vector 2 (2 values from -1.1)

Demir last edited by

Physics2D. Raycast accepts vector2 to indicate the direction up to 0.1, down 0, -1 to right 1, 0, and left -1, 0 How can I transform it.Rotation.z in Vector2, to make the beam look the same place as the object, Vector2.down will always be driving the beam down, regardless of the turn of the object.

// перевод градуса в радиану
float radian = transform.Rotation.z*Mathf.Deg2Rad;
Vector2 vector = new Vector2(Mathf.Cos(radian), Mathf.Sin(radian));

Without knowing the geometry of the circumference, you won't go far in the gheimde. What? Sin♪ Cos and Pi I need to know.

Well, if I understood right, you want to call forms and put them as children of the MDIParent FormCaller. I did something similar, but before we put some points...The way you're suggesting: caller.CallForm(anotherForm), requires the class FormCaller "know" all forms that will be invoked. See if I can help you extract some idea from the implementation below...To solve the problem, I had created a class/enumeration only to describe the child forms of the MDI, but the maintenance was very constant. I then decided to change strategy and create a pattern that could be reused by any other MDIParent.I created an interface that forces every MDIParent to know how to invoke their children (in my case, by index);I implemented the interface in an abstract class that would perform the desired patterns (in this case, invoke forms);Inherit the abstract class in any target MDIParent.Something like:public interface IMdiContainer { Form GetCurrentForm(int currentStep); } public abstract class MdiContainerBase { private IMdiContainer _container; protected int index; public MdiContainerBase(IMdiContainer container) { _container = container; } protected override void OnShow(EventArgs e) { base.OnShow(e); // Call mdiChild from mdiContainer ShowMdiChild(_container.GetCurrentForm(index)); } protected override void NextForm() { ShowMdiChild(_container.GetCurrentForm(++index)); } protected override void PrevForm() { ShowMdiChild(_container.GetCurrentForm(--index)); } private void ShowMdiChild(Form form) { form.MdiParent = this; form.Show(); } // and so on... } public class MyCustomMdiContainer : MdiContainerBase, IMdiContainer { public MyCustomMdiContainer() : base(this) { } // implementation forced by interface public Form GetForm(int index) { switch(index) { case 1: return new Form1(); case 2: return new Form2(); default: return null; } } } So you can create everything you need in the interface... You just need to create the switch... I hope I have helped somehow

cv2.inRage only returns a value, in this case the segmentation mask obtained by applying both thresholds. Try a single return value:mask = cv2.inRange(framedit, rojo_bajo, rojo_alto) cv2.imshow("Mask", mask)

Do it the following way, add the ngModel. <select *ngIf="car" class="form-control" [(ngModel)]="selectedDoor" #selectDoor (change)="getRecDet(selectDoor.value);" required > <option *ngFor="let oneDoor of car.doors" [ngValue]="oneDoor"> {{oneDoor.position}} </option> </select> selectedDoor is a Door-type object, since the option for "default" (preselected), can be an object without value, but debe to be of the same type as the Value.[value]="..." - PHPOnly supports Strings.[ngValue]="..." - 2005 Supports any Object - Needs a ngModelRemember: add to your module import { FormsModule } from '@angular/forms';

In this case, you do not want to create a vector that receives 5 values, but rather create a vector with the 5 desired values.To use the syntax similar to what you want, the important thing is to see how https://se.mathworks.com/help/matlab/math/creating-and-concatenating-matrices.html#f1-85254 works and work with him.Operator : :When you need a sequence, it works in two waysa=1:3; %passo default (=1), saída > a=[1 2 3] a=1:2:3; %valor do passo selecionado , saída > a=[1 3] If you need a negative step (even if =1), it is necessary to declare the step:a=3:-1:1; %valor do passo selecionado , saída > a=[3 2 1] In your case: You have two simple options using : :tot=1/2; xi=(1:5)*tot; % OU xi=tot:tot:(tot*5); %ambos tem a mesma saída: xi= 0.5000 1.0000 1.5000 2.0000 2.5000

But two references to the same lines given to the object do not match.Because operators are not virtual, but defined at the compilation stage by type. If you made a transformation object Then the operator will be called. ==which simply compares the references, and they are not equal. False♪class Program { const string S1 = "123"; const string S2 = "123"; static void Main(string[] args) { var s1 = Console.ReadLine(); // 123 var s2 = Console.ReadLine(); // 123 // вызывается оператор сравнения строк Console.WriteLine(s1 == s2); // True // вызывается оператор сравнения объекта, // т.к. это один и тож же то ссылки равны Console.WriteLine(s1 == (object)s1); // True Console.WriteLine(s2 == (object)s2); // True // вызывается оператор сравнения объекта, // т.к. это разные объекты то false Console.WriteLine(s1 == (object)s2); // False Console.WriteLine((object)s1 == (object)s2); // False // тут тоже сравнение объектов, но оно равно, // т.к. это оптимизация компилятора и рантайма, // происходит интернирование строк и создается только // один объект в памяти Console.WriteLine((object)S1 == (object)S2); // True } } It's also possible to look at the compiled code: https://sharplab.io/#v2:EYLgxg9gTgpgtADwGwBYA0AXEBLANgHwAEAmARgFgAoEgBipIAJDSB2Kgbyoe4cgDsAzhiakaDAMqkGAXgYAiUsQDMcgNxUuPfkJFjxxGfMUr1lTd2ZImKBgFkAhtj4AKZjQDaAXQb2oAcwEASnMGTkoeCIYAN18GASlZAGEIQQhcGAA6ACUYewATABknGGdA1QYAegqGYxCImKg4gySUgTTMnPyivhKyyura8MiLUgBOZ3iZWQFiPqqGABUoAFcYOp5mccnpWWcIYAArGDAMQPi56qXV9ZGt5t39o5Oz2fL5q7Wh4c2JhIfD46nGYXBgAMXsuAEn2Gt2cewBz22/yeQNe/TBEKhNxE43hKMCkimDDxgIJaPeK2hPAAvlRqUA=== Where the comparison operator is to be seen.

No. The maximum that can be done is a Regex that validates the format of the text placed to the phone. For example, this below validates the following formats with country code, DDD and phone with 8 or 9 digits +XX (XX) XXXX-XXX or +XX (XX) XXXXX-XXXXX/^(?:\+)[0-9]{2}\s?(?:$)[0-9]{2}(?:$)\s?[0-9]{4,5}(?:-)[0-9]{4}$/ An example of how to use this Regex:var regExp = /^(?:\+)[0-9]{2}\s?(?:$)[0-9]{2}(?:$)\s?[0-9]{4,5}(?:-)[0-9]{4}$/; var telefone = '+55 (55) 23321-5454'; var resultado = regExp.test(telefone); (retorna true ou false)

To achieve that you want you can make use of the event handlerAppDomain.CurrentDomain.UnhandledException This event is invoked when an uncontrolled exception occurs in our application, so it allows us to capture this exception and if you want to save information from it, without our application being "red", that is to say theoricamente occurs an exception, we capture it, show a personalized message, save a trace of error, and our application will continue to work.For this I propose you believe a new class, for example:static class Excepciones { static public void UnhandledException(object sender, UnhandledExceptionEventArgs e) { MessageBox.Show("Ha ocurrido una excepción inesperada.\nContacte con el administrador de la aplicación.", "Excepción", MessageBoxButtons.OK, MessageBoxIcon.Warning); } } To capture the message, or any attribute of the Exception you can do the following (I don't do it in the code I put you)((Exception)e).Message//Quiza podrias mostrar un mensaje con esta informacion. What we do here is a class that will have a status method with the signing of the methods that can accept the event UnhandledException, i.e. a type parameter object and other type parameter UnhandledExceptionEventArgs.Once we've done this we're going to Program.cs And we put the following:AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(Excepciones.UnhandledException); Application.SetHighDpiMode(HighDpiMode.SystemAware); //Este codigo es tuyo lo puse pq tu lo tenias puesto Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Principal()); The first lineAppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(Excepciones.UnhandledException); He's gonna put us in the event that handles the exceptions the method we previously did.Ojo Yeah. namesapce where you declare the class Exceptions is different from the file Program.csYou should add it by means of a using, that is to say in the file Program.cs hypothesically weighty:using namespaceExcepciones; Ojo if you run your project from the visual studio they will continue to release exceptions as they are in the development environment, to verify that you control the exceptions correctly you must execute the .exe of your application.Another way to do the above would be to use the event handler Application.ThreadException, even both can live together, as they all have their pros and cons, if you want you can investigate their differences on the internet.It works practically as the event handler explained above.Your class Exceptions That would be the case.static class Excepciones { static public void ThreadException(object sender, ThreadExceptionEventArgs e) { MessageBox.Show("Ha ocurrido una excepción inesperada.\nEspere unos segundos y vuelva a intentarlo.\nEn caso de persistir el error contacte con el administrador de la aplicación.\n\n*Causa más probable: fallo en la conexión a la base de datos.", "Excepción", MessageBoxButtons.OK, MessageBoxIcon.Warning); } } We also define a method that has the same signature as the event handler ThreadException, i.e. this method will have two parameters, one type object and another type ThreadExceptionEventArgs. This method also shows a message that an exception has occurred.And in the Program.cs Let's go.Application.ThreadException += new ThreadExceptionEventHandler(Excepciones.ThreadException); It's practically the same as the other and you can even use both at once.

My fries don't support a password connection, but only through the clave (keyboard-interactive), so I'm going into a little different.So the console could be too tight. xterm code managers, we need to prepare it.Support structures and Win API[Flags] public enum ConsoleOutputMode : uint { EnableProcessedOutput = 0x0001, EnableWrapAtEolOutput = 0x0002, EnableVirtualTerminalProcessing = 0x0004, DisableNewlineAutoReturn = 0x0008, EnableLvbGridWorldwide = 0x0010, } public enum ConsoleStdHandle : int { StandardInput = -10, StandardOutput = -11, StandardError = -12 } internal static class NativeMethods { [DllImport("kernel32.dll")] public static extern IntPtr GetStdHandle(ConsoleStdHandle nStdHandle); [DllImport("kernel32.dll")] public static extern bool GetConsoleMode(IntPtr hConsoleInput, ref int lpMode); [DllImport("kernel32.dll")] public static extern bool SetConsoleMode(IntPtr hConsoleInput, int dwMode); } And that's the code.class Program { static void Main(string[] args) { SetupConsoleOutput(); var authMethod = new KeyboardInteractiveAuthenticationMethod("aepot"); authMethod.AuthenticationPrompt += AuthMethod_AuthenticationPrompt; ConnectionInfo connectionClient = new ConnectionInfo("aepot.ru", "aepot", authMethod); using SshClient client = new SshClient(connectionClient); client.Connect(); ReadTop(client); Console.WriteLine("Done."); Console.ReadKey(); } private static void SetupConsoleOutput() { Console.OutputEncoding = Encoding.UTF8; IntPtr handle = NativeMethods.GetStdHandle(ConsoleStdHandle.StandardOutput); int mode = 0; NativeMethods.GetConsoleMode(handle, ref mode); mode |= (int)ConsoleOutputMode.EnableVirtualTerminalProcessing; NativeMethods.SetConsoleMode(handle, mode); } private static void ReadTop(SshClient client) { using ShellStream s = client.CreateShellStream("xterm", (uint)Console.WindowWidth, (uint)Console.WindowHeight - 1, 0, 0, Console.WindowWidth * (Console.WindowHeight - 1)); Console.Clear(); s.DataReceived += S_DataReceived; s.WriteLine("top 1"); Console.ReadKey(true); s.DataReceived -= S_DataReceived; s.Write("\x003"); // Ctrl+C } private static readonly Stream _stdOut = Console.OpenStandardOutput(); private static void S_DataReceived(object sender, ShellDataEventArgs e) { _stdOut.Write(e.Data); } private static void AuthMethod_AuthenticationPrompt(object sender, AuthenticationPromptEventArgs e) { foreach (AuthenticationPrompt prompt in e.Prompts) { Console.Write(prompt.Request); prompt.Response = ReadPassword(false); } } // чтение пароля с клавиатуры private static string ReadPassword(bool displayAsterisk = true) { StringBuilder sb = new StringBuilder(); ConsoleKey key; do { ConsoleKeyInfo keyInfo = Console.ReadKey(true); key = keyInfo.Key; if (key == ConsoleKey.Backspace && sb.Length > 0) { if (displayAsterisk) Console.Write("\b \b"); sb.Length--; } else if (!char.IsControl(keyInfo.KeyChar)) { if (displayAsterisk) Console.Write("*"); sb.Append(keyInfo.KeyChar); } } while (key != ConsoleKey.Enter); Console.WriteLine(); return sb.ToString(); } } Consoli data are updated in real timelast pid: 35258; load averages: 0,41, 0,30, 0,27 up 139+15:00:15 14:40:24 50 processes: 1 running, 49 sleeping CPU: 0,2% user, 0,0% nice, 0,2% system, 0,0% interrupt, 99,6% idle Mem: 39M Active, 1365M Inact, 96M Laundry, 327M Wired, 95M Buf, 136M Free Swap: 4096M Total, 521M Used, 3575M Free, 12% Inuse PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 2732 mysql 47 20 0 935M 37M select 0 416:22 0,22% mysqld In fact, the conclusion to the console holds even color in the console.

Function rank He can do what you need. For example# genero un vector de 20 números de una distribución normal x <- rnorm(20) # los rangos son rank(x) # k menores valores de x son x[rank(x) <= k] # una función que haga eso mi_rango <- function(x, k) {x[rank(x) <= k]} # ejemplo y <- rnorm(100) mi_rango(y, 10) As a task, you can make the function return a list with the lower k values of and but ordered less to greater along with the original posting rates, etc...

If you take your DateTime variable and make a ToString in it by passing the hours format with the letter "H" capital, will already appear in the format of 00 hours.Format "HH" capital appears in the format 24 hours. Tiny "hh" format appears in 12 hours AM/PM format.Example:DateTime data = new DateTime(2018, 06, 29, 00, 11, 49); Console.WriteLine(data.ToString("HH:mm:ss"));

I already found the solution of the problem...After publishing here, I continued to search the internet for the solution of the inconvenience and is the following. ..I ran the App from Visual Studio 2017 to install on the device (in my case it was a tablet), then I stopped the VS debug and uninstalled the App...after that I went to the PC where the Visual Studio 2015 is installed and executed the solution again, this time without any problem. ..The reason I did not find the problem, what I deduce is that there are compatibility errors between the versions of Xamarin or SDK between both Visual Studio, since the 2017 version is integrated with Xamarin and for the 2015 version you have to install it separately.Thanks to all those who took the time to read the publication.
