Extraneous formal parameter specification for calling lib function

[a710756]

hi, everyone

I want to call the library function in CVI. When i run the project,  it shows some "Extraneous formal parameter specification" errors message.(as below picture)

I have no ideal with this errors, because i call the library function in VC6, it's OK with no problem.

Could someone help me to solve this problem?

Thank you! 

my CVI file: http://d.99081.com/a710756/Test3.rar

the CVI errors:

Hi,

What about:

__declspec(dllexport) void Func(void);

CVI expects two underscores before declspec (i.e. __declspec, not _declspec). VC allows either _declspec or __declspec. You can either do a search/replace, or add a define like this one to your file:

#define _declspec __declspec
