8.Explain Assemblies?,Difference between Panel and GroupBox?,Differences between ASP and ASP.NET?

A.ASSEMBLIES

Assemblies are the building blocks of .NET Framework applications; they form the fundamental unit of deployment, version control, reuse, activation scoping, and security permissions. An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. An assembly provides the common language runtime with the information it needs to be aware of type implementations. To the runtime, a type does not exist outside the context of an assembly.
I found that there are numerous posts for Assemblies but none for giving out the difference between Panel and a Group Box. Although a Panel as well as the groupbox are almost the same there are minute differences.

In group box you can enter text while you cant do that in Panel.

In Panel you have got a built in support for scrollbars which is not available in case of group box.

Hope this information is useful....Happy Programming !!!

A.Answer is yes. We can use http handlers to upload a file in asp.net.

To perform file upload in ASP.NET, you need to know two classes: the System.Web.UI.HtmlControls.HtmlInputFile class and the System.Web.HttpPostedFile. The first class represents an HTML control that the user uses to select a file on the client side and upload it. The latter represents the uploaded file itself, and an instance of this class is obtained from the HtmlInputFile control. The next two subsections discuss each class in detail.

<% @ Import Namespace="System.IO" %>
