Creating User Services

  • The identity object of the IIdentity interface is used during the authentication process, when a user’s identity is verified. It contains information about a user who is being validated, such as username and password.
  • The principal object of the IPrincipal interface is used during the authentication process, when the application determines the data that can be accessed by a user and code to be executed. It contains information about a user’s identity, such as username and password, as well as information about a user’s role, such as manager or associate.
  • The correct sequence of the classes of the System.Windows.Forms namespace in descending order is as follows:
    1. Control
    2. ScrollableControl
    3. ContainerControl
    4. Forms
  • The MinimumSize property of the Form class is used to get or set the minimum size up to which a form can be resized.
  • Continue reading

Creating and Managing Microsoft Windows(r) Services, Serviced Components, .NET Remoting Objects, and XML Web Services

  • The SessionID property of the HttpSessionState class identifies an active ASP.NET session by using a unique session ID.
  • The Process.Start method is used to start a Windows application and is registered in the system registry on a computer.
  • The Status property of the ServiceController class specifies the status of the current instance of a Windows service.
  • If a class derives from the ServiceBase class, the OnCustomCommand method is executed when the Service Control Manager (SCM) passes a custom command to the service. This method is used to specify actions when a command with the specified parameter value occurs.
  • The AutoLog property of the ServiceBase class is used to determine whether or not a service automatically logs the entries in the event log when events such as Start, Stop, Pause, and Continue occur.
  • The CreateEventSource method of the EventLog class establishes an application as a valid event source for writing event information to a particular event log on a computer.
  • The Imports statement is used to import namespace names from referenced projects and assemblies.

e-business Infrastructure

  • File Transfer Protocol (FTP) is an Internet service that helps in transferring files from one computer to another over the Internet.
  • Layer 2 Tunneling Protocol (L2TP) is a more secure version of Point-to-Point Tunneling Protocol (PPTP). It provides tunneling, address assignment, and authentication.
  • Virtual private network (VPN) uses a tunneling protocol to span public networks, such as the Internet, without security risk. VPN enables remote users to access corporate networks securely by using a tunneling protocol such as PPTP or L2TP.
  • TCP/IP is the primary protocol of the Internet.
  • SMTP uses port 25 by default.
  • Address Resolution Protocol (ARP) is a network maintenance protocol of the TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC) addresses of a network interface card (NIC).
  • FTP uses port 20 and 21 by default.
  • MIME stands for Multipurpose Internet Mail Extensions. It is a standard for multi-part, multimedia electronic mail messages and World Wide Web hypertext documents on the Internet.
  • The TCP/IP protocol should be bound to the dial-up adapter for Internet access on a Windows 98 computer.

Oracle architecture

  • The size of the shared pool can be changed dynamically. The data dictionary cache of the shared pool holds the most recently accessed data dictionary information. The shared pool consists of a library cache and data dictionary cache.
  • Control file, redo log file, and data file are part of an Oracle database.
  • An SGA and Oracle background processes constitute an Oracle instance. An SGA is ended when an Oracle instance is shut down. Multiple users can share data in an SGA.
  • While making modifications in SPFILE, the instance should be in open and running state, whereas in the case of PFILE, the instance will have to be first shut down and restarted before making any modifications in it.
  • V is a dynamic performance view that is used to display the names and the location of all the control files.
  • Following is the correct sequence of the processes that occur when a database is opened:
    1. An initialization parameter file is read.
    2. Continue reading
