How can I convert an int to BSTR

Question

I would like to convert an int to BSTR. I'm using createTextNode in MSXML which accepts BSTR. How can I do that please?

Answer 1

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());

Data Type Conversion Functions [Automation] (MSDN), see "Functions to convert to type BSTR" section.
