The previous sample illustrated a portion of COM's infrastructure for creating instances of objects. In order to make our object a real COM object, only minor details are missing: Allow reference counting on our exposed interfaces. Allow multiple interfaces on an object. Use the standard IClass...
Object-oriented programming in C++ syntax involves creating classes that encapsulate data and functions, and objects that are instances of those classes. Inheritance, polymorphism and encapsulation are some of the key features of object-oriented programming that are supported in C++. Templates are anothe...
It is convenient to useCoCreateInstancewhen you need to create only a single instance of an object on the local machine. If you are creating an instance on remote machine, call CoCreateInstanceEx. When you are creating multiple instances, it is more efficient to obtain a pointer to the class ...

4. It is possible to have multiple instances of an object to co-exist with out any interference. 5. It is easy to partition the work in a project based on objects. 6. Object-oriented systems can be easily upgraded from small to large systems. ...
Objects passed in as template arguments have the type const T, where T is the type of the object, and has static storage duration.struct foo { foo() = default; constexpr foo(int) {} }; template <foo f> auto get_foo() { return f; } get_foo(); // uses implicit constructor get...
The callback functions you write need to be static functions, and you need to use ClientData arguments or pointers to class instances if you want to execute method calls of objects. Assign the address of your callback function to the class pointer data item specified in this table in order...

When the header filefile.hwas generated for C++, then this command generates a couple of C++ source files (more details will follow in Section9) that implement XML encoders for the data binding. Option-igenerates a client proxy objects and service objects to invoke and serve SOAP/XML operati...
The bug was fixed, that the identifiers ofnamespaceswere missing for the first parameters in nested functions and for base classes of objects. 05/08/2011 Version 1.4.7 Complete Delphi projects can be converted to C++Builder projects now withDelphi2Cppat once, provided that the Delphi dpr-file...
