我試圖實現鼠標interfecing,但有些輸入函數錯誤。它應該告訴我,wheater我做了左鍵單擊或右鍵單擊,但它不打印任何東西。看看:鼠標沒有輸入
#include<graphics.h>
#include<dos.h>
union REGS in,out;
void Graphics(void);
void DetectMouse(void);
void ShowMouse(void);
void HideMouse(void);
void InputMouse(void);
int main()
{
Graphics();
DetectMouse();
ShowMouse();
// HideMouse();
InputMouse();
getch();
closegraph();
return 0;
}
void Graphics(void)
{
int driver=DETECT,mode;
initgraph(&driver,&mode,"C:\\TC\\bgi");
outtextxy(1,1,"Graphics mode activated!");
}
void DetectMouse(void)
{
int result;
in.x.ax=0;
result=int86(0x33,&in,&out);
if(result)
{
outtextxy(10,10,"Driver succesfully detected");
}
else
{
outtextxy(10,10,"Driver not detected");
}
}
void ShowMouse(void)
{
in.x.ax=1;
int86(0x33,&in,&out);
}

int86(0x33,&in,&out);
if(out.x.bx==1)
outtextxy(30,30,"Left click");
