Clear Browser History Through Javascript

If you need to clear the Browser History, after arriving on a particular page (e.g. arriving to Login page after Logout).

Here is the code to do this. If you put this code in Login page, it wont take it to be back page. You need to put this from where you do not want to move back. Here is the code snippet.

<script type="text/javascript">
        window.onload = function () { Clear(); }
        function Clear() {            
            var Backlen = history.length;
            if (Backlen > 0) history.go(-Backlen);
        }
</script>

if you do not want the user to move to the back page, you can do as below. This script needs to be repeated at where you don’t want to do this.

<script type="text/javascript">
       if(window.history.forward(1) != null)
           window.history.forward(1);
</script>

Hope this helps.

Utility : Dell Dock

I have been waiting for some thing like this from Microsoft for so long. I have seen this in Mac and Linux system. But Star dock has build it for Dell. The Dell Dock is a task-based organizer for Dell Laptops or Desktops. It is helpful to the users to sort their software applications into friendly categories, which can be accessed easily from a dock. So that the user can leave the desktop free of clutter. Dell Customers don't have to locate and open a program by application name by rather can locate it by task, like "email & chat", "security", "view photos", "play music", etc..

Here is the screen shot how it look like once you install it

Hope this is useful. I Love it Smile

How to: Serializable with DAAB

This is how we can convert as Serializable which are written in Data Layer with Enterprise Library DAAB. All you need to do is make the Class and Connection object as Serializable.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Text;
using System.Data;
using System.Data.Common;
using Microsoft.Practices.EnterpriseLibrary.Data;
using System.Runtime.Serialization;
/// <summary>
/// Summary description for DataLayer
/// </summary>
[Serializable]
public class DataLayer : IDeserializationCallback
{
    [NonSerialized]
    Database db;
    
	public DataLayer()
	{
        db = DatabaseFactory.CreateDatabase("DBConnectionString");        
	}
    public DataTable GetClients()
    {
        DataTable result = new DataTable();
        DbCommand dbcommand = db.GetStoredProcCommand("GetAll_Clients");
        DataSet ds = db.ExecuteDataSet(dbcommand);
        if (ds.Tables.Count > 0)
        {
            result = ds.Tables[0];
            ds = null;
        }
        return result;
    }
    #region IDeserializationCallback Members
    void IDeserializationCallback.OnDeserialization(object sender)
    {
        db = DatabaseFactory.CreateDatabase("DBConnectionString");
    }
    #endregion
}

But you need to make all the data layer classes serializble this way to get the connection right.

Windows Azure Services Platform

Windows Azure™ is a cloud services operating system that serves as the development, service hosting and service management environment for the Windows Azure platform. Windows Azure provides developers with on-demand compute and storage to host, scale, and manage web applications on the internet through Microsoft® datacenters.

Windows Azure is a flexible platform that supports multiple languages and integrates with your existing on-premises environment. To build applications and services on Windows Azure, developers can use their existing Microsoft Visual Studio® expertise. In addition, Windows Azure supports popular standards, protocols and languages including SOAP, REST, XML, Java, PHP and Ruby.

Application Scenarios:

Windows Azure is a service that allows developers to run applications and store data on servers owned and operated by Microsoft. These cloud applications can be targeted at businesses, consumers or both. Some examples are:

  • Enterprises that use Windows Azure to run their own line-of-business, batch processing or large-volume computations.
  • An independent software vendor (ISV) that creates a SaaS application targeted towards business users.
  • Perform large-volume storage, batch processing, intense or large-volume computations
  • An ISV that creates a SaaS application targeted towards consumers.

Benefits:

  • Agility: Take advantage of development tools, automated service management and global datacenter presence to respond faster to customer needs, focus on your competitive differentiators, and reach new markets.
  • Efficiency: Windows Azure improves productivity and increases operational efficiency by lowering up-front capital costs. Customers and partners can realize a reduction in Total Cost of Operations of some workloads by up to 30 – 40% over a 3 year period . The consumption based pricing, packages and discounts for partners lower the barrier to entry for cloud services adoption and ensure a predictable IT spend.
  • Focus: Focus on delivering services and value to your customers – and not on managing technology infrastructure. Windows Azure enables you to spend less time on operational hurdles and more time focusing on your competitive differentiators.
  • Simplicity: Utilize your existing skills in familiar languages such as .NET, Java and PHP to create and manage web applications and services.
  • Trustworthy: Enterprise class service backed by a reliable service level agreements and a rich online services experience.

Features:

Windows® Azure serves as the development, run-time, and control environment for the Windows Azure Platform. Windows Azure handles load balancing, resource management and life cycle management of a cloud service based on requirements that the owner of the service established. A developer who wishes to deploy an application to Windows Azure specifies the service topology, including the number of instances to deploy and any configuration settings. Windows Azure deploys the service and manages upgrades and failures to maintain availability.

Storage Services

The Windows Azure storage services provide persistent, durable storage in the cloud. The fundamental storage services include:

  • Binary Large Object (BLOB) service for storing text or binary data
  • Queue service, for reliable, persistent messaging between services
  • Table service, for structured storage that can be queried
  • Windows Azure Drive that allows Windows Azure applications to mount a Page Blob, which is a single volume NTFS VHD. This allows applications to upload/download VHDs via blobs.

The Windows Azure SDK offers a REST API and a managed API for working with the storage services. You may access the storage services from within a service running in Windows Azure or directly over the Internet from any application that can send and receive data over HTTP/HTTPS.

Happy Birthday, Firefox

Today marks the sixth birthday of the popular web browser Firefox. It was launched on November 9, 2004 as a lightweight and more secure alternative to Internet Explorer 6, which was the dominant browser at the time. Six years later, and Firefox is now the second most widely used browser with steady growth and 31.5% market share according to StatCounter. The next major version of Firefox, Firefox 4, was originally scheduled to be launched by the end of 2010 but was recently delayed into early 2011.

The new version will bring several important improvements like HTML5 support, redesigned user interface, multi-touch functionality, hardware-accelerated HD video and improved support for add-ons through Jetpack
