在Visual Studio 2005输出窗口中捕获cout？

#include<iostream>
#include <sstream>
#include <streambuf>

class RedirectCoutBuf : public std::streambuf
{
public:
    RedirectCoutBuf(std::streambuf* originalCoutBuf, std::ostringstream& oss) : m_originalCoutBuf(originalCoutBuf), m_oss(oss) {}

    virtual ~RedirectCoutBuf() {
        // 将缓冲区内容输出到原始输出缓冲区
        m_originalCoutBuf->sputn(m_oss.str().c_str(), m_oss.str().size());
    }

    virtual int overflow(int c) {
        if (c != EOF) {
            m_oss.put(c);
        }
        return c;
    }

    virtual std::streamsize xsputn(const char* s, std::streamsize n) {
        m_oss.write(s, n);
        return n;
    }

private:
    std::streambuf* m_originalCoutBuf;
    std::ostringstream& m_oss;
};

int main()
{
    std::ostringstream oss;
    RedirectCoutBuf buf(std::cout.rdbuf(), oss);
    std::cout.rdbuf(&buf);

    std::cout << "Hello, World!"<< std::endl;

    // 输出将被重定向到oss中
    std::cout.rdbuf(buf.m_originalCoutBuf);

    // 输出oss中的内容
    std::cout << "Redirected output: " << oss.str()<< std::endl;

    return 0;
}
