还是不对   加密出来还是只加密最后一位数

1、 ch = Mid(str1, i, 1) ch为字符型
2、 Select Case ch
   Case 0 为数值型
3、 如果内容为123
  Select Case ch
  Case "0"
  Case "1"
  Case "2"
  或者
  Select Case val(ch)
  Case 0
  case 1
4、如果内容为字符p，q
  case "p"对应处理就行
 case "q"
 你的程序select case 根本就没执行到内部，ch只是最后取得字符

Private Sub Command2_Click()
  Dim str1 As String
  Dim str2 As String
 dim temp as string
  Dim i As Integer
  dim ch(9) As String
  ch(0)="n",ch(1)="p",ch(2)= "m",ch(3)"x",ch(4)="b",ch(5)="c",ch(6)="d",ch(7)="ne",ch(8)="f",ch(9)="g"
  str1 = Text1.Text
  For i = 1 To Len(str1)
   temp = Mid(str1, i, 1)
      str2=str2&ch(val(temp))
    Next i
   Text2.Text = str2
End Sub

''''str2=“n”，每次判断后重新赋值，之前的判断结果没有保存，所以结果只能保存最后一位
'''赋值语句改为str2=str2&“n”，噢啦，妥妥滴，

知识有限，仅供参考，希望对你有帮助

Private Sub Command1_Click()
  Dim Strx As String, chx As String, I As Integer, CH
  CH = Array("n", "p", "m", "x", "b", "t", "s", "g", "e", "w")   '修改了二个字符 l-t 7-s
  For I = 1 To Len(Text1.Text)
   chx = Mid(Text1.Text, I, 1)
      Strx = Strx & CH(Val(chx))
    Next I
   Text2.Text = Strx
End Sub

上面程序使用数组存储转换字符，然后取出数字，以数字对应数组的值转换为字符

非常感谢  我试过了  很完美  

您好，怎样再反转换回来呢，就是再把字母转换成数字，谢谢您！

同样的数组，
遍历数组
判断相符，取其索引
字符链接


标准的数组查询
