— there are two slightly different goals here and each needs a different approach: showing a few setting values in a MessageBox (what pointed to), versus showing the actual app.config XML content. Concatenating short values into a MessageBox is fine for quick checks, but to display the raw XML you should load the config file, pretty-print it, then present that string.

A simple VB.NET way to load and pretty-print the current configuration file and show it in a MessageBox:

Dim cfgPath As String = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile
Dim doc As New System.Xml.XmlDocument()
doc.Load(cfgPath)

Dim sw As New System.IO.StringWriter()
Dim settings As New System.Xml.XmlWriterSettings()
settings.Indent = True

Using xw As System.Xml.XmlWriter = System.Xml.XmlWriter.Create(sw, settings)
    doc.WriteTo(xw)
    xw.Flush()
End Using

MessageBox.Show(sw.ToString(), "Configuration XML")

Notes and troubleshooting:

  • If your values are user-scoped settings they may be saved to a user.config under the user profile, not the exe config. Inspect the file path in cfgPath to be sure you’re viewing the file you expect.
  • MessageBox is poor for long XML (no scrolling or formatting control). For larger XML use a resizable Form with a multiline TextBox (ReadOnly) or export to a .xml file and open in an editor.
  • If a setting shows empty, verify the setting scope (Application vs User) and whether you’re reading the persisted value or defaults.
  • To read specific key/value pairs instead of the whole XML, use ConfigurationManager.AppSettings (add a reference to System.Configuration) or continue using My.Settings for strongly typed settings.

This keeps the raw XML intact and readable while avoiding the typical pitfalls of using MessageBox for large text.

If you have your info in textboxes then use:
Messagebox.Show(Textbox1.text & VbNewline & Textbox2.text & VbNewline & Textbox3.text & VbNewline & Textbox3.text)
