You need to compile this cpp class as a .DLL and then refer this dll in your VB propject.
You are good to go.

create a DLL.register
to to command prompt and type
c:>regsvr32 <complete path of DLL>
open your vb project. go to project-refrences- add the DLL from the list
now create a object
dim obj as new <nameof DLL.ClassName>
now u can use the function
hope this will work
