PowerBuilder 12.1, b7055
PowerBuilder 2019R3, b2703

Summary
I need a way to pass PowerBuilder data from one PB app to another, separate PB app.

Details
I discovered that our invoice production process was literally 5 times slower in PB2019R3 than in PB12.1. This is a show stopper, but I may have found a way to move forward.

I want to extract the invoice production process from the application and create a new and separate PBv12.1 application that does nothing but take data from the main app, do the processing, and return to the PB2019R3 main app.

To facilitate that, I need a BUNCH of data from the main app. How do we pass bunches of data around? With a structure, of course! I just started and this is what I need so far:


Sadly, the only link between the main app and the new exe is "commandline".

I can use FindWindowW (main_app)  and get a handle to the main app, , but I don't know how to access internal data - strings, longs, DWs, and so on. I'm not sure if that's even possible.

For a DW I san SAVEAS an Excel file then import it into a copy of the dw in the new app, and I can do that for all of the required data in a similar manner, but....blech. I'[d rather be able to use dot notationi and reference the main_app internals.

Can this be done? If so, how?


Thank You!
