公共舱Form1
Dim MyPath As String =enteringcratchpin.aspx.vb
Private Sub Button1_Click（ByVal sender As System。 Object，ByVal e As System.EventArgs）处理Button1.Click
Dim Rdr作为新的StreamReader（MyPath）
Dim ln As String
Dim NewFile作为新的StringBuilder
ln = Rdr.ReadLine
直到没有任何东西
如果ln.StartsWith（Panel1.Visible = False）则ln =Panel1.Visible = True
NewFile.AppendLine（ln）
ln = Rdr.ReadLine
循环
Rdr.Close（）
文件。 WriteAllText（MyPath，NewFile.ToString）
End Sub
End Class

下面是我的enterscratchpin.aspx.vb，我想修改
保护小组的Page_Load（BYVAL发件人为对象，ByVal e As System.EventArgs）处理Me.Load
'我希望行panel1.value改为True
Panel1.Visible = False
结束Sub

推荐答案
哇。
这是写入的页面吗？这是一件疯狂的事情。我愿意打赌这是一个权限问题，也就是说，系统可以让你自己保存。而不是编写这种疯狂，编写基于配置值或内存中的值设置可见性的代码，或者有意义且可维护的内容。如何在代码自行更改的系统中维护代码？
Wow.
Is this the page being written to ? This is an insane thing to do. I am willing to bet that this is a permissions issue, also known as, the system saving you from yourself. Instead of writing this sort of insanity, write code that sets the visiblity based on a config value, or a value in memory, or something that makes sense, and is maintainable. How is anyone supposed to maintain code in a system where the code changes itself ?
