Recently we upgraded to Powerbuilder 2019 R3 version from an older SAP-supported PB.   We have found an issue with the external call function which looks like is now cutting off the first 2 characters we get back from it. 

We make a call to a C++ Dll cal example -> function long fc_findfirst(string filespec,  REF str_finddata fileinfo) LIBRARY "PB2CShared.dll" alias for "fc_findfirst;Ansi"

When we get back the fileinfo it is cutting off the first 2 characters of the file name.  This is creating issues in our PB program. 

Using the same C++ DLL with the older PB works fine.  The structure of the code did not change on PB or the C++ side. The only change for this call was upgrading powerbuilder. 

 

I am not sure how to fix this issue? Does the new PB support a different way to compile the code to make this work or setting? 

 

the application is build with the pcode just like the older version of PB. it is a 32 bit application just like the older version of PB.
