Use Ajax support just by writing standard Delphi/C++ code.
IntraWeb is for Weblications - A Weblication is a web application. Building a weblication is very different from building a web site, and IntraWeb is the first and only tool specifically geared towards creating weblications. This allows you to build weblications faster and easier. Based on a powerful HTML rendering engine, IntraWeb allows developers to design weblications in the same way as they would normal Windows applications. Using a drag and drop approach, developers can drop controls on forms (which can be thought of as a combination between HTML pages and forms), create events and set properties. The code behind the application is pure C#, Visual Basic, Delphi, C++, or Java, and does not require any knowledge of HTML or JavaScript.
