Hi Junghun,
This COM dll is a part of our legacy package from old versions of HASP. As there is no official support with LDK, we do not have any samples included in the package for VB6.
You can refer to the documentation from the folder to get the details on how to use the API's:
"C:\Program Files (x86)\Gemalto Sentinel\Sentinel LDK\Legacy\API\Runtime\COM"
Please contact us by creating a ticket on our support portal (https://supportportal.gemalto.com/csm/) if you need any assistance with the API's.
If you are not registered on the portal then please drop us an email to crmprod@gemalto.com mentioning your organization details to get your "Customer Identifier" needed for registration.
Regards,
Ashish
