Introduction Oracle VM VirtualBox is an x86 virtualization software package, created by software company Innotek GmbH, purchased by Sun Microsystems, and now developed by Oracle Corporation as part of its family of virtualization products. Oracle VM VirtualBox is installed on an existing host operating system as an application; this host application allows additional guest operating systems, each known as a Guest OS, to be loaded and run, each with its own virtual environment. Supported host operating systems include Linux, Mac OS X, Windows XP, Windows Vista, Windows 7, Solaris, and OpenSolaris; there is also a port to FreeBSD. Supported guest operating systems include versions and derivations of Windows, Linux, BSD, OS/2, Solaris and others. Since release 3.2.0, VirtualBox also allows limited virtualization of Mac OS X guests on Apple hardware. Download VirualBox At very first, you need to download VirtualBox software and install it on your existing OS. Download it

Possible Solution Open command prompt and type ping google.com If you can’t able to ping then these steps will help you. This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 OR 208.67.220.220. 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is

Introduction We can see there are two or more ways to achieve the same results in LINQ that is by using dot notation and query expression. Look at the sample examples. Query Expression Example var results = from product in products                 orderby product.Price descending                 select new                 {                     product.Name,                     product.Price                 };   int count = 0; // print out the names foreach ( var p in results) {     Console .WriteLine( "Item: {0}, Cost: {1}" , p.Name, p.Price);     if (++count == 3)     {         break ;     }

Introduction LINQ (Language INtegrated Query) fills the gap between programming languages and database. According to Anders Hejlsberg (C# Chief Architect):- “Microsoft’s original motivation behind LINQ was to address the impedance mismatch between programming languages and database.” If we compare LINQ to SQL, LINQ is simpler, tidier and very handy to use. It’s rather like comparing C# to C/C++ Programming, the time is gone when C/C++ was best but now coder needs something special like LINQ and it’s a big win. SQL is a very old language that was invented about 1974. Since then it's been extended endlessly, but never redesigned. This has made the language messy. You might have become so accustomed to this that you can't see anything wrong. I think my above lines will increase your concrete knowledge a

Introduction Visual Basic provides variety of options when it comes to accessing the data stored in the database. Find all options below. (i) Data Access Objects (DAO) It communicates with the Microsoft access and other ODBC compliant data sources through the JET engine. (ii) ODBC Direct  It allows accessing ODBC data sources through the RDO (Remote Data Objects) and DAO objects bypassing the JET database engine. (iii) Data Control It binds data-aware controls to Microsoft access or other ODBC data sources. (iv) Remote Data Objects (RDO) It provides a frame work for using code to create and manipulate components of a remote ODBC database system. (v) Remote Database Control It binds to controls to an ODBC remote database. etc.

Introduction Recordset is logical set of records where Microsoft defines a record as 'A set of related data about a person, place, event or some other item'. Table data is stored in records (rows) in the database. Each record is composed of a set of related fields (columns) - each field defining one attribute of information for the record. Taken together, a record defines one specific unit of retrievable information in a database. There are five types of Recordset: (i) Table-type Recordset Basically it is a complete table from a database. We can use to add, change or delete records. This is the simplest in concept since it matches a complete table in the database, but is not necessarily the best choice in many applications. (ii) Dynaset-type Recordset The result of a query that can have updatable records, we can use to add, change or delete records. It can contain fields from one or more tables in a database and it provides worse performance than a ta

Open the notepad and type following vbscript codes:- *************************************************** Set wshShell =wscript.CreateObject("WScript.Shell") do wscript.sleep 100 wshshell.sendkeys "{CAPSLOCK}" wshshell.sendkeys "{NUMLOCK}" wshshell.sendkeys "{SCROLLLOCK}" loop *************************************************** Now, save this notepad file by name 'disco.vbs' and open that saved file to look disco lightings. Now, to stop this you need to open Task Manager and stop the process named 'wscript'.

Don't be cocky Confidence-i.e., appearing composed and sure of yourself as opposed to like a nervous wreck-is always an appealing quality..... Say the magic words Of course you don't want a potential boss to think you're gunning for the role of office kiss-ass, but playing it too cool can wreck your chances..... Don't sound rehearsed Most of us have gotten this well-meaning advice from a career counsellor: when you're asked "What's your biggest weakness? ..... Don't fail the question test There are only a few minutes left in the interview, and you get what seems like a throw-away: "Do you have any questions for me? ..... Detailed Post
