Here's a useful tokenization function. It doesn't use streams, but can easily perform the task you require by splitting the string on commas. Then you can do whatever you want with the resulting vector of tokens.

/// String tokenizer.
///
/// A simple tokenizer - extracts a vector of tokens from a 
/// string, delimited by any character in delims.
///
vector tokenize(const string& str, const string& delims)
{
    string::size_type start_index, end_index;
    vector ret;

    // Skip leading delimiters, to get to the first token
    start_index = str.find_first_not_of(delims);

    // While found a beginning of a new token
    //
    while (start_index != string::npos)
    {
        // Find the end of this token
        end_index = str.find_first_of(delims, start_index);

        // If this is the end of the string
        if (end_index == string::npos)
            end_index = str.length();

        ret.push_back(str.substr(start_index, end_index - start_index));

        // Find beginning of the next token
        start_index = str.find_first_not_of(delims, end_index);
    }

    return ret;
}
