View 2 RepliesI am having a problem with security in a web application I am building using Visual Web Developer 2008. I am using Forms Authentication:
<authentication mode="Forms">
<forms name=".MYAUTH" timeout="20" enableCrossAppRedirects="true" />
</authentication>
And a SQL Server database with ASP.NET Membership and Roles. I am using the LoginView control with the AnonymousTemplate and LoggedInTemplate to manage the user's interaction with logging in and out. The problem I am having is that I am authenticating the user against the database:
If Membership.ValidateUser(_userName, _txtLoginPass.Text)
Then returns True and:
FormsAuthentication.SetAuthCookie(_userName, False)
sets the cookie correctly:
FormsAuthentication.Decrypt(FormsAuthentication.GetAuthCookie(_userName, False).Values(0))
{System.Web.Security.FormsAuthenticationTicket} CookiePath: "/"

Resetting IDENTITY column to a new valueDuring application development we always entry some test data also our tester test with test data and as a result if the table contains IDENTITY columns( specially ID column) which incremented to the number of data already entered.
However, when the application goes running with real data to the client and the client want his ID values from starting 1, then we need to RESEED the value of the IDENTITY column of the table after clearing all data. This can be done as bellows:
DBCC CHECKIDENT (TableName, RESEED, 0)
However, can be reseed with any values instead of zero(0) in the above statement.
I have an identity column that increment by 1 on every insert. I have deleted all the rows using delete query but the identity coulumn is still not reseting to zero, how do i reset it, as it was when the table was first created.
