I'm basically trying to do this....

i->name = CComBSTR((char *)name);

Without using the CComBSTR method because when I use it with Microsoft Application Verifier it's giving me an error.  So I need another way around it....

Try _bstr_t wrapper. Or use SysAllocString API, without any wrappers.

Ok... Should I be using the Detach or CopyTo functions if I'm passing the i pointer(i->name) into another function.

If another function is supposed to keep BSTR passed to it, use Detach method:

_bstr_t str(name);
OtherFunction(str.Detach());    // now other function is responsible for releasing BSTR
