主题：寻求注册表加密的例子

是这样吗？

Dim n As Integer = GetConfigValue("Count",1)
Dim Code As String = GetConfigValue("Register" & ComputerId,"")
Dim Ok As Boolean
If Code > "" AndAlso DecryptText(Code,"abc","abc") = ComputerId Then '如果注册码正确
    OK = True
Else
    If n > 30 Then
        Forms("注册").Open()
        Code = GetConfigValue("Register" & ComputerId,"")
        If Code > "" AndAlso DecryptText(Code,"abc","abc") = ComputerId Then '如果注册码正确
            OK = True
        End If
    End If
    If n > 60 AndAlso Ok = False Then
        Messagebox.Show("您正在使用的产品已经超出试用次数!")
        Syscmd.Project.Exit()
    End If
End If
n = n + 1
SaveConfigValue("HKEY_CURRENT_USER\Software\MyApp","Count",n)
