.Net is less a programming language and more of a framework for developing applications. Any language that can be build to target the CLR (Common Language Runtime) can be considered a "dot net" language. Examples include C#, VB.Net, IronRuby, IronPython, and F#. One of the more popular languages, C#, was heavily influenced by Microsoft's Anders Hejlsberg, who was one of the original inventors of the Borland language Delphi.

Different set of attributes which are able to identify any row in the database is known as super key. And minimal super key is termed as candidate key i.e. among set of super keys one with minimum number of attributes. Primary key could be any key which is able to identify a specific row in database in a unique manner.

The Dakota Sandstone is a sedimentary rock formation that was deposited during the Cretaceous period, approximately 100 million years ago. The water necessary for the deposition of the sand grains in the Dakota Sandstone would have come from a variety of sources, including rivers, lakes, and coastal environments that existed in the region during that time.

I am writing a barcode scanner system.

First, I print barcodes like QR Code and Data Matrix on paper. Then scan these barcodes with a hardware barcode scanner. This scanner must read the barcode and verify its validity. Some organizers may want to verify ticket validity offline or online..

Some questions:

-Do I need a windows based app (so do something with windows forms?)?

- the scanned data from the scanner is sent to a PC...can I with VB.NET receive that data and pass it to an online app/server to verify the validity realtime?

- any other things I should consider?

Basically I want to avoid installing client software, is it possible?

Dim aInt as Integer = 5

Dim aStr As String = String.Empty

aStr = System.Convert.ToString(aInt)

User-centered design (UCD) is an approach to design that focuses on understanding the needs and goals of the users and creating solutions that meet those needs. Three characteristics of user-centered design are:

Empathy: User-centered design requires designers to empathize with the users to understand their needs, goals, motivations, and challenges. Designers must put themselves in the shoes of the users and see the world from their perspective.

Iteration: User-centered design is an iterative process that involves prototyping, testing, and refining the design based on feedback from the users. Designers must be willing to iterate and make changes to the design based on user feedback.

Usability: User-centered design focuses on creating products that are easy to use and efficient. The design should be intuitive, with clear and concise instructions, and should minimize the cognitive load on the user. Designers must consider the user's physical, cognitive, and emotional abilities when creating the design.

Overall, user-centered design places the user at the center of the design process and prioritizes their needs and goals over other factors. By focusing on empathy, iteration, and usability, designers can create products that are more effective, efficient, and satisfying for the users.

I want to get the content of div with its class with VB.Net but i don't know how to do it. i show you a simple example to notice what my question is.

<div class="whatever">Text</div>

I opened a website and I found above code in its source code. and i want the content of this div code for my text box or label ...

yes,it is platform independent because it uses CLR(common language runtime) for compiling the codes and then the code can be run on any platform.

Create a new form and put a textbox in it. Et voila.

You can add extra things like change font, size, word wrap, find/replace, print etc.. but bear in mind that you cannot change colour in a textbox. Well, you can but if you want to save it - you need to save it as a .RTF document so it saves the styles (bold, italic, colour etc.) - so i would use a richtextbox instead of a textbox.

Dim x(1)

x(0) = 5

x(1) = 2

Dim NewArray(1)

For xx = 0 To x.Length -1

Dim item As Integer

item=xx-x.Length -1

item=item * -1

NewArray(xx) = x(item)

Next

Their you go at first the original array was 5,2

after you run the loop it will be 2,5.

In Check box, you can select multiple options. In Option Button (also known as Radio button), you can select only one option at a time.

A Check box is rather similar to an option button. The Value property of both the controls is tested to check the current state. Check boxes are valid as a single control whereas a single option button is probably counts- intuitive.Check boxes are not mutually exclusive.

dim obj as object

obj = new object();

Some disadvantages of VB.NET is that it is mainly only used for software development. As an electrical engineer me and my teem often use VB.NET to make a business applications. If you want to develop games you should not spend your time learning VB.NET, instead you should spend your time learning C++ or C#.
