4、最后将项目的AfterOpenProject事件设为:
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("Count",n)
问题:下面"abc","abc"是可以,是否有长度要求,是只有三个字符?最长多少字节?是否只能写字母,还是可以字母大小写和数字,中文一起混合?
If Code > "" AndAlso DecryptText(Code,"abc","abc") = ComputerId Then '如果注册码正确
If Code > "" AndAlso DecryptText(Code,"abc","abc") = ComputerId Then '如果注册码正确
