Use HashSet class.

What type of code (server or client) is found in a Code-Behind class?

Server-side code since code-behind is executed on the server. However, during the code-behind's execution on the server, it can render client-side code such as JavaScript to be processed in the clients browser. But just to be clear, code-behind executes on the server, thus making it server-side code. (More...)

How to find data with generics list in VB.NET (Write code).

In the code example below, the function "FindData" will return list("sublist") of the objects having matchingKey same as viewstate value.
Dim sublist As List(Of MyClass)
sublist = allClient.FindAll(AddressOf FindData) 'sublist will contain objects matching specified matching condition

Function FindData(ByVal b As MyClass) _
As Boolean
If (b.matchingKey = CInt(ViewState("matchingKey "))) Then 'matching condition
Return True
Return False
End If
End Function (More...)

List or HashSet seems to be faster?

HashSet is than faster list? (More...)

Explain how managed code slower than unmanaged code?

Managed code not always is slower than unmanaged code. In managed code, the CLR does some optimization for the way loops, subroutines should run and what is the best way to execute it. (More...)

What is the managed and unmanaged code in .net?

The .NET Framework provides a run-time environment called the Common Language Runtime, which manages the execution of code and provides services that make the development process easier. Compilers and tools expose the runtime's functionality and enable you to write code that benefits from this managed execution environment. Code that you develop with a language compiler that targets the runtime is called managed code; it benefits from features such as cross-language integration, cross-language exception handling, enhanced security, versioning and deployment support, a simplified model for component interaction, and debugging and profiling services. (More...)

Can code inside multiple catch block be executed?

No, Code can not execute in mutiple catch block (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...)

What is managed code and managed data?

Managed code is code that is written to target the services of the Common Language Runtime (see What is the Common Language Runtime?). In order to target these services, the code must provide a minimum level of information (metadata) to the runtime. All C#, Visual Basic.NET, and _JScript.NET code is managed by default. Visual Studio.NET C++ code is not managed by default, but the compiler can produce managed code by specifying a command-line switch (/CLR).
Closely related to managed code is managed data-data that is allocated and de-allocated by the Common Language Runtime's garbage collector. C#, Visual Basic, and _JScript.NET data is managed by default. C# data can, however, be marked as unmanaged through the use of special keywords. Visual Studio.NET C++ data is unmanaged by default (even when using the /CLR switch), but when using Managed Extensions for C++, a class can be marked as managed by using the __gc keyword. As the name suggests, this means that the memory for instances of the class is managed by the garbage collector. In addition, the class becomes a full participating member of the .NET Framework community, with the benefits and restrictions that brings. An example of a benefit is proper interoperability with classes written in other languages (for example, a managed C++ class can inherit from a Visual Basic class). An example of a restriction is that a managed class can only inherit from one base class. (More...)

List out the areas in which data structures are applied extensively?

1.Compiler Design,
2.Operating System,
3.Database Management System,
4.Statistical analysis package,
5.Numerical Analysis,
7.Artificial Intelligence,
8.Simulation (More...)

If you are using C language to implement the heterogeneous linked list, what pointer type will you use?

The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type. (More...)

List the Coffman's conditions that lead to a deadlock.

1. Mutual Exclusion: Only one process may use a critical resource at a time.

2. Hold & Wait: A process may be allocated some resources while waiting for others.

3. No Pre-emption: No resource can be forcible removed from a process holding it.

4. Circular Wait: A closed chain of processes exist such that each process holds at least one resource needed by another process in the chain. (More...)

Difference between imperative and interrogative code.

There are imperative and interrogative functions and I think they are talking about that. Imperative functions are the one which return a
value while the interrogative functions do not return a value. (More...)
