C++ How to download webpage to string without saving to disk - URLDownloadToFile not work

Question

How to download webpage into string without saving this page to disk in C++?

URLDownloadToFile MSDN function only saving page into disk.

Answer 1

Did you look up the other URLXXX functions mentioned thereof? How about: URLOpenBlockingStream?

//implement filestream that derives from IStream
class StringStream : public IStream
{
  StringStream(std::wstring buf) 
    {
        _refcount = 1;
        _mBuf = buf;
    }

    ~ StringStream ()
    {

    }
   // implement IUknown, IStream interfaces
   private:
    std::wstring _mBuf;
    long _refcount;
 };

See the default file based IStream implementation here.

Answer 2

But how to read that IStream to string? I got

IStream* pStream;
string text;

URLOpenBlockingStream(NULL, "http://www.mysexyserver.com/text.txt", &pStream, 0, NULL);
text =pStream;
cout << text << endl;

This not works
