Hello,

Consider the following code:

Copy Code

<br /> class A<br /> {<br /> public:<br /> A() {}<br /> ~A() <br /> { <br /> staticint i = 0;<br /> std::cout << "Destructor called " << ++i << " time(s)" <br /> << std::endl;<br /> }<br /> };<br /> <br /> void main()<br /> {<br /> try<br /> {<br /> throw A;<br /> }<br /> catch(A ex)<br /> {<br /> } <br /> }<br />
When I run the code, the output is the following:
Destructor called 1 time(s)
Destructor called 2 time(s)
Destructor called 3 time(s)
Press any key to continue


I can figure why the destructor is called 2 times, but why is it called the 3d time??? Confused   :)
Dear Friends,

I got a CString. What i want to find out is whether the first character in that CString is a Number (i.e 0 to 9). How can i do so ??
Use .

Yes, use IsDigit(), and you can reference the first character of a CString like a char array (ie )

No, in fact what happens is that when I reached a breakpoint, I can see the taskbar but the rest of the screen is still black (wathever I do, also using alt+tab).

You can override OnOK() (and possibly OnCancel()) and in your overridden method,
do nothing.

Creating a C++/CLI Wrapper

C++/CLI is a programming language created by Microsoft as typeerror error #1009 substitute for the older Managed Extensions for C++, which is now deprecated. As the name suggests, this language offers support for the .NET managed components in a C++ context.

Many people are confused about why this language would be used, instead of the much more widespread and powerful C#. The main reason for this is that C++/CLI allows you to use both managed and unmanaged code, offering you the opportunity to control the memory that is used by your program, error c2512 c+ + mfc, instead of leaving all the decisions to the Garbage Controller. It should be noted that C++/CLI is not usually used by itself to develop software, but rather as a middleware between .NET and C++.

While there are many ways to write C++/CLI programs, in this article I will focus on a particular architecture that I generally used when developing this kind of applications. The solution will contain 3 components: the core C++ project, the C++/CLI wrapper and a C# project that will use the functionality of r-studio i/o device error 1117 core through the wrapper.

A well-known usage of this type of technology is represented by the game engines that allow you to write scripts in C# &#; such as Unity3D or Xenko. Since game engines handle large quantities of data in a small amount of time, writing them in C# to begin with would not be a good idea regarding the performance of the engine. Thus, they are written vba is error C++ and are made available to C# through a C++/CLI wrapper.

Preparations

 

In order to start working with the C++/CLI technology, it is necessary to install the module into Visual Studio, error c2512 c+ + mfc. The first step is to open the Visual Studio Installer and press the “Modify” button. After that, expand the “Desktop development with C++” section on the right side of the window and select “C++/CLI support&rdquo. Then press “Modify” button again.

Creating the Core project

After the installation is done, open Visual Studio and create a new project. For its type, go to Visual C++ on the right menu and choose “Empty project&rdquo. I usually name this project “Core”, as it contains all the main functionality of the software; for the solution, you can choose any appropriate name.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\sprers.eu

Before we start writing the actual code, we have to change the configuration of the project. Right-click on the project in the Solution Explorer and select “Properties&rdquo. Under “General”, select  &#;Static Library (.lib)&#; as the configuration type. This will convert the project from an executable to a library that we can include in other projects. Select “Apply” and “OK&rdquo. This is all we have to do for now so we can start writing code.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\core_sprers.eu

As I mentioned in the introduction, this type of project architecture is common with game engines; therefore, I will create an “Entity” class for this example that would represent a game object in such an engine.

Right click on the project and select “Add->New item->Header file” and name the file
Entity.h&rdquo. Repeat for a C++ file named “sprers.eu&rdquo.

I chose to use a public field error c2512 c+ + mfc the name as well as to get methods for the X and Y position so I can demonstrate how to use both of them in the wrapper. I have also added a void method that changes the position of the entity so that you can see how calling the method from the wrapper will have an effect upon the object from the core project.

//Entity.h

  #pragma once

  namespaceCore

  {

   classEntity

   {

   public:

   constchar*m_Name;

   private:

   floatm_XPos,m_YPos;

   public:

   Entity(constchar*name,floatxPos,floatyPos);

  

   voidMove(floatdeltaX,floatdeltaY);

   inlinefloatGetXPosition()const{returnm_XPos;};

   inlinefloatGetYPosition()const{returnm_YPos;};

   };

  }

As you can see, I have named the namespace “Core”; this may or may not be appropriate for your project. In this example (and in many other projects that I worked on), error c2512 c+ + mfc, the purpose of the core project is only to contain the functionality that is going to be accessed by the wrapper. However, if you intend to use the C++ error c2512 c+ + mfc that will be generated in other C++ projects, the name “Core” might become confusing. In that case, I suggest changing the name to something like “Unity3D-Core&rdquo. You will understand why these names become a problem when we will start developing the wrapper.

As you can see, I also added some printing to the methods so you can clearly see the order of the operations when we execute the program. I have also tried to only include simple operations so that we can focus on the main point of the tutorial, which is accessing this code in a .NET context.

   Entity::Entity(constchar*name,floatxPos,floatyPos)

   :m_Name(name),m_XPos(xPos),m_YPos(yPos)

   {

   std::cout<<"Created the Entity object!"<<std::endl;

   }

   voidEntity::Move(floatdeltaX,floatdeltaY)

   {

   m_XPos+=deltaX;

   m_YPos+=deltaY;

   std::cout<<"Moved "<<m_Name<<" to ("<<m_XPos<<", "<<m_YPos<<")."<<std::endl;

   }

  }

The last thing that I would like to do in this Core project is to create another header file, called “Core.h”, which we will include in the files from the wrapper. This might seem unnecessary for a project of such small scale, error c2512 c+ + mfc, but I highly suggest doing so for larger projects. The reason is that when trying to work with the Core library in other projects, it is easier to include the “Core.h” header file and just take what you need from there, than to go through the process of learning the architecture of p7q57-m cpu fan error project and thinking about which files you might need.

//Core.h

  #pragma once

  #include "Entity.h"

Creating the Wrapper project

Now that we are finished with the core code, we can move on to the wrapper project, error c2512 c+ + mfc. Right-click the solution in the Solution Explorer, error c2512 c+ + mfc, and select “Add->New project”, error c2512 c+ + mfc. Go to “Visual C++->CLR” in the left menu, and select “Class Library&rdquo. I have called the project Wrapper in this case; other names you might use could have the form MyEngine-CLI.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\create_sprers.eu

Before we start writing the wrapper code, we need to add a reference to the Core project, error c2512 c+ + mfc, so that we can use the Entity class that we created there. Right-click the Wrapper project in the Solution Explorer, choose “Add-> Reference” and select the Core project.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\add_sprers.eu

After that, right click again on your project, go to Properties>C/C++>Precompiled Headers and change the first option to &#;Not Using Precompiled headers&#;.

Now that everything is set, we will begin with a class that you can use in all the C++/CLI projects that you will create in the future. I usually call this class ManagedObject. Let’s add a new header file called ManagedObject.h to the wrapper project.

   {

   delete m_Instance;

   }

   }

   !ManagedObject()

   {

   if(m_Instance!=nullptr)

   {

   delete m_Instance;

   }

   }

   T*GetInstance()

   {

   returnm_Instance;

   }

   };

  }

Note: In this example, I created a namespace called CLI for the Wrapper project; this avoids any confusion between the wrapper and the core. However, if you intend to have a more recognizable name for your wrapper namespace (such as the name of your project), it is important to follow the advice that I left in the previous note.

ManagedObject will act as a superclass for all the wrapper classes that we will create in this project. Its sole purpose is to hold a pointer to an unmanaged object from the Core project, error c2512 c+ + mfc. You can also notice that the class contains a destructor (~ManagedObject) – which will be called whenever you delete an object with the delete keyword – and a finalizer (!ManagedObject) which is called by the Garbage Collector whenever tragic error danceforum.ru destroys the wrapper object.

You can also notice that I have defined the ManagedObject class as a template. You will see why when we create error c2512 c+ + mfc first wrapper class. Add a “Entity.h” file to the project, as well as a “sprers.eu&rdquo.

  }

As you can see, we include the “Core.h” file that we created in the Core project, so that we can access all the classes from there. Then we define the Entity wrapper class, which is a subclass of the ManagedObject; you can now see why ManagedObject was a template: so that we can specify the unmanaged class for each of our wrapper classes.

When creating a wrapper class, the idea that you need to follow is that you should declare all the members from the core class that you want to access from the .NET context. In this case, I created a constructor just as the one from the core Entity class – except that it takes error c2512 c+ + mfc String for the name instead of a const char*, the Move methods and, instead of creating get-methods as I did in the core project, I made 2 properties just counter-strike 1.6 dog alfa-antiterror 2010/rus you can see that you will be able to access them from C#.

Before moving further to the “sprers.eu” file, I would like to add a function in “ManagedObject.h” that you will also use a lot in this type of project.

usingnamespaceSystem::Runtime::InteropServices;

  staticconstchar*string_to_char_array(String^string)

   {

   constchar*str=(constchar*)(Marshal::StringToHGlobalAnsi(string)).ToPointer();

   returnstr;

   }

This function allows you to convert a .NET String to a const char* which you can further use in C++. If you want to do the conversion the other way around, things are not so complicated: the String class contains a constructor that accepts a const char* as a parameter.

Now, for the “sprers.eu”, we only have to define the constructor and the Move method. I have again added some console printing, but this time I used the .NET Console class to do so. Other than that, the only thing that has to be done in each method is to call its counterpart from the core project.

//sprers.eu

  #include "Entity.h"

  namespaceCLI

  {

   Entity::Entity(String^name,floatxPos,floatyPos)

   :ManagedObject(newCore::Entity(string_to_char_array(name),xPos,yPos))

   {

   Console::WriteLine("Creating a new Entity-wrapper object!");

   }

   voidEntity::Move(floatdeltaX,floatdeltaY)

   {

   Console::WriteLine("The Move method from the Wrapper was called!");

   m_Instance->Move(deltaX,deltaY);

   }

  }

An important thing to notice about the data types is that all the primitive types from C++ are compatible with their C# counterparts and therefore need no conversion in order to pass them from one context to another.

Apart from the .NET String to a C++ const char* conversion, you might find yourself in the position where you need to convert a .NET array to a C++ one. Even though they might look the same, there is a big difference between them: a .NET array is an object, while a C++ array is simply a pointer to the first element. I did not include any arrays in this example, but I will give you an example of a function that does the conversion:

staticvoidint_array_conversion(array<int>^data)

  {

   pin_ptr<unsignedint>arrayPin=&data[0];

   unsignedintsize=data->Length;

  }

I chose to create the example with an integer array, but you can replace int with any type that you need. However, I recommend writing the code for this conversion wherever you need it rather than using a function like this, since, as you can see, there are two components that you need to error c2512 c+ + mfc for the unmanaged array: the pointer to the first element and the number of elements, error c2512 c+ + mfc. You can, of course, create a struct to hold both of these elements, but it is a simpler and more elegant solution to just write these two lines of code for nvidia system error install archives failed separate case where you need to.

Creating a C# sandbox project

The last part of this tutorial is to create a C# project and test whether we are able to access the C++ functionality or not. Right-click the solution and add a new C# console application; I have called it Sandbox.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\create_sprers.eu

After that, add a reference from the Sandbox project to the Wrapper, the same way you did earlier.

We are now ready to code a C# test; we can easily check the result by looking at the text that will be printed in the console.

C:\Users\mirce\AppData\Local\Microsoft\Windows\INetCache\sprers.eu\sandbox_sprers.eu

usingSystem;

  usingCLI;

  namespaceSandbox

  {

      classProgram

      {

          staticvoidMain(string[]args)

          {

              Entitye=newEntity("The Wallman",20,35);

              sprers.eu(5,);

              sprers.euine(sprers.euion+" "+sprers.euion);  

              sprers.eu();        

   }

      }

  }

We are able to easily create a new Entity object – which is the Entity from the Wrapper project, not the one from the Core – and access zsh config log error methods and properties that is has to offer. Before running the project, make sure to right click on it in the Solution Explorer, and choose &#;Set as startup project&#.

An interesting thing that error c2512 c+ + mfc might notice in the console is that the showmessage error delphi Entity object is created before the wrapper Entity object – this is actually an illusion created by the console-printing, since the superclass constructor from the wrapper Entity object is called before the Console::WriteLine method is called.

Conclusion

The example that I developed for this article is very basic, as the main purpose of the article was to show you the architecture that is involved in a C++/CLI wrapper. If you wonder why you would ever use this technology for something as simple as accessing and changing two variables, the answer is that you should not. I mentioned game engines as a main candidate for using a wrapper several times in this article, because this is the example that I am most familiar with, but it is not the only acceptable case. However, you should spend some time taking all the possible solutions into consideration before deciding to use C++/CLI instead of just C#: Does it really increase the performance of your software? Is the Garbage Controller really hurting the memory usage of your program so much that you need to handle it yourself? There are many such questions that may appear along the way, so I suggest documenting a lot about the technologies that you are using in your project before deciding to introduce a C++/CLI wrapper into it.

    Thanks Krishnaa. As far as I remember, I didn't change anything. I've attached part of my project source in this post, as the whole project is too big.

    I just found another thing which might cause the problem. Need your advice. I see from the debug assertion error c2512 c+ + mfc, it comments: invlaid dialog templates. SO I thought this might be the problem.

    Initially, I have a formview called "IDD_TACTILEVIEWERDLG_FORM". But then I don't want it and I deleted it in resource.h
    "#define IDD_TACTILEVIEWERDLG_FORM "

    and commented in view.h: essbase error 1019002 //{{AFX_DATA(CTactileViewerDlgView)
    enum{ IDD = IDD_TACTILEVIEWERDLG_FORM };
    //}}AFX_DATA

    and commented the ": CFormView(CTactileViewerDlgView::IDD)" in sprers.eu:
    // CTactileViewerDlgView construction/destruction
    CTactileViewerDlgView::CTactileViewerDlgView()
    : CFormView(CTactileViewerDlgView::IDD)
    {
    //{{AFX_DATA_INIT(CTactileViewerDlgView)
    //}}AFX_DATA_INIT
    }

    Then it shows the error when I build it:
    error C 'CFormView' : no appropriate default constructor available

    Thanks, error c2512 c+ + mfc.

    I think that's what I'm doing actually

    {//Code}

    CSentenceList::~CSentenceList ()

    Jon
    Make sure you have the equivalent of a default destructor by giving the parameters of your constructor default values. "C++ will not attempt to create a default constructor for you if you declare one" (Effective C++ Third Edition - Scott Meyers)

    Try this in your declaration in the header file
    CSentenceList(bool bCreateArray=false);


    I tried adding a default value, even in the base class, but it's still unsuccessful.

    CSentenceList::CSentenceList(bool bCreateArray = false) : CSentenceArray(bCreateArray = false)
    {int x = NULL;}

    CSentenceList::~CSentenceList ()
    {}


    Jon
    No, your putting it in the implementation section.

    Put it only in the declaration in the header file.

    Not per the code you've shown. The compiler is telling you exactly what the problem is. has no default constructor.

    Copy Code

    You have declared a function called in the class. I suspect this is hiding the class constructor. Remove or rename this function, I'm pretty sure this is illegal anyway and you're just getting a poor diagnostic message from the compiler.

    Stability. What an interesting concept. -- Chris Maunder
    Thats just passing the parameter to the base class which is correct, otherwise the base class will not get any parameters to initialize with. The class declaration shows CSentenceList is derived from CSentenceArray

    class CSentenceList :
    // Sentences stored as a linked list

    you'd better check the class CSink and make sure that
    the CSink impliment all the virtual functions whose it's drivied from



    hi
    An abstract class is one that has one or more pure virtual functions defined. The intent is that you derive from that class and provide actual implementations for each of these functions. You can't instantiate a class that has a pure virtual function defined (since if you called it, the computer wouldn't knnow what to do) so the error message you're getting indicates that you've missed (at least) one.

    yeah i have overridden all the pure virtual function`s in the derived class,and wrote their implementation,even then i am getting error..
    You have to check all the way up the hierarchy. Maybe you're deriving from a class that is derived from a class that is derived from a class that still has a pure virtual function Smile   [Coffee]

    Make sure that your OnSize handler is calling the default implementation also.
