Hi Jeff;

  Well I am totally confused. To me PFD means Personal Flotation Device (LOL) but, I assume that as a file type it could be related to a PlayStation file, Planning Force, Proform, iGrafx, etc software. All to which I have no idea what that could be used for in a PB App (or the PFC for that matter).

  Can you give us more details / context?

Regards ... Chris

Hi Chris,

I updated my post.  Looking for a PFC Extender that I can use to extend PFC 2017 libraries to PFD.  We have 2 applications where PFC libraries have PFD layer in its workspace.  So instead of the normal PFC and PFE libraries, there is another one which is PFD.  PFE libraries were inherited from PFD libraries.

Regards,

Jeff

Since the PFD*.PBL files already exist in the version of PowerBuilder you are currently using, what exactly is the problem?

As long as the app compiles, yo uare golden. Your inheritance chain is intact, so:

     application PBLs   <--  PFE PBLs  <--  PFD PBLs  <--  PFC PBLs

When we created a CORP layer, we had to manually add the new layer into the code.

I am not aware of a took that will do this for you, but it should be easy enough to write a quick app that looks at the EXPORTED files from your PFE and to overwrite the inheritance from PFC to PFD.

1. Export the contents of the PFE PBLs.

2. Run the app to change the inheritance from PFC to PFD

3. If the PFD PBLs are already inderiting from the PFC, you are good to go.
    If not, then tweak the app you just wrote to update the exported files of the PFD.

4. Import the exported files into a new, separate, not to screw up the original code set of libraries

5. compile.

The main issue I see is with obsolete objects.

Good Luck,

Olan

You have a lot going on here.  Just a few questions and some suggestions/options for you at the end.  How many objects actually have code in the PFD layer?  Is it feasible to go through the PFD and see what kind of functionality is in there?  You may be able to put that functionality into the PFE layer instead and eliminate the PFD completely.  Is there additional extensions in the PFE?  If there's no code in the PFE, you can always just move the PFD code to the PFE and then eliminate the PFD.

Here's something else that might work:

1) Backup EVERYTHING!

2) Setup 2 targets - 1 existing app, 1 with new PFC/E (easier to copy objects)

3) In your app target, use the NEW PFC PBLs with your existing PFD and PFE

4) Do a full build and fix errors for new objects / obsolete

5) Add any PFE objects that are new in PFC

Lmk how it goes or if you need additional advice.

Earlier versions of PowerBuilder (6.5, I believe, and maybe others) included a PFC "extender" tool which automatically created a layer between the pfc_ and pfe_ layers.
