r6025 pure virtual function call

It wasn't long before the program was written tonight, and the program did not report any errors or warning. However, after running the program, the image windows disappeared immediately and could not be displayed. The program was wasted for more than an hour and encountered a strange problem, finally, I changed my notebook to run it without modifying the program. It's totally correct! One problem reported during debugging is the first chance exception, sometimes there will be inexplicable

A pure virtual function is defined in the base class and implemented in the derived class. However, in some cases, errors such as r6025 runtime error and pure virtual function

I do not know why there is no problem in debugging when I am working on the cximage library in the internship unit, but a pure virtual function call error exists in the release version! What happened? Let's find out what happened! Description on msdn Http://forums.msdn.microsoft.com/zh-CN/clr/thread/bfa759a8-0cc0-4d6

Introduction has never written a conceptual article, because I think that these conceptual things are written in the books and are very detailed and useless, and today I have a whim to write, Here is a discussion of the virtual base class, virtual functions and pure virtual functions, a look at the name of the peopl

1: A class containing a pure virtual function is called an abstract class, and an abstract class has at least one pure virtual function. An abstract class can only be derived as a new subclass of a base class, not in a program (th

class, it inherits the virtual function of its base class. When the program discovers the virtual function name, it will automatically be used as a dynamic binder, which is to select the appropriate member function dynamically when the program is run.

Because both C + + and Java are object-oriented programming languages, their polymorphism is achieved by virtual functions and abstract functions, respectively.The virtual function of C + + can be overridden in subclasses, and the invocation is judged by the actual object, not by the pointer type (the invocation of the normal

virtual functions are defined in the base class for overload and polymorphism, and can be overridden or not written in a base class, even if the definition is null. pure virtual functions are not defined in the base class and must be implemented in subclasses, much like Java the interface function in.

virtual functions, you have to speak pure virtual functions: In C + +, you can declare a member function to be a pure virtual function, in syntax format:The

Normal member functions are statically compiled, with no run-time polymorphism, only based on the pointer or reference to the "literal" class object, call your own ordinary function; Virtual functions are defined in the base class for overload and polymorphism, even if the definition is null; a pure

Dynamically bound when called by polymorphic mode.3) For virtual functions, both the parent and child classes have their own versions. dynamically bound when called by polymorphic mode.4) realizes the subclass of

virtual function3, when there are virtual functions in the base class, the destructor of the general base class is also defined as the virtual destructor. If you do not define a virtual destructor, when you delete a pointer to a derived class object, the destructor for the base class is called, and the destructor for

the program, but it can automatically decide whether to call the Function2 in the base class or the Function2 in the inheriting class according to the user's input, which is the function of the virtual function. We know that in MFC, many classes are required you to inherit, their member functions are many to overload,

programmers often define the destructor of a base class as a virtual function. Because, after defining a destructor for a base class as a virtual function, the system invokes the destructor of the corresponding class when it deletes a pointer to the object defined by the derived class using Delete. Instead of defining
