positioning the cursor(plz help)

[rajatkochhar]

Well i m new to hardware programming in C. I tried to position
the curser at the required position but i m not confident about
this. The problem seems to be with video pages !!!!

 include <stdio.h>
#include <conio.h>
#include <dos.h>
#include<stdlib.h>



 void movetoxy()
 {
 
   union REGS inregs,outregs;
   inregs.h.ah=2;
   //fflush(stdin);
   //fflush(stdout);
    printf("\n Enter the row number");
    scanf("%d",&(inregs.h.dh));
    printf("\n Enter the coloumn number");
    scanf("%d",&(inregs.h.dl));
     

   /* i tried to make the following field 1,2 or comment it but of  
     no  use*/
      inregs.h.bh = 0;  //set the video page 
    int86(16,&inregs,&inregs);
} 

 int main(void)
 {
   clrscr();
   movetoxy();
   printf("Hello");
   return 0;
 }

What operating system?
What compiler are you using?

[Prelude]

>What operating system?
Probably Windows XP.

>What compiler are you using?
It looks like some version of Turbo C or C++.

>movetoxy();
Have you tried checking your compiler's documentation to see if it supports gotoxy()?

[rajatkochhar]

I am using windows XP and turbo c++ 3.0.
it supports gotoxy().

but i want to invoke ROM-BIOS function int86.

Hey rajatkochhar, good luck with that. I sure hope you get it to work some day!

>I am using windows XP and turbo c++ 3.0.
Now, you see, I was joking about Windows XP, with a glimmer of hope that you were actually using an operating system that matched your dinosaur of a compiler.

Repeat after me: "I <state your name> will not try to use a 16-bit real-mode compiler designed for DOS on a 'state of the art' 32-bit protected-mode operating system. I <state your name again> realize that such an action is stupid in the extreme and I don't want to be associated with the dozen a day idiots who show up on Cprog with a compiler and operating system that were released decades apart".

Try this

	union REGS regs;
	regs.h.ah=0x02;		//video function 2 to move cursor
	regs.h.bh=0x00;		//video screen 
	regs.h.dh=col;		//cursors column position
	regs.h.dl=row;		//cursors row position
	int86(0x10,&regs,&regs);

The compiler you are using is really old .. I suggest you start using something new..

[rajatkochhar]

Thanx u all for your suggestions.
suggest some new C compiler ...... borland,miracle,lcc win32,Dev-C++

[vasanth]

I use gcc on linux.. and dev-c++ which comes with a gcc port on windows

I used to use LCC win32 , it has some nice features, and compilation is very fast. I got sick of all the bugs though. Now I use dev c++ like many others on this forum.

class PureClass{};

[Prelude]

class PureClass{};

That's a little extreme, I think. But if it makes you feel better then who am I to say otherwise?

[dwks]

Not miracle.
