    There are some API calls to do this, but if you are new to them check out the following classes.

    In ATL - CComBSTR,
    In COM - _bstr_t

    Check it out,

    Just another thing:
    BitStrings are length preceeded (in a wrapper pointer in general at *p-1, and in VC++ 0 terminated (but i'm not sure about VB). So use SysAllocString and SysFreeString to allocate / free properly.
