  • Programming with Windows Forms
    A P P E N D I X A ■ ■ ■ Programming with Windows Forms Since the release of the .NET platform (circa 2001), the base class libraries have included a particular API named Windows Forms, represented primarily by the System.Windows.Forms.dll assembly. The Windows Forms toolkit provides the types necessary to build desktop graphical user interfaces (GUIs), create custom controls, manage resources (e.g., string tables and icons), and perform other desktop- centric programming tasks. In addition, a separate API named GDI+ (represented by the System.Drawing.dll assembly) provides additional types that allow programmers to generate 2D graphics, interact with networked printers, and manipulate image data. The Windows Forms (and GDI+) APIs remain alive and well within the .NET 4.0 platform, and they will exist within the base class library for quite some time (arguably forever). However, Microsoft has shipped a brand new GUI toolkit called Windows Presentation Foundation (WPF) since the release of .NET 3.0. As you saw in Chapters 27-31, WPF provides a massive amount of horsepower that you can use to build bleeding-edge user interfaces, and it has become the preferred desktop API for today’s .NET graphical user interfaces. The point of this appendix, however, is to provide a tour of the traditional Windows Forms API. One reason it is helpful to understand the original programming model: you can find many existing Windows Forms applications out there that will need to be maintained for some time to come. Also, many desktop GUIs simply might not require the horsepower offered by WPF.

  • Appendixes APPENDIX A
    PART 8 Appendixes APPENDIX A COM and .NET Interoperability The goal of this book was to provide you with a solid foundation in the C# language and the core services provided by the .NET platform. I suspect that when you contrast the object model provided by .NET to that of Microsoft’s previous component architecture (COM), you’ll no doubt be con- vinced that these are two entirely unique systems. Regardless of the fact that COM is now considered to be a legacy framework, you may have existing COM-based systems that you would like to inte- grate into your new .NET applications. Thankfully, the .NET platform provides various types, tools, and namespaces that make the process of COM and .NET interoperability quite straightforward. This appendix begins by examin- ing the process of .NET to COM interoperability and the related Runtime Callable Wrapper (RCW). The latter part of this appendix examines the opposite situation: a COM type communicating with a .NET type using a COM Callable Wrapper (CCW). ■Note A full examination of the .NET interoperability layer would require a book unto itself. If you require more details than presented in this appendix, check out my book COM and .NET Interoperability (Apress, 2002). The Scope of .NET Interoperability Recall that when you build assemblies using a .NET-aware compiler, you are creating managed code that can be hosted by the common language runtime (CLR). Managed code offers a number of ben- efits such as automatic memory management, a unified type system (the CTS), self-describing assemblies, and so forth. As you have also seen, .NET assemblies have a particular internal compo- sition.
