前几天写了一篇键盘记录器,好多人反映看不懂,6 R4 O, J; d1 z& a
对新人没什么用处,所以且这篇我会写的- C4 }* G0 b. K9 h) z) Y6 U
很详细,再也不像那篇,出了代码什么也没 ^!^6 I5 h. [% C5 g! ^: g) g' Z8 R
这个程序将会详细的讲解如何记载键盘的每一次输入。
. A6 v3 J/ O9 c1 U0 m" b下面介绍的这个程序主要是利用GetAsyncKeyState函数,
, I: |. Q6 h& A. o使用GetAsyncKeyState可以获得键盘的动作。" f* L" w9 m d5 `4 V D/ N% ^9 }( z
GetAsyncKeyState函数根据虚拟键表判断按键的类型。
( ]* n1 s# _: v返回值为一个16位的二进值数,如果被按下则最高位为1,- Y, f+ p6 d: N& d
即返回-32767。下面是API函数及鼠标中左右键在虚拟键表中的定义:
* ~4 h( v4 w& HPrivate Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer. j2 c- c4 v2 {9 Y/ i
好了,函数就先介绍这么多,下面开始动手实战了
