What's the best way to achieve a multi-point for an audio converter?

I'm reading this wonderful article on multi-pointness in C# https://rsdn.ru/article/dotnet/CSThreading1.xml and http://rsdn.ru/article/dotnet/CSThreading2.xml And a little lost. There's no way she's going through the C#, and it's easy. Threadand through BackgroundWorkerand through ThreadPool♪ ♪ ♪
Allow me to make an audio converter where the user could choose the number of flows (up to eight) and who would have made progress in the implementation bar. How does C# (NET 4.0) take this?

Thread♪ ThreadPoll and BackgroundWorker are designed to carry out different tasks.
ThreadPool - it's a way to do small, short tasks.
Thread - it's a manual flow class.
BackgroundWorker - it's a way to do it in the background. One It is a long task to reflect its progress on UI.
In your case, it would probably be possible to come in... Tasklaunched with https://msdn.microsoft.com/en-us/library/system.threading.tasks.taskcreationoptions(v=vs.110).aspx ♪ Use https://msdn.microsoft.com/en-us/library/system.threading.cancellationtoken(v=vs.110).aspx to stop them on demand and https://msdn.microsoft.com/en-us/library/hh193692(v=vs.110).aspx to reflect the overall progress of UI.

Your basic idea of conditioning by the name of controller is correct (in my opinion), but the execution can be improved. Use file_helper. php to help perform the task. It is relatively simple: extend the helper in the form indicated https://www.codeigniter.com/user_guide/general/helpers.html?highlight=extending#extending-helpers : Create MY_file_helper.php in application/helpers and put the following inside:if(!function_exists('js_loader')){ /** Carrega os scripts por demanda, a depender do controller ativo e do diretorio definido @return string */ function js_loader() { //Captura a instancia do CI $ci = & get_instance(); //Captura o controller ativo $controller = $ci->router->fetch_class(); //Declara o diretorio onde estao os scripts do $controller. //Este diretorio precisa estar acessivel ao navegador $jsdir = "assets/js/$controller/"; //Checagem do $jsdir if(file_exists($jsdir)){ $DirectoryIterator = new DirectoryIterator($jsdir); echo "\n"; foreach ($DirectoryIterator as $entry) { //Carrega apenas arquivos (exclui diretorios...) if ($entry->isFile()) { //Carrega apenas arquivos '.js' if (in_array($entry->getExtension(), ['js'])) { $file = base_url($jsdir.$entry->getFilename()); echo "<script src='$file' charset='UTF-8'></script>\n"; } } } } } } Press helper in the instance of CodeIgniter (or use) https://www.codeigniter.com/user_guide/general/autoloader.html ) and call the function anywhere view:<?php $this->load->helper('file'); ?> <html> <body> <?= js_loader() ?> </body> </html> Basically: all the .js scripts that are within "assets/js/$controller/" will be loaded when $controller is active.

Always and when vbhtml do not have basic visual code and only contain html you can copy them to a html and they will work without problem.If they have basic visual code then you will need a basic visual support server. .

The error is in:void FixUpdate(){ float h = Input.GetAxisRaw ("Horizontal"); float v = Input.GetAxisRaw ("Vertical"); Move (h, v); Turning (); Animating (h, v); } Unity uses an internal function called http://docs.unity3d.com/ScriptReference/MonoBehaviour.FixedUpdate.html Everything inside it will be called to each frame update. If you use another name, it will think it is another function or method.Just change FixUpdate() by FixedUpdate () The code will look like this:void FixedUpdate(){ float h = Input.GetAxisRaw ("Horizontal"); float v = Input.GetAxisRaw ("Vertical"); Move (h, v); Turning (); Animating (h, v); } *Don't forget to say more details of the tutorial you're doing to make it easy for people who try to take your doubts https://www.assetstore.unity3d.com/en/#!/content/21028

You can use like you well said "Touch", here is a small example from Unity's API:if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) { // touchCount devuelve el número de dedos sobre la pantalla // GetTouch(0).phase devuelve el estado del primer dedo registrado } Just read the API a little bit to find more information about the Touch and their phases. Here are some links from the Unity API that will serve you: https://docs.unity3d.com/ScriptReference/Input-touchCount.html https://docs.unity3d.com/ScriptReference/Input.GetTouch.html Check this out, and if you see that you're not clear yet, I'm trying to help you.[SOLD]private bool isDragging; void Start() { isDragging = false; } void Update() { if (Input.touchCount != 1) { isDragging = false; } if (!isDragging) { // tu código para coger un objeto isDragging = true; } }

I advise you to use replace as cited by the user @Marconi I think it is worth remembering that one thing makes your case very difficult, you want to eliminate several special characters (-,*/&) and leaving some at specific points like in the digits after KM, this makes it very difficult to create a general logic that will solve your problem.But if you want to continue using regex, you can use multiple ORs (|)for the cases, leaving the rarest at the beginning.(\d*\.\d*?|\d*,\d|\w*|\s) The above regex will capture everything you want, it first checks the sequence case being digits followed by . with digits after to satisfy the case (450.00) then checks if the sequence is digit followed by , digit then checks non-special characters cases being tiny or capitalized and then checks if these characters are spaces.

It's a very short waist. There is a so-called flow pool in which the system creates and stores a number of flows. Taska takes a free flow from the pool and performs the task there (sometimes they are not sufficient, but in general, it can be assumed that each casket works in a separate flow). So, when you get the message, you get the flow, it opens the file, it gets the data, the file closes, the flow goes back to the pool.One of the most common problems of such an architecture. If, suddenly, you two users want to record the data in the same file... The system will fall. Because the file is open with one flow, and it's impossible to record it from the other.Plus there are limitations on the file system on the simultaneous recording.A leap of implementation that would be easier (only from my point of view) to turn. And two flows. The first receives data from the network, and puts the team in line, "write that test into that file." The second flow from this queue is burying data and writing files. In this case, you on the one hand are not blocking the program for the file record. On the other hand, you guarantee that all the files will be recorded in the order they've arrived and without conflict.

There is no change in data structure.Standard C++ containers are not safe, once. Even if you make them insecure by surrounding their use of the metex, any operation with a container in one flow has a disability in the other flow, and access to them leads to UB and, at best, to a sin (and at the worst, to memory shooting).You'll have to keep the extra data. For example, NET adopts this approach: when the collection changes, the collection grows. version number data. Reading flux, after having a mythex, can check if the data version has changed, and when you change, throw out your heterans and start bypassing the collection.Well, if you don't mind the collection, fast.You can go to a simpler solution, blocking the entire collection while rounding.

First, you do not need divs/tds to emulate a padding, you can and should use a padding/margin.you can achieve the same result using the following HTML.html, body { position: relative; width: 100%; height: 100%; margin: 0px; padding: 0px; } div { box-sizing: border-box; } #header { position: absolute; top: 0px; height: 30px; width: 100%; background: silver; } #aside-menu { position: absolute; top: 30px; bottom: 0px; left: 0px; width: 34px; background: gainsboro; } #content { position: absolute; top: 30px; bottom: 0px; left: 34px; right: 0px; padding: 0px 10px; overflow: auto; background: whitesmoke; }<div id="header"> </div> <div id="aside-menu"> </div> <div id="content"> <div id="lipsum"> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit.

I don't know if it's the best, but I think you could (a) turn the column type into a b string) then turn the column into a common list c) make a classic join() python to concate each element of the list:cadena = "".join(df.tu_columna.astype(str).to_list())

I think it's easy.First, put it in the 2D-container. Background="Transparent" and sign for messages from mice. ♪ MouseDown You'll get it. two-dimensional The coordinates of the point where your event occurred. You need to find what. three-dimensional The object corresponds, you have to launch a hit test procedure. Beamfrom this point, cross your figures.Use the procedure. VisualTreeHelper.HitTestwhich will " lead " you to the necessary three-dimensional element:void OnMouseDown(object sender, MouseButtonEventArgs args) { Point pos = args.GetPosition(Viewport); PointHitTestParameters pp = new PointHitTestParameters(mouseposition); VisualTreeHelper.HitTest(Viewport, null, OnHit, pointparams); } (name) Viewport That's right. Viewport3D) If your element is not in the 2D oblasts (e.g., this is Viewport3DAnd in the 3D regions, you're gonna need to use three-dimensional parameters that don't an initial point, but also direction:RayHitTestParameters pp = new RayHitTestParameters( new Point3D(mousePoint.X, mousePoint.Y, 0), new Vector3D(0, 0, 1)); Procedure OnHit It looks like,public HitTestResultBehavior OnHit(HitTestResult rawresult) { if (rawresult is RayHitTestResult rayresult) // если это 3D-результат { // то мы попали в какой-то 3D-объект, и можем с ним работать var modelHit = rayresult.ModelHit; // обрабатываем return HitTestResultBehavior.Stop; // остановить поиск } return HitTestResultBehavior.Continue; // продолжить поиск } Literature:Microsoft Docs, https://docs.microsoft.com/en-us/dotnet/framework/wpf/graphics-multimedia/how-to-hit-test-in-a-viewport3d WPF3D Team Blog, https://blogs.msdn.microsoft.com/wpf3d/2009/05/18/3d-hit-testing/ https://github.com/ariesy/WPFSamples/tree/master/HitTest3D/cs (example of annex)

You could do something like this:#include <iostream> using namespace std; enum CellState{ Top = 1, Right = 2, Bottom = 4, Left = 8, Visited = 128, Initial = Top | Right | Bottom | Left }; int main(void){ CellState estado = Top; if(estado & Initial){ cout << "Celda Initial" << endl; }else{ cout << "Celda NOT Initial" << endl; } return 0; } OutcomeCelda InitialWhen carrying out the implementation of the flags in:Top | Right | Bottom | LeftWe can do the extraction of a value different from them using the operator:& - 2005 Just an ampersandTo do this we apply the instruction:if(estado & Initial)Return true as long as the value is different from those of the flag (bandera).

for this type of positioning it is interesting to make use of the flexbox features. In this case, you can, in div which contains the two news apply the following:.barra-vermelha { align-items: center; display: flex; flex-flow: row wrap; justify-content: center; } In this way you guarantee that, the tags that are contained in the div that has the 'red-bar' class, will be arranged next to the other as you wish.

That's why the UseStartup method is generic and expects any kind of class. i.e. you can send an empty class and compile the program, but you will not have configured services or the handling of the request.public static IWebHostBuilder UseStartup<TStartup>(this IWebHostBuilder hostBuilder) where TStartup : class; UPDATEThe UseStartUp method belongs to an IWebHostBuilder extension and its content is as follows:public static IWebHostBuilder UseStartup<TStartup>(this IWebHostBuilder hostBuilder) where TStartup : class { return hostBuilder.UseStartup(typeof(TStartup)); } Which using Reflection gets the type of class sent later calls to:public static IWebHostBuilder UseStartup(this IWebHostBuilder hostBuilder, Type startupType) { var startupAssemblyName = startupType.GetTypeInfo().Assembly.GetName().Name; return hostBuilder .UseSetting(WebHostDefaults.ApplicationKey, startupAssemblyName) .ConfigureServices(services => { if (typeof(IStartup).GetTypeInfo().IsAssignableFrom(startupType.GetTypeInfo())) { services.AddSingleton(typeof(IStartup), startupType); } else { services.AddSingleton(typeof(IStartup), sp => { var hostingEnvironment = sp.GetRequiredService<IHostingEnvironment>(); return new ConventionBasedStartup(StartupLoader.LoadMethods(sp, startupType, hostingEnvironment.EnvironmentName)); }); } }); } Any doubt about ASP's operation can be reviewed https://github.com/aspnet Greetings!
