cin and binary mode

[manimau]

Is there any chance of slightest light at the end of the tunnel in pursuing
the cin and binary mode operation together?

I am trying to see if I can open the cin in binary mode for read operation.
I am using VC++ with VS .NET 2003

While using VS 6.0, it was a piece of cake, but since there were a lot of
things just removed in VC++ .NET 2003 version, I am having a hard time
converting this little piece of code....

previously with VS 6.0 it was,

istream_withassign myFile;
filebuf *myFileBuf;
........
myFileBuf = new filebuf (_fileno(stdin));
myFileBuf->setmode(filebuf::binary);
myFile = myFileBuf; // stream object is stream buffer

if (!(myFile.read(data, nBytes)))
{
if (myFile.eof())
{
status = M_EndOfFile;
}
else
......
}

Which worked just fine.
Any ideas or hopes of converting it to VC++ .net 2003?

I have done something like this.... which obviously does not work..... It
reads the EOF before I expect it to. And it may be something with the cin not
opened in binary mode.

std::istream* myFile;

...........

myFile = &std::cin;

if (!(myFile->read (reinterpret_cast<char*>(data), nBytes)))
{
if (myFile->eof())
{
status = M_EndOfFile;
}
else
..........
}

I have posted this already in vc.languages. Since I was not sure if that was
the correct place to post, I am reposting it here hoping it is read by
different set of people. If not, please accept my apologies.

Thanks in advance,
