如何在 VB .NET 应用程序中保存应用程序设置？

Question

I made a projet a month ago in C# where I used application settings to save data. This time, I'm making a project in VB .NET where I need to store data. I have a textbox where the user input a certain key and if he gets it right, it sets a setting to true. Here's the code.

 Public Class Form4
  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
      If TextBox1.Text = ("CF4A438C1F68D" Or "7552B2C629D11" Or "9C9C94A73141A" Or "7EE3998DAB3D3" Or "FC4DABC9CA7EA" Or "FDEE4B1F2C113" Or "D773E97B47531" Or "AABBBF181D39A" Or "36F37B39D19A5") Then
          Properties.Settings.Default.ActivatedVersion = True
          Properties.Settings.Default.Save()
      End If
  End Sub
End Class

Unfortunately, when I write Properties, it doesn't work. How can I do this?

In VB, you use My.Settings rather than Properties.Settings.Default .

Also, you don't necessarily need to call Save explicitly as it will happen automatically, by default, when the application exits. It won't happen if the application crashes but, if you have done the right thing and handled the UnhandledException event, the application will not crash, even if an unhandled exception is thrown.
