Bernie,
I think I follow the reasoning, but it is gonan take some time
to work out where on earth this is occurring. At least I now
have a handle on what it means, even if I have no idea quite
where to look for it!!!
Thanks
Andy:
Here is what that error means:
No object has been instantiated to handle the pure virtual function call.
This error is caused by calling a virtual function in an abstract base
class through a pointer which is created by a cast to the type of the
derived class, but is actually a pointer to the base class. This can
occur when casting from a void* to a pointer to a class when the void*
was created during the construction of the base class.
