ValidatePasswordEventArgs.ValidatePasswordEventArgs Constructor

Creates a new instance of the ValidatePasswordEventArgs class.

Namespace: System.Web.Security
Assembly: System.Web (in system.web.dll)

'Declaration
Public Sub New ( _
	userName As String, _
	password As String, _
	isNewUser As Boolean _
)
'Usage
Dim userName As String
Dim password As String
Dim isNewUser As Boolean

Dim instance As New ValidatePasswordEventArgs(userName, password, isNewUser)
public ValidatePasswordEventArgs (
	String userName, 
	String password, 
	boolean isNewUser
)
public function ValidatePasswordEventArgs (
	userName : String, 
	password : String, 
	isNewUser : boolean
)
Not applicable.

Parameters

userName

The membership user name for the current create-user, change-password, or reset-password action.

password

The new password for the specified membership user.

isNewUser

true if the event is occurring while a new user is being created; otherwise, false.

The ValidatePasswordEventArgs constructor is used by a membership provider implementation in the CreateUser, ChangePassword, and ResetPassword method implementations.

The following code example shows a sample ChangePassword implementation that creates a new ValidatePasswordEventArgs object to pass to the ValidatingPassword event.

Public Overrides Function ChangePassword(username As String, _
                                         oldPwd As String, _
                                         newPwd As String) As Boolean
  
  If Not ValidateUser(username, oldPwd) Then
    Return False
  End If

  Dim args As ValidatePasswordEventArgs = _
    New ValidatePasswordEventArgs(username, newPwd, True)

  OnValidatingPassword(args)
  
  If args.Cancel Then
    If Not args.FailureInformation Is Nothing Then
      Throw args.FailureInformation
    Else
      Throw New MembershipPasswordException("Change password canceled due to New password validation failure.")
    End If
  End If


  Dim conn As OdbcConnection = New OdbcConnection(ConnectionString)
            Dim cmd As OdbcCommand = New OdbcCommand("UPDATE Users " & _
                       " SET Password = ?, LastPasswordChangedDate = ? " & _
                       " WHERE Username = ? AND Password = ? AND ApplicationName = ?", conn)

  cmd.Parameters.Add("@Password", OdbcType.VarChar, 128).Value = EncodePassword(newPwd)
  cmd.Parameters.Add("@LastPasswordChangedDate", OdbcType.DateTime).Value = DateTime.Now
  cmd.Parameters.Add("@Username", OdbcType.VarChar, 255).Value = username
  cmd.Parameters.Add("@OldPassword", OdbcType.VarChar, 128).Value = oldPwd
  cmd.Parameters.Add("@ApplicationName", OdbcType.VarChar, 255).Value = ApplicationName


  Dim rowsAffected As Integer = 0

  Try
    conn.Open()

    rowsAffected = cmd.ExecuteNonQuery()
  Catch e As OdbcException
    ' Handle exception.
  Finally
    conn.Close()
  End Try

  If rowsAffected > 0 Then Return True

  Return False
End Function
