PowerBuilder Native Interface (PBNI)
Since PowerBuilder IDE is 32-bit, this introduces some
challenges with PBNI interfacing with 64-bit. In the PowerBuilder IDE,
you can only import the 32-bit PowerBuilder extensions into the PBL
(using the Import PB Extension
context menu) or create the PBD file from the 32-bit PBX file using
the pbx2pbd220.exe tool. But for runtime, you can still package and
distribute the 64-bit extension libraries with your 64-bit
applications. What you need to do is compile the extension libraries
to 64-bit PBX files using the Visual Studio Wizards, and make sure
your 64-bit PBX files have the same name as the 32-bit files, since
the application references it by file name. (read
