Answer question

Connection 800xA basic history server ( OPC HDA ) and visual studio ( C++ )

I am trying to make a program in visual studio (c++) that is able to read all the stored data in the basic history server.
( Some background: I am a student who doesn't have much experience with 800xA, OPC or databases )
I have read in the 800xA online documentation that 800xA does support OLE-DB, so I am planning to use that to connect to the basic history server.
I have also downloaded matrikon OPC HDA explorer, with which I could find an read all the data from the basic history server.
I couldn't get much info from the matrikon explorer. only the fact that the basic history server is readable and present.

I've tried to find documentation/manuals on connecting to the 800xA basic history server, but without any luck.

So my question's are:
Is it even possible to connect to the basic history server using standard c++ in visual studio ( or do I need support add-ons ( i found one paid support add on for visual studio that supports OPC HDA client features in c++ visual studio ))
And if so, is there maybe a document/example I can use for programming my program.
