I have a simple program listed below:

#include <iostream.h> #include <stdlib.h> #include <math.h> void Goto_XY(int x, int y); void main(void) { Goto_XY(10,10); cout << "Well fishsticks!" << endl; } void Goto_XY(int x, int y) { _asm { mov ax,2 mov dl, Byte Ptr x mov dh, Byte Ptr y int 10h } }

Now that assembly code works perfectly under DOS and when assembled alone with ML and LINK it works great. But whenever the inline assembler deals with it, I have problems. Here it is. Whenever the program reaches and executes int 10h , I get a deadly blue-screen error . I just click enter and things continue, but after like 5 attempts to get int 10h to work, the whole system crashes. I just don''t get why it doesn''t work. Can''t we still call interrupts under Windows? Do I have to use those special 32-bit registers!? Oy...

You can''t call interrupts using in Windows. You will have to
resort to Direct X or use the Windows API.

Actually I wasn''t planning on anything close to that. I simply wanted a fast way to move the cursor around for some console type game, as opposed to the slow-as-hell escape sequences. I was also going to do the same for things like scrolling, etc.

use the gotoxy() call from conio.h

yes you have to use 32bit registers if you compile with MSVC v4.2+

If you compile with a DOS compiler, you can only use 16bit registers (with the exception of Watcom C v10?, which is where all that DOS4GW stuff came from)

I use 16-bit registers in MSVC6 all the time and they''ve always worked fine...

Sorry no such thing as gotoxy() in MSVC

There's even a gotoxy type api call for dropping text in a window...

Maybe gotoxy was a borland extention... I swore it was in conio.

I've gone completely linux at home so I don't have any actual windows development libs/source laying around on any of my machines. Regardless, I believe your stuck with using the functions defined in wincon.h like this for example. Most, if not all, of the legacy DOS support that used to be with MSVC is all but vanished since 4.0 I believe. Of course, I could be wrong...
