Re: [TRNSYS-users] New Module with External File

[Ken HATAKEYAMA <ken@imagicdesign.co.jp>]

David and Yoshihiro,

Thank you for your response.
I tried to use the function getLUFileName, but finished in failure.

Because the function, getLUFileName is not implemented in TRNDLL.dll, I have to
rebuild TRNDLL.dll.

I added to "TRNSYS.h" the following 2 lines;
extern "C" __declspec(dllimport) char* _cdecl TRNSYSFUNCTIONS_mp_GETLUFILENAME(int LU);
#define getLUFileName TRNSYSFUNCTIONS_mp_GETLUFILENAME

And I added the code that David wrote to "TrnsysFunctions.f90".
Finally, I builded TRNDLL.dll using CVF 6.6B and I suceeded building TRNDLL.dll
and the TYPE using the function.

But when I tried to run the project, an access vioration occured in DFORRT.dll
and the TRNSYS project was terminated.

Best regards,
Ken Hatakeyama
