Great, I already had the feeling my brain dead-locked when thinking about a
solution. :)

Okay, you mean in the header file where I derive a class from TBase. There I'll
write something like:

class MyClass : public TBase<MyClass>
{
// My class goes here, espacially overiding pvMethod()...
};

void TBase<MyClass>::pvMethod()
{
// Not so generic dummy function
// Copy and paste error handling here ;)
}

Not exactly what I wanted...

Or did you mean that the function definition is in the TBase header file? If
so: It is.

Thanks for your kind help!

Regards,
Björn!
