Stdout in MFC. You can use cout!

Original Source: http://www.halcyon.com /~ AST/dload/guicon.htm.

I modified it and merged it into a head file named guicon. h. After debugging in vs2005, some code has been modified to adapt to 64-bit compilation. The usage is not much said. You only need to call redirectiotoconsole () once before use. Very simple.

# Ifndef _ guicon_h __

# DEFINE _ guicon_h __

# Ifdef _ debug

# Include <windows. h>

# Include <stdio. h>

# Include <fcntl. h>

# Include <Io. h>

# Include <iostream>

# Include <fstream>

# Ifndef _ use_old_iostreams

Using namespace STD;

# Endif

// Maximum mumber of lines the output console shocould have

Static const word max_console_lines = 500;

Void redirectiotoconsole ();

Void redirectiotoconsole ()

...{

Int hconhandle;

Handle lstdhandle;

Lele_screen_buffer_info coninfo;

File * FP;

// Allocate a console for this app

Allocconsole ();

// Set the screen buffer to be big enough to let us scroll text

Getconsolescreenbufferinfo (getstdhandle (std_output_handle ),

& Coninfo );

Coninfo. dwsize. Y = max_console_lines;

Setconsolescreenbuffersize (getstdhandle (std_output_handle ),

Coninfo. dwsize );

// Redirect unbuffered stdout to the console

Lstdhandle = getstdhandle (std_output_handle );

Hconhandle = _ open_osfhandle (int_ptr) lstdhandle, _ o_text );

Fp = _ fdopen (hconhandle, "W ");

* Stdout = * FP;

Setvbuf (stdout, null, _ ionbf, 0 );

// Redirect unbuffered stdin to the console

Lstdhandle = getstdhandle (std_input_handle );

Hconhandle = _ open_osfhandle (int_ptr) lstdhandle, _ o_text );

Fp = _ fdopen (hconhandle, "R ");

* Stdin = * FP;

Setvbuf (stdin, null, _ ionbf, 0 );

// Redirect unbuffered stderr to the console

Lstdhandle = getstdhandle (std_error_handle );

Hconhandle = _ open_osfhandle (int_ptr) lstdhandle, _ o_text );

Fp = _ fdopen (hconhandle, "W ");

* Stderr = * FP;

Setvbuf (stderr, null, _ ionbf, 0 );


// Make cout, wcout, Cin, wcin, wcerr, cerr, wclog and clog

// Point to console as well

IOS: sync_with_stdio ();

}


// End of File
# Endif
# Endif
