Major features in PowerBuilder 10







Plug-In technology and PowerDesigner
EAServer components as WebServices
UDDI support in PowerBuilder
XML-Web DataWindow
DataWindow .NET
Unicode support
Other changes
Plug-In Technology
Plug-In Technology
The good news!!





Plug-In technology will be open for everyone
PB community can write own Plug-Ins
PBGenericPlugin100.dll
appears to be COM component
Plugins stored in registry

HKLM\Software\Sybase\PowerBuilder\10.0\PBPlugins
Plug-In Technology
The bad news!!
Specification not before PowerBuilder 11 for
the public
PowerDesigner Plug-In


Many Applications in use today have not undergone formal
design
Many applications have a less than desirable architecture





This makes the application difficult to maintain
This makes the application difficult to enhance
Few client/server applications can easily be partitioned for ntier or web deployment
It has been a market trend of late to integrate
programming and modeling tools
With PowerBuilder 10, application designers and
developers now have a productive design and
development integration tool
Web Services Enhancements
Web Services Enhancements

The PowerBuilder developer no longer needs to utilize the
Web Services Toolkit within Jaguar Manager or Eclipse

PowerBuilder 10 will allow developers to deploy their
components (NVOs) directly to EAServer 5.0 as
(Axis) Web Services
Web Services Enhancements - UDDI

UDDI - Universal Description, Discovery and Integration
(UDDI) Service is an industry-wide effort to bring a common
standard for business-to-business (B2B) integration

It defines a set of standard interfaces for accessing a
database/directory of web services

As a pioneer of web service implementations, we provide this
web interface to the live registries
Web Services Enhancements - UDDI

Simply put, if a user wants to search for a web service on the
Internet, they can use the new UDDI browser to find it
Web Services Enhancements - UDDI
Web Services Enhancements - UDDI

PowerBuilder 10 provides wizards to guide developers for
UDDI browsing and consuming searched Web Services in
both PowerBuilder applications and JSP clients

PB developers may also use this UDDI searching capability
and build it into their PB applications since this UDDI feature
would be delivered as a PBNI extension
Web Services Enhancements - UDDI
DataWindow.NET
DataWindow.NET

DataWindow.NET

Provide DataWindow.NET Classes in C#

Use DataWindow for building your .NET applications

Use DataWindow controls in your Windows Form
now, and Web Forms soon
Unicode
Unicode enabling

PB 10 will be fully Unicode enabled
 Multiple languages within same DataWindow

Developers may input, retrieve and display multiple languages
in Unicode



Within the same window
Within the same DataWindow.
Develop your application in single set of codes and deploy to different language
environments
Unicode enabling

Unicode enabling - Definitions
DBCS - double-byte character set
– Uses 1 byte to represent a character such as ASCII
and European languages.
– Use double bytes to represent a character such as
Chinese, Japanese.
– Different languages have different character sets/code
pages!!!
DBCS PBL
– The PBL developed in PowerBuilder 9/8/7.
– The encoding for source code in PBL is in DBCS.
Unicode enabling

Unicode enabling - Definitions
Unicode
– Unicode provides a unique number for every character,
no matter what the platforms/languages are.
– It uses a single coded character set that maps each
character in the abstract repertoire to a 21-bit value.
Unicode PBL
– The PBL developed in PB10 and above.
– The encoding for source code is in Unicode
Unicode enabling

String-Related Functions


In PowerScript, some string manipulation functions have been modified to
handle Unicode data.
Affected functions:
– Calculating the length of a string
– Manipulating a string based its length or the absolute position within
a string
– Deriving sub-strings.
– WinAPI
Exporting/Importing


When you export an object to a .sr* file, you can choose to export it in ANSI,
HEXASCII, UTF-8, or UTF-16LE formats.
When you import a file with any format, PowerBuilder converts it to Unicode.
Unicode enabling

New Functions




The AscW function converts the first character of a string to its Unicode code
point. A code point is the numerical integer value given to a Unicode character.
The CharW function extracts the first Unicode character from a string or
converts an integer to a char.
The FileLenth64 and FileSeek64 provide support for larger files and return a
longlong value and can be used with files of any size.
Overloaded functions


String (blob, encoding)
Blob (string, encoding)
Unicode enabling
PowerBuilder 10 helps you during migration!

Convert DBCS String-Manipulation Functions check box on
the Migrate Application dialog box, Asc is converted to AscW
and Char to CharW.

Converts API calls using String parameters

Private Function Long mciExecute (String lpstrCommand) Library "winmm.dll"
alias for "mciExecute;Ansi"
XHTML Web DataWindow
XHTML Web DataWindow

The HTML Web DataWindow so far
XHTML Web DataWindow
HTMLGenerator 90
 DataWindow generated entirely in static HTML page
 Regeneration required on every roundtrip to server


Server processing/scalability unnecessarily strained
Bandwidth misspent on unnecessary downloads

Generator is string-buffer-based, limiting extensibility
Customization of generated HTML or CSS not supported

ALL of the presentation markup is generated too often

XHTML Web DataWindow
“When do I use the XHTML Web DataWindow?”

Since the XHTML Web DW can cache the presentation and
stylesheet on the client…

…the XHTML Web DW works especially well for graphically
rich DataWindows which are meant for the user to ‘scroll’
through multiple pages of data
XHTML Web DataWindow

XHTML Web DataWindow now
XHTML Web DataWindow

The XHTML Web DataWindow builds upon the
existing HTML Web DataWindow plus:



XML-based architecture
Updated web technologies
Improved performance using less bandwidth

Using XHTML as the ultimate/final markup also affords the
ability to customize that markup logically within the
PowerBuilder IDE.

Standardizes on the latest client-side XML technologies of the
version 6 browsers.
XHTML Web DataWindow

The XML Web DataWindow is essentially designed to
separate the content, the layout, and the style of the
DataWindow on the Web

Since the XSLT (the layout) and the CSS (the stylesheet) may
be cached on the client, only the relatively small XML content
(dynamic/displayed data) consumes bandwidth on
subsequent downloads as the user ‘browses’ the data
XHTML Web DataWindow
XML
Content
XSLT
Determines
structural
layout
Determines style of
elements as displayed
in browser
XHTML
The DataWindow engine generates each of these
components at runtime.

Other features
Other New Features in PowerBuilder 10
ADO.NET
 The System.Data.OleDb namespace is the .NET Framework
Data Provider for OLE DB.
Future:
Build full .NET applications in PB IDE
Consume .NET objects in PB applications
Convert existing PB apps to Web apps
With 1 set of codes, optionally build Windows or Web applications

Other New Features in PowerBuilder 10

Exception handling support in machine code

Additional parameter for SaveAsAscii

Boolean RetainNewLineChar. whether line feed and carriage return characters
contained within the row are converted to white space. false (default) - line
feed and carriage return characters within the row are converted to white
space
Other New Features in PowerBuilder 10

Environment variables for



memory management
exceptions in EAServer for PB components
508 Accessibility

Section 508 of the Rehabilitation Act of 1973 requires that when Federal
departments or agencies develop, procure, maintain, or use electronic and
information technology, they shall ensure that the technology is accessible to
people with disabilities.
§1194.21 specifies the requirements for software
applications and operating systems.
