CompareValidator control.

Can you control concatenation of string values with null values?

  
Concatenation of string values with null values results either null value or string value.
We can control that by setting CONCAT_NULL_YIELDS_NULL on or off.
When it is set to ON, the concatenation will result null and when it is set to OFF, it will result the string.
Setting it ON,
SET CONCAT_NULL_YIELDS_NULL on;
print 'testing' + NULL; --results NULL and prints nothing

Setting it OFF,

SET CONCAT_NULL_YIELDS_NULL off;
print 'testing' + NULL; -- results testing and prints the same (More...)

What is serialization in .NET? What are the ways to control serialization?

  
Serialization is the process of converting an object into a stream of bytes. Deserialization is the opposite process of creating an object from a stream of bytes. Serialization/Deserialization is mostly used to transport objects (e.g. during remoting), or to persist objects (e.g. to a file or database).Serialization can be defined as the process of storing the state of an object to a storage medium. During this process, the public and private fields of the object and the name of the class, including the assembly containing the class, are converted to a stream of bytes, which is then written to a data stream. When the object is subsequently deserialized, an exact clone of the original object is created.
Binary serialization preserves type fidelity, which is useful for preserving the state of an object between different invocations of an application. For example, you can share an object between different applications by serializing it to the clipboard. You can serialize an object to a stream, disk, memory, over the network, and so forth. Remoting uses serialization to pass objects "by value" from one computer or application domain to another.
XML serialization serializes only public properties and fields and does not preserve type fidelity. This is useful when you want to provide or consume data without restricting the application that uses the data. Because XML is an open standard, it is an attractive choice for sharing data across the Web. SOAP is an open standard, which makes it an attractive choice.

There are two separate mechanisms provided by the .NET class library -
XmlSerializer and SoapFormatter/BinaryFormatter. Microsoft uses XmlSerializer for Web Services, and uses

SoapFormatter/BinaryFormatter for remoting. Both are available for use in your own code. (More...)

What are server controls?

  
ASP.NET server controls are components that run on the server and encapsulate user-interface and other related functionality. They are used in ASP.NET pages and in ASP.NET code-behind classes. (More...)

Does omitting the parenthesis make the syntax cleaner?

  
Yes, if "cleaner" to you is fewer characters on the screen. No, if "cleaner" to you is something that appeals to the sense of logic and reason. (More...)

Which control cannot be placed in MDI?

  
The controls that do not have events.
Another MDI Container. (More...)

Minimum number of queues needed to implement the priority queue?

  
Two. One queue is used for actual storing of data and another for storing priorities. (More...)

What is a user control?

  
An ASP.NET user control is a group of one or more server controls or static HTML elements that encapsulate a piece of functionality. A user control could simply be an extension of the functionality of an existing server control(s) (such as an image control that can be rotated or a calendar control that stores the date in a text box). Or, it could consist of several elements that work and interact together to get a job done (such as several controls grouped together that gather information about a user's previous work experience). (More...)

What is the difference between login controls and Forms authentication?

  
Login controls are an easy way to implement Forms authentication without having to write any code. For example, the Login control performs the same functions you would normally perform when using the FormsAuthentication class—prompt for user credentials, validate them, and issue the authentication ticket—but with all the functionality wrapped in a control that you can just drag from the Toolbox in Visual Studio. Under the covers, the login control uses the FormsAuthentication class (for example, to issue the authentication ticket) and ASP.NET membership (to validate the user credentials). Naturally, you can still use Forms authentication yourself, and applications you have that currently use it will continue to run. (More...)
