CONIO.H alternative for Dev-C++ IDE Users

[magicyte]

I've noticed that the standard conio.h for Dev-C++ doesn't include gotoxy() and other functions that are in relation to such. Here is an alternative to conio.h that I came up with for those of you Dev-C++ users:


#ifndef _ALT_CONIO_H_
#define _ALT_CONIO_H_

#include "windows.h"
#include "conio.h"
#include "time.h"

#define WIN_32_LEAN_AND_MEAN

void gotoxy(int x,int y);
void setx(int x);

void setcolor(unsigned short color);
void delay(unsigned long milisec);
void setcursor(int ctype);

void gotoxy(int x,int y)
{

SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos);
}

}

void clrscr(void)
{

setcolor(WHITE);
for(int y = 0; y < window.dwSize.Y; y++)
{
for(int x = 0; x < window.dwSize.X; x++)
{
gotoxy(x,y);printf(" ");
}
}
}

int getx(void)
{
CONSOLE_SCREEN_BUFFER_INFO window;
GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &window);
return window.dwCursorPosition.X;
}

int gety(void)
{
CONSOLE_SCREEN_BUFFER_INFO window;
GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &window);
return window.dwCursorPosition.Y;
}

int align(int align, char str[])
{
int x;
switch(align)
{
case 0:
x = (0);
break;
case 1:
x = (40-(strlen(str)/2));
break;
case 2:
x = (79-(strlen(str)));
break;
default:
printf("ERROR:\nalign(int align, char str[]) aborted.\nERROR CAUSE:\nnon-feasible parameter number in int align detected.");
getche();
exit(0);

if(strlen(str) > 79) {

exit(0);
}
else {
gotoxy(x,gety());printf("%s",str);
}
}

#endif

It is only 4KB large!! Hope this helps with everyday programming!

No, it is forbidden. As punishment, you are hereby forbidden from coding until you learn to indent properly.

In seriousness... it seems nobody's interested, so don't keep bumping. Most people don't code for the console in Windows. Those that do are probably *nix developers working with mingw32 anyway.

[magicyte]

Yup. That's me. Sure. Won't bump THIS one any more. Anyway, can you teach me how to indent properly? Please! Also, what is a 'nix' developer?

*nix is a common term for 'anything UNIXy' — GNU, BSD, AIX, Solaris, &c.

Indentation is quite simple: indent one 'tab' for each new block you enter. :) If you get a good editor, it'll even do it for you.

[magicyte]

I have a bad editor that does it for me and it is bad... Dev-C++... Yeah.

I == PC
I != UNIX

I use the 4.9.9.2 beta version of Dev-C++. Fairly new, 'tis.

[Twey]

I really do, and always have, recommended switching to Linux for new programmers. Most APIs developed by Microsoft, especially the low-level ones, are utter beasts to manage, and the system doesn't lend itself well to investigation and study.

As for your editor, I strongly suggest emacs, or XEmacs (http://xemacs.org/) for Windows.

[magicyte]

Okay. I've always wanted to do this. I will respond to you in JavaScript!!


<script type="text/javascript">
var i = "magicyte";
var UNIX = "operating system";
var MAC = "operating system";
var TOO_MUCH = "cannot buy now...";
var why_use_a_unix_or_mac_instead_of_windows = 1;
var compiler = 0;
var microsoft = 1;
var bloodshed = 0;

if(i != UNIX && i == TOO_MUCH) {
alert(what_do_I_do_q());
}
else if(i != MAC /* or whatever you said */ && i == TOO_MUCH) {
alert(what_do_I_do_q());
}

function what_do_I_do_q() {
return "What do I do???";
}

eval("tellim()");

function tellim() {
return "for(dev = compiler; dev != microsoft, dev == bloodshed; dev++);";
}

eval("doiteth()");

function doiteth() {
return "(why_use_a_unix_or_mac_instead_of_windows) ? alert(because('list')) : alert(because('list'));
}

function because(para) {
return para;
}
</script>

Please report any errors with my script.

From what I can see, mismatched quotes and eval() usage :)
var OSAdvocacy = {
