Module 1: Introduction to Visual Studio 2010 and C#
                                    This is a comprehensive introduction to the Microsoft Visual Studio programming environment and Microsoft .NET. Learn how to create a project, what is .NET, how to get started with C#, and runtime debugging. The hands-on lab helps you get experience building applications in Visual Studio 2010. It walks you through the steps required to create a console application, interfaces and types that implement those interfaces in C#, a library to hold common (shared) code, and a simple Windows Presentation Foundation (WPF) application by using the shared library.

Module 2: Introduction to the Microsoft Biology Foundation
                          This module provides an overview of the Microsoft Biology Foundation (MBF), its scenarios, architecture, and a starter project. It also provides an introduction to the source code and unit tests required for contributing back to the open-source project. The hands-on lab helps you get experience working with sequences, parsers, formatters, and the transcription algorithm that is supplied in MBF. It walks you through the steps required to build a simple Windows Forms application that can load a set of sequences from a file, transcribe them, and then write those sequences to the same or a different file.

Module 3: Working with Sequences
                         This module examines the Sequence data type in MBF. Learn how to load sequences into memory and save them, the different sequence types available, how to use sequence metadata, and how data virtualization support enables support for large data sets. The hands-on lab familiarizes you with managing sequences and sequence items by using MBF interfaces, properties, and methods to create a WPF application to visualize the data.

Module 4: Parsers and Formatters
                          This module explores MBF’s built-in sequence parsers, formatters, alphabets, and encoders. It also introduces the method of expanding MBF with custom alphabets, parsers, and formatters. The hands-on lab walks you through the steps that are required to build a simple custom parser and formatter for a fabricated biology data format, and then plug it into MBF and the sequence viewer/editor that were created in Module 3.

Module 5: Algorithms
                       This module examines the algorithms defined in MBF for sequence alignment, multi-sequence alignment, sequence fragment assembly, transcription, translation, and pattern matching against sequences, and explains how to create custom algorithms. The hands-on lab walks you through the steps required to build an application to run algorithms against sequences loaded with MBF and perform sequence alignment, assembly, and transformations.

Module 6: Web Services
                  This module introduces Microsoft .NET web services, the web service architecture in MBF, the built-in web service support in MBF for BLAST (Basic Local Alignment Search Tool), and ClustalW; how to call these services asynchronously; and presents a detailed example of how to build custom service wrappers. The hands-on lab walks you through the steps of building an application that executes the BLAST algorithm by using web services against sequences loaded with MBF. You get some experience loading and identifying web service handlers for BLAST, passing sequences and sequence fragments to BLAST, changing the BLAST parameters, and displaying the results from a BLAST run.

Bill Gates Vs Paul Allen

Microsoft co founder Paul Allen has spoken of his partner trying to dilute his stake in the global company before he left in a new memoir he has written.


Paul Allen reveals the plotting in exerts of his book which have been publish in the Vanity Fait magazine.


He claims in the memoir that he had overheard conversations between Bill Gates and Steve Ballmer, who is now the Chief Executive of the company, back in 1982 when he had said that he was thinking of leaving the company.


Allen writes: “It was easy to get the gist of the conversation. They were bemoaning my recent lack of production and discussing how they might dilute my Microsoft equity by issuing options to themselves and other shareholders. It was clear that they'd been thinking about this for some time.”


While Paul Allen added that he has received apologies from both Bill Gates and Steve Ballmer regarding the entire incident however he has come forward to let the world know about the insides of the Microsoft corporation in this new book.


He added: “As it turned out, Bill's conservatism worked to my advantage. If he'd been willing to offer something close to my asking price, I would have sold way too soon.”


Bill Gates has responded to the accusations in an emailed statement saying: “While my recollection of many of these events may differ from Paul's, I value his friendship and the important contributions he made to he world of technology and at Microsoft.”


Although Paul Allen may have had problems with Microsoft his holdings in the company have been responsible for making him the 57th richest person in the world according to Forbes Magazine, with a fortune of $13 billion.


The full account from Paul Allen is available in his book, Idea Man, which is set to be published at the end of the month.

Google delays open-source Android 3.0

Google is holding onto its tablet OS a bit longer, delaying its open-source release until it works on smartphones too.
                                
                                    Dubbed Honeycomb, Android 3.0 was unveiled earlier this year. It's the first Google mobile OS to be designed specifically for tablets, and will first show up on the Motorola Xoom.
In the past, Google has allowed open-source developers access to the Android OS, raising concerns the company doesn't intend to open up the tablet version.
                                        A Google spokesperson said Honeycomb was delayed because it wasn't ready to be customised for use on smartphones, but would eventually be released to the open-source world.
"While we're excited to offer these new features to Android tablets, we have more work to do before we can deliver them to other device types including phones," a Google spokeswoman said.
"We're committed to providing Android as an open platform across many device types and will publish the source as soon as it's ready," the spokesperson said, adding there was no timeline for when it would happen.

OOPS

Class:
Class is concrete representation of an entity. It represents a group of objects, which posses similar attributes and behavior. Provides Abstraction and Encapsulations. A category name that can be given to group of objects of similar kind.


Object:
Object represents/resembles a Physical/real entity. An object is simply something you can give a name.


Object Oriented Programming:
is a Style of programming that represents a program as a system of objects and enables code-reuse.


Encapsulation:
Binding of attributes and behaviors. Hiding the implementation and exposing the functionality.


Abstraction:
Hiding the complexity. Defining communication interface for the functionality and hiding rest of the things.
In .Net destructor can not be abstract. Can define Either Finalize / Destructor. For Destructor access specifiers can not be assigned. It is Private.


Overloading:
Adding a new method with the same name in same/derived class but with different number/types of parameters. Implements Polymorphism.


Overriding:
When we need to provide different implementation than the provide by base class, We define the same method with same signatures in the derived class. Method must be Protected/Protected-Friend/Public for this purpose. (Base class routine can be called by Mybase.Method, base.Method)


Shadowing:
When the method is defined as Final/sealed in base class and not overridable and we need to provide different implementation for the same. We define method with Shadows/new.


Inheritance:
Gives you ability to provide is-a relationship. Acquires attributes and behaviors from another. When a class acquires attributes and behaviors from another class. (must not be Final or sealed class in .Net)


Abstract Class:
Instance can not be created. Optionally can have one or more abstract methods but not necessary. Can provide body to Classes.


Interface:
What a Class must do, But not how-to.
Bridge for the communication when the caller does not know to whom he is calling.
Describes externally visible behavior of element.
Only Public members which defines the means of the communication with the outer world. Can-be-Used-As Relationship.Can not contain data but can declare property. There can be no implementation. Interface can be derived from another interface.


Polymorphism:
Mean by more than one form. Ability to provide different implementation based on different no./type of parameters.
A method behaves differently based on the different input parameters. Does not depend on the Return-Type.


Pure-Polymorphism:
Make an method abstract/virtual in base class. Override it in Derived Class. Declare a variable of type base class and assign an object of derived class to it. Now call the virtual/abstract method. The actual method to be called is decided at runtime.


Early-Binding:
Calling an non-virtual method decides the method to call at compile time is known as Early-Binding.


Late-Binding:
Same as pure-polymorphism.


Identifiers/Access Specifies and scope:
Private, Protected, Friend, Protected Friend, Public
private, protected, internal, protected internal, public


What is a Delegate?
A strongly typed function pointer. A delegate object encapsulates a reference to a method. When actual function needs to be called will be decided at run-time.


Static Variable and Its Life-Time:
Public Shared VAR As Type Or public static Type VAR;
Life time is till the class is in memory.


Constructor:
Special Method Always called whenever an instance of the class is created.


Destructor/Finalize:
Called by GC just before object is being reclaimed by GC.

Indian Rupee Symbol

Today the Windows team released an update which adds support for the new rupee currency symbol for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. You can find more information about the update at KB2496898.

What Does This Update Mean for Office Users?

This update will allow users to input, view, print, and use the new symbol as the default symbol for data formatted as Indian currency, such as in Access fields, Excel cells, or the currency column in SharePoint lists.

The Windows update touches three main areas that will help Office users.

1. Updates the following font families: Microsoft Sans Serif, Times New Roman, Arial, Segoe, and Tahoma.

2. Updates the 13 Indic local keyboards to input the rupee using the Ctrl+Shift+4. On the new English (India) keyboard, the AltGr+4 key combination will input the new symbol. More on adding or changing your input language.

3. Updates the locale information so that the new symbol is automatically used for items formatted as currency, such as in Access fields, Excel cells, or the currency column in SharePoint lists. More on changing the country or region settings.

Typing the Rupee Symbol

If you don’t have a keyboard that supports the rupee symbol, you can insert the rupee currency symbol by using one of the following methods.

Using Alt-X

Type 20B9, and then hold down the ALT key and press X. (Supported by OneNote, and Outlook WordMail, and Word.)

Important: Some of the Microsoft Office programs, such as PowerPoint and InfoPath, cannot convert Unicode codes to characters. If you need a Unicode character and are using one of the programs that doesn't support Unicode characters, use the Character Map to enter the character(s) that you need.

Insert Symbol

Supported by Excel, InfoPath, OneNote, Outlook WordMail, PowerPoint, Publisher, SharePoint Designer, and Word

Insert a symbol

1. Click where you want to insert the symbol.

2. On the Insert tab, in the Symbols group, click Symbol.

3. Do one of the following:

· Click the symbol that you want in the drop-down list.

· If the symbol that you want to insert is not in the list, click More Symbols. In the Font box, click the font that you want, click the symbol that you want to insert, and then click Insert.

· Note If you are using an expanded font, such as Arial or Times New Roman, the Subset list appears. Use this list to choose from an extended list of language characters, including Greek and Russian (Cyrillic), if available.

4. Click Close.

Using Character Map

Character Map is a program built into Microsoft Windows that enables you to view the characters that are available in a selected font. Using Character Map, you can copy individual characters or a group of characters to the Clipboard and paste them into any program that can display them.

For more information about the Character Map, see Using special characters (Character Map): frequently asked questions.

Click Start, point to All Programs, point to Accessories, point to System Tools, and then clickCharacter Map.

To select a character in the Character Map, click the character, click Select, click the right mouse button in your document where you want the character, and then click Paste.

Printing the Rupee Currency Symbol

If your printer does not have the rupee currency symbol in any of its resident fonts, a box will be printed instead of the rupee currency symbol. Contact your printer vendor to find out how to get updated printer fonts that include the rupee currency symbol. You can also adjust your printer setup not to use resident fonts. Look for an option called Print fonts as graphics in printer setup properties.

Known Issues

Font Fall Back

If you are using a font that doesn’t contain the new symbol, then your application may not be able to render the character. The work around is to change the font for that one character. We are aware of the issue and are working on a fix.

SharePoint 2007

The Windows update does not fix .NET 3.5 in some scenarios and therefore SharePoint 2007 currency fields will not default to the new symbol. We are working to address this issue.

Office 2010 Web App

Due to a known browser limitation, users will not be able to type the new rupee symbol in Internet Explorer when font is not specified (for example, in the address bar or Web App Find text box).

Microsoft Security Essentials is a free* download from Microsoft that is simple to install, easy to use, and always kept up to date so you can be assured your PC is protected by the latest technology. It’s easy to tell if your PC is secure — when you’re green, you’re good. It’s that simple.

                          
Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want—without interruptions or long computer wait times.


Minimum system requirements for Microsoft Security Essentials


Operating System: Genuine Windows XP Service Pack 3 (SP3); Windows Vista (Gold, Service Pack 1, or Service Pack 2); Windows 7


For Windows XP, a PC with a CPU clock speed of 500 MHz or higher, and 256 MB RAM or higher.
For Windows Vista and Windows 7, a PC with a CPU clock speed of 1.0 GHz or higher, and 1 GB RAM or higher.
VGA display of 800 × 600 or higher.
200 MB of available hard disk space.
An Internet connection is required for installation and to download the latest virus and spyware definitions for Microsoft Security Essentials.
Internet Browser:
Windows Internet Explorer 6.0 or later.
Mozilla Firefox 2.0 or later.
Microsoft Security Essentials also supports Windows XP Mode in Windows 7. For more information, see the system requirements for Windows XP Mode in Windows 7


This version of Microsoft® Security Essentials includes the following new features and enhancements to better help protect your computer from threats:


Windows Firewall integration. Security Essentials setup enables you to turn on or off Windows Firewall.


Network Inspection System. This feature enhances real-time protection by inspecting network traffic to help proactively block exploitation of known network-based vulnerabilities.


New and improved protection engine. The updated engine offers enhanced detection and cleanup capabilities with better performance.


These features are described in more detail in the following sections.


Windows Firewall integration


Windows Firewall can help prevent attackers or malicious software from gaining access to your computer through the Internet or a network. Now when you install Security Essentials, the installation wizard verifies that Windows Firewall is turned on. If you have intentionally turned off Windows Firewall, you can avoid turning it on by clearing a check box. You can change your Windows Firewall settings at any time via the System and Security settings in Control Panel.


Network Inspection System


Attackers are increasingly carrying out network-based attacks against exposed vulnerabilities before software vendors can develop and distribute security updates. Studies of vulnerabilities show that it can take a month or longer from the time of an initial attack report before a suitable security update is developed, tested, and released. This gap in protection leaves many computers vulnerable to attacks and exploitation for a substantial period of time. Network Inspection System works with real-time protection to better protect you against network-based attacks by greatly reducing the timespan between vulnerability disclosures and update deployment from weeks to a few hours.


Award-winning protection engine


Under the hood of Security Essentials is its award-winning protection engine that is updated regularly. The engine is backed by a team of antimalware researchers from the Microsoft Malware Protection Center, providing responses to the latest malware threats 24 hours a day.


Microsoft Security Essentials works automatically with Microsoft Update to ensure that your virus and spyware definitions are kept up to date.

Symptoms


This article addresses common issues with automatic updates, including the following situations:


You see error messages indicating that updates have failed.


When you check for updates, you receive an error message that the virus and spyware definition updates cannot be checked, downloaded, or installed.


Even though you are connected to the Internet, the updates fail.


Updates are not automatically installing as scheduled.


Cause


The most common causes for update issues are problems with Internet connectivity. For help with Internet connectivity, see I can't connect to the Internet issue (General topic). However, if you know you are connected to the Internet because you can browse to other Web sites, the issue might be caused by conflicts with your settings in Windows Internet Explorer.


Solution


Important:
