First let me recommend that you go straight to using DLM's and skip
call_external. You will be much happier with the results.

Now, you really meant idl32.lib not idl32.h, right? Assuming that is correct
did you include the call_examples.def file in the project? I avoid using
call_external so I don't know if you also need to have an export file, but
that might be a problem also.

If you want to get a really good book on calling C from IDL using DLM's go
to http:\\www.rkling.com and click the link to "Books on IDL" at the top of
the page;) Of course, I am biased on the book but I have received a ton of
positive comments on it!
