Accessing Web.Config AppSettings Collection Value

Web.config Settings:

** replace ( to < ** replace ) to >

(appSettings)
(add key="ContentFrameHeight" value ="600px"/)
(add key="ContentFrameWidth" value="700px"/)
(add key="MenuFrameHeight" value="400px"/)
(add key="MenuFrameWidth" value="250px" /)
(/appSettings)


Usually AppSettings placement:
configuration
configSections
"AppSettings"
system.web


Before using System.Configuration.Manager
We might need to add .NET reference, because by default this reference might not be added.
1. Right click "Add reference" > Add the System.Configuration as below figure.



Then you can apply the syntax below:


E.g syntax:
Dim height As String = ConfigurationManager.AppSettings("ContentFrameHeight").ToString

Accesing Master Page With IFRAME Property From Code Behind

Sometimes we need to access code front controls property from code behind, so that we can create a dynamic or configuration variable for this purpose.

How we know what property we have in the code front controls?
In the code front, we can get intellisense helps to verify whether it is a syntax or property with different colors.

ASP.NET Code Front:

(asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="Server")
(iframe id="mainContent" name="mainContent" src="../Dev.aspx" width="700px"
scrolling="auto" frameborder="0" marginheight="0" marginwidth="0" runat="server"
title="E-Application Content")(/iframe)
(/asp:Content)

** replace ( to < ** replace ) to >


ASP.NET Code Behind:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
mainContent.Attributes.Add("Height", "700px")
End Sub


Explanation:
IFRAME ASP.net Code behind having an "Attribute" syntax where we can simply accessing the value of controls in front page. Yet, code front control needed to be "runat=server" mode.

We created a master page, within the master page we have content place holder setup.
Then we create a new page and inherits master page layout.

In this case, we might still need to use traditional html href link to open a page onto a target.
We can use IFRAME with the id and NAME ( name is needed here ) and shown the page on the IFRAME.

With the code above, we can manipulate IFRAME property during page load.

"I first visited your blog, but my antispyware said that he is infected with an unknown virus.
I deleted the virus through this AntiSpyWare.
The virus does not manifest itself but gradually destroys information on the computer."

You probably have to be extra careful of those HiJacker

HOW THEY HIJACK YOUR PC?
If you are not careful enough, you probably will follow the link as what they leave at the forum, blogs, website or even through instant messenger.

It will brings you to a new page where it requests your authorization or permission to let hacker hijacks your local machine.

Here is the XPANTIVIRUS .com screen shot.
It prompts you to make a virus scan on your machine.

3. Wow, it able to SERVE you and PROTECT you for all aspect (virusese, spyware, adware ) !!

Redirection 301 Moved Permanently

Wow... nearly one month din't update my blog. Due to busy on Chinese New Year 2008 celebration and outstation for business trip.

Today's tip, to create a SEO friendly redirection method:

Search engines have indexed your entire site and many pages rank well. By moving and renaming these files, you run the risk of losing a lot of traffic and leaving visitors to your site who follow a search engine link with the dreaded "Error 404 - File not found"


There are several way recommended:
1. 301 Redirection
The code "301" is interpreted as "moved permanently". After the code, the URL of the missing or renamed page is noted, followed by a space, then followed by the new location or file nam




2. Meta Refresh / Redirect
This method always used by spammer to redirect their page to itself, so that they can get the counts. This is so called illegal traffic. Thus, use this method wisely.

The code will be located in the header tag.
