CS360/CS580H GUI & Windows Programming

Outline Win32/Windows API & SDK Visual Studio MFC – Microsoft Foundation Classes C# &.NET – concepts Windows Forms WPF - Windows Presentation Foundation (DirectX+XAML based) RTL included (post-Vista) WPF controls are OK in a WinForms app & vice-versa – This is a 2 nd API (based on.NET 2.0)

Win32 = Windows API Basic windows functions Messages from use/system – (mouse-click, close, etc.) Usable with C/C++ Programmer must do almost everything Used with the Windows SDK

WinAPI Programs WinMain – Primary entry point from OS – 3 parts Procedure definition Init Message processing loop WinProc – Performs actions to process messages

Windows Messages Mechanism for system/user event triggering Requires a "callback" mechanism – O/S calls your functions – Reverse of a "system call" Message processing loop in program – Tests for message types – Calls your handler functions Program is idle until an event

Windows Forms GUI part of.NET Framework Does not offer a paradigm comparable to Model– View–Controller of C++ with MFCModel– View–Controller Event driven

MFC A class library Contains portions of the Win32API Classes contain pre-written code to do things like: – Create/Open/close a window – Open a dialog box – Independent of user settings

MFC programs InitInstance – Primary entry point _tWinMain WndProc

WPF ( Windows Presentation Foundation) (V4.5 – Aug 2012 – may be the last version) 1 st release in 2005 Implements SOAP & non-MS web svc's tech's. DirectX vs. older GDI interface XAML (based on XML) Standalone apps Embedded objects on a website RTL included in all Windows post-XP Unifies – Rendering, typography, vector graphics, animation, fixed, adaptive & pre-rendered docs, events, bindings Poor response-time, not for low-power devices

What is.NET From MS, “.NET is the Microsoft Web services strategy” for connecting programs, people, devices, etc. 4 components: – Common Language Specification (CLS) – Framework Class Library (FCL) – Common Language Runtime (CLR) –.NET Tools

Common Language Specification – Provides a consistent means for inter-language communication – Allows sub-components to be in different languages, e.g.; C#, VB.Net, J#, F#, Managed C++
