Sentinel hardware key VI

[SeanJ]

Hi,

I am trying to use the sentinel hardware key by way of a labVIEW VI.  I have created the attached code.

The problem arises as the result returns all zero's or all 202's.  I spoke with a representative and they informed me that a zero is a good result and 202 is bad. 

It seeems to vary between these two results.

Does anyone know where I have gone wrong with my code?  Should I keep submitting the other non secret key parameters on each round?  Is the data formatted ok?

I've really hit a brick wall!

Thanks,

Sean

Can't really tell much about the formating without the DLL documentation.

Hi Jeff,

I tried attaching the dll previously but it's not allowed.

I've attached some headers here and  here's some more info:

Business Layer API - Quick Reference
❑SFNTSetContactServer - Sets the Sentinel Keys Server to be contacted for obtaining a license.
❑SFNTGetLicense - Obtains a license from the Sentinel Key having required developer ID and license ID.

C API function syntax

unsigned long int   status;
unsigned long int   DeveloperID;
unsigned long int   licID;
unsigned long int   flags;

status = SFNTGetLicense( DeveloperID,
                         SOFTWARE_KEY,
                         licID,
                         flags,
                         &licHandle );

if (status != SP_SUCCESS)   {
  // If a key with the requested developer ID and License ID
  // is not found or a valid license is not available,
  // then SFNTGetLicense will return an error.
}

Sine the VI is in LabVIEW 2009 I can't look at it (yet).
