In this paper we describe a Python- and Tkinter-based visual-programming environment called ViPEr. This tool enables non-programmers to build computational and visualization networks interactively. Computational nodes can be placed onto a canvas and their input and output ports can be connected using the mouse. The connections between the nodes define a directed graph that will be used to propagate data and trigger the execution of nodes that have new input data. ViPEr is, in appearance, similar to programs such as AVS [Upson et al. 89] from Advanced Visual Simulations Inc, or OpenDX [DX 93] from IBM, but presents some fundamental differences which will be pointed out throughout this paper. Several examples of applications will be used to illustrate ViPEr’s design and current range of capabilities.

Although Python is a high-level language, it is not English or some other natural human language. The Python translator does not understand “add the numbers two and three”. Python is a formal language with its own specific rules and formats, which these tutorials will introduce gradually, at a pace intended for a beginner. These tutorials are also appropriate for beginners because they gradually introduce fundamental logical programming skills. Learning these skills will allow you to much more easily program in other languages besides Python. Some of the skills you will learn are

Considering the rapid pace of changes in the software field and the limited courses that a student can take in languages, the question is which languages are crucial for students to learn in an undergraduate IS curriculum. This paper investigates the necessity of teaching C# and .NET in the undergraduate IS curriculum. It explores the pros and cons of .Net versus J2EE for applications development and differences between C#, C++ and Java, and which one may be the best language for teaching first programming course in IS curriculum.

This paper explains our efforts to add Ada to Microsoft’s family of .NET languages. There are several advantages to weaving Ada into the Common Language Environment provided by the .NET environment. This paper explains our approach and current progress on the research. We provide the means to extract Ada specification files from Microsoft Intermediate Language (MSIL) code and compile Ada programs into MSIL.

One of the great benefits of using Oracle products is their support for multiple programming frameworks. By supporting .NET, Java/J2EE, PHP, and C/C++ applications, all developers can use Oracle’s advanced database features, providing true flexibility for development organizations. Each of Oracle’s data access drivers is designed to maximize performance of its respective framework and to enable access to the latest database features.

Crystal Reports has enjoyed a long association with Microsoft and has shipped with Visual Basic (and subsequently Visual Studio) as the default report writer since 1993. Developers have traditionally had a love-hate relationship with Crystal Reports; they loved the functionality it provided and the free run-time license, but they hated having to upgrade to the latest version to get the features they required. Another complaint was that reports could not be created or modified programmatically; they could be created only through the user interface (UI) with either the developer UI with Visual Studio or the consumer UI with the Crystal Reports retail package.
