whereas typeid is a "give me the exact type of this object" operation to discover the actual type of an object. The latter is an inherently simpler operation that ought to be faster. The latter (

Add theDECLARE_DYNAMICmacro to the header (.h) module for the class, then include that module in all .cpp modules that need access to objects of this class. If you use theDECLARE_DYNAMICandIMPLEMENT_DYNAMICmacros as described, you can then use theRUNTIME_CLASSmacro and theCObject::IsKindOf...
