After designating which PBLs you want to have the tool examine, you'll be able to print, save, and browse the Migration Assistant's analysis report. (Figure B)
You can now begin formalizing your Migration Plan.
The Migration Assistant is a great boon to the developer in that its
discovery success rate is close to 100%, but you'll want to add a
thorough quality assurance cycle to the tail end of that plan.
Once you believe you and your team are ready for the migration process, open the application in PowerBuilder 11. The Migrate Application response window will open. Verify your library list, choose your message notification level, select whether you want PowerBuilder to automatically convert DBCS string manipulation functions appropriately for unicode usage...this is the point of no return and your last chance to back up your PBLs...then click OK. (Figure 3)
Unsupported Features in Windows Forms Projects
In its 11.x time frame, PowerBuilder is a .NET deployment solution. That is, the developer isn't strictly working with .NET in the PowerBuilder IDE. (.NET in the PowerBuilder IDE is slated for version 12). As such, any application can use PowerBuilder features that are appropriate to Win32 deployments, but aren't supported yet or not appropriate for .NET deployments. (Figure C)
There are, however, those unsupported features that Sybase doesn't plan to support for .NET deployment such as non-visual classes for profiling and tracing. PowerBuilder developers will have to identify where in their applications they may be using unsupported features and then decide how they want to refactor the application to work around each feature. The next part of this article will cover identifying unsupported features in your application, yet I highly recommend at some point that you review Chapter 11 of "Deploying Applications and Components to .NET" in the documentation to become familiar with this reference for "Unsupported Features in Windows Forms Projects".
Deploying Your WinForm Application
OK. It's time to deal with the nuts and bolts of features not supported for WinForm-deployed applications, so it's time to do our initial deploy! Since the thrust of this article is preparing your PowerBuilder application for WinForm deployment rather than the details of how to actually deploy it as WinForm, I'll refer you to the detailed external resources on just how to do that.
In the core document "Deploying Applications and Components to .NET," Chapter 9 "Deploying PowerBuilder Applications as .NET Windows Forms" takes you through the use of the .NET Windows Forms Application wizard.
There are also detailed recordings of deploying/publishing your WinForm application using .NET Smart Client techniques. Look for demonstrations of PowerBuilder 11's "Intelligent Updater" at www.sybase.com/products/development/powerbuilder/videos and at www.sybase.com/products/development/powerbuilder/webcasts.
The .NET Deployment Output Log
Once you've deployed your target as a WinForm, you'll want to examine the tabbed output logs in the PowerBuilder IDE. Exporting can save these logs and I highly recommend you do so.
Pay attention to the Default, Warnings, and Errors logs first. They arguably will have the most critical issues needing your attention. A text file named DeployLog.txt is generated with each .NET deployment in PowerBuilder 11. Besides aiding you with deployment errors it may be beneficial in helping you resolve any remaining configuration issues.
Now it's time to examine the Unsupported Features output log.
The Unsupported Features output log is populated the first time you deploy to WinForm and each subsequent time you choose to do a full rebuild. Of course, if after a deployment you add any features to your application that are unsupported, even an incremental rebuild should yield a populated output log. There's a lot of useful information in that output log, but I'm sure you'll agree that it'll take some effort to read through it in its raw form and continue to use it as a reference document as you formulate your Refactoring Plan. That's why the .NET Features Analyzer was recently introduced.
The .NET Features Analyzer IDE Add-in
The .NET Features Analyzer is available on Sybase's codeXchange Web site at https://powerbuilder.codexchange.sybase.com....
This tool was created in the 4GL tradition to provide you with a productive IDE for browsing the Unsupported Features output log.
The tool is an add-in to the PowerBuilder IDE. Once installed, open it from the File>New menu item in the IDE and select it from the Tool tabpage of the New response window. Use the tool to open a saved output log or tell it to import the log that may be open in the PowerBuilder IDE. .NET Features Analyzer lets you browse unsupported features by class and PBL. In its IDE, you may also examine the raw output log as well as any exceptions that are thrown. All of this may be printed and you may save the raw output from here as well. (Figure 4)
Formulate Your Refactoring Plan
So once you've identified the features in your application that aren't supported in a WinForm deployment, it's time to divide and conquer. Decide what workaround you'll use for each unsupported feature, how much time it'll take, what resources to assign, and estimate a time frame. In other words, you won't want to skimp in managing this as a formal project.
A couple of caveats while you refactor your PowerBuilder application for WinForm deployment: 1) the functionality of the debugger for .NET deployment targets is different from Win32 deployments using pcode; 2) You may want to consider migrating to PowerBuilder 11.1 rather than version 11 to take advantage of the incremental compilation that was added. Otherwise your entire application will have to be compiled before you can see the runtime impact of the modification of a single line of code or even a minimal layout change in one of the visual painters. While the runtime speed is comparable to Win32 deployments, full build-and-deploy times for a library list of PBLs amounting to 150MB can take as much as a half-hour.
Additional resources are available to aid you in this process. Besides the white papers and tech tips available from the support section of the Sybase Web site, there are technical articles in the PowerBuilder Developer Journal, the ISUG Journal, as well as the International Developer Magazine. The most notable supplemental resources in my opinion are the PowerBuilder newsgroups.
The Sybase newsgroups are where your peers and a group of skilled volunteers (TeamSybase and Team iAnywhere) answer questions posted on a range of Sybase products and solutions. I can't think of a better place to get an answer to a question by a person who discovered the solution to the problem you're experiencing today...six months ago.
The Most Productive .NET Developer
PowerBuilder isn't the first development tool to take you to .NET, but it's among the first. Sybase wanted to ensure that PowerBuilder users could take their applications and their components to .NET long before they had to. PowerBuilder ensures that you don't have to rewrite all of your applications completely from the ground up to take them to .NET...unlike some of its competitors have.
PowerBuilder 11's WinForm deployment capabilities take the PowerBuilder presentation layer application of your two-tier or n-tier solution to .NET today and preserves your standing as the most productive business application developer on the block.
