Hello community,
here is an example code of a server application for an SAP system in AutoIt language.
My problem is, that this AutoIt example crashs after the first function call of ABAPCall from an ABAP report.
I try two methods:
Is there any other way to use this kind of multithreading?
Thanks for hints.
Cheers
Stefan

I try two methods:
- Use DllCallbackGetPtr
- Use CreateThread and get the address of the thread.
Is there any other way to use this kind of multithreading?
Thanks for hints.
