Bad calling convention

[Intel_C_Intel]

Hello,

I have some F77 code for a dll that was compiled by somebody else. I have the dll and the source code (but not the original compiler). The dll works fine with an Excel application.

I created a new DLL project in IVF 9.0 and added all those files and built the dll. When called from Excel, the functions in the dll execute fine, but on exit I keep getting the error 'Bad DLL Calling Convention'.

I tried changing the calling convention under project project properties but didnt help. What should be the correct convention ?

Thank you.

You would want "Stdcall, reference" as the convention (or "CVF") for compatibility with Excel.

Right. I thought so too. But when I set it to STDCALL REFERENCE, but I still get the BAD DLL calling convention error.

Fortran Call :

subroutine SETUPdll(i,hfld,hfm,hrf,ierr,herr)

!DEC$ ATTRIBUTES DLLEXPORT::SETUPdll

!DEC$ATTRIBUTES ALIAS: 'SETUPdll'::SETUPdll implicit double precision (a-h,o-z) implicit integer (i-k,m,n)

c Previously the attribute was here

parameter (ncmax=20) character hfld*10000,hfm*255,hrf*3,herr*255,hfmix*255 character*255 hf(ncmax)

......

END

Excel Call :

Public Declare Sub SETUPdll Lib "REFPFF" (i As Long, ByVal hfld As String, ByVal hfmix As String, ByVal hrf As String, ierr As Long, ByVal herr As String, ln1 As Long, ln2 As Long, ln3 As Long, ln4 As Long)

thanks.

Hmm - make sure that the String Length Argument Passing is set to "after all arguments".

[Intel_C_Intel]

Thanks. Done that already. Still doesnt work.

I have the Code Generation option Generate Reentrant code set to yes. Does this have to do anything with the error ?

thanks

No. I suggest you send your project and Excel code to Intel Premier Support and we'll take a look. Ask that it be assigned to Steve Lionel.

Is there a site where I can download a sample project for fortran dll that is called from VB/Excel ?

thanks
