[wabc]

in a COM object,the class implement some interface can have a destruct function? when the destruct fuction is executed?

[Joaquin M Lopez Munoz]

Typically, COM objects implement the IUnknown interface, which controls the lifetime of an object via methods AddRef and Release. This is usually the preferred method for acquiring/passing around/destroying an object, instead of some ad hoc destruction function. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
