Hi, i'm trying to connect a dll file to Mathematica 5.2. I was able to
get the examples (found in HELP) to work, so there shouln't be
anything wrong with .Net version.
exapmle:
In[5]:=
novaFce=DefineDLLFunction["GetWeight","C:\HGS
\libDynModelTrim.dll","double",{}]
Out[5]=
Function[Null,If[NETLink`DLL`Private`checkArgCount[GetWeight,{##1},0],
Wolfram`NETLink`DynamicDLLNamespace`DLLWrapper2`GetWeight[##1],
$Failed],{HoldAll}]
after
In[6]:=
novaFce[]
i got this error message
>From In[6]:=
NET::netexcptn: A .NET exception occurred:
System.EntryPointNotFoundException: Unable to find an entry point
named
'GetWeight' in DLL 'C:\HGS\libDynModelTrim.dll'.
at Wolfram.NETLink.DynamicDLLNamespace.DLLWrapper2.GetWeight().
Out[6]=
$Failed
function GetWeight() is declared as:
DYNMODELTRIM_DLLMAPPING double GetWeight();
where DYNMODELTRIM_DLLMAPPING is defined:
> if defined(LIBDYNMODELTRIM_EXPORTS)
> # define DYNMODELTRIM_DLLMAPPING __declspec(dllexport)
> # else
> # define DYNMODELTRIM_DLLMAPPING __declspec(dllimport)
> # endif
could DYNMODELTRIM_DLLMAPPING be source if this problem?
