  1. PowerBuilder 10 Berndt Hamboeck

  2. Agenda • 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

  3. Plug-In Technology

  4. 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

  5. Plug-In Technology The bad news!! Specification not before PowerBuilder 11 for the public

  6. 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 n-tier or web deployment • It has been a market trend of late to integrate programming and modeling tools • With PowerBuilder 10, application designers anddevelopers now have a productive design anddevelopment integration tool

  7. Web Services Enhancements

  8. 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

  9. 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

  10. 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

  11. Web Services Enhancements - UDDI

  12. 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

  13. Web Services Enhancements - UDDI

  14. DataWindow.NET

  15. 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

  16. Unicode

  17. 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

  18. 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.

  19. 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

  20. 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.

  21. 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)

  22. 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"

  23. XHTML Web DataWindow

  24. XHTML Web DataWindow • The HTML Web DataWindow so far

  25. 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

  26. 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

  27. XHTML Web DataWindow • XHTML Web DataWindow now

  28. XHTML Web DataWindow • The XHTML Web DataWindow builds upon theexisting 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.

  29. 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

  30. XHTML Web DataWindow XML Content XSLT Determinesstructural layout Determines style of elements as displayed in browser XHTML CSS The DataWindow engine generates each of these components at runtime.

  32. Other features

  33. 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

  34. 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

  35. 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. •
