I'm currently working on converting a simulator program from Visual
Basic 6.0 to Visual C++ .NET. I've figured out most of the stuff, but
there's still one thing I haven't gotten to and I've never really had
to deal with it before. I'm programming a front-end for what is a
compiled Fortran program. The VB source does the following to call
the Fortran:
'Defines the subroutine.
Declare Sub Cycle_DW Lib "cycdw.dll" Alias "CYCDW" (ByRef ncall As
Long, ByRef tcr As Double, ByRef II As Long, ByRef XX As Double, ByRef
xres As Double, ByVal AA As String, ByVal aaSize As Integer, ByVal
ares As String, ByVal aresSize As Integer, ByVal ltable As String,
ByVal ltableSize As Integer)
'Actually calls the subroutine.
Call Cycle_DW(lCycMode(1), dCritTemp(1), II(1), XX(1), xres(1), AA,
480, ares, 4800, ltable, 37 * 80)
The program is using 1-indexed arrays (hopefully it'll convert over to
using 0-indexed arrays in C++ with no problems), and it's passing a
pointer to the first element of each array. The numbers 480 and 4800
are character lengths; two arrays are being passed to the program
which are huge arrays of characters, with each 80 characters
representing one string (kind of an awkward way to do it, I know, but
that's how the Fortran program does it and I can't change that).
So, how would I go about converting this to C++? Thanks in advance.
