Hi,

 

In my company, we have C++ code that loads PBVM19.DLL in order to access PB code. Everything worked fine while we were running version 19. Once we moved to 2022 R2 we are having issues loading PBVM.DLL, Our C++ code is unable to load the DLL. We've tried lots of things but nothing worked.

We also tried to follow the example on the documentation (https://docs.appeon.com/pb2022/native_interface_programmers_guide_and_reference/XREF_79734_Calling.html#XREF_67012_Creating_the_C) but, once again, it doesn't work.

 

Any help will be appreciated.

Thanks.

Problem solved. The issue was related to to the location of PBVM and its references. Using a path helps find PBVM file but not its dependencies. 

We solved the problem by setting the right directory when using PB and then restore it to its original one.

Thanks a lot for your help.

Hi.

Powerbuilder 2022 R3 is built using a newer version of C++. Maybe the problem you encounter is related to that change.

If you are building a x64 exe make sure that the PowerBuilder x64 runtime can be found.
