Using a C++ class in VB is nearly impossible (it is possible, but very hard and likely to attract bugs), except when you use .NET (and that's not a C++ class anymore).
You'd have to look up the mangled name, specify it as the alias of the function name you really want to use, then create a Type in VB that exactly matches the data structure of the class, initialize it correctly and pass it ByRef as the first parameter to the function (that's the this pointer).
