    Thumbs up Colour question

    Is it possible to colour the ENTIRE background of a console program, rather than just the background behind the text?

    Here's one way, I'll bet there are better ways. But this is the best I can do.

    Code:
    
    #include "stdafx.h"
    #include <windows.h>
    #include <iostream> 
    
    using namespace std; 
    
    HANDLE hStdout, hStdin; 
    CONSOLE_SCREEN_BUFFER_INFO csbiInfo; 
    BOOL SetBackForeColors(const HANDLE hConsole, const DWORD );
    
    int main(int argc, char* argv[])
    {
    	hStdout = GetStdHandle(STD_OUTPUT_HANDLE); 
    	if ( hStdout == INVALID_HANDLE_VALUE ) 
    	{
    		cout << "GetStdHandle" << endl; 
    		return 1;
    	}
    
    	SetBackForeColors( hStdout, ( FOREGROUND_GREEN | BACKGROUND_RED )  );
    
    	cout << "Ye ha..." << endl;
    
    	cout << endl << endl << endl << endl;
    
    	cout << "                           Yo-ho" << endl << endl;
    
    	return 0;
    }
    
    
    
    BOOL SetBackForeColors(const HANDLE hConsole, const DWORD dwColor ) 
    {   
    	COORD coordScreen = { 0, 0 };		/* here's where we'll home the cursor */   
    	BOOL bSuccess = TRUE;   
    	DWORD cCharsWritten;   
    	CONSOLE_SCREEN_BUFFER_INFO csbi;	/* to get buffer info */   
    	DWORD dwConSize;					/* number of character cells in the current buffer */    
    	
    	/* get the number of character cells in the current buffer */   
    	bSuccess = GetConsoleScreenBufferInfo(hConsole, &csbi);   
    	dwConSize = csbi.dwSize.X * csbi.dwSize.Y;   
    	
    
    	if ( ! SetConsoleTextAttribute( hStdout, dwColor  ) ) 
    		cout << "SetConsoleTextAttribute" << endl; 
    
    	/* fill the entire screen with blanks */   
    	bSuccess = FillConsoleOutputCharacter(hConsole, (TCHAR) ' ',  dwConSize, coordScreen, &cCharsWritten);   
    
    	/* get the current text attribute */   
    	if( bSuccess )
    		bSuccess = GetConsoleScreenBufferInfo(hConsole, &csbi);   
    	
    	/* now set the buffer's attributes accordingly */  
    	if( bSuccess )
    		bSuccess = FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);   
    	
    	/* put the cursor at (0, 0) */   
    	if( bSuccess )
    		bSuccess = SetConsoleCursorPosition(hConsole, coordScreen);   
    
    	return bSuccess; 
    }

    There is different ways of doing it. It all depends on your compiler. If your using MS Visual C++, the way Dang did it is the best. If you are using a DOS compiler, then it is simple. use
    textbackground(3); //or whatever number for a color
