Thanks, I see where I was not using the correct constructor before. However, even when I use the proper one, I get the same results. I cannot get the '<<' operator to append to the original string that I pass using the stringstream constructor. It still begins at the first character and begins overwriting the string.

//constructor syntax explicit stringstream ( openmode mode = in | out ); explicit stringstream ( const string & str, openmode mode = in | out );

//updated code boost::shared_ptr< std::stringstream > sharedStream(new

std::stringstream("hello world", std::stringstream::out));

Is there something else I'm missing?

I think you have to use the "ate" or "app" openmode for that.

HTH,

Hi Eric, I tried and none of the following modes worked. boost::shared_ptr< std::stringstream > sharedStream(new std::stringstream("hello world", std::stringstream::out | std::stringstream::ate )); boost::shared_ptr< std::stringstream > sharedStream(new std::stringstream("hello world", std::stringstream::out | std::stringstream::app )); boost::shared_ptr< std::stringstream > sharedStream(new std::stringstream("hello world", std::stringstream::app )); boost::shared_ptr< std::stringstream > sharedStream(new std::stringstream("hello world", std::stringstream::ate )); Thanks, Ed
