Introduction to Managed Code
McGrath.book Page 89 Thursday, December 7, 2006 10:04 AM 3 Introduction to Managed Code Technology is dominated by two types of people: those who understand what they do not manage, and those who manage what they do not understand. —PUTT’S LAW Topics Covered in This Chapter What Is Managed Code? Introduction to Object-Oriented Programming Exploring the .NET Framework VSTO and Managed Code Summary Review Questions What Is Managed Code? Code that runs within the .NET Framework is considered managed code. This includes applications written in languages such as Visual C# and Visual Basic 2005. Code that is not managed by the .NET Frame- work is typically referred to as unmanaged code. This includes applica- tions written in programming languages such as C++, Visual Basic 6.0, and VBA. All Office solutions created using VSTO are written in managed code. VSTO supports both Visual Basic 2005 and Visual C#; however, we refer only to Visual Basic 2005 in text and in code examples in this book 89 McGrath.book Page 90 Thursday, December 7, 2006 10:04 AM 90 Chapter 3 Introduction to Managed Code because we believe it is easier to transition from VBA to Visual Basic 2005. Keep in mind that there is much to learn about the .NET Frame- work and managed code; this chapter only scratches the surface. Following are some benefits of using managed code: • Improved security. Often, security permissions are enabled or disabled by end users or determined by the identity of the user who is attempting to run code. However, code managed by the .NET Framework uses the security model code access security (CAS), which is based on the code’s identity and location. -

INTRODUCTION TO .NET FRAMEWORK NET Framework .NET Framework is a complete environment that allows developers to develop, run, and deploy the following applications: Console applications Windows Forms applications Windows Presentation Foundation (WPF) applications Web applications (ASP.NET applications) Web services Windows services Service-oriented applications using Windows Communication Foundation (WCF) Workflow-enabled applications using Windows Workflow Foundation (WF) .NET Framework also enables a developer to create sharable components to be used in distributed computing architecture. NET Framework supports the object-oriented programming model for multiple languages, such as Visual Basic, Visual C#, and Visual C++. NET Framework supports multiple programming languages in a manner that allows language interoperability. This implies that each language can use the code written in some other language. The main components of .NET Framework? The following are the key components of .NET Framework: .NET Framework Class Library Common Language Runtime Dynamic Language Runtimes (DLR) Application Domains Runtime Host Common Type System Metadata and Self-Describing Components Cross-Language Interoperability .NET Framework Security Profiling Side-by-Side Execution Microsoft Intermediate Language (MSIL) The .NET Framework is shipped with compilers of all .NET programming languages to develop programs. Each .NET compiler produces an intermediate code after compiling the source code. 1 The intermediate code is common for all languages and is understandable only to .NET environment. This intermediate code is known as MSIL. IL Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). All .NET source code is compiled to IL. IL is then converted to machine code at the point where the software is installed, or at run-time by a Just-In-Time (JIT) compiler. -

Embedding Mono Code in Unmanaged Applications on GNU/Linux
Embedding Mono code in unmanaged applications on GNU/Linux LTH School of Engineering at Campus Helsingborg Department of Computer Science Bachelor thesis: Martin Arvidsson Viktor Hermansson c Copyright Martin Arvidsson, Viktor Hermansson LTH School of Engineering Lund University Box 882 SE-251 08 Helsingborg Sweden LTH Ingenj¨orsh¨ogskolan vid Campus Helsingborg Lunds universitet Box 882 251 08 Helsingborg Printed in Sweden Media-Tryck Biblioteksdirektionen Lunds universitet Lund 2011 Abstract In today's society more and more work is carried out with the help of dif- ferent computer systems. To benefit from the data, integration between the systems is needed. Saab has developed a solution to the problem, by the name WISE. With a modular design costs can be minimized, because a new integration does not necessarily require new software, but can be achieved with configuration of an existing module. (a so-called driver). By supporting languages on a higher level than C++, development of new drivers can be speeded up to further decrease the costs. As a first step C# support was implemented with the help of C++/CLI. Such a solution is constrained to the Windows platform. To be able to meet the customers need for Linux compatibility this project was initiated, to create a wrapper driver with the help of Mono. In the report it is shown that it is fully possible to create a working embedding of C# with the Mono runtime. The documentation of the limited embedding-API is however inadequate, this resulted in us having to investigate the functionality by creating small test cases and read the source code to see how function calls behaved. -

This section provides you with the basic knowledge you need to get up and running with the most recent version of C#. Specifi cally, this chapter provides an overview of the .NET Framework and C#, including what these technologies are, the motivation for using them, and how they relate to each other. It begins with a general discussion of the .NET Framework. This technology contains many concepts that are tricky to come to grips with initially. This means that the discussion, by necessity, covers many concepts in a short amount of space. However, a quick look at the basics is essential to understanding how to program in C#. Later in the book, you revisit many of the topics covered here, exploring them in more detail. After that general introduction, the chapter provides a basic description of C# itself, includ- ing its origins and similarities to C++. -

Overview of the .NET Framework
7/3/2016 Overview of the .NET Framework Overview of the .NET Framework ﴿NET Framework ﴾current version. The .NET Framework is a technology that supports building and running the next generation of applications and XML Web services. The .NET Framework is designed to fulfill the following objectives: To provide a consistent object‐oriented programming environment whether object code is stored and executed locally, executed locally but Internet‐distributed, or executed remotely. To provide a code‐execution environment that minimizes software deployment and versioning conflicts. To provide a code‐execution environment that promotes safe execution of code, including code created by an unknown or semi‐trusted third party. To provide a code‐execution environment that eliminates the performance problems of scripted or interpreted environments. To make the developer experience consistent across widely varying types of applications, such as Windows‐based applications and Web‐based applications. To build all communication on industry standards to ensure that code based on the .NET Framework can integrate with any other code. Note For a general introduction to the .NET Framework for both users and developers, see Getting Started with the .NET Framework. To download the .NET Framework, see Installing the .NET Framework. The .NET Framework consists of the common language runtime and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework. You can think of the runtime as an agent that manages code at execution time, providing core services such as memory management, thread management, and remoting, while also enforcing strict type safety and other forms of code accuracy that promote security and robustness. -
1 Lecture #1 Introducing Visual C++ What Is C++? C++ Is a General
Lecture #1 Introducing Visual C++ What is C++? C++ is a general-purpose programming language created in 1983 by Bjarne Stroustrup. It is an enhanced version of the C programming which is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories and was originally created for developing applications to run in the Unix operating system. C++, as a direct descendant of C, preserved most fundamental features of the C programming language, yet C++ has many new features such as the ones that simplify memory management and garbage collection. C++ also has a much better support in object-oriented paradigm. Since its debut, C++ quickly became widely used in the software industry, and is possibly the most popular languages ever created. The following is a simple “console” program written in standard C++ to display a text “Hello world!” in the console screen. In computing, a “console” usually means a combination of a display monitor and an input device (usually a keyboard and mouse pair) which allows a user to input commands and receive visual output from a terminal device or computer system. #include <iostream> int main() { std::cout << "Hello world!"; } It is necessary to note that this course is not designed to discuss how to develop console applications using standard C++. This course will focus on developing simple Windows applications using Visual C++. What is Visual Visual C++ is a variation of the C++ language created and maintained by Microsoft as one of C++? the supported programming languages of the .NET Platform. As a member of Visual Studio, Microsoft’s IDE (integrated development environment) product, Visual C++ can build applications written in C, C++, and C++/CLI programming languages.
