Differentiate Normal Dll To Com Dll? |
|
Answer» COM Dll exposes Interface on the contrary to normal DLL that exports functions. Clients create the POINTER to COMDLL's interface to call the methods defined by the COMPONENT that implements the interface. That results in isolation of IMPLEMENTATION and definition of method in the interface. Client doesnt need to RELINK or recompile the CODE if method in the com dll changes as far as the definition of the interface remains same.
