to_python with c++ class??

Hi,
just tried to figure out this by myself and by reading the docs and 
archives, but I failed:-(

Here is my problem.

I have an app which should 
a) export objects to python and
b) embedds python.

I managed to build a extension module using boost, which builds 
wrapper classes for my c++ objects.

In my App I include the extension dll to register my apps c++ objects
 
In the embedded python I load this extension module and get the 
objects using the wrapped registry.

This works really fine. I can get access the apps objects from python 
and change their attributes from there. 

What I don't know is how I can create an PyObject* from one of my 
classes to call a Python function with it? (embedded Python)

Code should like that:

#include "ext_mod.h"
int main(int, char**)
{
    Py_Initialize();
    CMyClass a;  // create one of my apps class objects

    PyObject *pMod = PyImport_ImportModule("ext_mod"); // load the 
extension module 

    // now I need a PyObject Pointer for my object a
    PyObject* pA = ?????(a);    

    // after that I would like to add it to the modules dict
    PyModule_AddObject(pMod,"a",pA);

    Py_Finalize();
} 
    
How do I accomplish this?

In the definition for my ext_mod module (boost) I use 
class_builder<CMyClass> myclass(mymod,"a"); 
to build an extension class. But how do I use this to call to_python
()?

How can I export this from my DLL if I have to use it to get my 
PyObject* from CMyClass?

Thanks a lot
