Hi Arnd;
That is a great suggestion!
Personally, I have not had the chance to address the 64bit world in my STD Frameworks because I still only develop them using PB 12.1. That PB version is my lowest common denominator in the PB Community at the moment ... mainly due to the current low adoption rate of PB V12.6 (many various reasons for that one).
However, with Appeon coming on "main stream" with PB Development very soon and the new planned Appeon PB Classic being based on the v12.6 code line, I am now considering moving my frameworks to PB v12.6 (with all EBF's applied) in the near future. I hope to not only address new features like Dockable Windows in the Integrated framework but also the 64 bit compile realm as well.
Unfortunately for Tom, he is a bit on the bleeding edge on this one. However, I hope he tries your suggestion and reports back here as to its applicability.
Thanks again.
Regards ... Chris
