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.

The security of information systems is a wide area. Its development followed that of information systems, whose development in turn followed advances in hardware. As computers and software have developed real fast: “To put it quite bluntly: as long as there were no machines, programming was no problem at all; when we had a few weak computers, programming became a mild problem, and now we have gigantic computers, programming had become an equally gigantic problem.” [1], so have developed the possibilities for security breaches.

Microsoft’s Visual Studio 2008 introduces a whole new set of .NET technologies that will revolutionize, once again, the way you develop smart client and web-based applications; the most notable being LINQ, WPF and, of course, Silverlight. For most of us working in and around web application development in the business world, Silverlight is a big step forward; especially if you consider that it provides clean coding practices with extensible languages (e.g. XAML and C#). It also provides some of Visual Studio’s rich programming model that we have become accustomed to and can no longer live without; such as class libraries, debugging capabilities and IntelliSense among many others.

Please note: this manual is a self-training guide. We advise you to refer to the online help when you are using WinDev Mobile. The aim of the tutorial is to help you discover WinDev Mobile, get to know the editors and teach you the WinDev Mobile basics. It does not cover all the features of WinDev. Mobile

This guide is intended for developers with experience of the standard WinDev and who know how to handle a Pocket PC. It only describes the concepts specifically for developing an application for Pocket PC.

The Microsoft .NET software platform integrates various aspects of software development. In .NET applications can be written in a variety of programming languages and can be either stand-alone or web-based. A lab module for CS 453 Electronic Commerce Technologies was developed that instructs students on how to develop complex e-commerce websites using the programming language C# within the Microsoft .NET framework. This project and thesis provided insight into the power of C# and the .NET framework. Student evaluations were constructive and positive overall. There were many good suggestions for expansion of the C# lab module.

An emerging trend in Social Networking sites and Web portals is the opening up of their APIs to external application develop- ers. For example, the Facebook Platform, Google Gadgets and Yahoo! Widgets allow developers to design their own applications, which can then can be integrated with the platform and shared with other users. However, current APIs are targeted towards develop- ers with programming expertise and database knowledge; they are not accessible to a large class of users who do not have a programming/database background, but would nevertheless like to create new applications. To address this need, we have developed the AppForge system, which provides a WYSIWYG application development platform. Users can graphically specify the components of webpages inside a Web browser, and the corresponding database schema and application logic will be automatically generated on the fly by the system.

Many software developers are attracted to the idea of aspect-oriented programming (AOP) but unsure about how to begin using the technology. They recognize the concept of crosscutting concerns, and know that they have had problems with the implementation of such concerns in the past. But there are many questions about how to adopt AOP into the development process.
