Dynamic Object Creation

  • Artikkeli

This article explains how to create an object dynamically at run time. The procedure uses run-time class information, as discussed in the article Accessing Run-Time Class Information.

Dynamically create an object given its run-time class

  1. Use the following code to dynamically create an object using the CreateObject function of the CRuntimeClass. On failure, CreateObject returns NULL instead of raising an exception:

    CRuntimeClass* pRuntimeClass = RUNTIME_CLASS(CMyClass);
CObject* pObject = pRuntimeClass->CreateObject();
ASSERT(pObject->IsKindOf(RUNTIME_CLASS(CMyClass)));
