代码如下:
(对其他键都有效,但按下SHIFT等键程序无反应!)
怎么回事? 用中断函数也这样.是不是 CONFIG.SYS中要什么配置?


#include <stdio.h>
#include <bios.h>
#include <ctype.h>
main()
{
int key1=0,key2=0;

while(!bioskey(1));
key1=bioskey(0);
key2=bioskey(2);

printf("%X,%X\n",key1,key2);

}

//不能用bioskey()读到，可从bois数据区中获得！

//WinSail V2.0有一个函数AfxKeyboardState，其代码是这样的


#define KEYBOARD_STATE_RSHIFT 0
#define KEYBOARD_STATE_LSHIFT 1
#define KEYBOARD_STATE_CTRL 2
#define KEYBOARD_STATE_ALT 3
#define KEYBOARD_STATE_SCROLLLOCK 4
#define KEYBOARD_STATE_NUMLOCK 5
#define KEYBOARD_STATE_CAPSLOCK 6
#define KEYBOARD_STATE_INSERT 7

//函数名称:AfxKeyboardState
//函数功能：
//入口参数：int nState --- 要判断的按键
= KEYBOARD_STATE_RSHIFT 右"Shift"键
= KEYBOARD_STATE_LSHIFT 左"Shift"键
= KEYBOARD_STATE_CTRL "Ctrl"键
= KEYBOARD_STATE_ALT "Alt"键
= KEYBOARD_STATE_SCROLLLOCK "ScrollLock键"
= KEYBOARD_STATE_NUMLOCK "NumLock键"
= KEYBOARD_STATE_CAPSLOCK "CapsLock键"
= KEYBOARD_STATE_INSERT "Insert键"

//出口参数：无
//返 回 值：与按键匹配时返回TRUE，否则返回FALSE
BOOL far AfxKeyboardState(int nState)
{
BYTE far *pHead = (BYTE far *)0x00400017L;


return (((*pHead) & (1 << nState)) ? TRUE : FALSE);
}



//举例
int main()
{
//只要按下"Shift"，则退出
while (!AfxKeyboardState (KEYBOARD_STATE_LSHIFT) &&
!AfxKeyboardState (KEYBOARD_STATE_RSHIFT))
{
}
return (0);
}

可惜你这个不能在 TC/BC里用的...
