CObject Class: Dynamic Object Creation

Home |  Overview |  How Do I |  FAQ

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

To dynamically create an object given its run-time class

• Use the following code to dynamically create an object by using the CreateObject function of the CRuntimeClass. Note that 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 ) ) );
