November 21st, 2008 admin If the collation property of a data base is
1.Latin1_General_BIN its case-sensitive
2.SQL_Latin1_General_CP1_CI_AS or Latin1_General_CI_AI its case-insensitive
There are two ways to find out the SQL Server Database Collation
1. Using DATABASEPROPERTYEX
DATABASEPROPERTYEX gets the current setting of the specified database option or property for the specified database.
SELECT DATABASEPROPERTYEX(‘testdb’, ‘Collation’)
This returns the testdb Database Collation property value say if this testdb is a case-sensitive database then it returns
Latin1_General_BIN
2.Using Sql Server Management Studio
Step 1 : Open Sql Server Management Studio.
Step 2 : Right Click on database and click its properties
After clicking the properties you get a database properties modal box such as
The red box shows the collation property value of that database.

November 14th, 2008 admin The if tag allows the conditional execution of its body according to the value of the test attribute
<c:if test=”${empty details.add}”>
It is a Empty ArrayList
</c:if>
The choose tag performs conditional block execution by the embedded when subtags. It renders the body of the first when tag whose test condition evaluates to true. If none of the test conditions of nested when tags evaluates to true, then the body of an otherwise tag is evaluated, if present.

November 14th, 2008 admin usually you would send a random generated password while user does the registration process through your application.You can use the following code to achieve that.
public string Generate_Password() { string Password = “”; byte Cnt, Idx; string values = “0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ”; Random rnd = new Random(); for (Cnt = 1; Cnt <= 6; Cnt++) { Idx = (byte)rnd.Next(0, values.Length); Password += values.Substring(Idx, 1); } return Password.Trim().ToUpper(); }
To Generate Random Password we have used the Random Class(Namespace:-System).To learn more about Random Class have a look at this MSDN LINK.

November 12th, 2008 admin A delegate is a type that references a method.Once a delegate is assigned a method, it behaves exactly like that method. The delegate method can be used like any other method,with parameters and a return value.
Any method that matches the delegate’s signature,which consists of the return type and parameters,can be assigned to the delegate.
Delegates allow methods to be passed as parameters.It can be used to define callback methods.

November 10th, 2008 admin ASP.NET view state is the technique used by an ASP.NET Web page to persist
changes to the state of a Web Form across postbacks.That is when a form is submitted in ASP .NET, the form reappears in the browser window together with all form values.
The ViewState indicates the status of the page when submitted to the server. The status is defined through a hidden field placed on each page with a <form runat=”server”> control.
Hidden field placed on each page would be something as this
< input type=”hidden” name=”__VIEWSTATE” value=”CEbzzzEnmmz+Bc8IDFlnpgCLJ/HB00.” >
Maintaining the ViewState is the default setting for ASP.NET Web Forms. If you want to NOT maintain the ViewState, include the directive l%@ Page EnableViewState=”false” %> at the top of an .aspx page or add the attribute EnableViewState=”false” to any control.
