How can I convert an int to BSTR

I would like to convert an int to BSTR. I'm using createTextNode in MSXML which accepts BSTR. H开发者_如何学Cow can I do that please?

Probably not efficient but first convert to a string and then you can simply convert that (untested):

std::wstring convertToString(int value)
{
    std::wstringstream ss;
    ss << value;
    return ss.str();
}

_bstr_t theConverted(convertToString(42).c_str());

int number = 123;
_bstr_t bstr = (long)number;
