c++11 - Move CComBSTR to std::vector? -

is there way move ccombstr object std::vector without copying underlying string? seems following code doesn't work.

ccombstr str(l"somestr"); std::vector<ccombstr> vstr;  vstr.push_back((ccombstr)str.detach()); 

your code doesn't work because detach gives bstr, not ccombstr. have used std::vector<bstr> vstr, long realise bstr points first character of string, there's length prefix before memory points (see, e.g. bstr (automation)), you'd need careful managing it.

alternatively, have used

ccombstr str(l"somestr"); std::vector<ccombstr> vstr;  vstr.push_back(str); 

which make copy of string.

the msdn page on ccombstr not indicate has move-semantics, might have been added code without documentation being updated. don't think though, in case std::move solution in answer same second example: simple copy.
