Mikhail,
So I ran into a snag using your method, maybe you can help me a little
more. I'm able to cast the abstract pointer to my object, but it isn't
a valid pointer to the object. Is there some trick to setting the
"abstract" pointer to my object? I'm really confused.
SSHConnection* this_ = static_cast<SSHConnection *>(*abstract);
password = this_->getPassword();
But at this point, running my getPassword() function dies because it
tries to return the value of a SSHConnection member variable that
doesn;t exist because the this_ pointer is not valid.
Any ideas?
Paul
