Validation functions do not change input values in any way, so to avoid data type conversion, use one or more validator functions instead of a data type to restrict the input. For example: To avoid conversion of
Events enable a class or object to notify other classes or objects when something of interest occurs. The publisher is the class that defines and raises the event, while the subscribers are the classes that attach methods to handle the event. In C#, the event keyword is used to declare an...
class_name The actual name of the class. Remarks The framework uses this ability to create new objects dynamically. For example, the new view created when you open a new document. Document, view, and frame classes should support dynamic creation because the framework needs to create them dynami...
In this paper, we address these problems from a theoretical angle. More specifically, we define the class of Target-Branched Declare constraints and investigate the formal properties it exhibits. Furthermore, we present a technique for the efficient discovery of compact Target-Branched Declare models...
What it Means to Define Something in C and C++ Defining something means providing all of the necessary information to create that thing in its entirety. Defining a function means providing a function body; defining a class means giving all of the methods of the class and the fields. Once som...
include the definition for a DLL function in your project. A Declare statement in a standard module can be public or private, depending on whether you want the API function to be available only to a single module or to the entire project. In a class module, a Declare statement must be ...
What it Means to Declare Something in C and C++ When you declare a variable, a function, or even a class all you are doing is saying: there is something with this name, and it has this type. The compiler can then handle most (but not all) uses of that name without needing the ful...

Non-static variables that belong to a specific instance (or object) of a class are called instance variables in C++. These variables are defined within a class but outside of any methods, functions, or blocks. They are created when an object of the class is instantiated and destroyed when ...
