    Smile Mouse ..Use in DOS

    #include <stdio.h>
    #include <conio.h>
    #include <graphics.h>
    void LoadMouse()
    {
    asm{
    mov ax,0x0000;
    int 0x33;

    }


    }
    void Beep()
    {
    asm{
    mov ax,0x0e07;
    xor bx,bx;

    int 0x10;

    }

    }
    void Show()
    {
    asm{
    mov ax,0x0001;
    int 0x33;
    }


    }
    void Hide()
    {
    asm{
    mov ax,0x0002;
    int 0x33;
    }


    }
    main()
    {
    int gD=DETECT,gM;
    initgraph(&gD,&gM,"C:\\TC\\BGI");
    LoadMouse();
    Show();
    getch();
    Hide();
    Beep();
    getch();
    Show();
    getch();
    }

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Thanks for the code Wunna. I'm sure that it's correct but when I try to compile it there is a linker error:

    "Undefined simbol _initgraph in module new.cpp"

    The file I'm writting is new.cpp in C:\Borlandc\Bin, the current directory.

    Of course I changed the call of the initgraph function in Wunna's code with initgraph(&gD,&gM,"C:\\BORLANDC\\BGI"); but the error still appears.

    What can I do?

    I still want a tutorial about mouse use in C++ (DOS mode)...

    Thanks.

    Do you link in graphics.lib? I dunno which version of Borland you're using, but older versions required that runtime library to be included. Check your project and check off that option.

    Use a dos based compiler for int 10h operations or you'll have problems with protection faults at runtime.
    I haven't used a compiler in ages, so please be gentle as I try to reacclimate myself. :P

    The functions available are
    mouse();
    initmouse();
    showmouseptr();
    getpoint();
    restrictmouseptr(int,int,int,int);
    getmousepos(int*,int*,int*);
    void setCursor(cursor_type cursor);
    void disableMouse();


    You can even set the cursor image like pointer, hand, hour glass etc...


    For this to work you have to run showmouseptr in a loop....
    like

    Code:
    int mian()
    {
    mouse m1;
    m1.initmouse();
    
    int x,y,button=0;
    while(button!=2)
    {
    showmouseptr();
    getmousepos(&button,&x,&y);
    }
    
    return 0;
    }

    Using the mouse in DOS is very easy. I had a thread on here at one time that showed about 9 sub-functions. I won't go into that many here but you really only need 5 functions. Here they are.


    struct Mousestruct
    {
    int x;
    int y;
    int button_down;
    }Mouse;


    void ResetMouse(void)
    {
    union REGS regs;
    regs.x.ax=0x0000;
    int86(0x33,&regs,&regs);
    }

    void ShowMouse(void)
    {
    union REGS regs;
    regs.x.ax=0x0001;
    int86(0x33,&regs,&regs);
    }

    void HideMouse(void)
    {
    union REGS regs;
    regs.x.ax=0x0002;
    int86(0x33,&regs,&regs);
    }

    void GetCoords(void)
    {
    union REGS regs;
    regs.x.ax=0x0003;
    int86(0x33,&regs,&regs);
    Mouse.x=regs.x.cx; //shift right by 1 if in 320x200 mode
    Mouse.y.=regs.x.dx;
    Mouse.button_down=regs.x.bx;
    }

    void PutMouse(int x,int y)
    {
    union REGS regs;
    regs.x.ax=0x0004;
    regs.x.cx=x;
    regs.x.dx=y;
    int86(0x33,&regs,&regs)
    }


    You can also do this in assembly but you probably won't gain any speed since this is a very simple task to perform. I have 2 libraries for the mouse - 1 in C and 1 in pure asm. If you are using assembly with C/C++ you must declare your functions like this.

    extern "C" void ResetMouse(void)


    For example let's call ResetMouse from C.

    In assembly:

    .model large
    .code

    public _ResetMouse

    ;No arguments so no need to push bp mov bp,sp ... pop bp
    _Reset Mouse proc
    mov ax,0000h
    int 33h
    ret
    _ResetMouse endp


    end


    In C:

    extern "C" void ResetMouse(void)

    int main(void)
    {
    ResetMouse();
    return 0;
    }



    Hope this helps. Some of the above posts looked a bit confusing - really all you need are the 5 functions that I provided you with.

    Reset mouse and driver - sub function 00h

    Show mouse cursor - sub function 01h

    Hide mouse cursor - sub function 02h

    Get mouse button data (also returns cursor info) - sub function 03h

    Position mouse cursor - sub function 04h
