Dear Javier, I am trying to write trnsys16 components in C++. But, there are a few problem, as far as I see. In your case, I think C++ runtime library, which is linked with your DLL, is inconsistent with that of trnlib.dll. Try to do followings, - Recompile trnlib.dll with release mode. (The problem in debug mode is trnlib.dll is linking both msvcrt.dll and msvcrtd.dll. It is not good. I could not fix the conflict for now.) - In your DLL project, change the compile option like the attached png file. ( you don't care where it is release or debug mode ). It worked at least in my environment. Good luck.
