Smart Client vs. Thin Client
Smart Client
Some business logic resides within the client
Logic updates require client redistribution
Offline processing
Synchronization required for data integration
Thin Client
All business logic is invoked from a server
Logic updates can occur without client redistribution
Online processing only
Synchronization is not required to ensure fresh data

21. Developing an Application
4 Main Steps
Application Design
Application Development
Application Testing
Application Deployment

22. Application Design This helps when porting to other platforms
Good UI is very important
More important than on the desktop?
Handheld <> desktop
No keyboard
Small screen
Platform differences
How do you squeeze lots of information onto a small screen?
Tab controls, menus, etc.
Iterative development
Keep application logic separate from GUI!
This helps when porting to other platforms

23. Application Development
Familiar IDE for PowerBuilder Developers
PowerBuilder Objects can be imported into Pocket PowerBuilder
Pocket PowerBuilder objects can be imported into PowerBuilder
Most development is visual
Drag and drop components and database access
Development Platforms
Windows 2000
Windows XP

24. Application Testing On the Desktop On a device Emulator
Testing can occur in three ways:
On the Desktop
Does not use the same VM, therefore not accurate representation of device
Good for quick testing early on
On a device Emulator
Uses Windows CE VM, but not for the same chipset as physical device
Pocket PC 2002 Emulator is decent
On the device itself
Best way to determine if application will work correctly at deployment
Can also test network connectivity at this point

25. Developing an Application
Test EVERY part of your application:
Device
Application
Network(s)
Synchronization
Integration with back-end …

26. Recommend using device with Remote observer application
Project Painter
Deployment Options *
CE Device (ARM only)
PPC 2000 Emulator
PPC 2002 Emulator
Desktop
Build CAB File
Version Information – Desktop only
Recommend using device with Remote observer application

27. Application Deployment
Pocket PC applications are often distributed as CAB files
Pocket PC SDK comes with ‘cabwiz’ which is a utility to package applications into self installing CAB files
Deployment techniques are being researched by Pocket PowerBuilder team
Deployment to multiple devices in remote locations can be facilitated by application deployment and management software

28. Packaging and Deployment
Overview
Generate a CAB file
Single package
Single Platform: “my_app.ARM.CAB”
Installed and Uninstalled
Basic level of User Deployment
Generate a “setup” program
The “my_setup.exe” which does everything.
Multiple CAB Files
Multiple Platforms
May Contain PK*.DLL redistributable files too
Easiest level for final customer
Pocket PB Helps You – Project Painter

29. Package For Deploy (CAB)
CAB file
Project Painter –
CheckBox: “Build CAB File for Distribution”
Generates “inf” file and runs “CabWiz” from Microsoft.
INF file is an ASCII text file
We leave the INF file and the BAT file around for your modification
Compatible with PPC-2003 standards
Uses Installation Directories
Uses Version Information fields
Company Name  “Provider Name”
Product Name  “Application Name”
Description  comment in header
Copyright  comment in header
Version  comment in header

30. Developing an Application
PocketBuilder applications can be run on the mobile device in two ways:
Using the ‘stub’ application that is installed into the Pocket PC start menu as Pocket PowerBuilder 1.0
2) By clicking directly on the application .exe (which is put into the ..\windows directory by default)
Deployment Platforms
ARM based Pocket PC devices
This covers all devices coming out with Pocket PC 2002 operating systems
MIPS, SH3 chipsets are not supported as device manufacturers have all but stopped making these devices

43. Summary
Pocket PowerBuilder provides the features that are required to develop enterprise smart client applications
PowerBuilder users can use their existing skills and application code to develop Windows CE applications
Windows CE applications are similar, but yet quite different than desktop applications, so design your applications accordingly
There are many related technologies available for developers to increase the sophistication of their applications, and their productivity at the same time

44. Summary Tips Always think ahead
Don't forget about your current development practices
Use the devices and the networks to learn them
Don't forget about security
Figure out what part(s) of your application make sense for the device
A good UI is very, very important
Use a local data store
Think ahead – data size (devices less upgradable than a laptop), platforms (when developing, keep porting in mind), …
Dev practices – treat mobile like desktop
Use devices, networks – wireless LAN hardware is cheap – < $200 for AP and card
Security – minimize risk, not eliminate it
Good UI – small device, can’t afford to waste space
