To be or not to be (a console app)

[Joeman]

This seems like what you want:

#include <windows.h>
#include <iostream>
#include <cstdio>

bool IsAConsole( HANDLE Handle )
{
    DWORD Mode;
    return GetConsoleMode( Handle, &Mode ) != 0;
}

FILE* MapStdToConsole()
{   
    FILE* File = NULL;

    HANDLE StdOut = GetStdHandle( STD_OUTPUT_HANDLE );

    if( StdOut && AttachConsole( ATTACH_PARENT_PROCESS ) )
    {
        if( IsAConsole( StdOut ) )
            File = freopen( "CONOUT$", "w", stdout );
    }

    return File;
}

class cConsoleInitializer
{
    FILE* File;
public:
    cConsoleInitializer()
    {
        File = MapStdToConsole();
    }

    ~cConsoleInitializer()
    {
        if( File )
        {
            INPUT_RECORD InputRecord;

            InputRecord.EventType = KEY_EVENT;
            InputRecord.Event.KeyEvent.bKeyDown = TRUE;
            InputRecord.Event.KeyEvent.dwControlKeyState = 0;
            InputRecord.Event.KeyEvent.uChar.UnicodeChar = VK_RETURN;
            InputRecord.Event.KeyEvent.wRepeatCount = 1;
            InputRecord.Event.KeyEvent.wVirtualKeyCode = VK_RETURN;
            InputRecord.Event.KeyEvent.wVirtualScanCode =  MapVirtualKey( VK_RETURN, 0 );

            DWORD Written = 0;
            WriteConsoleInput( GetStdHandle( STD_INPUT_HANDLE ), &InputRecord, 1, &Written );

            fclose( File );

            FreeConsole();
        }
    }
};

Just construct a cConsoleInitializer.
