Change entire console background color (Win32 C++) - c++

Question

How can I change the entire console's background color? I've tried SetConsoleTextAttribute and it only changes the background color of new text.
I effectively want the entire console to turn red when a serious error arises.
Thanks to everyone who attempts to help.

Answer 1

Try something like:
system("color c2");

I think the FillConsoleOutputAttribute function will do what you need. Set it to the starting coordinate of the console, and set nLength to the number of characters in the console (width * length).
BOOL WINAPI FillConsoleOutputAttribute(
__in HANDLE hConsoleOutput,
__in WORD wAttribute,
__in DWORD nLength,
__in COORD dwWriteCoord,
__out LPDWORD lpNumberOfAttrsWritten
);

I know this is an old question, but how about this code:
#include <windows.h>
#include <iostream>
VOID WINAPI SetConsoleColors(WORD attribs);
int main() {
SetConsoleColors(BACKGROUND_BLUE | FOREGROUND_RED | FOREGROUND_INTENSITY);
std::cout << "Hello, world!" << std::endl;
std::cin.get();
return 0;
}
VOID WINAPI SetConsoleColors(WORD attribs) {
HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFOEX cbi;
cbi.cbSize = sizeof(CONSOLE_SCREEN_BUFFER_INFOEX);
GetConsoleScreenBufferInfoEx(hOutput, &cbi);
cbi.wAttributes = attribs;
SetConsoleScreenBufferInfoEx(hOutput, &cbi);
}
As far as I know this code should work on Windows Vista and later versions. By the way, this code is based on this article (mainly the sources on the article): http://cecilsunkure.blogspot.fi/2011/12/windows-console-game-set-custom-color.html

It can be done and the whole background can be set to desired color with SetConsoleScreenBufferInfoEx. The code below should not mess with the previous console output, especially if it used colors:
#include "Windows.h"
void FlashConsoleBackgroundColor(int cntFlashes, int flashInterval_ms, COLORREF color)
{
CONSOLE_SCREEN_BUFFER_INFOEX sbInfoEx;
sbInfoEx.cbSize = sizeof(CONSOLE_SCREEN_BUFFER_INFOEX);
HANDLE consoleOut = GetStdHandle(STD_OUTPUT_HANDLE);
GetConsoleScreenBufferInfoEx(consoleOut, &sbInfoEx);
COLORREF storedBG = sbInfoEx.ColorTable[0];
for (int i = 0; i < cntFlashes; ++i)
{
//-- set BG color
Sleep(flashInterval_ms);
sbInfoEx.ColorTable[0] = color;
SetConsoleScreenBufferInfoEx(consoleOut, &sbInfoEx);
//-- restore previous color
Sleep(flashInterval_ms);
sbInfoEx.ColorTable[0] = storedBG;
SetConsoleScreenBufferInfoEx(consoleOut, &sbInfoEx);
}
}
int main()
{
printf("Flashing console BG: RED");
FlashConsoleBackgroundColor(20, 50, RGB(255, 0, 0));
printf("\rFlashing console BG: ORANGE\n");
FlashConsoleBackgroundColor(10, 100, RGB(255, 105, 0));
return 0;
}

HANDLE out = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(out, 0x9 | 0x70);
// text color from 0x1-0x9
// text background color from 0x10-0x90
system("color d1");
/*
Sets the default console foreground and background colors
COLOR [attr]
attr Specifies color attribute of console output
Color attributes are specified by TWO hex digits -- the first
corresponds to the background; the second the foreground. Each digit
can be any of the following values:
0 = Black 8 = Gray
1 = Blue 9 = Light Blue
2 = Green A = Light Green
3 = Aqua B = Light Aqua
4 = Red C = Light Red
5 = Purple D = Light Purple
6 = Yellow E = Light Yellow
7 = White F = Bright White
If no argument is given, this command restores the color to what it was
when CMD.EXE started. This value either comes from the current console
window, the /T command line switch or from the DefaultColor registry
value.
The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute
the COLOR command with a foreground and background color that are the
same.

This works for me. It changes the background color without messing up the foreground color of text already displayed, by changing each console character cell, one at a time. You will need to get the handle to your console output buffer, which I believe is done with GetStdHandle().
DWORD written = 0;
COORD writeCoord = {0};
WORD attribute;
for (int y = 0; y < consoleBufferLength; y++) // rows
{
for (int x = 0; x < consoleBufferWidth; x++) // columns
{
writeCoord.X = x; writeCoord.Y = y;
ReadConsoleOutputAttribute(consoleOutputHandle, &attribute, 1, writeCoord, &written);
attribute &= 0xFF0F; // zero the background color
attribute |= 12 << 4; // change the background color to red
FillConsoleOutputAttribute(consoleOutputHandle, attribute, 1, writeCoord, &written);
}
}

I have a dirty way here, but gives what you exactly want.
#include <windows.h>
hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole,30);
system("CLS");
console
