Use Cases

Mobile Application• 6 <CXP/> files• Each around 40 lines of code

Dynamic Web Page• One <CXP/> page per view• Contains HTML mixed with code

Web Application (like uservoice.com):• 8 views (<CXP/>), 2 controllers (prg), 7 models

(prg)• <1000 lines of code

Forms, Image Creation (Add here your or your customer‘sdemands…)


Intro (What‘s the idea behind it!)

<CXP/>:– can create dynamic and interactive web pages/content– is a powerful alternative to ASP.NET and PHP– „speaks“ the language Visual FoxPro, FoxPro and Xbase++ developers know– executes native code, whereas ASP/PHP is interpreted

Intermediate Code:

Hello.cxp:


Intro


Features (1/2)

• Edit and run• Compiler error messages with great detail

Easy to Use

• Executes compiled native code versus interpreted code• Uses random distribution on multi-core servers• Dynamic I/O chunking for large data upload/download• Developer can use threads to offload work or even defer results

Very Fast

• Code injection doesn‘t work as it executes compiled code• AES encryption comes with Xbase++• Ready-to-use authentication and user account management

(RBAC) included

Secure


Features (2/2)

• Application configuration management• Interceptors for flow control• Caching to avoid repeated data gathering• WebSockets for peer-to-peer connects• Ajax with XML and JSON right out of the box

Feature-Rich and Innovative

• Native IIS and Apache• FastCGI for interfacing with literally any web server

• No limits• Open, full access to any language extension• Customizable, you can create your own commands• No runtime fees, no per-site or per-CPU fees

Full Xbase++ 2.0 Language


Some Features in Detail

Error Management Builder, compiler and linker all generate well- documented

error messages

Code Locality Allows you to implement page-global functionality, add

classes or just to structure your code

Session/Page/Application/Site Data Persistence engine for any runtime data type

Content Types By default, pages return HTML content But can return anything you want

Images, PDF files Binary data XML / JSON

Dynamic Image


jQuery UI

There are many HTML/UI Javascriptframeworks out there! We decided to go with jQuery: Best architecture Easy to hide (we don‘t like Javascript)

Good datasource binding

Index

Grid

Suppliers


MobileApp

Different form factors require specific UI Don‘t try to re-create a desktop form on a

smartphone Sample uses Dojo as the UI Implementation consists of: 6 <CXP/> pages Each has around 40 lines of code Data is from dbf tables Image data from table needs to be transformed for

mobile device

Summary

With <CXP/>, you can develop Connected Mobile or Web applications

Use <CXP/> pages for dynamic Web pages or smallMobile apps.

Use MVC2 (controller/model)-based Web applicationstogether with views for larger projects with complexbusiness logic and data model

Any FoxPro, Visual FoxPro or Xbase++ developer canleverage existing knowledge to create Web or Mobile applications


Call For Action Join the CTP, influence the future of your tool chain Start developing Web or Connected Mobile applications, just think

about the added value for your existing VFP solution Actively promote <CXP/> to any other Visual FoxPro, FoxPro

developer out there With the forthcoming CTP and the release of Xbase++ 2.0, you can

proove to any manager that your skills your experience your language Your existing source codeAll have a future beyond MS. The FoxPro language is not dead!

Think about that: MS dumped Visual FoxPro as a tool But the language moves forward! Differentiate between the tool and the language!
