Creating COM/COM+ component server in PowerBuilder classic 12 and above

We are in process of migrating our Power Builder classic code from PB11.5 to
PB12.6 ,

We have a PB Classic application which builds into COM/COM+ DLL's , being
exposed to and called by third party applications.

I see the functionality of creation of COM/COM+ DLL's is removed in PB12+ ,
This is hampering us from migrating from PB11.5 to PB12.6

Can anyone please suggest an alternative to this.

    Hi Amit

    You could possibly migrate them to PB .NET and deploy them as .NET components for the other applications to use. Not ideal but may get you out of the problem you currently have.

    Hi Amit;

    What your are talking about is the ability for PB to build an OLE Server COM object. Yes, that feature was removed by Sybase in the PB 12.x days I am sad to say and I have no idea why. πŸ˜”

    One suggestion I have for now is stay on PB 11.5. The PB product is being turned over from SAP to Appeon Corporation in the near future. I would suggest contacting them and adding this feature requirement or maybe something equivalent as an enhancement feature request.

    Another alternative (instead of .Net that David suggested) is to look at placing your OLE Server code into a Web Service and let your client applications interact with your PB code via WS Calls.

    PS: I feel your pain (PIA).

      Yes, we need to see what Appeon does with PB.Net. The product does not fit in Appeon's toolbox currently IMHO, and I have not seen any of Armeen's presentations mention moving forward with a WPF based IDE. Armeen has mentioned making PB Classic more .Net aware and also developing a new product based on existing PB & Appeon technologies that would be .Net based (at least that is my impression from the webinars thus far). If I have read the direction properly from the webinars, applications built in PB.Net be on a dead end (politically correct - "no exit") road. Hopefully, the next 1-2 webinars will make this PB development path much clearer.
