[Dev-C++] compile error

[<jd...@da...>]

why when i try to compile a program with the #import directive I obtain this
error?
undefined or invalid # directive.
How can I import functions stored in a dll?
Im trying to use
this:
#import "c:\Programmi\File Comuni\System\ADO\msado15.dll" \
no_namespace rename("EOF", "EndOfFile").
Please forgive me for bad english, I'm Italian!
