Hi,

I struggled with this problem too. The problem is probably to be solved by
changing the build parameters of your dll.
I use IDL on window2000 and Visual Studio 6.0. I use an exports.def file to
export the dll symbols (rather than declspec-things)
see example below - hope this helps

Gert

exports.def:
--------------------
LIBRARY LocMinDll
DESCRIPTION 'ILD dll LocMin (c)GVDW'

EXPORTS
GetVersion
LocMinDll

------------------------

the code goes in a cpp file
--------------
IDL_LONG IDL_STDCALL LocMinDll( int argc, void* argv[])
{
<your super code here>
}
