Master Pages in ASP.NET "Whidbey"

Just casually browsing through ASP.NET website and I was reading some content on Whidbey, the next version of Visual Studio .NET and ASP.NET. Web Application development in Classic ASP used include files to define common layouts and templates.

Moving a step towards ASP.NET, we had Register TagPrefix Templates and Web User Controls to achieve the same. Or we could also define a common BasePage, which defines the layout shared for the entire application, giving a placeholder to the actual control at Runtime. But then, the BasePage concept lacked support in Visual Studio .NET Designer.

Coming up next, in ASP.NET next version, is Master Pages, which defines a page designed as a Base Layout master, with an extension .master, that dictates the overall layout of the page itself.

Other pages use the Page Directive and link to this Master page via a Master attribute of the Page directive. Sections marked with <asp:ContentPlaceHolder> in Master Page are overridden in the child Web Pages.

A nice feature that I think many web developers would love to work with. I did a simple Google Search on ASP.NET Master Pages Support and perhaps a significant number of following URLs that could help you out in knowing more about Master Pages are the following:
I hope it would be useful for a lot of ASP.NET developers worldwide.

Google NCR

Google NCRMost of you would be knowing about this trick in navigating to Google generic website. But I just came to know only a few days before and hence thought I would share the information with others too.
Whenever you type http://www.google.com/, Google automatically tries to redirect you to your country-specific website. For me, it always redirects to http://www.google.co.in/ (Google India). But when we specifically want to navigate to Google Generic website for some reason, there are two ways to accomplish the same.Click the 'Go to Google.com' link at the bottom of the webpage that is displayed from http://www.google.co.in/To prevent this redundant click, you can opt to type http://www.google.com/ncr/ which would prevent the redirect from happening. The NCR stands for No Country Redirect. There is a brief discussion about this NCR over this forum.You may also like to check out Google help documentation regarding the country redirections from here.

Elegant 'MailTo' Replacement

Elegant 'MailTo' Replacement

MailTo tags have become a bane to all websites since spammers run spam robots which crawl the web to capture the email addresses, add to their catalogs and send spams to them. I just thought of sharing with others a simple JavaScript function which would trigger open the default email client instead of having mailto: embedded in the HTML Page.

Just have the following function included in your webpage

<script language='Javascript'>
function WriteMailTo(user,domain)
{
location.replace ('mailto:'+user+'@'+domain);
}
</script>

And whereever you want to invoke the mailto, just called WriteMailTo('user','example.com') and the user's default email client should be launching (if configured) without any hassles.

Contacts import utility from Web2Project to Addressbook

I have been using Web2Project for planning my personal and professional tasks for a few years now. Now I have bifurcated the tools into the following:

Project PierAddress Book The only issue I had was to import my addressbook from Web2Project to AB. PP is a different animal. It does not serve as a comprehensive candidate for addressbook and hence I needed this bifurcation. 
I wrote up a following simple script to import the contacts to AB. The pre-requisite for this script is to hop on to PhpMyAdmin, export the contacts as a PHP array and then  modify the path in our import script to whatever you downloaded from PhpMyAdmin.
Our import script would explode the entries as SQL scripts into the browser window. Copy them and execute into PhpMyAdmin AB database to have the contacts imported.
