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?
