Hello to all Forum Members!

I'd like to ask whether anyone can give me some advice on where to start looking for information about drawing graphics (ie pixels) to the DOS console available in Windows XP. Basically I've some routines that I used many years ago but I just can't seem to get them to work anymore. I'm not the most experienced 'coder' in the world but I can get by... usually! I am assuming this CAN be done... after all some of the simpler programs I wrote and compiled back then work in XP, as do some of the older games programs I bought at that time...

I'm using XP and Visual C++ 6 with SP6.

Thanks for any help you can provide

p.s. please, please don't tell me it's going to have to be DirectX or nothing

The "DOS console available in Windows XP" is not DOS, which is likely why you've been told to abandon this effort in favor of other APIs.

Thanks for the quick reply!

I guess that means this is a no-go, no way around it idea? I'll have to bin that recently acquired Abrash book then!

Thanks for your help, I'll be back soon cos I've got a scheduling problem to ask about (no, I'm not a CS major asking about homework!)

How were you doing it before? Was it a Microsoft compiler or another one, like Borland? Unless VC++6 removed the "DOS" graphics functions, you should still use it. I don't have VC++6 install.

Just because does not mean DOS-style graphics don't work anymore. Even old TSR's still work in ""not-really-DOS" mode, as well as most graphics games I used to play. I've built some recently.

Hello, again!

If my memory serves me it was a Microsoft C compiler but I can't remember which...
Very small snippit of code:

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

// Global Variables
int OldMode;

// Function Declarations
void OpenGraph();
void CloseGraph();

// Main Program
void main()
{
OpenGraph(); // open graphics mode 0x13
getch(); // wait for a keypress
CloseGraph(); // back to user's original mode
}

Anyway of getting this to compile and work?!

Find out what the functions aren't defined in your current compiler. Then either
1) find out if the functions still exist in the documentation and how to use them
2) find out if those functions have been replaced with new functions and modify the code
3) write your own versions of the functions that no longer exist
4) search for replacement functions in packages off the web that will work with your new compiler

That's about it...
