C/Any special tricks for textcolor & textbackground?

Question
1. With the "textbackground" function, how do I get all 16 background colors, instead of 8 background colors?
2. With the "textbackground" function, how can I get the 8 high intensity background colors, instead of the 8 low intensity background colors?
3. With the "textbackground" function, how can I set it back to the regular 8 low intensity background colors, instead of the 8 high intensity background colors?
4. Besides the "textattr" function, "textbackground" function, or "textcolor" function how can I get a bordered-colored frame over the screen? In GW-BASIC the command "COLOR ,,4" puts a red bordered-colored frame over the screen. How can I do that in Turbo-C, instead?
5. Does the "int86" function deal with colors?
Could you please E-Mail me back at joshblaize@juno.com ?
1. Its not possible with that function because its deniced in such a way !
2. same !
4. Possible but with little pain !
5. Its just an interrupt generating function , ROM-BIOS fuctions didn't have separate routine for that task!
Here i give you some code , i think it will help you !
/*
Create a window border in a 80 x 50 mode
if your computer support typical 80 x 25 just change the last argument
in the window() function.
*/
#include <conio.h>
void main()
{
textbackground(RED);
window(1 , 1 ,80 , 50);
clrscr();
textbackground(BLACK);
window(2 , 2 , 79 , 49);
clrscr();
getch();
}

| Comment | I was looking around on the internet to see about getting high-intensity back ground colors and I found a site that showed you how to do it in Pascal. I didn't know much about Pascal, but I was able to convert this code to Turbo-C. 16 background colors is done by: #include <conio.h> #include <dos.h> void brightness(int x) { union REGS reg; reg.h.ah = 0x10; reg.h.al = 0x03; reg.h.bl = x; int86(0x10, ®, ®); } void main () { textmode(3); textbackground(6); textcolor(1 128); brightness(0x00); clrscr(); cprintf("Blue over yellow.\n\r"); getch(); brightness(0x01); textbackground(0); textcolor(7); clrscr(); cprintf("Back to normal.\n\r"); getch(); } There's always something new to learn. Here's another program: /* Poking and Peeking characters on the screen */ #include <conio.h> #include <dos.h> void main () { int screen; screen=0xB800; /* Color Graphics Computer */ /* screen=0xB000; * Computer Without Graphics Card */ textmode(1); clrscr(); pokeb(screen,1000,6); pokeb(screen,1000 1,9); cprintf("Blue Spade.\n\r"); cprintf("Peek Address of 1000: %d \n\r",peekb(screen,1000)); cprintf("Peek Address of 1001: %d \n\r",peekb(screen,1001)); getch(); } Thanks... | ||
