Please guide me

quddos (9)
how can i exit a runnig program by pressing "esc " key.
actually i want to use it in my minesweeper assignment.the game is complete .
but only that portion is incomplete.
Bazzy (6281)
Are you using some external libraries?
quddos (9)
yes i am using
stdlib,conio,string,stdio,
Bazzy (6281)
conio.h has the getch() function which returns an ascii code corresponding to keyboard input, Esc key should be 27.

--Function from conio aren't good if you can use curses, windows or something similar is better--
quddos (9)
Guy i want a statement that wait for esc key through out the running process.the moment we press esc key our program should exit.could you please tell me some statements regarding this problem.
Bazzy (6281)
As I said you can use getch:
1
2
3
4
5
6
 
#include <conio.h>
int main()
{
   while(getch()!=27);
   return 0;
}

You can use windows API:
1
2
3
4
5
6
 
#include <windows.h>
int main()
{
    while( !GeatAsyncKeyState( VK_ESCAPE ) ); 
    return 0;
}

You can use curses
1
2
3
4
5
6
7
8
 
#include <curses.h>
int main()
{
    WINDOW *wnd = initscr();
    while (getch()!=27);
    endwin();
    return 0;
}


And there are lots of other different ways to do this

i was unable to implement your code in my program.when i run your code seperately it works perfectly.i need a bit more kind help from you.

Please use [code][/code] tags
I suggest you to use loops instead of gotoes

When you want to have the option of exiting your program by pressing Esc?
awasteoflife (73)
I'm guessing he wants it where he's written getch() at the end, so code should be:

hi buddy.whats about that error.i dont understand this error.


regards
Quddos

241 F:\Mines new.cpp `GeatAsyncKeyState' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)
quddos (9)
hi Bazzy.i want to terminate the program at any moment.like we open a windows we can exit it at any time by clicking close button.i want this feature in my program.hope you will understand my problem.thanks



regards
Quddos
Bazzy (6281)
That was a typo, change GeatAsyncKeyState to GetAsyncKeyState
awasteoflife (73)
oh dam... I noticed that it was a typo when you wrote it, and was going to point that out but then forgot a copied+pasted your code

quddos (9)
hi.it still cant solve my problem.by using your code the program terminates when game is over .ie a mine is selected.please help me .
Bazzy (6281)
Try inserting this line if ( GetAsyncKeyState( VK_ESCAPE ) ) return 0; just after tag2, if the user pressed escape during the previous input, the program should terminate
quddos (9)
it dont work program doesnt exit .
