JOSE HERRADA's questions

I'm practicing C# and in an API object it doesn't let me add a new data to the array

error CS0021: Cannot apply indexing with [] to an expression of type 'Array'

public class UsersController : ControllerBase
{
    private Array people = new object[] {
       new Person { id=1, Name="Ana", age=24 },
       new Person { id=2, Name="Joseph", age=20 } 
    };

    [HttpGet("users")]

    public ActionResult<Person> GetAll()
    {
        return Ok(
            this.people
        );
    }

    [HttpGet("users/{id}")]

    public ActionResult<Person> Get(int id)
    {
        var pipe = new searchClient();
        var data = this.people;
        var looking = pipe.getClient(id, data);

        return Ok(
            looking
        );
    }

    [HttpPost("add_user")]

    public void AddClient(Object data)
    {
        for (int x = 0; x < this.people.GetLength(0); x++) {
            this.people[x] = data; // Error
        }
    }

}

I'm learning C#, I don't understand what I'm missing

I am new to C# and .NET. I would like to know how I traverse an object that I am creating.

public ActionResult<Person> Get(int id)
    {
        var pipe = new searchClient();
        var data = new[] {
            new Person { id=1, Name="Ana", edad="24" },
            new Person { id=2, Name="Joseph", edad="20" }
        };
        var looking = pipe.obtenerCliente(id, data);

        return Ok(
            looking
        );
    }

public class searchClient
{

    public Object obtenerCliente(int id, Array data)
    {
           foreach(var d in data) {
              Console.WriteLine(d); // Cuando recorro la matriz, me sale el contexto de los objetos
           }
        return data;
    }
}

public class Person
{
    public string Name { get; set; }
    public string edad { get; set; }

    public int id { get; set; }
}

When I go through the array with the foreach, in the console it returns the context of the Person object, I don't know how to continue going through that

I'm making a web, and I get these errors on the console. Everything worked fine before, I didn't make any changes to the project's native path, the project is in codeigniter 3, I don't know what's going on

Source mapping error: Error: request failed with status 404

If someone can explain to me why this happens, the routes are fine, when I click one of those routes it redirects me to the css/js

This is my vendor directory in assets assets

How about guys? I have a problem, in my ionic project I have created a splashscreen in my app, I want that splashscreen to remain active while the application is completely initialized.

app.component.ts

import { timer } from 'rxjs';

I am important timer to control the time that the splashscreen is active

export class AppComponent implements OnInit {
showSplash = true;

initializeApp() {
this.platform.ready().then(() => {
  this.statusBar.styleDefault();
  this.splashScreen.hide();

  timer(10000).subscribe(() => this.showSplash = false); -> aqui esta el problema
});

} }

What I want is that

The SplashScreen remains active until the application is completely initialized and not for a time defined by you

I have downloaded an Ionic template here: https://github.com/arjunsk/ionic-shopping-cart-2 . But I try to start it with ionic serve but it won't let me. The truth is I don't know how to include the ionic template in my project, I haven't gotten any information on the Internet.

Basically, I want to include the template and run it with

ionic serve

After using npm install and trying to run ionic serve I get this

I am trying to run ionic in this directory

What would be the root directory of the template

I am trying to search for the numbers within a string, when I do so it only returns the last number of that string.

var exp = string.match('\:\d*[0-9]\,');

What I try to do is search for the numbers that go after the character : and before , but it doesn't work for me

var string = 'Caja_cebolla X100 :1.5, Caja_tomate :2, Caja_cebollin :0.25'; // Busco que me tome los números que estan delante de : y antes de ,
var exp = string.match('\:\d*[0-9]\,');
console.log(exp);

Basically I'm looking for the numbers after : and before ,. Example:

In Caja_cebolla X100 that I take the number 1.5

I am making an application and I have to dynamically add/remove values ​​to an object in JavaScript, the point is, that I have to add the most updated values ​​to the object and not just any.

var arreglo = [
        {"id":0,"producto":["Tomate"],"productos_datos":["1-1-1","1","1","1","1"]}, // <- Este registro debe quedar eliminado, porque es antiguo
        {"id":1,"producto":["Tomate"],"productos_datos":["1-1-1","1","1","1","1"]}, // <- Este registro debe quedar eliminado, porque es antiguo
        {"id":2,"producto":["Tomate"],"productos_datos":["1-1-3","1","1","1","3"]}, // <- Este registro debe permanecer, porque es el mas actualizado
        {"id":3,"producto":["Cebollin"],"productos_datos":["1-1-1","1","1","1","1"]}
    ]

I have tried with several codes but it does not update me, I have tried with a forEach and it only gives me the first value and not the most updated

var hash = {};
filteredCategories = arreglo.filter(function(current) 
        {
          let go = current.id !== undefined ? String(current.id) + String(current.producto) + String(current.productos_datos) : String(current.id);
          
          let exists = !hash[go] || false;
           
          hash[go] = true;
          
          return exists;
        });

filteredCategories.forEach(category => {
            if (!filteredCategories.find(cat => cat.id == category.id && cat.productos_datos == category.productos_datos)) {
                const { id, producto, productos_datos } = category;
                filteredCategories.push({ id, producto, productos_datos });
            }
        });

Starting from the arrangement that I leave here, I will put the result that I am looking for:

var arreglo = [
        {"id":2,"producto":["Tomate"],"productos_datos":["1-1-3","1","1","1","3"]},
        {"id":3,"producto":["Cebollin"],"productos_datos":["1-1-1","1","1","1","1"]}
    ]

As you can see, there are only two products and there are no repetitions, the products are up to date and it's fair, that's what I'm looking for, but I can't solve it

I'm trying to replace the > character with # inside the HTML5 code tag . The problem is that the > code character is replaced and it gives me an error in the HTML5 source code.

This is the string in which I am looking for those characters

window.setInterval(function(){
        if ($('>title_theme').val().length &gt= 1) {
            cargarArchivo(
                'POST',
                'http://labex.com/PostsController',
                'title_p=' + $('>title_theme').val()
            );
        }

The above code is wrapped in the code tag to be displayed as snippet code on my web page.

$('>title_theme') El caracter > debe ser reemplazado por #

I have tried to replace the > character but it changes the > character of the code itself , resulting in an error in the HTML5 source code (the snippet code is simply not displayed)

Use preg_replace to find and replace

$simbolos = array(
                                    '/</uim',
                                    '/>/uim',
                                    '/\<code\>/uim',
                                    '/&amp;\>\b39/uim',
                                    '/&amp;\bquot/uim',
                                    '/&amp;\blt/uim',
                                    '/&amp;\bgt/uim',
                                    '/\<\/code\>/uim',
                                );
                                $reemplazos = array(
                                    '<',
                                    '>',
                                    "<div class='code'><pre class='prettyprint'><code>",
                                    "'",
                                    '"',
                                    '&lt',
                                    '&gt',
                                    "</code></pre></div>",
                                );
                                $resultado = preg_replace($simbolos, $reemplazos, $request->getSend()->input('content'));
                                echo $resultado;

Without the preg_replace replacements the content would look like this:

window.setInterval(function(){
        if ($(&>39>title_theme&>39).val().length &gt= 1) {
            cargarArchivo(
                &>39POST&>39,
                &>39http://labex.com/PostsController&>39,
                &>39title_p=&>39 + $(&>39>title_theme&>39).val()
            );
        }

Trying with the code:

$resultado=str_replace('>','#',html_entity_decode($request->getSend()->input('content')));
echo $resultado;

The result would be the following:

 <code#
window.setInterval(function(){
        if ($(&#39#title_theme&#39).val().length &gt= 1) {
            cargarArchivo(
                &#39POST&#39,
                &#39http://labex.com/PostsController&#39,
                &#39title_p=&#39 + $(&#39#title_theme&#39).val()
            );
        }
  </code#

It would be nice to replace all the # that are between code and /code , not to replace the < and > of the code tags

I have tried using .htaccess to hide two folders from the browser's URL bar, and only have to put the name of the view file

For that use

RewriteRule ^(.*)$ resources/view/ [NC]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [NC]
RewriteCond %{REQUEST_FILENAME}.view.php -f
RewriteRule ^(.*)$ $1.view.php [NC]

The problem is that I don't get it, I treat the view file as if it were a directory of folders:

This is the structure of my project:

Now, what I am looking for is that the URL ignores the resources/view/ folders and that when I put the name of the file in the URL it shows me the view. As in the image that I posted first above, the URL shows that I put "php.devel.com/test/php_tests/blog/profile" that URL should show me the view profile.view.php.

I have also configured .htaccess so that it ignores the extensions of the .view.php or .php files, that is why I only put the profile without the extensions in the URL

Well, I'm experimenting a bit with the files using C language. But when I ask the user to enter the name of the file to modify and its content, the console closes and doesn't respond... I thought it could be a memory problem, but I'm not sure

int n, de_1;
char * dir, * con, * r_dir;

printf("(nuevo file = 1, agregar texto en file = 2, sobrescribir file = 3, limpiar file = 4, renombrar file = 5, eliminar file = 6)\n");
scanf("%i", &n);

switch(n)
{
    case 1:

        printf("\nEscribe tu nombre de fichero para ser creado:\n"); scanf("%s", dir); c_file(dir);
        exit(-1);

    break;

    case 2:

        printf("\nNombre del fichero para ser sobreescribido: "); scanf("%s", dir);
        printf("\nContenido del fichero: "); scanf("%s", con); swfile(dir, con);
        exit(-1);

    break;

    case 3:
        printf("\nNombre del fichero para agregar contenido: "); scanf("%s", dir);
        printf("\nContenido del fichero: "); scanf("%s", con); wrfile(dir, con);
        exit(-1);

    break;

    case 4:
        printf("\nNombre del fichero: ");
        scanf("%s", dir);
        printf("\nLimpiando archivo...");
        sleep(2000);
        d_file(dir);
        printf("\nEliminamos su contenido"); exit(-1);
    break;

    case 5:

        printf("\nNombre del fichero a cambiar y nombre nuevo: ");
        scanf("%s %s", dir, r_dir);
        rename(dir, r_dir);
        exit(-1);
    break;

    case 6:
        printf("\nNombre del fichero: ");
        scanf("%s", dir);
        remove(dir);
        exit(-1);
    break;

    default:
        printf("Error");
        exit(-1);
        break;
}
return 0;

I am new to C and I am learning it, the code that I passed is from the main function. I also clarify that functions like c_file or swfile are proprietary functions that you create in another file and attach as a header

bool vr_file(FILE * fp) // Saber si un fichero existe o no
{
if (fp != NULL) {

    return true;
} else {

    return false;
}
return 0;
}

char c_file(char * dir) //Comprueba si existe el fichero y si NO existe procede a crearlo
  {FILE * fp;
fp = fopen(dir, "r");

if (vr_file(fp) == false) {

    fp = fopen(dir, "w+");
} else {

    return 1;
}
fclose(fp);
return 0;
}

char rd_file(char * dir) //Lee un fichero y devuelve un conjunto de caracteres
{char * texto;
FILE * fp;
fp = fopen(dir, "r");
if (vr_file(fp) == true) {

    while((texto = fgetc(fp)) != EOF)
    {
        printf("%c", texto);
    }
} else {

    printf("No hay nada escrito");
}
fclose(fp);
return 0;
}

char wrfile(char * dir, char * text) //Crea un fichero si no existe y SI sobreescribe contenido
{ FILE * fp;
fp = fopen(dir, "w");

if (vr_file(fp) == true) {

    fputs(text, fp);
} else {

    c_file(fp);
    fputs(text, fp);
}
fclose(fp);
return 0;
}

char swfile(char * dir, char * text) // Crea un fichero si no existe, y si existe NO sobreescribe contenido
{FILE * fp;
fp = fopen(dir, "a");

if (vr_file(fp)) {

    fseek(fp, 4, SEEK_END);
    fputs(text, fp);
}
fclose(fp);
return 0;
  }

int size_f(char * dir) //Devuelve un entero en bytes del peso del fichero
{FILE * fp;
fp = fopen(dir, "r");

if (vr_file(fp)) {

    fseek(fp, 0, SEEK_END);
    return ftell(fp);
}
return 0;
}

char d_file(char * dir) //Limpia el contenido del fichero

Hi, that is the error that I get. I need that space to generate a random number but it gives me an error

Hi, I just want to know that, I've noticed that there are people who put, for example: @fopen() or @fwrite(), etc... I can't find why they do that so I've come to ask.

The problem I have is that it does not add the values ​​of several arrays contained in an array, I do not know why, here is the code:

<?php
    function solution($number) {
    for ($i = 0; $i < $number; $i++) {
                $multiplo = $i * $number;
                $arreglo = [];
                $arreglo[$i] = str_split($multiplo);
                print_r(array_sum(array_column($arreglo, '0')));
            }
        }
    solution('3');
?>

I am making a regular expression that validates the Venezuelan identity card and I succeed

if(preg_match_all("/(\d*[0-9]{2})/", $cedula, $resultado)){

    print_r($resultado);
} else {

    echo "No hubo resultado";
}

the problem is that I want the user to enter the values ​​like this:

$cedula = 18.842.389;

that is, I want my regular expression to take into account the . let the user enter
