  • 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.

  • Diploma Thesis
    Faculty of Computer Science Chair for Real Time Systems Diploma Thesis Porting DotGNU to Embedded Linux Author: Alexander Stein Supervisor: Jun.-Prof. Dr.-Ing. Robert Baumgartl Dipl.-Ing. Ronald Sieber Date of Submission: May 15, 2008 Alexander Stein Porting DotGNU to Embedded Linux Diploma Thesis, Chemnitz University of Technology, 2008 Abstract Programming PLC systems is limited by the provided libraries. In contrary, hardware-near programming needs bigger eorts in e. g. initializing the hardware. This work oers a foundation to combine advantages of both development sides. Therefore, Portable.NET from the DotGNU project has been used, which is an im- plementation of CLI, better known as .NET. The target system is the PLCcore- 5484 microcontroller board, developed by SYS TEC electronic GmbH. Built upon the porting, two variants to use interrupt routines withing the Portabe.NET runtime environment have been analyzed. Finally, the reaction times to occuring interrupt events have been examined and compared. Die Programmierung für SPS-Systeme ist durch die gegebenen Bibliotheken beschränkt, während hardwarenahe Programmierung einen gröÿeren Aufwand durch z.B. Initialisierungen hat. Diese Arbeit bietet eine Grundlage, um die Vorteile bei- der Entwicklungsseiten zu kombinieren. Dafür wurde Portable.NET des DotGNU- Projekts, eine Implementierung des CLI, bekannter unter dem Namen .NET, be- nutzt. Das Zielsystem ist das PLCcore-5484 Mikrocontrollerboard der SYS TEC electronic GmbH. Aufbauend auf der Portierung wurden zwei Varianten zur Ein- bindung von Interrupt-Routinen in die Portable.NET Laufzeitumgebung untersucht. Abschlieÿend wurden die Reaktionszeiten zu eintretenden Interrupts analysiert und verglichen. Acknowledgements I would like to thank some persons who had inuence and supported me in my work.

  • Comparative Studies of Six Programming Languages
    Comparative Studies of Six Programming Languages Zakaria Alomari Oualid El Halimi Kaushik Sivaprasad Chitrang Pandit Concordia University Concordia University Concordia University Concordia University Montreal, Canada Montreal, Canada Montreal, Canada Montreal, Canada [email protected] [email protected] [email protected] [email protected] Abstract Comparison of programming languages is a common topic of discussion among software engineers. Multiple programming languages are designed, specified, and implemented every year in order to keep up with the changing programming paradigms, hardware evolution, etc. In this paper we present a comparative study between six programming languages: C++, PHP, C#, Java, Python, VB ; These languages are compared under the characteristics of reusability, reliability, portability, availability of compilers and tools, readability, efficiency, familiarity and expressiveness. 1. Introduction: Programming languages are fascinating and interesting field of study. Computer scientists tend to create new programming language. Thousand different languages have been created in the last few years. Some languages enjoy wide popularity and others introduce new features. Each language has its advantages and drawbacks. The present work provides a comparison of various properties, paradigms, and features used by a couple of popular programming languages: C++, PHP, C#, Java, Python, VB. With these variety of languages and their widespread use, software designer and programmers should to be aware

  • J2EE and .Net Security
    J2EE and .Net security 1. Introduction 1.1. Document Revision History Author Document Last Modified Note Version Date Ger Mulcahy 1.2 12/02/2002 Third draft Ger Mulcahy 1.1 01/02/2002 Added information on JAAS, JSSE, Project Liberty, DotGNU, etc. Ger Mulcahy 1.0 21/01/2002 Second Draft – added contributors Ger Mulcahy 0.1 04/01/2002 First draft 1.1.1. Contributors My thanks to the following for their assistance with this article: Alan Danziger, Mark Curphey, Alan Faber, Elias Levy, Tony Northrup 1.2. Overview A number of general comparative articles have been written discussing the pros and cons of these two competing technological platforms. The intention of this paper is to discuss J2EE and .Net at a high level from a security perspective, examining the tools and methodologies the platforms use to provide secure development and deployment environments. This introduction section covers a brief, incomplete discussion of key features of both platforms. It will not discuss areas that are not analogous between platforms. For more information on both, see the references section of this document. Note that .Net is a product platform, whereas J2EE is a standard specification, which is implemented to varying degrees of fidelity by a number of vendors. For this reason, direct comparisons may be difficult in certain areas without going into vendor specifics. For the purposes of this article no real distinction is made between .Net and the .Net Framework, which forms one part of the .Net strategy. While Microsoft is pushing .Net as their strategy for Web Services, this document will not discuss the two platforms from the point of view of Web Services, nor does it describe COM+, as this is not part of the .Net Framework.

  • Unsupervised Translation of Programming Languages
    Unsupervised Translation of Programming Languages Marie-Anne Lachaux∗ Baptiste Roziere* Lowik Chanussot Facebook AI Research Facebook AI Research Facebook AI Research [email protected] Paris-Dauphine University [email protected] [email protected] Guillaume Lample Facebook AI Research [email protected] Abstract A transcompiler, also known as source-to-source translator, is a system that converts source code from a high-level programming language (such as C++ or Python) to another. Transcompilers are primarily used for interoperability, and to port codebases written in an obsolete or deprecated language (e.g. COBOL, Python 2) to a modern one. They typically rely on handcrafted rewrite rules, applied to the source code abstract syntax tree. Unfortunately, the resulting translations often lack readability, fail to respect the target language conventions, and require manual modifications in order to work properly. The overall translation process is time- consuming and requires expertise in both the source and target languages, making code-translation projects expensive. Although neural models significantly outper- form their rule-based counterparts in the context of natural language translation, their applications to transcompilation have been limited due to the scarcity of paral- lel data in this domain. In this paper, we propose to leverage recent approaches in unsupervised machine translation to train a fully unsupervised neural transcompiler. We train our model on source code from open source GitHub projects, and show that it can translate functions between C++, Java, and Python with high accuracy. Our method relies exclusively on monolingual source code, requires no expertise in the source or target languages, and can easily be generalized to other programming languages.
