Thanks Richard, I couldn't think of that earlier. Thanks again

OS interrupts are only used in 16-bit MSDOS apps. More [here ] You can try this code for a WIN32 console app.

#include #include using namespace std;

int main()
{
HANDLE hIn;
HANDLE hOut;
COORD KeyWhere;
COORD MouseWhere;
COORD EndWhere;
bool Continue = TRUE;
int KeyEvents = 0;
int MouseEvents = 0;
INPUT_RECORD InRec;
DWORD NumRead;

hIn = GetStdHandle(STD\_INPUT\_HANDLE);
hOut = GetStdHandle(STD\_OUTPUT\_HANDLE);

cout << "Key Events   : " << endl;
cout << "Mouse Events : " << flush;

KeyWhere.X = 15;
KeyWhere.Y = 0;
MouseWhere.X = 15;
MouseWhere.Y = 1;
EndWhere.X = 0;
EndWhere.Y = 3;

while (Continue)
{
    ReadConsoleInput(hIn,
                     &InRec,
                     1,
                     &NumRead);

    switch (InRec.EventType)
    {
    case KEY\_EVENT:
        ++KeyEvents;
        SetConsoleCursorPosition(hOut,
                                 KeyWhere);
        cout << KeyEvents << flush;
        if (InRec.Event.KeyEvent.uChar.AsciiChar == 'x')
        {
            SetConsoleCursorPosition(hOut,
                                     EndWhere);
            cout << "Exiting..." << endl;
            Continue = FALSE;
        }
        break;

    case MOUSE\_EVENT:
        ++MouseEvents;
        SetConsoleCursorPosition(hOut,
                                 MouseWhere);
        cout << MouseEvents << flush;
        break;
    }
}

return 0;

}

Is this the header file? I need mouse.h for turbo c++. Thanks for the code.

I don't think this message was meant for me.

Yes, RICHARD it wasn't, it was for SUPERCODER2014. And as u said I posted on author's forum too, I think that might help

And my message was not directed at you, but SuperCoder2014.

Turbo C++ code. Copy paste this to a file named mouse.h . <-------- start of mouse.h

include
#include
#include
#include
#include

const ress=0xb;

unsigned hspd,vspd,thv,button,mouse_x,mouse_y;
int dirx,diry,dir_x,dir_y,trshold;
unsigned char mousestep;

void initmouse(void)
{
asm{
mov ax,1h
int 33h

 }

}

void hidemouse(void)
{
asm{
mov ax,2h
int 33h

 }

}

void getmousepos(void)
{
asm{
mov ax,3h
int 33h
mov button,bx
mov mouse_x,cx
mov mouse_y,dx
}
}

void getmousedirection(void)
{
asm{
mov ax,ress
int 33h
mov trshold,bx
mov dirx,cx
mov diry,dx
}
}

void getmousespeed(void)
{
asm{
mov ax,1bh
int 33h
mov bx,hspd
mov cx,vspd
mov dx,thv
}
}

<-------- end of mouse.h

[myth1990]

Thanks, I think it works, error relating to mouse.h is gone but not all so I will reply as soon as I debug it.

Hi, SuperCoder2014 your codes and links solve the problem about mouse handling during runtime but I stuck at deleting the bar3d(). At some point I have to create bar3d() using and after pressing mouse button I have to make disapper that bar3d() on the same background. Thanks for your help before, and I would appreciate any reply.
