Remarks

Removes all the pointers from this array but does not actually delete the CObject objects. If the array is already empty, the function still works.

The RemoveAll function frees all memory used for pointer storage.
That's not the problem here as CStringArray strores CStrings and not pointers to objects. RemoveAll in a CStringArray deletes the CStrings as well.
