StringStreams

Code:

---

/* string buf
stringstream ss;
int EmailBuf.ID;
*/
buf = "RETR ";
ss << EmailBuf.ID;
ss >> buf;

---

When i do this, the variable buf stays with the value "RETR ", it is like stringstream never existed.

Code:

---

#include <iostream>
#include <string>
#include <sstream>
int main()
{
        std::string buf("RETR ");
        std::stringstream ss;
        int ID = 6;
       
        ss << ID;
        ss >> buf;
        std::cout << buf;
        return 0;
}
/*
My output
6
*/

---

Seams to be problem somethere else

output should be RETR 6, but as i saw in your code it is ok, i will try some more in my program

No way. Maybe seeing a litlle bit more of the code...

Code:

---

                stringstream ss;
                buf = sock->ReceiveLine();
                if (buf[0] == '.')
                        break;

                Email EmailBuf;
                ss << buf[0];
                ss >> EmailBuf.ID;
                index = EmailBuf.ID;
                index--;

                buf = "RETR ";
                ss << buf;
                ss << EmailBuf.ID;
                ss >> buf;

becasuse the strignstream contains spaces you cannot use >> to read from it the whole string ( >> stops on the first space)

Code:

---

#include <iostream>
#include <string>
#include <sstream>
int main()
{
        std::string buf("RETR ");
        std::stringstream ss;
        int ID = 6;
       
        ss << buf << ID;
        buf = ss.str();
        std::cout << buf;
        return 0;
}
/*
My output
RETP 6
*/
