I would like to know if I can change the name of the process I am running at run time. Namely:
public static void Main()
{
Process.GetCurrentProcess().ProcessName; // Aquí tendríamos el nombre original que aparece en el ensamblado
//Asignar un nombre nuevo
Process.GetCurrentProcess().ProcessName; // Aquí tener el nombre modificado
}
I would like to know if this is possible and if so, how to do it.
Thank you and regards
I tell you my situation, I have a json file which I get such that:
string jsonData = System.IO.File.ReadAllText(path);
In this case, as an example, a json can be such that:
[
{
"nombre": "Ivan"
},
{
"nombre": "Francisco"
}
]
either
[{
"edad": 55
}]
either
[
{
"dimensiones": 2500
},{
"dimensiones": 800
},{
"dimensiones": 500
},
]
either
[
{
"esNueva": false
}
]
The problem is that I have to deserialize it but I don't know what class it is going to belong to. As in the example suppose I have these 4 classes:
public class Persona
{
string nombre{ get; set; }
}
public class Animal
{
int edad{ get; set; }
}
public class Ropa
{
bool esNueva { get; set; }
}
public class Foto
{
int dimensiones { get; set; }
}
The idea is that the json is one of those classes but I don't know which one exactly. I've thought about making a class that resolves the string that corresponds to the json, but I don't know how to make a method that can return an object that I know but I'm not sure what it is.
How could I do this method?
I have to implement an onClick method for the following button:
<Button layoutX="150.0" mnemonicParsing="false" onMouseClicked="#FilterList" text="Buscar"/>
Well, in the method that I have implemented is the following:
@FXML
private void FilterList() throws IOException{
List<Player> players = guiApp.getController().getPlayersByName(searchId.getText());
displayPlayers(players);
}
GetPlayersByName simulates a database call:
public List<Player> getPlayersByName(String name){
List<Player> response=new ArrayList<Player>();
for(Team t : this.getTeams())
{
response.add((Player) t.getSquad().stream().filter((o->o.getName().contains(name)|| o.getSurname().contains(name))));
}
return response;
}
The problem is that when I run it I get the following exception:

And I have no idea how to fix it, do you have any ideas?
I know that '*' is used to define a pointer at the time of creating a variable, for example:
objeto* variable;
But, in this case from a university exercise:
function_init(tPopularity* object) {
tPopularity newPopu;
/*Relleno de de datos, no importante para la pregunta*/
object=&newPopu;
}
My initial idea was to leave is the one above, that is:
object=&newPopu;
The problem is that when exiting the function the data of the object was lost, so what I have done, without knowing very well why it is:
*object=newPopu;
And works! My data is not lost and the tests pass correctly... now my question is... Why are my results now as expected? Why was the data corrupted and why not now? What does that asterisk in front of an assignment mean in my code?
I was doing some exercises when I saw the following: I have this function:
bool film_equals(tFilm* film1, tFilm* film2);
And when I wanted to use it, I didn't need it with pointers, so it would be something like this:
if( film_equals(&film,&temporal->e.film)==true)
{
isFavorited=true;
}
Being tFilm filma parameter of the function and temporal->e.filma node whose value is the movie
My question here is... why does it fail if I don't put & in front of the parameters? What exactly does this mean for my values?
I was wondering how to show or hide the console when launching a console application (.NET Framework)
I have to implement the pop method of a stack in C and I have done the following:
Stack_pop(tStack *stack) {
if (stack != NULL)
{
tStackNode *node = malloc(sizeof(tStackNode));
node=stack->first->next;
stack = node;
}
else
{
return -1;
}
}
In theory it should work: I first get the node corresponding to the next one and then assign it as the current node. But when I try it, it hangs, so it's a memory allocation error. The tStack struct is as follows:
typedef struct tNode {
tValue e;
struct tNode *next;
} tStackNode;
I have the following question. I have the following structure
typedef struct {
tPilaStackNode *first;
} tPilaStack;
As you can see, it has the following structure
typedef struct tNode {
tPila e;
struct tNode *next;
} tPilaStackNode;
Which in turn contains the following structure:
typedef struct {
tElement element;
} tPila;
(As you can see it does not stop there, however for my example this is enough)
As I can see, if the main element is a stack, therefore what I want is to create a function that adds an element to the stack, that is, a push.
PilaStack_push(tPilaStack *stack, tPila Pila) {
}
My doubt is the following: I have to allocate memory for each struct that is contained, that is:
stack=(struct tPilaStack*)malloc(sizeof(struct tPilaStack))
stack->first=(struct tPilaStack*)malloc(sizeof(struct tPilaStack))
stack->first->next = (struct tNode*)malloc(sizeof(struct tNode));
Or is it enough to do it for a specific level?
I've been seeing it used in some places =>when declaring attributes on a class. For example:
public class Escritor: IProfesion
{
public string Trabajo => "Copywriter";
public string PalabraFavorita { get; set; }
}
How does it =>affect Trabajoya Escritor?
I have a problem that I don't know how to solve.
I have an object Movimientos, and after a call to an ApiRest, I get a list of them, which I deserialize as follows.
result = JsonConvert.DeserializeObject<List<Movimientos>>(contenido);
So far perfect, the problem is when my call to the Api returns only a Movimiento, that the same deserialization line skips:
{"Cannot deserialize the current JSON object (eg {\"name\":\"value\"}) into type 'System.Collections.Generic.List`1[Moves]' because the type requires a JSON array (eg [ 1,2,3]) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON array (eg [1,2,3]) or change the deserialized type so that it is a normal .NET type (eg not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object."}
How can I make it work with both a json containing a list and a single item?
I edit with more simplified data: An example json returned by the api is
string contenido = "{ \"NumeroOrden\":null,\"Operacion\":null}";
And the Movements class
public class Movimientos
{
public string NumeroOrden { get; set; }
public string Operacion { get; set; }
}
Edit: The Json I get must be immutable. What the api returns is not mine, it does not depend on me and therefore it cannot be modified .
I have to make a function that removes trailing whitespace from a string.
The function is as follows
void user_trimCapitalizeName(User *object){}
For what concerns us, it Useris a structsuch that:
typedef struct
{
char *name;
} tUser;
Well, my idea is the following: I create a vector that copies the string of the object that is passed to the function and I also obtain its length.
char *name = malloc(sizeof(char) * strlen(object->name));
name = strcpy(name, object->name);
Now I create some auxiliary functions to measure and obtain data and go through the string from the end until it finds a character, that is, as long as what it finds are blank characters.
int finalBlankSpaces = 0;
int nameLength = strlen(name);
int lastChar = nameLength-1;
while (name[nameLength] == ' ')
{
finalBlankSpaces++;
nameLength--;
}
lastChar = nameLength;
I will use these data later to make a substring and thereby "eliminate" the empty characters.
The problem is that for any name, for example, "Pedro Duque "it doesn't directly enter the loop. The fact is that I have made another function the same but to eliminate the characters before the name and it works. Why not the other way around?
I am new to Cand the main differences with other languages in which I am more advanced is the use of memory.
I am doing the following exercise:
Given the definition of T in the Th file, it is proposed to implement: T_mdfyTitle(): Modifies the data of type T received as a parameter, with a new name. Note: Correct memory management must be performed.
being T:
typedef struct {
char* name;
int code;
} T;
For me in Java or C# it would be as simple as a setter, so I've implemented:
tError T_mdfyTitle(T* object, const char* newName){
object->name=newName;
return OK;
}
Now... when I reread:
Note: Correct memory management must be performed.
I think I'm not doing something right. Does my code correctly manage memory? And going further, when do I know that I have to manage memory?
Suppose we have a string that represents an equation:
string ecuacion = "x^4-x^3-5x^2-x-6";
And we want to get the space between the operators:
char[] operadores = new char[] { '-', '+', '*', '/' };
If we use string.Split();to separate the modules from each other in a list in the following way:
List<string> subEcuaciones = new List<string>();
subEcuaciones = ecuacion.Split(operadores, StringSplitOptions.None).ToList();
The result we get is:
x^4
x^3
5x^2
x
6
However I would like to preserve the operator by which they are delimited, i.e. get as a result:
x^4
-x^3
-5x^2
-x
-6
Is there a setting to preserve the operators?
I have recently started programming in javascript and I have noticed that in some examples it is used ==and in others===
Is there a reason why one of the two in particular is not always used?
I am developing an application MVC .Netthat has a visual part in cshtml. The problem comes in the following part: I have a button to select a file defined like this:
<div class="col-sm-4">
@Html.TextBoxFor(m => m.Data, new { type = "file", @class = "upload " })
@Html.LabelFor(m => m.Data,"Upload File...", new { type = "file", @class = "btn btn-primary" })
</div>
It is this way to be able to style it and make it look like a button, it is shown as follows:
The problem is that when I select a file the text value is not changed Upload File...
. Is there some kind of event that is fired when select a file? What is the optimal way to do this? All the best
Is there a difference between the interfaces IEnumerable, ICollectionor IList?
At what point should each of the interfaces be used in my developments?
I would like to get the path of a file to later upload it to my server. I have a button in the Views such that :
@Html.EditorFor(model => model.Imagen, new { htmlAttributes =
new { @class = "input", @type = "file" }
The problem is that in the controller I only get the name of the file and I need the full path. As I have investigated this is because modern browsers do not allow it for security. In that case, what would be the valid way to get the route?
