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); } [ Last edited by GOTOmsdos on 2007-3-3 at 11:46 AM ]

//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); } [ Last edited by firstsail on 2007-3-4 at 12:41 AM ]

可惜你这个不能在 TC/BC里用的...
