You must call the CompleteWith() method during the Completion event 
handler to tell the autocompletion list associated with the specified text.

Public Sub MyTextBox_Completion(Text As String)

   Dim aList As New String[]

   ' Build the autocompletion list into 'aList', according to 'Text'.

   MyTextBox.CompleteWith(aList)

End

Whether there is a busy sign is decided inside the 'gb.web.gui' code for 
each event. I will add it for the Click event of menus.

Application_Error is available in any Gambas application, and so when 
you use 'gb.web.gui'.

But you can do inside is a bit difficult, as there is no way for the 
user to know the context (inside the request process, inside the session 
process, before the answer has been sent, in the middle of the request 
answer...)
