Having these records in a table:

ID Marca Version TipoVersion CodEstadoMarca

1   XX   0      PPP        C
2   XX   1      CKL        C
3   XX   2      CV         C
4   XX   3      DDD        C 
5   XX   4      ANU        D
6   JJ   0      PPP        C
7   JJ   1      CV         C
8   JJ   2      CV         C
9   JJ   3      DDD        C
10  NN   0      PPP        C
11  NN   1      KKK        C
12  AA   0      PPP        C
13  AA   1      CV         C

I need it to show me the records of the Trademarks where it is true that there is no codEstadoMarca 'D' or a TipoVersion 'ANU' and there is also a 'CV' in tipoVersion

That is, it should show the following:

ID  Marca Version TipoVersion CodEstadoMarca

6     JJ   0      PPP        C
7     JJ   1      CV         C
8     JJ   2      CV         C
9     JJ   3      DDD        C
12    AA   0      PPP        C
13    AA   1      CV         C

I am using SQL SERVER from Microsoft.

One solution I'm trying is:

SELECT DISTINCT T0.Marca FROM TABLA T0 WHERE CodEstadoMarca = 'D'

With this it shows me the Brand code that contains some 'D'

Now the next thing would be to make a select of all the Marks and only show the ones that do not appear in the result of the previous Select. But I don't know how to link it

I have the following validation:

An input where we control with a pattern that there are only 4 figures including the possibility that the figure has 0 on the left.

<input type="text" required title="Debe tener 4 digitos." pattern="\d{4}" minlength="4" maxlength="4" />

But I also need to control through pattern that this figure is within a range between 0100 and 4599 including these 2 numbers.

I have the following declared:

List<Object> misObjetos = new List<Object>();
misObjetos.Add( new { precio = 1500 , nombre = "Ciclomotor" } );
misObjetos.Add( new { precio = 300  , nombre = "Patinete"   } );

How do I access, for example, the price of the second element of the list?

I have tried misObjetos[1].preciobut it doesn't work.

I have the following method in a C# class

void Mimetodo(string parametro1, string parametro2)
{
   // Código del metodo
}

void Mimetodo2(int parametro1)
{
   // Código del metodo
}

and now what I want is to match that method to a variable to make a call later, for example something like this:

va = Mimetodo("5", "4");
vb = Mimetodo2(3);
if (opcion == "1") v = vb;
if (opcion == "2") v = va;
v; // Esto seria una llamada a la función que toca.

That is, I want to save the reference to the call of that function.

Inside a string I have part of an html code with an onclick that calls a function. The problem is that I use double quotes inside double quotes that in turn have double quotes and when I pass it to the stringBuilder object to later build the page, the html code does not build it well for me.

The html code that goes inside the string would be this:

string codigo = "<div class='dropright'>" + 
"<button type='button' onclick='__doPostBack(\"variableUno\",\"1\");'>" + 
 numeroBoton + 
"</button>" +
"</div>"

So with StringBuilder I prepare the string to pass it to a json object format that will be an array of arrays. The code works fine for me if I remove the part of theonclick='__dopostback('variableUno','1')'

StringBuilder sb = new StringBuilder();
sb.Append("[[");
sb.Append("\"" + codigo + "\"");
sb.Append("]]");

Suppose I have a C# program where at one point there is the following:

string dato;
dato = recogerDato();
SiguientePantalla("pantalla2.aspx");

Within the collectData() method there may be a query to a database, or a calculation that may take a long time. Inside the NextScreen() method there is a code where the server takes us to another .aspx form

Is there a way to control with some timer or other instruction the time it takes to execute the fetchData() or NextScreen() method and in case let's say it will take more than 15 seconds, it will interrupt the process with an exception or something similar to show a " Timeout too long" and then run it again if we wanted to?

I have a small program made in Android with a WebView that binds to a URL that is http and not https. When testing the program in the Android Studio emulator it works fine but when I generate a test .apk and install it on the mobile when I try to open the application I get the following message: An error has occurred while parsing the package.

Is it possible that the error is that the WebView binds to an http URL instead of an https ? If so, how can I run the test code with an http link?

I have this element:

<input id="Nombre" class="clase1 clase2 clase3" type="text" />

in JavaScript I can get the element like this:

var item = document.getElementById("Nombre");

Now how can I know if the element "item" contains the class "clase2"

That is, how can I know if an element has a class?

I have 2 fields formed with an input element of type text. These fields will contain a number.

Field 1 must be filled with a number that must always be less than field 2.

By means of a button or when changing the value of one of the 2 fields I get an alert in the event that the condition is not met.

I want to replace the alert with a message with the same validation style that is used in Html5 so that it appears in one of the 2 fields in the event that the condition is not met. The message style must respect the same validation styles that different browsers use.

Here is an example for a case where a field validation is invalid:

var input = document.getElementById('campo1');
input.oninvalid = function(event) {
   event.target.setCustomValidity('El campo1 debe ser mayor al campo2');
}

How to take advantage of oninvalid or another type of event to relate a condition between 2 fields?

I am using Visual Studio 2008. I have a solution with a project of a web page in webforms with some presentation screens. On the other hand I have another solution with a project of another web page with some forms.

How can I add the second solution to the first so that from a page of the first solution it calls the route of the form of the second solution?

I have a list of numbers ordered ascending. Given a value I need to know up to what number of the array and its index corresponds.

List<string> myLista = new List<string>(new[] { "2", "9", "17", "25", "35", "42", "70" });

Being the initial index = 0. For a value = 5, the index would be 1 and the number 9 For a value = 17, the index would be 2 and the number 17 For a value = 0, the index would be 0 and the number 2

This is a possible approximation but I am only interested in knowing the index and value of the last element of the list:

myLista.Where(x => Int32.Parse(x) <= Int32.Parse("31")).ToList() 

I have a Web-service .asmxthat receives some elements (parameters or attributes) from an XML . This XML is sometimes received without some element.

How can my Web-service return an error notice that X element is missing from the request?

How can I do it by validating it with the XSD ?

I need to create an array of dictionaries where the size of this array can vary dynamically.

In this example I create an array of 10 elements and only fill 2. But I need the array to get bigger or smaller depending on the code.

Dictionary<string, object>[] valor = new Dictionary<string, object>[10];

To fill it:

valor[0].Add("llave1","01");
valor[0].Add("llave2","02");
valor[1].Add("llave1","11");
valor[1].Add("llave2","12");

If we were to do the equivalence to a JSON, the structure could be like this:

{  
   "informe":[{ "grupo1" : [{
                            "llave1": "01",
                            "llave2": "02"     
                            },
                            {
                            "llave1": "11",
                            "llave2": "12"
                            }]
                },
                { "grupo2" : [{
                            "llave1": "54",
                            "llave2": "62"     
                            },
                            {
                            "llave1": "35",
                            "llave2": "23"
                            }]
                 }]
 }

IMPORTANT: What I need is to declare the elements dynamically.

I need to pass a value to a function that is executed by an event. This value will be the iteration number that you have in a loop. Or what is the same, I want to pass a number to a function that identifies the HTML element that I have clicked on.

I put the code:

pasos = this.miElemento.getElementsByTagName('li');
var i;
for (i = 0; i < pasos.length; i++) { 
  pasos[i].addEventListener('click', (e) => { miFuncion(i); }); 
}

If I click the element with the 'li' tag, the function will be called miFuncionbut the value of i that I will receive will be equal to pasos.lengthand not the value of the number i that I have as I assign the event to the element.

<div>I have several elements inside a <span>, <button>and <img>aligned horizontally.

I need them to be centered vertically. They must be horizontally aligned and spaced between them occupying 100% of the <div>.

When making the browser window smaller the first 3 elements should be vertically aligned and element 4 should remain horizontally aligned at 3

The code I have centers it vertically for me but I can't get the elements to be evenly spaced horizontally. I also don't know how to make the first 3 elements stand vertically in case the browser window gets smaller.

#container {
  height: 100px;
  width: 100%;
  display: flex;
  justify-content: center;
  align-items; center;"
}

<div id="container">
    <span class="t1">Elemento1</span>
    <span class="t2">Elemento2</span>
    <button class="b1">Elemento3</button>
    <img class="i1">Elemento4</img>
</div>

I have a Datatable with 4 columns in which 5 rows are filled, so in total I have 20 cells filled.

How can I then change the data of the 4 cells that are in row 2 to 4 and from what was in 4 to row 2?

DataTable inicial:

   c1  c2  c3  c4
f1 d11 d12 d13 d14
f2 d21 d22 d23 d24
f3 d31 d32 d33 d34
f4 d41 d42 d43 d44
f5 d51 d52 d53 d54


DataTable final:

   c1  c2  c3  c4
f1 d11 d12 d13 d14
f2 d41 d42 d43 d44
f3 d31 d32 d33 d34
f4 d21 d22 d23 d24
f5 d51 d52 d53 d54

I have a form fill function in JavaScript that allows me to just enter numbers in a text box.

The problem is that it only works on computers and not on mobile devices.

function validarNumero(e) {
    tecla = (document.all) ? e.keyCode : e.which;
    if (tecla==8) return true; 
    patron =/[0-9]/;
    te = String.fromCharCode(tecla); 
    return patron.test(te); 
 }

And in the HTML code part

<input type="text" id="txtNumero" maxlength="10" onkeypress="return validarNumero(event)">

From a parent controller I call another child ( popoverContent )with self.present, the child controller is a typical view in the form of a popup that at the end I close with a dismiss but I want to pass some data to the parent view.

Called within the code of the parent controller:

self.present(popoverContent, animated: true, completion: nil ) 

I close the child view ( popoverContent) with a button action

@IBAction func exitButtonAction(_ sender: Any) {
        self.dismiss(animated: true, completion: nil)
    }

How can I pass a parameter of type String, or Int, or dictionary to the parent view after closing the child view with dismiss ?

I have a project that starts with a LaunchScreenand then starts the Storyboardwith a NavigationControllerfrom which the other views hang.

I would be interested in adding a new view between the LaunchScreenand the Navigation Controller.

How should I do it?

I want my app to not display landscape orientation.

In Xcode I go to 'General', 'Deployment Info' ,'Device Orientation' but I don't find that option.
