Name
StaticObjects
Synopsis
HttpStaticObjectsCollection = Session.StaticObjects
Returns an HttpStaticObjectsCollection containing all objects
instantiated in global.asax by using the
<object runat="server"> syntax whose scope
is set to Session.
Parameters

" objects declared with the " & _
"<object runat="server"> syntax in Session scope."
Dim myobj As Object
For Each myObj in Session.StaticObjects
If myObj.Value.GetType.ToString( ) = _
"System.Web.UI.WebControls.TextBox" Then
myForm.Controls.Add(myObj.Value)
End If
Next
