find this in your help files. I have never used
it myself but its implementation would seem to
answer your situation.

TOleString

TOleString wraps a BSTR.

Header
utilcls.h

Description

TOleString provides a convenient object wrapper for the Windows BSTR type. Because TOleString frees the BSTR in its destructor, there is no need to call SysFreeString to free the wrapped string.
