Origin Version (Select Help-->About Origin): 7.5
Operating System: Winxp
Trying to fit a quite complex user-defined external dll function. The template provided in File Exchange supports .c grammar only. Is there any template showing how to code external dll by .cpp in visual c 6.0? thanks.

Seems that Ocolleagues are busy so I did it by myself. Here is the procedure to share with those who have the same request.
Definition of the problem:
If you want to sovle a complicated fitting problem, which involes
1) calculation of complex numbers (#include <complex>);
2) calling memeber functions of an existing C++ class;
3) you are an OOP lover.
Solution of the problem:
General an external DLL for the fitting function based on
http://www.originlab.com/FileExchange/details.aspx?fid=105
Modifications required:
1) rename FitFuncs.c to FitFuncs.cpp
2) replace FAR PASCAL by __stdcall
3) delcare LPDOUBLE and LPSHORT in this way instead:
typedef double* LPDOUBLE;
typedef short* LPSHORT;
that's all.
