no.. I got that code from friend..

I want to ask if there is any way to hid the cursor, the code is just an example..

I just found that conio.h have function

Code:

#define _NOCURSOR 0

but it also doesn't work

Whatever the answer is, it will depend on that information.

I'm using windows xp sp 2 and using dev c 4.9.9.2..

In DOS you need to either update the hardware registers directly, or use a BIOS call - you hide the cursor by setting the start and end row of the cusor size to the same value if I remember right [or was it to set both to a "higher value than the number of rows of the text" - it is about 15 years since I did this, so I can't quite remember... (I think I'm doing quite well in remembering roughly how it's done!) ]

is it really neccesary to update? because I want to give that program to my friends.. do I have to update all of their hardware registers?

how to use BIOS call?

thanks..

what I need to include? conio2.h?

sorry for the double post..

I already include windows.h and wincon.h but still doesn't work..

I got this error message
