According to the WizSource documentation on Roland's site, you should be able to restore a prior version of any object to the IDE using the GET function.

If that doesn't work for you, I seem to recall someone offering this service, basically reverse engineering PBD's.  I believe the name was Jeremy Lakeman or something similar.  Pretty sure the first name was Jeremy.  Not sure if someone else here knows how to get in touch with him, or maybe try LinkedIN. 

Thanks Kevin,  The issue is that we never checked the files back in prior to running the automated PB Compiler (pbc170.exe), so when the compiler ran, it got latest from topWiz and overwrote a handful of windows that were already checked out with code changes.   

so was thinking the really option we had to get those changes was to see if there was a way to reverse engineer a couple PBDs to get the code changes.

Thanks
Jim

The only object you can reproduce source code from a PBD is the DataWindow.

There is a decompiler available that was written by someone in China. I actually have a copy of it. It doesn't work with PB 10 and higher.

Jeremy Lakeman has also done some work on a decompiler. I haven't emailed him in a year or two so I don't know what the status of it is.

To extract DataWindows, create an app adding the pbd files into the library list. On the window have a DataWindow that shows the result of the LibraryDirectory function.

In the rowfocuschanged event, assign the datawindow object to a datawindow control. In a button use the DataWindow.Syntax property to get the source code and write it to a file. Don't forget to add the object header as the first line.

Hi Jim;

   You can recover any object class definition and its source code from a PBD (but not a DLL) in various PB versions. However, this is not straight-forward. I would suggest contacting Mr Don Clayton at InterTech (one of Appeon's premier consulting partners). Don has had experience doing this for various PB customers.

You should create a workspace in another folder that is only for building your executable. That way it won't overwrite your checked-out work.
