This is working fine except I am not able to print messages/errors on
command line using cout .

Is there any way that my MFC dialog based application could do this?

There is surprisingly little difference between windowed and console
applications. Windowed applications normally don't have a console, but they
can create one with AllocConsole(). Console applications don't normally
display their own windows but they can call CreateWindow[Ex](), GetMessage()
etc.

If you are content to use Win32 I/O calls, you can use AllocConsole() and
WriteConsole().

If you want to use C or C++ output, then it's a little more work. See below.

// Associate console with standard ouput device

fd = _open_osfhandle(reinterpret_cast<long>(hCon), 0);
fp = _fdopen(fd, "w");

*stdout = *fp;
setvbuf(stdout, NULL, _IONBF, 0);
