I just stumbled across this thread and wanted to remind everyone about
the TERRIFIC free DLM that Randall Frank has on Ronn Kling's website.
Here's a snipit about the relevant section:

------------------------------------------------------------ ------
* A generic interface for calling Windows DLL functions directly

This interface allows an IDL program to directly access the
exported functions in any Windows DLL. This interface can
replace the CALL_EXTERNAL wrappers for many functions under
Windows. The interface consists of two functions. One to
define the external function to IDL and one to query the
external function table.
------------------------------------------------------------ ------

I have used this interface with 3rd party DLLs (i.e. no source code)
with great success (National Instrument's VISA library). I consider
this DLM an essential part of my IDL code (gush gush). Check it out.
