I am interested in writing a program in Turbo C that is able to use a mouse. Unfortunately, I have been unable to find anything decent in any of the books I have looked in (the only solution I have seen is to read the data straight from the serial port). I figure that it will invlove installing interupt handlers that look at the interrupt vectors hooked by the mousedriver, but I have not done anything like that before and am a little apprehensive on how to go about it. Can anyone out there point me in the direction of a book to read, or even better, some C source code (such as something on simtel etc) showing me how do use the mouse?

These are listed in the documentation which comes with the mouse (at least, they used to be for Microsoft). I believe they're also documented in the interrupt list maintained by Ralf Brown. If you really want a book on programming the mouse, Microsoft publishes one, complete with disc. I believe it's about 40 dollars. One of the summary editions of DOS extensions also lists the mouse interrupts (runs about 6 bucks). Good luck Bill -- Bill de Beaubien / wjb@moscom.com

I use that source in one of my programs and I have it around here somewhere, but I am unsure as to whether I could mail it to you. I'm sorry that I can't give you the exact issue number (I'm here at work, not at home). If you wish, e-mail me and I will get the issue and address to write for back- issues.

I'm trying to get a set of colors so I can use text mode but
with a graduation from deep red->white->deep green. I'm using
a VGA and Microsoft C 5.1, the following code sets up the colors
long newcolormap[] =
{
0x000000L, 0x00003fL, 0x0a0a3fL, 0x14143fL,
0x1e1e3fL, 0x28283fL, 0x32323fL, 0x1f1f1fL,
0x323f32L, 0x283f28L, 0x1e3f1eL, 0x143f14L,
0x0a3f0aL, 0x003f00L, 0x3f0000L, 0x3f3f3fL
};
void setupvga(void)
{
_remapallpalette(newcolormap);
}
but I have to use the Norton Command Centre to change the normal
pallete colors (0,1,..,5,20,7,56,57,..,63) to sequential numbers
(0,1,...,15) as the colors at 20 & 56 .. 63 don't change. Does any
one know how to set the pallete colors like NCC does or alternately
how to set these colors over 16.stever@Octopus.COM (Steve Resnick ) (11/15/90)

According to my references here, BIOS int 10H function 10H sets the palette registers (like NCC does) for EGA/VGA display adapters. The information is quite lengthy however. I am relatively sure that this is listed in Ralf Brown's interrupt list. You may want to look there. Hope this helps....
