If you go here and download the file mydll.zip:

http://www.sourcecode.nu/zone15/cat161/

or the file CDLL.ZIP: 
( This is a long url be sure to use it all because euform wraps it ) 
http://www.sourcecode.nu/search/advsearch.asp?ZoneID=-1&caller_page=&page=3&SearchMode=1&SearchTxt1=dll



You will find the files you need to build a DLL in "C".
MYDLL.ZIP shows the minimum needed to build a DLL.

CDLL.ZIP shows how to build a DLL and has a test program
showing how to call it.

Also if you do a search at this site on DLL you will find
lots of examples of call dll from other langaguges.
