how do i check if an object has been created ??
i.e.

CMyObject *theObject;

...
if (...){
  theObject = new CMyObject;
}

delete theObject; // CANT kill object if not been created with 'new'
...

i need something like:
if ( HasBeenCreated(theObject) )

CMyObject *theObject;
theObject = NULL;

// Create the object depending on some condition.
if (...){
  theObject = new CMyObject;
}

// Delete the object
if (theObject != NULL)
  delete theObject;

Since you set the object to NULL initially, delete will be called only if it has been created.

Hope this helps.
