This of course cam at the price of memory allocations. In .NET we can now take advantage of Static Variables, which in most cases can be faster than accessing the Application object.In .NET, most objects are actually classes, and Global.asax is no exception. To take advantage of this, we first have to give our Global.asax a Classname. We do this by adding the directive naming mine 'MyGlobals':
<%@ Application Classname="MyGlobals" %>
Then, we specify our Static Variable inside the script tags, using the 'Public' and 'Shared' keywords in the Global.asax:
VB
:
<Script language="vb" runat="server">
Public Shared sGreeting as String = "Visit HarrisonLogic.com!"
</Script>
C#
<Script language="C#" runat="server">
Public Static String sGreeting = "Visit HarrisonLogic.com!"
</Script>
Now that we have the variable 'sGreeting' set up, we can call it directly from our .aspx page using the Classname and the Variable name:
x
= MyGlobals.sGreeting
Give it a shot! The source code is below:[bold]Page1.aspx[/bold]
<% @Page Language="VB" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<script Language='vb' runat=server>
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text = MyGlobals.sGreeting
End Sub
</script>
</HEAD>
<body>
<asp:label runat=server id=Label1></asp:label>
</body>
</HTML>
[bold]Global.asax[/bold]
<%@ Application Classname="MyGlobals" %>
<Script language="vb" runat="server">
Public Shared sGreeting as String = "Visit HarrisonLogic.com!"
</Script>
