[Bhavesh1978]

well i have my mouse working and now im trying to make my exit button working when the mouse clicked onto exit button and it will exit the application


here is my coding for the mouse function to exit the application

............... ............... ............... ............... ............... ............... ............... .........

//The function getmousepos gets the position of the mouse alongwith the mouse button state. Like which
//button is pressed 1,2. If button =1 then it is left mouse and if it is 2 then right mouse button click.

void getmousepos(int *button,int *x,int *y)
    {
    char *ss;
    union REGS i,o;
    i.x.ax=3;
    int86(0x33,&i,&o);
    *button=o.x.bx;
    *x=o.x.cx;
    *y=o.x.dx;
    }
 
 
 
//The below loop executes until anything is pressed and then getmousepos is called to get the position of
//the mouse and if it falls in between x>=70 && x<=100 && y>=410 && y<=420 then exit from the program.
//void thisismycode()
{
     while(!kbhit())
     {
      getmousepos(&button,&x,&y);
      if((button&1)==1)
      {
        getmousepos(&button,& x,& y);
        if(x>=70 && x<=100 && y>=410 && y<=420)
         exit(0);
      }
     }
 
 }

[Bhavesh1978]

where u define these variables ??????

how you mean where i define these variables???
well im using old version of turbo c

[horace1]

how you mean where i define these variables???
well im using old version of turbo c

need to define button, x and y and initialise the mouse - try this as a test program

int main()
{
     int button, x,y;                        // << define variables
    union REGS registers;                  /* variable to hold 8086 registers */
 
    registers.x.ax = 0;                          /* reset the Microsoft mouse */
    int86(0x33, &registers, &registers);
     while(!kbhit())
     {
      getmousepos(&button,&x,&y);
      printf("%d %d %d \n", button, x, y);
      if((button&1)==1)
      {
        getmousepos(&button,& x,& y);
        if(x>=70 && x<=100 && y>=410 && y<=420)
         exit(0);
      }
     }

hi.

I have managed to correct from your code to mine.. some how i got an error saying

please check above thanks

Declaration is not allowed here
Declaration syntax error
Declaration missing ;
function should return a value

[DeMan]

I can see two implementations of main. The second one comes ion the middle of the first, and I suspect the parentheses are mixed up as a result. So: get rid of the second "int main()" and then make sure all your parentheses line up as required...

i have managed to get rid of the main int() in the middle.. still same error message

please help any1

[DeMan]

Might like to move the iont and union declarations (where the int main() originally was) up to the top of teh method.....
