C++/CLI Finalization of the Consolidation Annex

There's a function of Main. I can at any time complete the work of the annex by calling return 0;
How am I supposed to do this from another function? I mean, even from a class function. So far, it's only come to cause an exception and to process it in the mein, calling it an exception. return 0;♪ Though I'm not sure it'll work. Like in the block. Catch You can't go back. Anyway, I don't like it.

In the block catch possible Recalate the meaning, so the option you've made will work.
Besides, there's a library function. http://www.cplusplus.com/reference/cstdlib/exit/ from the standard library of C++.
Even if the library function https://msdn.microsoft.com/ru-ru/library/system.environment.exit(v=vs.110).aspx CLR
Finally, there's a function in WinAPI. https://msdn.microsoft.com/ru-ru/library/windows/desktop/ms682658(v=vs.85).aspx
But in general, the exit from the program from where it came from is antipaththern. Perhaps you should reconsider the annex architecture.

It's usually not enough to change the files.You have a problem with the name of the external function. C+++, depending on the type of function returned, adds symbols to the name of the function. Here's the example. nm) for for a programme of translated g+++0000000000400c32 t _ZL10ghtab_findP5ghtabPKvj 0000000000400955 t _ZL10ghtab_initjPFjPKvjEPFiS0_jS0_jE 0000000000400e93 t _ZL14ghtab_remove_eP5ghtabP7ghentry 0000000000400d89 t _ZL14ghtab_remove_kP5ghtabPKvj 0000000000400afb t _ZL14ghtab_traverseP5ghtabPFvS0_P7ghentryE 0000000000400cf2 t _ZL15ghtab_find_nextP5ghtabP7ghentry and this is a suitable piece for gcc0000000000400c1f t ghtab_find 0000000000400ccf t ghtab_find_next 0000000000400951 t ghtab_init 0000000000400e50 t ghtab_remove_e 0000000000400d56 t ghtab_remove_k 0000000000400ae8 t ghtab_traverse And that's the prototype.static struct ghtab *ghtab_init (uint32_t capacity, ghtab_hash fhash, ghtab_cmpf fcmp); static struct ghentry *ghtab_find (struct ghtab *htab, const void *key, uint32_t keylen); static struct ghentry *ghtab_find_next (struct ghtab *htab, struct ghentry *preventry); static struct ghentry *ghtab_remove_k (struct ghtab *htab, const void *key, uint32_t keylen); static struct ghentry *ghtab_remove_e (struct ghtab *htab, struct ghentry *entry); So when ice is looking for her in the library, he doesn't find that name.Prototypes of external functions that have been broadcast by the C-compiler need to be described for crosses like that.extern "C" тип f(...); Or we could use the whole pack.#ifdef __cplusplus extern "C" { #endif .... #ifdef __cplusplus } #endif

Although I am. meters I didn't, but I'll write.(1) There's a feeling that knowing C is even hurting deep research. But C can be studied in 21 days superficially, but there's not much to say.(2) Practice. Practice and practice again. You can read books a long time, but you can't. If you want to know the standard library, you're probably gonna have to read the originals, Stepanova.(3) To understand the course, we need to understand the view. To understand with++, you need to understand with++. Or it's a rephrased first question.(4) C++ is the language name and specification. Visual C++ is implemented from ICU. There are also gcc, clang and some others. It's like asking what a race car is different from a Mercedes pain.5(a) Google. qt is a specific Framworth. VC++ is the development environment. Look at the previous question.

Your assertion that "not right" writing the code where the autogeny wrote it is highly questionable. Yeah, in the classical approach, the basic code is written in .cpp-Fails, however, if you work in the context of a fraimvor, the rules imposed on them should be followed. It is therefore more than correct to write the code where the automatic generator system is initially placed.

The question is how Windows program works... you should read Petzold.On the topic: the communication cycle cannot be located in the designer. In fact, the message cycle is Windows program - everything that makes any unfinished Windows program is the message cycle. It looks like she's tagging this code:int WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { // Initialize app and create main window InitApp(); // Run message loop MSG msg; while(::GetMessage(&msg, NULL, 0, 0)) { ::TranslateMessage(&msg); ::DispatchMessage(&msg); } return msg.wParam; } (the code is slightly simplified because it doesn't check the return on the error of GetMessage. In this particular case, error is unlikely, as all arguments are guaranteed correctly.Normally, the programmer does not write the communication cycle itself, but uses any Framing - MFC, wxWidgets, Qt, etc.I can't say anything about the Managed C++/CLI franc (in my opinion, Managed C+++ refers to C+++ around the same as Javascript refers to Java), but as I recall, for C#, the main programme looks like: static class Program { static void Main() { Application.Run(new MainForm()); } }

Well, it's pretty simple. Let's take a bite.(1) Comparison achieved ERROR_OK == foo()♪ It'll come back. true or falsedepending on the value ERROR_OK and what's gonna get the job back.(2) Results of previous calculation (i.e. true or fals(e) Compared with ERROR_OK♪ That's the same thing. true or false I'm going to take a lead. int (true -> 1, false -> 0)♪ It's a normal comparison.Accordingly, assuming that ERROR_OK = 0 (a) the first part of the condition is equivalent 0 == foo(), i.e. !foo()♪ The second part of the condition is equivalent !foo() != 0, i.e. foo() == 0I mean, just !foo()♪ So if foo Come back. 0the condition will be met, otherwise it will not.

In your example of a global mass, there's a little mistake that's ruining everything.double** wht; double** created(int Nt,int Nx) { double **wht = new double *[Nt]; for (int i = 0; i < Nt; i++) wht[i] = new double[Nx]; return wht; } Inside your functions, you'll revert to the variable double **wht and you'll screen it with the same name. And in addition, you get a memory leak. That's the source of your exceptions, because you have a global index not initialized, and you're trying to use it. Get inside it. created() On:wht = new double *[Nt]; and everything should be paid.

As you've already been advised, it's not C+++, it's C+++/CLI. Nevertheless:using namespace System::Collections::Generic; using namespace System::Text::RegularExpressions; using namespace System::Collections; using namespace System::Text; /// ..... etc { textBox1->Text = "аааааа bbbbb ccc dd eeeee z fffffff y ggggggggg " + "hhhhh iiiiiii " + "jjjjjj"; String^ line = textBox1->Text; label1->Text = ""; String^ reg = R"((\w+))"; array<String^>^ arrLines = Regex::Split(line, reg); for (int i(0); i < arrLines->Length; i++) { if (arrLines[i]->Length > 2) label1->Text += arrLines[i] + " "; } }

Actually, what's out of 84 is luck. System::Runtime::InteropServices::Marshal::PtrToStringAnsi Adopts IntPtr on an unmanageable line, i.e., a complete zero-therminated symbol.You're going there. IntPtr(84)♪ It's not an index to the cell in memory of the meaning. 84, and the sign on the address cell 84♪ What's there is a big question.You'd have done something like that.char some_char[2] = {84, '\0' }; auto ptr = IntPtr(&some_char); System::String^ str = System::Runtime::InteropServices::Marshal::PtrToStringAnsi(ptr); In your case, it's enough to do this:char unmanaged_char = 84; System::Char managed_char(unmanaged_char); OrSystem::Char managed_char(84);

All you've put perfectly in C and C++ so if what you care about is simply migrating it... congratulations, you've already got it!!! To compile it on C++ simply use a C++ compiler and ready.Now, if what you want is for the code to benefit from C++'s goodness and disgusts, you could implement changes like the following:LibreriaIn C++ standard libraries They don't have extensions.. The inherited from C also lose their extension and, to distinguish them a little more, receive the prefix c:C#include <stdio.h> #include <string.h> C++#include <cstdio> #include <cstring> Is this important change? I usually do. This version of the bookstores may include functions within the namespace stdwhich helps to better organize the code and functions.Input/outputC++ has specific objects to manage the output entry. The utilities surrounding these objects usually make the code more readable and expressive.So, printf, puts and others become absorbed by std::coutwhile scanf, gets and company can be replaced by std::cin.C#include <stdio.h> int numero; printf("Dime un numero: "); scanf("%d", &n); printf("Has elegido el numero %d\n", n); C++#include <iostream> int numero; std::cout << "Dime un numero: "; std::cin >> numero; std::cout << "Has elegido el numero " << numero << '\n'; Text chainsWhen we want to handle text in C we have no other choice but to use char* or char[], structures with many limitations and complex to use:In both you have to be careful not to write / read out of the array limitsWith char* you have to handle dynamic memory... danger of memory leakschar[] It doesn't admit redimension... very restrictive.In C++ we have the object std::string which comes to replace these two structures. Being a class has many utilities that allow writing more readable code:C#include <stdio.h> #include <string.h> char nombre[500]; char buffer[500]; puts("Dime tu nombre: "); scanf("%s", nombre); puts("Dime tu apellido: "); scanf("%s", buffer); strcat(nombre, buffer); printf("Bienvendio %s\n", nombre); C++#include <iostream> #include <string> std::string nombre; std::string apellido std::cout << "Dime tu nombre: "; std::cin >> nombre; std::cout << "Dime tu apellido: "; std::cin >> apellido; nombre += apellido; std::cout << "Bienvenido " << nombre << '\n'; Classes and objectsIn C there is no class concept. The most similar are data structures and only serve for structure and group the variables we have to use in our programs.However C++, being object-oriented, gives a new life to the old data structures so that they become more useful:Support builders: Allows to initialize your variables automatically during object constructionThey admit destroyers: Resources can be automatically released.Attributes can be private: Improves encapsulation...Also, as a small big advantage, you don't need to use struct by declaring variables:Cstruct colas{ char clave[100],nc[100],nom[100]; double sueldo; int tiquete; struct colas *sig; }; C++struct colas{ std::string clave; std::string nc; std::string nom; double sueldo; int tiquete; colas *sig; colas() // Constructor por defecto : sig(nullptr) // Inicializamos el puntero sig { } };

A standard approach is used for all languages: xml-comments starting from three symbols ///♪ After the compilation dll, a file of xml containing documentation will be established. If this file is available, comments on the library ' s methods will be available in C# and any other language.Watch the reference. https://msdn.microsoft.com/ru-ru/library/ms177226.aspx ♪For the documentation file to be established in the compilation process, a parameter should be specified https://msdn.microsoft.com/ru-ru/library/ms173501.aspx Compilator. See section "Installation of this compiler parameter in Visual Studio development."I can't point out, even if it says it's manually translated, but the translation is so cunning that it's better to turn into English if you own it. I can also recommend the use of reference materials in other languages, for example https://msdn.microsoft.com/ru-ru/library/b2s063f7.aspx ♪
