  • Eagle: Tcl Implementation in C
    Eagle: Tcl Implementation in C# Joe Mistachkin <[email protected]> 1. Abstract Eagle [1], Extensible Adaptable Generalized Logic Engine, is an implementation of the Tcl [2] scripting language for the Microsoft Common Language Runtime (CLR) [3]. It is designed to be a universal scripting solution for any CLR based language, and is written completely in C# [4]. Su- perficially, it is similar to Jacl [5], but it was written from scratch based on the design and imple- mentation of Tcl 8.4 [6]. It provides most of the functionality of the Tcl 8.4 interpreter while bor- rowing selected features from Tcl 8.5 [7] and the upcoming Tcl 8.6 [8] in addition to adding en- tirely new features. This paper explains how Eagle adds value to both Tcl/Tk and CLR-based applications and how it differs from other “dynamic languages” hosted by the CLR and its cousin, the Microsoft Dy- namic Language Runtime (DLR) [9]. It then describes how to use, integrate with, and extend Ea- gle effectively. It also covers some important implementation details and the overall design phi- losophy behind them. 2. Introduction This paper presents Eagle, which is an open-source [10] implementation of Tcl for the Microsoft CLR written entirely in C#. The goal of this project was to create a dynamic scripting language that could be used to automate any host application running on the CLR. 3. Rationale and Motivation Tcl makes it relatively easy to script applications written in C [11] and/or C++ [12] and so can also script applications written in many other languages (e.g.

    04_596985 ch01.qxp 12/14/05 7:46 PM Page 1 Initial Phases of a Web Request Before the first line of code you write for an .aspx page executes, both Internet Information Services (IIS) and ASP.NET have performed a fair amount of logic to establish the execution context for a HyperText Transfer Protocol (HTTP) request. IIS may have negotiated security credentials with your browser. IIS will have determined that ASP.NET should process the request and will perform a hand- off of the request to ASP.NET. At that point, ASP.NET performs various one-time initializations as well as per-request initializations. This chapter will describe the initial phases of a Web request and will drill into the various security operations that occur during these phases. In this chapter, you will learn about the following steps that IIS carries out for a request: ❑ The initial request handling and processing performed both by the operating system layer and the ASP.NET Internet Server Application Programming Interface (ISAPI) filter ❑ How IIS handles static content requests versus dynamic ASP.NET content requests ❑ How the ASP.NET ISAPI filter transitions the request from the world of IIS into the ASP.NET world Having an understandingCOPYRIGHTED of the more granular portions MATERIAL of request processing also sets the stage for future chapters that expand on some of the more important security processing that occurs during an ASP.NET request as well as the extensibility points available to you for modifying ASP.NET’s security behavior. This book describes security behavior primarily for Windows Server 2003 running IIS6 and ASP.NET.

THE RElAtiONSHiP OF C# tO .NET This book emphasizes that the C# language must be considered in parallel with the .NET Framework, rather than viewed in isolation. The C# compiler specifically targets .NET, which means that all code written in C# always runs using the .NET Framework. This has two important consequences for the C# language: 1. The architecture and methodologies of C# reflect the underlying methodologies of .NET. 2. In many cases, specific language features of C# actually depend on features of .NET or of the .NET base classes. Because of this dependence, you must gain some understanding of the architecture and methodology of .NET before you begin C# programming, which is the purpose of this chapter.

  • 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.
