Access asp.net session value in javascript

var Guest = '<%=HttpContext.Current.Session["Advisorguest"]%>';

Common Logic For Getting Single Value From Database Asp.Net

1) string[,] param1 = new string[1, 2];
param1[0, 0] = "@userName";
param1[0, 1] = username;

2) string status = CommonClass.Common.Instance.getSingleValue("checkIsExistUserName", param1);

3) SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["ValweaveFa"].ConnectionString);
SqlCommand sm;
public string getSingleValue(string procNm, string[,] paramVal)
{
try
{
myConnection.Open();
sm = new SqlCommand(procNm, myConnection);
sm.CommandType = CommandType.StoredProcedure;

for (int i = 0; i < paramVal.Length / 2; i++)
{
if ((paramVal[i, 0] != null) && (paramVal[i, 1] != null))
sm.Parameters.Add(paramVal[i, 0], paramVal[i, 1]);
}
string Password = Convert.ToString(sm.ExecuteScalar());
myConnection.Close();
return Password;

}
catch (Exception ex)
{
throw ex;
}

Managed Extensibility Framework

Managed Extensibility Framework:

Three core concepts with MEF:

1) Export(s) : It exposes Contracts and contract like .NET Interface or Class or property

Code:

[Export(typeof(ICache))]

Public class Caching: ICache

{

Public object Get(string cache_key)

{

//Caching implementation

}

2) Imports: Used to consume exported instances.

Code:

[Import()]

Private ICache cache;

3) Catalog: hosts components that need to be composed.

Code:

Public static void Compose(object o)

{

var container = new CompositionContainer(

new DirectoryCatalog(Path.Combine(

AppDomain.CurrentDomain.BaseDirectory,

@”bin\MEFBin”)));

Var batch = new CompostionBatch();

batch.AddPart(o);

container.Compose(batch);

}

Application Design - Layered Architecture

Layered Architecture:

1) Presentation Layer - User Interface of application

2) Business Logic Layer – Rules of application

3) Data Access Layer – Responsible for connecting to data source and interacting with data that is stored in that location.

e.g. database, some XML files, text files or web service.

4) Utility /Components Layer – Mechanism of caching, logging errors, reading from configuration files.

Create independent project called Component layer

a) Presentation layer – Web

b) Business layer – entities, business logic, components, interfaces

c) Data Layer – Entities, Data Access

d) Components Layer – Caching, logging, Configuration
