I am using DLL's of GUI LIBRARY for C++ ( SAP AUTOMATION GUI INTERFACES ).
files
guilib.dll
guilib.lib
guilib.h
everything works correctly with the SAPGUI version 4.6D and previous , but with version 6.20 it has problems,
i tried to change to another transaccion or screen but it sends errors and it closes SAP,any action which I do in SAP closes the system.
Somebody know's if exists a new version from this libraries that support SAPGUI version 6.20
