How's the C++CLI C# code removed?

Perhaps one of the main questions left is how the C++CLI exemptions are handled.
C++CLI combines a controlled and unmanageable code and adds to a C# code controlled.
As on the C# side, correctly process C++CLI exemptions:
- If there is no code in the controlled part CLI try\catch blocks <exception>?
- If the code is in the controlled part CLI try\catch blocks <exception>? Keep moving?
- If on the side of the uncontrollable code AcсessViolationand in the controlled part CLI this method is in the block try\catch - Is the annex falling?

The exceptions between libraries and languages should be deleted.
There is no fixed ABI in C++, even different versions of the compiler can be performed in different ways.
If you want a reliable and transportable code, you'll have to contain exceptions within one binary.

static ConvertedString(); - it's an announcement. https://docs.microsoft.com/en-us/cpp/dotnet/how-to-define-and-consume-classes-and-structs-cpp-cli?view=vs-2019#BKMK_Static_constructors a special method which is caused by the performing environment in setting up the dominance of the annexes and can be used to initiate the global state of the class. The implementation of the static designer must be somewhere further in the .cpp of the file.ConvertedString(const wchar_t const * data, int ActualLength) ... - implementation of the designer of a copy of the facility. The designer of the copy may be privatized for various reasons: because there is another design causing it or a statistical method shall be used to create a copy.
The code above works after the code below.

Your problem has a very simple solution, and I recommend that you always use this improvement, because as a possible future programmer, this will help your colleagues to be able to review your code in the future.Use always {} for if/else, even if there is only one option or one line of execution. In your case, the solution is:if((numero % 2 == 0) && (numero >= 0)) { printf("El número es par positivo"); } else { printf("El número no es par positivo"); } Since, according to your code, having put ; at the end of the if, the compiler runs your if as a simple sentence (type add, execute a method, save a value) and then, make the print.But, as you also have a else below, it's a compiler. if that contains it, since, unlike the if, yes it is possible to have a thousand ifindividual, but you can't have a else without being content in your if.

If the text field is directly accessible from two or more reading-writing streams to avoid interaction, different types of synchronization are used. The MSDN example you've given uses the variable usingResource, which changes and compares with atomar operations. Ultimately, the code that will address the Interlocked challengesif ( 0 == Interlocked::Exchange( usingResource, 1 ) ) { // ... // Здесь осуществляется доступ к защищенному ресурсу Interlocked::Exchange( usingResource, 0 ); protected against multiple entry, i.e., there is no possibility that, for example, one flow begins to read the variable meaning, and in mid-reading the flow is clicked and written into the variable. The logic is simple, once one flow is within the Interlocked section, the value usingResource is equal to one, and all subsequent flows are no longer part of the Interlocked section until the first flow is out.

In order to work with Excel, reference should be added to the library of the types "Microsoft Excel... Object Library." An example of the connection to imputed Excel and the change in the unit value in the active sheet is:using namespace System; using namespace System::Runtime::InteropServices; using namespace Microsoft::Office::Interop::Excel; int main(array<System::String ^> ^args) { Application^ app = nullptr; Object^ sheet = nullptr; Worksheet^ ws = nullptr; Range ^ cells = nullptr; Range ^ cell = nullptr; try { //подключаемся к активному экземпляру Excel app = (Application^)Marshal::GetActiveObject("Excel.Application"); if (app == nullptr) throw gcnew ApplicationException("Fatal error: Running Excel instance not found!"); //находим активный лист sheet = app->ActiveSheet; if (sheet == nullptr) throw gcnew ApplicationException("Fatal error: No active sheet in Excel!"); ws = (Worksheet^)sheet; //переходим в ячейку и устанавливаем ее значение cells = ws->Cells; cell = (Range^)cells->Item[1, 1]; cell->Activate(); cell->Value2 = gcnew String("Hello from C++/CLI!"); } finally{ //очистка ресурсов if (cell != nullptr)Marshal::ReleaseComObject(cell); if (cells != nullptr)Marshal::ReleaseComObject(cells); if (ws != nullptr)Marshal::ReleaseComObject(ws); if (sheet != nullptr)Marshal::ReleaseComObject(sheet); if (app != nullptr)Marshal::ReleaseComObject(app); } Console::WriteLine("All done! Press any key to exit"); Console::ReadKey(); return 0; }

If abstracted from syntax, C# and C++ have several cardinal differences:C# (also as J#, VB# and other) works over some virtual machines called dot NET Framework. I mean, objective code C# generates codes for virtual (a) Not a physical car. Accordingly, where there is this C# virtual machine I'll work everywhere. It's called redundancy, The private consequence is that that the dimensions of C# are fixed. C++ collects an objective code for specific platform: Windows x86, Windows x64, Linux, Sparc, etc. The sizes of the types and http://en.wikipedia.org/wiki/Endianness different, so when the code is moved platforms There are problems.C# automated problem installations (i.e., collector garbage). Ideally, it's just a pass. creates facilities and is already a collector The trash can handle who and when destroy. B C+++ opposite memory management Proger. It's a whole science thing. How to correctly manage memory, I don't want her to leak.Of course, there's a more delicate difference, but that's the details. I pointed out the main differences.

C+-- always platform-dependent, C# usually AnyCPU. As a result, the C# programme may not be launched with the decoration supported by the library.As a crutch, the consulate application platform can be changed to be common with the library.A more literate solution is the compilation of the library immediately for two platforms, followed by the loading of the necessary library version. But this will require deep downing into the collection system.

The most appropriate way, as noted in the commentaries, is to reform UI radically.Interest can be improved by temporarily removing TabControl from the parent counter, and returned after the addition of all TabPage. You can also try to suspend Layout. I mean:this->Controls->Remove(tabControl1); tabControl1->SuspendLayout(); for each (TabPage^ page in tabsArray) { tabControl1->Controls->Add(page); } tabControl1->ResumeLayout(); this->Controls->Add(tabControl1); Removal of shapes can be removed by inserting into the DoEvents cycle:for each (TabPage^ page in tabsArray) { tabControl1->Controls->Add(page); Application::DoEvents(); } But it's a crutch. You may be beaten with your feet. And that would not give the form to freeze, but in general, would greatly increase the overall time of TabPage.The introduction of this cycle into a separate flow would not help, because the registration of the shape controllers still occurs in its flow.As noted in another response, the content needs to be downloaded when selecting the element. In the cycle, get up in TabControl. empty TabPage. Two hundred empty controllers will get up pretty fast, the shape will not be long. And fill every TabPage only when the user switches to it. For that, sign for the SelectedIndexChanged event at the tab Control.Void tabControl1_SelectedIndexChanged(Object^ sender, EventArgs^ e) { // Здесь создаём/берём из ресурсов/откуда-то ещё нужные контролы Button^ button = gcnew Button(); button->Text = tabControl1->SelectedIndex.ToString(); // Добавляем их на выбранную пользователем страницу TabPage^ tabPage = tabControl1->SelectedTab; tabPage->Controls->Add(button); } Naturally, the first TabPage must be filled with contents at once.

I found the answer. http://stackoverflow.com/questions/27442282/using-reflection-invoke #include "stdafx.h" using namespace System; using namespace System::Reflection; ref class Example { public: long Invoked_Function(Int32 a, Int32* pb) { Console::WriteLine("Invoked with {0}, {1}", a, *pb); return 999; } }; int main(array<System::String ^> ^args) { auto obj = gcnew Example; auto mi = obj->GetType()->GetMethod("Invoked_Function"); int b = 666; int* ptr = &b; array<Object^>^ arg = gcnew array <Object^> {42, IntPtr(ptr)}; long result = (long)mi->Invoke(obj, arg); Console::WriteLine("Result = {0}", result); return 0; } It's partly answering the question because you had to do it.cli::array<System::Object^>^pars = gcnew cli::array<System::Object^,1>^{}; cli::array<System::Object^>::Resize(pars,10); UPD: Thank you, Alexander Petrov, the second way to create the mass of the required length is:cli::array<System::Object^>^pars =gcnew cli::array<Object^>(10); And now I found a reference to msdn http://docs.microsoft.com/en-us/cpp/windows/arrays-cpp-component-extensions?view=vs-2017

Uhh.That's right. First, about static♪ Modifier static means “local in this unit of compilation”. I mean, one thing. .cpp-File and his header. That's why. two I see. different Copies static- Transmitting. This, in principle, cannot be used for global variables. I don't understand why you said it was working.The global variables in C and C++, as well as the global positive variables in C++/CLI, are declared as follows:In the ...h-file declaration that the variable is somewhere:extern int x; In the .cpp file, the real announcement is:int x = 5; Global managed C++/CLI variables do not exist but are easily emulated by static layers of static class as specified in https://ru.stackoverflow.com/a/419439/10105 ♪How to get rid of global variables is a long story. I think you should rewrite the classes so they can get the necessary data in the design. Or had references to other classes where the necessary information could be requested. Or another thousand possible ways, you as the architect of the program decide how to share responsibility between your classes. There is no universal recommendation.

Hello Rafael, welcome.One solution to your problem would be you to copy everything in a new .txt file minus the line/band you want to take, then delete the old .txt and rename the new .txt to the old name. It is said to pass that this solution does not only apply in C/C++/C# - when it comes to text/fichary files in .txt, in any language, the only way to create changes is to write a new file.Another solution would be to put the data on an SQL basis where each record can be updated/removed independently.Follow an example of code to delete something from a txt: https://pt.stackoverflow.com/q/200234/ https://pt.stackoverflow.com/q/60095/
