Auto-refresh an ASPX page

This is especially useful when using a master page but you don't want every page using the master page to refresh.

In the Page_Load() event handler, add this code:

'Refresh the page every 30 seconds.
Dim lit As New LiteralControl("<meta equiv=""refresh"" content=""30"" />")
Header.Controls.Add(lit)

Startup object must be a form when "Enable Application Framework" is checked.

If you're reusing a form and are trying to make it the main form of an application, and you get this error, ensure that the constructor for the form takes no arguments.
