Connector 8.0.12 PreparedStatement

[Ivo Grzanowski]

Hello together,
I have two issues:

1) I try to compile an application using Connector C++ 8.0.12.
The compiler misses the definition of the class "PreparedStatement". It is declared but not defined. Where do I find the definition?

2) I wonder why the class "Statement" is working. (It's definition contains many virtual members.) But when I try to run the app - it crashes with a heap error.

I think all the required Lib's/DLL's/headers are linked/included.

My machine:
Win 7/64
Visual Studio 14 (2015)
