With the help of Windows Forms, the .NET Framework provides a more comprehensive abstraction above the Win32 API than Visual Basic or MFC did. [9] Windows Forms is similar to Microsoft Foundation Class (MFC) library in developing client applications. It provides a wrapper consisting of a set of C++ classes for development of Windows applications.
QtSharp, C# wrappers around the Qt widget toolkit, which is itself based-on the C++ language. Windows Forms. There is an original Microsoft's implementation that is a wrapper around the Windows API and runs on windows, and Mono's alternative implementation that is cross platform.
These extensions were created by Microsoft to allow C++ code to be targeted to the Common Language Runtime (CLR) in the form of managed code, as well as continue to interoperate with native code. In 2004, the Managed C++ extensions were significantly revised to clarify and simplify syntax and expand functionality to include managed generics.
Classes are defined for many of the handle-managed Windows objects and also for predefined windows and common controls. At the time of its introduction, MFC provided C++ macros for Windows message-handling (via Message Maps [ 9 ] ), exceptions , run-time type identification (RTTI), serialization and dynamic class instantiation.
VCL components cover Windows controls like windows (TForm class), controls (e.g., TButton, TCheckBox, TLabel classes) as well as database access (e.g., ADO or IBX components) or Internet connections (Indy components). The component approach allows programmers to extend the VCL with many visual and non-visual additional components.
Visual C++ can also use the Visual Studio forms designer to design UI graphically. Visual C++ can also be used with the Windows API. It also supports the use of intrinsic functions, [41] which are functions recognized by the compiler itself and not implemented as a library. Intrinsic functions are used to expose the SSE instruction set of ...
Complex PTSD is a form of PTSD that can develop in people who experience ongoing or long-term trauma or multiple traumas. This may include: Childhood abuse or neglect. Domestic violence.
A VBX is a packaged extension in the form of a dynamic-link library (DLL) that allows objects to be graphically placed in a form and manipulated by properties and methods. These were later adapted for use by other languages such as Visual C++. In 1992, with Windows 3.1, Microsoft released OLE 2 with its new underlying object model, COM.
