Import vi from dll

Question

when i try to set up to import vi from .DLL  file, how do i include more than one .h file
(select shared lib & header file screen)
here's the warning message, and the import failed.
there's only 2 files which has the refer f(x)  -  *.dll & *.h
The shared library contains 1 function(s), among which the declarations of 0 function(s) are found in the header file and these function(s) will be imported. The remaining 1 function(s) listed below cannot be imported.
-  getAuthenticationArray ()
For each function, verify the following conditions:
1. The function is declared in the header file.   
2. The declaration of the function in the header file(s) is embraced by a valid predefined symbol.      
3. The predefined symbols are included in the list of valid predefined symbols. You can click the Back button to get to the previous page of the wizard and add the predefined symbol. 
4. The header file contains declarations for the functions to be converted.

Kitahara,
      To get a better idea of your issue please answer these questions:
1.What version of LabVIEW are you using?
2. What language was the .DLL created in?
3. Please attach any pertinent files
4. Have you looked at this resource?
Thanks,
