How to handle RTTI in MFC ?

Answer Posted / n.venkateshwara rao.

RTTI (Run Time Type Identification) in MFC can be handled
by using the class CRunTimeClass.

But CRunTimeClass can be use to identify the type of the
class which are derived from CObject.

For eg -

void MyFunction()
{
CObject *mObject = new MyClass;
if(mObject->IsKindOf(RUNTIME_CLASS( MyClass) ) )
{
printf("Class is of type MyClass\n");
}
else
{
printf("Class is of type someotherclass\n");
}
}

We can use "type_info" for other type of classes which are
not derived from CObject.
