Hi there, we are still using the old Crystal Reports 8.5 apis to elaborate reports from our pb application. Since latest cr versions have discontinued COM, is there any workaround out there to make it work from powerbuilder?

Hello Simone,

recent versions of CR do not expose anymore a COM interface, only .NET or Java SDKs.

That means PB applications cannot use anymore OLE to manipulate and display CR reports.

What you can do is to take the CR .NET SDK and call the new interfaces (visual and non-visual) by using MS Interop and expose them to COM.

Here the HowTos from Bruce:

Best,

Hi Simone,

 

I faced the same problem you did, so 've made a Crystal Report Viewer control in C#. The code is a mess, since my first goal was to implement all of the powerbuilder OLE code into .Net without changing any of the existing twisted code, but it works.

You'd have to download Crystal Reports for Visual Studio 2013. I haven't tested yet the latest patches, since there was a problem with exporting Calibri fonts to Excel / PDF. Patch 18 fixed that problem and later patches broke it again. (I still have to checkout the latest CR path which I think is 23).

Though I cannot just send you a working ActiveX I can try to clean out as much code as possible and see if that helps. As Marco said, you have to wrap your functions in an ActiveX and export the functions you need.

You can than paste the activeX in a window and use OLE to call the functions.
