求帮忙写一个VB程序

两种方法  位运算  和 纯粹字符串处理

Private Sub Command1_Click()

'EnCode1 位运算实现加密

Dim arr() As Byte

Dim i As Integer

arr = StrConv(Text1.Text, vbFromUnicode)

For i = 0 To UBound(arr)

EnCode1 arr(i)

Next

Text2.Text = StrConv(arr, vbUnicode)

End Sub

Sub EnCode1(x As Byte) 'vb 默认byref 传地址

Dim h As Byte

Dim l As Byte

h = x And &HF0   'x字节高四渗敬胡位放入变量h, h低四位置零

x = Not x       'x按位取反

x = x And &HF   '高四位置零,保留取反后的低四位

x = x * &H2     '乘2左移1位 （第0~第6位移到第1~第7位丛拦,最高位丢弃）

l = x And &H10  '取出第4位

x = x And &HF   'x高四位置零

l = l / &HF     '第4位移到第0位

x = x Or l      '第四位拼到x上完成低4位的移位

x = x Or h      '高低4位拼在一起稿答,byref形参返回

End Sub

Private Sub Command2_Click()

'EnCode2 纯字符串处理实现

Dim s As String

Dim n As Integer

Dim i As Integer

s = ""

n = Len(Text1.Text)

For i = 1 To n

s = s &EnCode2(Mid(Text1.Text, i, 1))

Next

Text3.Text = s

End Sub

Function EnCode2(x As String) As String

Dim a As Integer

Dim s As String

a = Asc(x)

s = dec2binstr(a)

Dim sarr(1 To 9) As String

Dim i As Integer

For i = 1 To 8

sarr(i) = Mid(s, i, 1)

Next

For i = 5 To 8

If sarr(i) = "1" Then

sarr(i) = "0"

Else

sarr(i) = "1"

End If

Next

sarr(9) = sarr(4)

For i = 5 To 8

sarr(i - 1) = sarr(i)

Next

sarr(8) = sarr(4)

sarr(4) = sarr(9)

s = ""

For i = 1 To 8

s = s &sarr(i)

Next

a = binstr2dec(s)

EnCode2 = Chr(a)

End Function

Function dec2binstr(d As Integer) As String

Dim s As String

Dim a As Integer

Dim b As Integer

a = d

s = ""

Do

b = a Mod 2

a = a \ 2

If b >0 Then

s = "1" &s

Else

s = "0" &s

End If

Loop While a >= 1

a = Len(s)

If a <8 Then

s = String(8 - a, "0") &s

End If

dec2binstr = s

End Function

Function binstr2dec(s As String) As Integer

Dim x As Integer

x = &H0

For i = 1 To 8

x = x * &H2 + AscB(Mid(s, i, 1)) - AscB("0")

Next

binstr2dec = x

End Function

我想你先的做点音频文件，以供vb调用，（可以用“方正畅听”，它可以将文本转化为音频）桥中辩，然后用控件数组的方法来编程，并调用音频文件（可以将音频文件放在资源文件里）。

一个简单的例子：

添加26个按扭，name属性均为“zimu”，index为0~25

添加1个按扭，

name属性为caps

，caption为caps

lock

添加1个计时器，name属性为timer1，interval=10

代码如下（在这就不写其他按键和声音的代码了！只写了caps和a~z这27个键敏缺的）
