Independent IT consulting organization Focusing on OpenEdge and.net Located in Cologne, Germany Customers in Germany, Europe, USA Vendor of tools and consulting programs 20 years of Progress experience (V5 V10) GUI for.net early adaptor (since 10/2006) Consultingwerk Ltd. 1

2 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion 3 OpenEdge GUI for.net A Microsoft.NET based Windows graphical user interface that can replace or be integrated into an existing OpenEdge GUI application Consultingwerk Ltd. 2

3 OpenEdge GUI for.net State-of-the-art UI on the Windows desktop Integrated feature of OpenEdge 10.2A and 10.2B Supported by both GUI clients Fat client, prowin32.exe WebClient No separate license required Deployment Development Access and use any.net control 5 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion Consultingwerk Ltd. 3

4 Adoption Challenges Need to support pre-10.2a users as well Thousands of existing screens Training requirements OO fundamentals (new programming paradigm).net fundamentals Infragistics controls (or any other vendor) OpenEdge 10.0: ProDatasets etc. New tool: OpenEdge Architect 7 Adoption Challenges What are our architecture requirements? Where s the ADM3? Or at least a working complete sample application? I ve never used Office 2007, but my customers or sales people request the ribbon Dockable panes, Explorer bars? What are you talking about? Where the heck is the Orb in Office 2010? Consultingwerk Ltd. 4

5 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion 9 Parallel Use of ABL GUI and GUI for.net Progress client supports ABL widgets and.net controls at the same time Procedures may instantiate and interact with classes Classes may run procedures Procedures may create.net controls and subscribe to events Consultingwerk Ltd. 5

6 Enable ABL UI menu.w to support.net Forms Requires: The (one and only) WAIT-FOR Statements needs to be.net style Small modification in mainmenu.w program WAIT-FOR CLOSE OF THIS-PROCEDURE. /*.NET WAIT-FOR not associated to a.net Form */ WAIT-FOR System.Windows.Forms.Application:Run (). /* Use this method to terminate the WAIT-FOR, e.g from a WINDOW-CLOSE trigger. */ System.Windows.Forms.Application:Exit(). 11 Enable ABL UI menu.w to Support.NET Forms Requires: The (one and only) WAIT-FOR Statements needs to be.net style Small modification in mainmenu.w program Replace WAIT-FOR CLOSE OF THIS-PROCEDURE. WAIT-FOR for.net support /*.NET WAIT-FOR not associated to a.net Form */ WAIT-FOR System.Windows.Forms.Application:Run (). /* Use this method to terminate the WAIT-FOR, e.g from a WINDOW-CLOSE trigger. */ System.Windows.Forms.Application:Exit() Consultingwerk Ltd. 6

10 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion 19 Integration of ABL GUI into.net Forms ABL Windows embedded into.net Forms Core feature of OpenEdge 10.2A and 10.2B, contents of Window will be embedded into a.net control Original intention was mixed mode MDI Upgrading the appearance of ABL application by using.net controls (menu, toolbar, Explorer bars, dockable panes, lookups with UltraGrid, ) Step-by-step introduction of additional (Infragistics) controls to increase users productivity Active X controls contained on the window are well supported (documented in K-Base) Consultingwerk Ltd. 10

17 Embedded ABL Windows Menu Bar Window Border Client Area (FRAMEs) Message Area Status Area 33 Embedded ABL Windows Client Area (FRAMEs) Consultingwerk Ltd. 17

18 Embedded ABL Windows.NET Form Client Area (FRAMEs) Window Container 35 Embedded ABL Windows ASSIGN ocontainer = NEW WindowContainer () ocontainer:embeddedwindow = hwindow. Window may not yet be REALIZED (i.e., HIDDEN and VISIBLE not yet set, no LOAD-ICON) When using AppBuilder generated code, this is only possible by using the Method-Library and include files Consultingwerk Ltd. 18

19 Recommended Practices Use include files for modifications on existing.w files; use compile-time check for pre 10.2A support Render.NET controls dynamically from existing ABL widgets (menu, toolbar first) Identification of additional ABL widgets that may be substituted with.net controls (low-hanging-fruits first, tab folder, browser, ) Design specialized.net controls using Visual Designer, no dynamic code without need 37 Recommended Practices / Event Handling Keep the control in the.w file to reuse existing logic.net Event handlers should APPLY ABL Events CLOSE OF WINDOW FormClosing Event should always be cancelled as ABL WINDOW-CLOSE trigger might terminate with RETURN NO-APPLY CHOOSE of MENU-ITEM, BUTTON,.NET ToolClick Event Handler executes ABL Event (i.e., CHOOSE on ABL widget) Consultingwerk Ltd. 19

25 Shuttleworth: Data Window ABL Frame 49 Customer Feedback on Embedded Windows Takes away time pressure from Progress ISV Recognizable UI improvements with minimal effort Reduced implementation risk (reduces testing and training) Same source code remains usable on V9, V10.0, V10.1 (preprocessor checks) Simplified maintenance, single code base Developers can still use the well-known tools (AppBuilder) to maintain the application Technology change at the pace of the team, not the trend No shock for existing users, but sales easier Consultingwerk Ltd. 25

26 Enhancing ABL GUI s Appearance Don t underestimate the power of new icons or images (before showing the first prototype to users or decision makers) It s usually worth US$ 250 for s of icons (even when you may have to change later) Review colors and fonts of the ABL GUI, use the blue colors known from Office 2007/2010, use modern fonts (Segoe UI, Verdana) 51 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion Consultingwerk Ltd. 26

27 New Development Using GUI for.net Possible strategies New screens integrated into existing application (e.g., scheduler/planning screen or drill down) Redevelop whole client New development might go along with an architectural revision (OERA) UI as the driver for new architecture 53 New Development Using GUI for.net Don t underestimate the time required to build (good) reusable components Requires at least basic OO understanding Type concepts, interface types, CAST Strong typing can be a blessing and a curse UI Framework or template building requires good OO design skills and knowledge about Visual Designer internals Extension of (some).net classes is key to productive application development Don t inherit just because you can Consultingwerk Ltd. 27

28 New Development Using GUI for.net Get used to MSDN, Infragistics Forum, Google and.net community sites (e.g. Codeproject) to find answers to how-to questions Learn translating C# or VB.NET to ABL Consider hiring a.net developer or mentor for the UI (but let him know that AppServer is not an SQL server or a Web server) 55 Agenda Review GUI for.net Adoption challenges Adoption strategies Parallel use of ABL GUI and GUI for.net Embedding of ABL GUI into GUI for.net (and vice versa) New development using GUI for.net Conclusion Consultingwerk Ltd. 28

29 Conclusion GUI for.net is well integrated in today s ABL and client products Fully compatible to classic ABL GUI Nobody forces you to rewrite your client (at once) Start with integrating existing app into GUI for.net Consider new architecture (OERA) Tools available to support adoption of GUI for.net Start using OpenEdge Architect and OO today! That is the best starting point for GUI for.net 57 Additional Information Please visit our booth at the Exchange Online 2010 solutions expo!
