Dumps the contents of your object.When you write your own
class, you should override the Dump function to provide
diagnostic services for yourself and other users of your
class. The overridden Dump usually calls the Dump function
of its base class before printing data members unique to
the derived class.
Dump function should not print a newline character at the
end of its output.Dump is a const function, you are not
permitted to change the object state during the dump.
// example for CObject::Dump
void CAge::Dump( CDumpContext &dc ) const
{
CObject::Dump( dc );
dc << "Age = " << m_years;
}

* should dump information about its members that are not
inherited
* can set depth detail through SetDepth()
* by default, information is dumped on trace window.
however, this may be altered in InitInstance():
afxDump.m_pFile = pFile;
cleanup code in ExitInstance():
afxDump.Flush();
afxDump.Close();
delete afxDump.m_pFile;
afxDump.m_pFile = NULL;
