What are the advantages of the code-behind feature?

Posted By :iswarya     Posted Date :October 18, 2013    Points :40   Category :ASP.Net 
The code-behind feature of ASP.NET offers a number of advantages:
. Makes code easy to understand and debug by separating application logic from HTML tags
. Provides the isolation of effort between graphic designers and software engineers
. Removes the problems of browser incompatibility by providing code files to exist on the Web server and supporting Web pages to be compiled on demand.

Advantages of the code-behind feature?

The code-behind feature of ASP.NET offers a number of advantages:

Makes code easy to understand and debug by separating application logic from HTML tags

Provides the isolation of effort between graphic designers and software engineers

Removes the problems of browser incompatibility by providing code files to exist on the Web server and supporting Web pages to be compiled on demand. (More...)

Describe the advantages of writing a managed code application instead of unmanaged one. What's involved in certain piece of code being managed?

"Advantage includes automatic garbage collection,memory management,security,type checking,versioning
Managed code is compiled for the .NET run-time environment. It runs in the Common Language Runtime (CLR), which is the heart of the .NET Framework. The CLR provides services such as security,
memory management, and cross-language integration. Managed applications written to take advantage of the features of the CLR perform more efficiently and safely, and take better advantage of developers existing expertise in languages that support the .NET Framework.
Unmanaged code includes all code written before the .NET Framework was introduced-this includes code written to use COM, native Win32, and Visual Basic 6. Because it does not run inside the .NET environment, unmanaged code cannot make use of any .NET managed facilities."

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.

Can code inside multiple catch block be executed?

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

Advantages of DBMS?

1.Redundancy is controlled.
2.Unauthorised access is restricted.
3.Providing multiple user interfaces.
4.Enforcing integrity constraints.
5.Providing backup and recovery. (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...)

Name a feature which is common to all .NET languages?

There is only one feature which is common to all languages and that is Garbage collection or GC. This feature is automated which relieves developers of much work. This garbage is disposed only when there is need of memory or stress for memory. GC feature halts the application for few seconds before restarting it. (More...)

What is a Managed Code?

Managed code runs inside the environment of CLR i.e. .NET runtime. In short all IL are managed code. But if you are using some third party software example VB6 or VC++ component they are unmanaged code as .NET runtime (CLR) does not have control over the source code execution of the language. (More...)

What is CODE Access security?

CAS is part of .NET security model that determines whether or not a piece of code is allowed to run and what resources it can use while running. Example CAS will allow an application to read but not to write and delete a file or a resource from a folder. (More...)

Advantages of Crystal Reports ?

Advantages of Crystal Reports :

Some of the major advantages of using Crystal Reports are:

1. Rapid report development since the designer interface would ease the coding work for the programmer.

2. Can extend it to complicated reports with interactive charts and enhance the understanding of the business model

3. Exposes a report object model, can interact with other controls on the ASP.NET Web form

4. Can programmatically export the reports into widely used formats like .pdf, .doc, .xls, .html and .rtf (More...)

What is CODE Access security?

Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions.

It performs following function
1. Defines permissions and permission sets that represent the right to access various system resources.
2. Enables administrators to configure security policy by associating sets of permissions with groups of code (code groups).
3. Enables code to request the permissions it requires in order to run, as well as the permissions that would be useful to have, and specifies which permissions the code must never have.
4. Grants permissions to each assembly that is loaded, based on the permissions requested by the code and on the operations permitted by security policy.
5. Enables code to demand that its callers have specific permissions.
6. Enables code to demand that its callers possess a digital signature, thus allowing only callers from a particular organization or site to call the protected code.
7. Enforces restrictions on code at run time by comparing the granted permissions of every caller on the call stack to the permissions that callers must have. (More...)

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...)
