    The guy who did it? You mean the guy that typed exit or quit somewhere in some window? Please give some more information.

    should work

    I know I have posted this before but this is a small utility to work with to change the colors and change the location of text and what not. Works well with vc++.

    Code:
    #ifndef _CONSOLE_LIBRARY_INTERFACE
    #define _CONSOLE_LIBRARY_INTERFACE
    
    #include <windows.h>
    WORD cl_fc_param = 0;
    WORD cl_bc_param = 0;
    
    void text_color(bool red, bool green, bool blue, bool bright)
    {
    #ifdef _INC_IOSTREAM
    	cout.flush();
    #endif
    
    	cl_fc_param = 0;
    	if ( red ) cl_fc_param |= FOREGROUND_RED;
    	if ( green ) cl_fc_param |= FOREGROUND_GREEN;
    	if ( blue ) cl_fc_param |= FOREGROUND_BLUE;
    	if ( bright ) cl_fc_param |= FOREGROUND_INTENSITY;
    
    	SetConsoleTextAttribute( GetStdHandle(STD_OUTPUT_HANDLE), cl_fc_param|cl_bc_param );
    }
    void text_background(bool red, bool green, bool blue, bool bright)
    {
    #ifdef _INC_IOSTREAM
    	cout.flush();
    #endif
    
    	cl_bc_param = 0;
    	if ( red ) cl_bc_param |= BACKGROUND_RED;
    	if ( green ) cl_bc_param |= BACKGROUND_GREEN;
    	if ( blue ) cl_bc_param |= BACKGROUND_BLUE;
    	if ( bright ) cl_bc_param |= BACKGROUND_INTENSITY;
    
    	SetConsoleTextAttribute( GetStdHandle(STD_OUTPUT_HANDLE), cl_fc_param|cl_bc_param );
    }
    void text_loc(int x, int y)
    {
    #ifdef _INC_IOSTREAM
    	cout.flush();
    #endif
    	COORD cursor_coordinates;
    	cursor_coordinates.X = x;
    	cursor_coordinates.Y = y;
    	SetConsoleCursorPosition( GetStdHandle(STD_OUTPUT_HANDLE), cursor_coordinates );
    }
    
    void console_title(const char* title)
    {
    	SetConsoleTitle(title);
    }
    
    #endif
    Anyways, here is a snippet of code that should help you accomplish what you want. What it attempts to do is set up a string that it as long as the buffer screen and print it to the string (there probably is a better way, i never tried system("CLS") with colors active). Then it sets the text location to the center minus an offset for the name length and prints it out.

    Code:
        void ShowEndScreen(const char * name)
        {
             const int xmax = 80;
             const int ymax = 25;
    
             int buff[xmax*ymax];
             memset(buff, 0, xmax*ymax); // string.h
    
             text_color(0, 1, 0, 0); // red green blue bright
             text_background(0, 1, 0, 0); // same
             text_loc(0, 0);
    
             cout << buff;
    
    
             text_loc( ymax/2, xmax/2 - strlen(name)/2 ); // I think the row is mentioned first, you might want to flip
             text_color(1, 1, 1, 1); // same as above
    
             cout << name;
        }

    not really

    The default values of the text color and background can be set in the console window. For example, open the command prompt and left click the icon in the top-left corner and select defaults. This will allow you to set the initial text color and background of any console program. As far as the default values for the text location is concerned, I believe that is always zero.

    Normally, the text color is dark white and the background is black. That is what I assume in tha small header file. It is possible to queue the system to find the current color and background, but this would require either a seperate initheader() function or specifying all text color attributes (foreground and background) at once. My solution, if you're really worried about initial colors or such, just call text_color() and text_background() on startup.

    Oh yeah, in that last piece of code, you have to use the column number for the first paramater and row number for the second one. In other words, the dubious call to text_loc above should have its parameters swapped as I mentioned in the comment next to it.

    Oh and I hope you don't mind, I liked your little idea of the end screen option with the screen covered and a small message; so, I went ahead and made a function that did just that. Only mine also shows a little animation of lines coming from the left and right to cover what is currently on the screen before the message is shown.

    problem with this code...

    Genghis:
    i tried to use the function that you posted. however, as soon as my console window scrolls down i lose the ability to change the colors to anything else that the first set that i used. if you have any ideas please let me know.
