Hi Andreas,
Thanks for your quick response. From our current Powerbuilder 12.6 application, we are calling an oracle proc/package through which we are triggering the VC++ code to generate EDI files to be sent to other applications/customers. Currently the Visual studio version we have is MS Visual studio 2015. Since we are planning to migrate to Appeon PB 2019, I wanted to make sure that the interfaces will work as-is, though there is no direct connectivity between Powerbuilder and VC++ code. Please let me know if you need any further information. Thanks again.
