderItem} />
And my renderItem callback: const renderItem = ({ item }) => { return <Post post={item} />; }
Post item code: export default ({ post }) => { const videoRef = useRef(null); const [status, setStatus] = useState({}); return ( <View style={{ width: "100%", height: "100%", backgroundColor: "blue" }}> <Video ref={videoRef} source={{ uri: 'http://commondatastorage.googleapis.com/gtv-videosbucket/sample/VolkswagenGTIReview.mp4', }} style={{ width: "100%", height: "100%", backgroundColor: "blue" }} resizeMode="contain" autoplay isLooping shouldPlay={true} onPlaybackStatusUpdate={status => setStatus(() => status)} /> </View> ); }
Result (yellow background: flatlist area, post item should appear blue but not showing up):  |
| How to do cleanup in useEffect React? Posted: 03 Jul 2022 07:49 PM PDT Usually I do useEffect cleanups like this: useEffect(() => { if (!openModal) { let controller = new AbortController(); const getEvents = async () => { try { const response = await fetch(`/api/groups/`, { signal: controller.signal, }); const jsonData = await response.json(); setGroupEvents(jsonData); controller = null; } catch (err) { console.error(err.message); } }; getEvents(); return () => controller?.abort(); } }, [openModal]);
But I don't know how to do in this situation: I have useEffect in Events.js file that get events from function and function in helpers.js file that create events on given dates except holidays (holiday dates fetch from database). Events.js useEffect(() => { if (groupEvents.length > 0) { const getGroupEvents = async () => { const passed = await passEvents(groupEvents); // function in helpers.js (return array of events) if (passed) { setEvents(passed.concat(userEvents)); } else { setEvents(userEvents); } }; getGroupEvents(); } }, [groupEvents, userEvents]);
helpers.js const passEvents = async (e) => { try { const response = await fetch(`/api/misc/holidays`, { credentials: 'same-origin', }); const jsonData = await response.json(); const holidays = jsonData.map((x) => x.date.split('T')[0]); // holiday dates return getEvents(e, holidays); // create events } catch (err) { console.error(err.message); } };

| Autocomplete of input field with a lot of data Posted: 03 Jul 2022 07:49 PM PDT I am trying to create a search field, searching for cities in Denmark. I have an API with JSON to get all the cities, but there is a lot of data and therefore it takes time to load the page. Is there any way that I can load data from this API after the user has typed in the field? Here is a snippet of the Javascript/PHP I am using to get the data. Here you can see the link of all the cities too. var cities = []; <? $citiesData = file_get_contents('https://api.dataforsyningen.dk/steder?hovedtype=Bebyggelse&undertype=by'); $cityJson = json_decode($citiesData, true); for ($x = 0; $x <= count($cityJson) - 1; $x++) { ?> cities.push("<? echo $cityJson[$x]["primærtnavn"]; ?>"); <? } ?>
After this I am using the autocomplete Javascript function from W3Schools, which can be found here: https://www.w3schools.com/howto/howto_js_autocomplete.asp How can I make this so it does not take long for the page to load? |
| Login Page with ASP.NET Core (MVC) Posted: 03 Jul 2022 07:47 PM PDT I am trying to learn asp.net core (MVC) , and I am posting this question after trying to implement everything that I could understand from Google. I want to create a simple login Page. I have earlier worked on asp.net framework with ado.net and webforms using edmx, but I learned that edmx and webforms are now outdated. So, I wanted to learn the new method. These are the tables and stored procedure I created create table users(userId int identity(1,1) primary key, username varchar(20), password varchar(20)) create proc login( @username varchar(20), @password varchar(20) ) as begin if exists(select * from users where username = @username and password=@password) select 'Success' as UserExists else select 'Failed' as UserExists end
Then I created the Model Class - public class Login { [Key] public int userId { get; set; } [Required(ErrorMessage = "Username is requried!")] public string username { get; set; } [Required(ErrorMessage = "Password is requried!")] public string password { get; set; } }
Then I added model in my project. I referred this link https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mvc-app/adding-model?view=aspnetcore-6.0&tabs=visual-studio Then referencing the following link, I added my connection string details in appstring.json file - link https://www.c-sharpcorner.com/article/crud-operations-in-asp-net-core-mvc-net-5-0/ "WebsiteContext": "Server=DELL\\SQLEXPRESS01;Database=website;Trusted_Connection=True;MultipleActiveResultSets=true"
This is startup.cs public void ConfigureServices(IServiceCollection services) { services.AddControllersWithViews(); services.AddDbContext<WebsiteContext>(options => options.UseSqlServer(Configuration.GetConnectionString("WebsiteContext"))); }
I created the login.cshtml with basic asp.net. @{ ViewData["Title"] = "Login"; } <h1>Login</h1> <div> <table> <tr> <td> <asp:TextBox ID="username"></asp:TextBox> </td> <td> <asp:TextBox ID="password"></asp:TextBox> </td> </tr> <tr> <td> <asp:Button ID="submit"></asp:Button> </td> </tr> </table> </div>
Now, I am confused as how should I proceed next. Here is my LoginController class. This was generated automatically after scaffolding. public class LoginController : Controller { private readonly WebsiteContext _context; public LoginController(WebsiteContext context) { _context = context; } // GET: Login public async Task<IActionResult> Index() { return View(await _context.Login.ToListAsync()); } // GET: Login/Details/5 public async Task<IActionResult> Details(int? id) { if (id == null) { return NotFound(); } var login = await _context.Login .FirstOrDefaultAsync(m => m.userId == id); if (login == null) { return NotFound(); } return View(login); } // GET: Login/Create public IActionResult Create() { return View(); } // POST: Login/Create // To protect from overposting attacks, enable the specific properties you want to bind to, for // more details, see http://go.microsoft.com/fwlink/?LinkId=317598.

| ActiveMQ Artemis Shared Storage slave fail to start if master is not started Posted: 03 Jul 2022 07:49 PM PDT We have a master/slave setup with the shared storage strategy. We observed that if we start the slave when the master is down, we have the following message: AMQ221032: Waiting to become backup node
And the server does not become live. So it means that the slave requires the master to be up at a given time to become operational. Is this the expected behavior? Is there a way to let the slave become live at startup if the master is down? |

| Trying to insert sass stylesheets inside Shadow Root with LitElement Posted: 03 Jul 2022 07:48 PM PDT developers: This is my first question after so many years as a simple viewer in Stackoverflow. My trouble is: I'm trying to use scss stylesheets with LitElement components, encapsulated into a React project. The webpack config of my repository injects stylesheets in the header of the page (and it's something I can't change due to other projects in my repository), but I find that my ShadowRoot doesn't get the styles from the header (I tried to acceed to :host, :root, shadowroot... from the .scss file, but it never worked), and I realized that, initially, I can select the target I want to append to my stylesheet configuring the style-loader module in my webpack config and sending the target I want to include the stylesheet in with the .use() function, but I guess it only works with HTMLElement component, not with mine witch extends from LitElement. This is my config of module.exports in webpack.config.js: rules: [ { test: /\.css|\.s(c|a)ss$/, include: [ path.resolve(__dirname, 'src/componentsLit/'), path.resolve(__dirname, 'src/pagesLit/'), path.resolve(__dirname, 'src/widgetsLit/'), ], use: [ 'lit-scss-loader', 'extract-loader', { loader: 'style-loader', options: { //injectType: 'lazyStyleTag', insert: function insertIntoTarget(element, options) { var parent = options.target || document.head; parent.appendChild(element); }, }, }, 'css-loader', 'sass-loader', ], }, ], },
This is what I'm trying to render in my component: import { html, css, LitElement } from 'lit-element'; import { nothing } from 'lit-html'; import myStyles from './myStyles.scss'; export class myCustomElement extends LitElement { static get is() { return 'my-customelement'; } static get properties() { return { [...] }; } static get styles() { /*var style = css([require('./myStyles.scss')]); return [style];*/ } constructor() { super(); [...] } firstUpdated() { myStyles.use({ target: this.shadowRoot }); } [...] } customElements.define(myCustomElement.is, myCustomElement);
I get that the function use() is not avaliable for LitElement, and as I see in the style-loader doc, is the way to select where I want to place the <style></style> markdown. Any alternative to insert stylesheets from scss with this configuration? Thanks. |
| VLAN Priority, DEI and ID are missing in UDP Package Posted: 03 Jul 2022 07:47 PM PDT I am building an ethernet simulation project to send and receive UDP packages to an external device (let's call it A). I am supposed to simulate multiple devices, some of them send UDP packages (let's call them B) and some receive UDP packages (let's call them C), B and C are on two different VLANs with two different IDs. I used an external ETH/Adapter for B and C, which both are connected to a switch alongside the main device A (which can see both the VLANs). then I configured the two eth/adp on windows by setting the "VLAN and Priority" to Enabled and Set VLAN ID with the correct ID for each B and C, finally, I set static IPs for each one of them. I then used QT to create the simulation project, The Receiving parts are perfect Device A is transmitting UDP packages to Multicast and I join with VLAN C on the Multicast and start reading these frames. The problem is with sending, I am able to send the frames correctly however the 4 bytes that define the Priority, DEI, and ID are missing (which means device A is not receiving and dumping these frames) You can see in the below screenshot, on the right the healthy packages that are accepted by device A and on the left the simulated frames that are not accepted Comaprison between accepted and unaccepted packages Here is the Code I use to bind and Join Multicast socket_1 = new QUdpSocket(this); qDebug() << "Binding UDP Socket ..." ; bool bind_res = socket_1->bind(QHostAddress("192.168.11.4"), 51011 , QUdpSocket::ShareAddress); if(!bind_res) { qDebug() << "Faild to bind with Error: " +socket_1->errorString() ; QApplication::quit(); } bool join_res = socket_1->joinMulticastGroup(interface->GRP_IP,interface->Qinterface); if(!join_res) { qDebug() << "Failed to join with error: "+ socket_1->errorString() ; QApplication::quit(); } connect(socket_1, SIGNAL(readyRead()), this, SLOT(handleReadyRead())); qDebug() << "UDP Socket initialized successfully ..." ;
and here is the function to send (interface->GRP_IP is the Multicast IP) void UDPSocket_VLAN11::sendUDP_1(QByteArray data) { qint64 res = socket_1->writeDatagram(data, interface->GRP_IP, 50011); qDebug() << " --- Sending UDP Packet ---"; qDebug() << "Sending to: " << interface->GRP_IP; qDebug() << "Sending port: " << port; qDebug() << "Sending Size: " << data.size(); qDebug() << "Sending: " << data.toHex().toLower(); qDebug() << "Sending Result: " << res; }
Can someone please point how to set these values weather it's in the configuration of the VLAN or the socket in QT ? |

| NodeJS concatenate all files in a directory Posted: 03 Jul 2022 07:47 PM PDT Is there a faster or more succinct way to concatenate all of the files located in a directory using NodeJS? In bash I could do something like this: for file in $1 do cat "$file" echo done > $2;
Here is what I'm doing now: var fs = require('fs'); var Promise = require('bluebird'); module.exports = function(directory, destination) { return new Promise((resolve, reject) => { fs.readdir(directory, (err, files) => { if (err) { return reject(err); } (function next() { var file = files.shift(); if (!file) { return resolve(); } fs.readFile(directory + '/' + file, (err, content) => { if (err) { return reject(err); } fs.appendFile(destination, '\n' + content, (err) => { if (err) { return reject(err); } return next(); }); }); })(); }); }); };

| Node JS req.body undefined Posted: 03 Jul 2022 07:49 PM PDT I've looked through quite a bit of other posts and I'm very lost with this. I can run a console.log(req) and get the following output ServerResponse { ... req: IncomingMessage { ... url: '/my-endpoint', method: 'POST', statusCode: null, statusMessage: null, ... body: { foo: 'bar' }, _body: true, ... route: Route { path: '/my-endpoint', stack: [Object], methods: [Object] } }, ...
Looks solid, so I would expect to do console.log(req.body) and get { foo: 'bar' } back in the console...but nope, getting undefined After research, I found that it may be something with my app.js file and specifically with a body-parser, however, I have all of that already var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var http = require('http'); var app = express(); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'pug'); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); //Home Page Rendering var index = require('./routes/index'); app.use('/', index); // All other routes are kept in the `routes` module require('./routes')(app); module.exports = app;
routes.js
module.exports = function routing(app) { var apiClient = require('./services/apiClient'); app.post('/get-device-info', function(err, req, res){ console.log("/get-device-info routes"); apiClient(req, res); }); };
apiClient.js
module.exports = function callApi(req, res){ console.log(req); console.log(req.body) };
index.js
var express = require('express'); var router = express.Router(); /* GET home page. */ router.get('/', function(req, res, next) { res.render('index', { title: 'Express' }); }); module.exports = router;
Here's what I've tried app.use(express.bodyParser());

| Escaping double-quote in `delims` option of `for /F` Posted: 03 Jul 2022 07:48 PM PDT I'm having a bit of trouble with a batch script which needs to parse a value out of an config file into a variable. Suitably anonymised, the relevant line of the file looks like <?define ProductShortName="Foo" ?>
I want to set a variable to Foo. The string ProductShortName is unique enough to get the line with findstr, but then I have to extract the value. The correct approach seems to be for /F, but all of the following give errors: for /F "delims=^" usebackq" %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`) for /F "delims="" usebackq" %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`) for /F "delims=\" usebackq" %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`) for /F 'delims=^" usebackq' %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`) for /F 'delims=" usebackq' %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`) for /F "delims=" usebackq" %%G in (`findstr /L "ProductShortName" "%~dp0Installer\Branding.wxi"`)
mostly along the lines of usebackq" %G in (`findstr /L "ProductShortName" "C:\foo\bar\Installer\Branding.wxi"`) was unexpected at this time.
