Use of exe-exported functions

As far as I know. exe and dll It's basically the same thing. dll Yes. Export table♪ Previously, I tried to export from exe Something simple. Sleep()) Now it's necessary, but it's complicated. What's going on:
I'm submerging an exesexist from another exeschenic with help. LoadLibrary()(sighs)GetLastError()returns 0, receives ph GetProcAdress()(sighs)GetLastError() It's also zero. In the executory that exports, about this kind of code
```
extern"C" _declspec(dllexport) void go();
static int a=0;
void go()

{

a=1;

}
```
The question is:
If exe I've already started with an exported F.A., and I'm downloading it from the second. exe and calling go()whether the current process will change the variable а?

No.
If you download the module, you'll actually have a separate copy of the module that has nothing to do with the same module as part of another process. Each process will have its set of static variables.
(There's no difference between exe and dll, so the dll would be the same)

(I'll try to get a finger in the sky, because apparently, you'll be able to make it through. C++/CLI♪ but I can be wrong ♪Ooh. TextBox Yes. property Text:virtual property String^ Text { String^ get () override; void set (String^ value) override; } I mean, by turning to textBox->Text♪ you get a variable type ♪ String^♪Adjustment from String^ into the mass char - Not the most trivial operation, because String^ - abstraction is much wider than char[]♪ This transformation is correctly done:IntPtr initialStringPtr = Marshal::StringToHGlobalAnsi(initialString); char* converted = static_cast<char*>(initialStringPtr.ToPointer()); // Работаете с 'converted'. Marshal::FreeHGlobal(initialStringPtr); // После этой строчки указатель 'converted' указывает на освобожденный участок памяти! recommend 300 times. (and then think 300 times)before moving away from a comfortable youthful line to a line char*♪

According to documentation in Mozilla, enviar despite being the contracted form of enviar: function(), the contracted form is a named function, while the second is an anonymous function.Note : The shorthand syntax uses named function instead of anonymous functions …foo: function() {}…). Named functions can be called from the function body (this is impossible for anonymous function as there is no identifier to refer to). For more details, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/function#Examples .Source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Method_definitions#Description However if you run the code below, you will see that the contracted form behaves as an anonymous function, at least this behavior I am having when running on Opera.var teste = { nomeada: function nomeada(imprimir) { return !imprimir ? nomeada(true) : console.log("nomeada"); }, curta(imprimir) { return !imprimir ? curta(true) : console.log("curta"); }, anomina: function(imprimir) { return !imprimir ? anomina(true) : console.log("anomina"); } } try { teste.nomeada(); } catch (e) { console.error(e.message); } try { teste.curta(); } catch (e) { console.error(e.message); } try { teste.anomina(); } catch (e) { console.error(e.message); }Another curious point is that in the documentation on Mozilla it speaks that the contracted form cannot be used as.Method definitions are not constructableAll method definitions are not constructors and will throw a TypeError if you try to instantiate them.Source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Method_definitions#Method_definitions_are_not_constructable But when running the code below, I got a different behavior from the pointer. At least that's what happened when you run it on Opera.var teste = { nomeada: function nomeada() { this.nome = "nomeada"; }, curta() { this.nome = "curta"; }, anomina: function() { this.nome = "anomina"; } } try { console.log(new teste.nomeada); } catch (e) { console.error(e.message); } try { console.log(new teste.curta); } catch (e) { console.error(e.message); } try { console.log(new teste.anomina); } catch (e) { console.error(e.message); }Another point is that browser compatibility, short functions can be used only in more recent/updated browsers. However, as you are using VueJS, you are using VueJS. vue-cli, gulp-babel or whatever solution that transpiles your javaScript ES5 for something compatible with old browser, so this is not enough to be a problem.

What is PHPDoc?To not confuse here I will use the term DockBlock some will call doclet or PHPDoc, it doesn't matter, what is important is to differentiate the PHPDoc comment from the PHPDoc tool. The PHPDoc tool automatically generates documentation based on code and DockBlock comments. But you can use other tools to generate this documentation, I particularly prefer ApiGen.DockBlock starts with /**, they originate in javadoc and may (or not) have a multitude of tags starting with @;What is your use?Docblocks are a means of communication between those who make the code and who consume it. When you pass your code to third parties, or get a code this documentation will help you understand, use and modify it. They serve as the basis for generating objective documentation that can address a number of common issues to those who consume the code. Can I freely use the code in my projects? (@license); Who is the author of the code? (@author); What does this function return? (@return); etc.These tags communicate well with the machine they help the IDE understand the code, on the PHPDoc website there is a list of tags supported by documentation generation tools.There are also frameworks such as Doctrine and PHPUnit that accept their own tags in these comments. With them it is possible, for example, to map and generate the entire database or entities of an application with the Doctrine but this use is already out of the question of documentation.How to use?Within the philosophy of Robert C. Martin the basic rule I recommend is: put as little comments as possible but enough to be clear.The exception is if you will publicly provide the code then - for example the most common open source systems in PHP - the more explained the better, outside this case is rarely worth the energy documenting a lot. Remember that you will have to keep the comments consistent with the code, it is very common for the code to be refactored and the comments to pass wrong information because they are faded, so many consider comments as a type of code duplication.Any code, function, variable, class, should be clear enough to understand what they do and are within their context, without needing any comments explaining. When we do not achieve this ideal a comment is welcome. It can be an alert, clarification or explanation. But these comments are always failures of our ability to express themselves through the code. When necessary it should be precise and clear not to confuse, a bad comment more intricate than helps.There are many tags in the phpdoc standard, but I don't think it's ideal to keep most of this information in a DocBlock, when they're in it they're usually just firulas. Authorship, version, modification, for example get better in a version control system. Other examples of bad comments are those obvious or redundant in relation to the code, are just pollution.Example of useless documentation:/** * Entidade Usuário */ class user { /** * nome do usuário */ $nome; //... /** *Estabelece o Nome do usuário */ function setName(){//... } /** *Pega o Nome do usuário */ function getName(){//... } // … } What is worth documenting is usually the types returned by the functions, types of variables, and types of parameters. Even so it only documents when induction is not possible (With PHP 7 the need for documentation should decrease). It makes life easier. Do you have a rule, PSR recommendation about it? If so, which one?The code presentation rules on PSR-2 apply to DocBlocks, otherwise there is only one developing draft that may be a recommendation in the future. It can be read here: https://github.com/phpDocumentor/fig-standards/blob/master/proposed/phpdoc.md

I'd like to share my answer in three parts:If you just take your code and put it in the front lines. чебурек and монгол - He'll get out. чмеобнугроелк♪ I see that all the letters are present and some are, for example, о - more than once.You don't have any sortings in the code, so it's unsorted.In the case of formal injection, it is generally assumed that each element enters only once. Obviously, this function and the code just cannot work.Look, you've got i and j indices that are meant to run for two lines transferred.But you change them at the same time. You are.You don't know that you've reached the end of the shortest word. The increase in each index continues until the end of the long termYou don't want to see if there's an added element (or elements) in a multiplicity.A logical implementation would be:We're creating an empty-resulting lot.We're running the first line. For each letter of the first line, we add it to the resulting lots.For the second word, it's the same.Some of the code could look like this, (windows.h is used for the normal withdrawal of the Russian letters in code 1251, it can be dropped, but then it can't work with the salt, but only with the files, apparently)#include <iostream> #include <string> #include <algorithm> #include <windows.h> #include <fstream> using namespace std; // сюда переадется слово и стока, представляющая объединенноее множество символов. // так как пеердача просиходи по ссылке - я прямо здесь меняю это множество. // поэтому функция имеет тип void - возвращать из неё ничего не надо void add_word_and_sort(const string& src, string& dst ){ for( auto& ch : src ) if ( dst.find(ch)==string::npos ) dst += ch; sort( dst.begin(), dst.end() ); } string str_conjunction(const string& a, const string& b) { string c = {}; add_word_and_sort(a, c); add_word_and_sort(b, c); return c; } int main(){ SetConsoleCP(1251); SetConsoleOutputCP(1251); ifstream inp("input.txt"); string s1 , s2; inp >> s1 >> s2; string rez = str_conjunction( s1, s2 ); cout << rez << endl; } Actually, there's a standard container set. He's beautiful, and he's just shaking a lot of things.

Um, it smells. undefined behaviourWhether or not it's true. In fact, if the Windows Remembrance Manager already acquaints with his low-level log of downloaded modules, reloading it into the same virtual space should not be done (although depending on Windows and LoadLibrary implementation) - it should simply return the address of the already imported library.The approach you use is likely to be incorrect, but in order not to get into your debrie, it may be recommended that:Check the library in your memory before you blindly call LoadLibrary anywhere.Use it. https://msdn.microsoft.com/ru-ru/library/windows/desktop/ms684179(v=vs.85).aspx for safer loading DL`ocTo make sure you compare the addresses of any of the same imported functions before and after the attempted re-import of the second liba (aka after calling it DllMain, aka after LoadLibrary inside 1 liba) so as to make sure that there is no update on the table of addresses of functions, and the re-loading of the library does not affect the memory.

The message you indicate:Function "summed" is never usedis only a warning, currently IDE Android Studio indicates that values are unused and are recommended to be deleted.in this case you can see that the view parameter is not used within the function, the only reason to add as parameter the view is if you call the function from the layout by android:onClick="sumado": fun sumado(@Suppress("UNUSED_PARAMETER")view: View) { val a:Int=Num1.text.toString().toInt() val b:Int=Num2.text.toString().toInt() val mos:Int=Suma(a,b) Mos.setText(mos.toString()) } Otherwise if you are not calling the function by android:onClick, although mandes call the function with the view parameter this will not be used therefore is not useful, your function should only be: fun sumado() { val a:Int=Num1.text.toString().toInt() val b:Int=Num2.text.toString().toInt() val mos:Int=Suma(a,b) Mos.setText(mos.toString()) }

You can implement it as follows:async function batch_ajax(){ try{ const result = $.ajax({ url: `https://jsonplaceholder.typicode.com/todos/1`, type: 'GET' }); return result; }catch(error){ return null; } } $(document).ready(async function() { let batch = await batch_ajax(); if (batch == null){ document.write("La peticion fallo"); }else{ document.write(JSON.stringify(batch)); } });<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>In the ready is to do the Ajax consultation, this as has a await role batch_ajax wait until you get an answer, once you get the answer, run the other processes, it is also advisable to put them inside a try/catch so you can control whether the server fails or not.

If I understand what you want, you need to declare the parameter as a pointer for a function. So:#include <stdio.h> void comeco_fim(void (*func1)(void), void (*func2)(void)) { printf("começo"); func1(); //está usando a variável para chamar a função printf("texto"); func2(); printf("fim"); } void funcao1() { printf("funcao1"); } void funcao2() { printf("funcao2"); } int main(void) { comeco_fim(funcao1, funcao2); //está passando as funções definidas acima. } See http://ideone.com/6ZE5N2 . And https://repl.it/join/sjszvsot-maniero . Also https://github.com/maniero/SOpt/blob/master/C/Function/PointerVoid.c .void (*func1)(void) indicates that the variable func1 will be the function type that receives no parameter and returns nothing. Only a function with this signature can be passed as argument for this parameter.

It depends on which package you are using Knn, but usually to evaluate the model you use the function predict(modelo, novo_dado).Follow an example using the package caret that already chooses the best parameters automatically:library(caret) fixar semente RNG para resultado reprodutível set.seed(123) treinar modelo knn utilizando a coluna Species como saída knn_model <- train( Species ~ ., data = iris, method = 'knn' ) print("Resultado do treinamento:") print(knn_model) print("Predição da primeira linha:") print(predict(knn_model, iris[1,])) Output:[1] "Resultado do treinamento:" k-Nearest Neighbors 150 samples 4 predictor 3 classes: 'setosa', 'versicolor', 'virginica' No pre-processing Resampling: Bootstrapped (25 reps) Summary of sample sizes: 150, 150, 150, 150, 150, 150, ...

Why isn't it used?For the of the code that implies.For example, in a loop (do, while, for), we can be sure that the only way out is in the loop itself; well why the necessary condition was fulfilled, well why we use a break.We can then check the code backknowing that to reach an exact point, mandatory has gone through the above points (taking into account the if( ) ... else ...Of course.This not fulfilled in a goto. If we find a label, destination for a goto, There's no way to know. the sequence of instructions that led us there. Where do we come from? Especially if we make our code a sample of goto.What happens in the program when used?Exactly what you expect: jump to the right label. There are no major side effects, nothing bad implicit to use it, except as indicated in the previous paragraph. If you're in a block { ... }, local variables to the block cease to exist and, if these in C++, destroyers are called correctly; everything works as expected.

To write good appendices, we need to study the programming of the years at least 5. Of course, in a month of reading of different books and manuals, you might be saving something very simple to write, but to get involved in the process and understand the different subtleness takes a long time.About design: I understand you're going to be a single developer, and besides the code, you have to learn and design, because especially the mobile platform applications should have it. Of course, everything looks simple in the first place until you start designing it yourself, there's a lot of your thinness and complexity. In this regard, for desktop PCs, it is easier to design, but it is also sometimes possible to waste time for their design and construction under a specific decision.With regard to earnings, all relatively, there's nothing you can do about iOS, and the Android succeeds, everything depends on the application, the ways of coinciding, and so on.It's about grabbing. Conventional C++ and Jav's, kill the dust and use one single-language platform, because on one hand, you'll learn how to write a lot more.That's why I'd like to think and weigh everything, not the easy way. If he can reap special feelings, then I have no doubt you will succeed.
