Who is Accessing Your System ?

This is quite interesting to know that who is accessing your shared folder in network. We can easily get the information of that user and even you can track what is the activity he is doing in your system. We can achieve this using WMI (Windows Management Instrumentation) and MQL ( Management Query Language ) .

For using WMI you need to add one DLL called System.Management.dll and add the namespace as

using System.Management

Now Read the current Session of your system.

private  void Read_Current_Session()
        {
           try
            {
                ManagementObjectSearcher searcher =
                   new ManagementObjectSearcher("root\\CIMV2",
                   "SELECT * FROM Win32_ServerConnection");
                foreach (ManagementObject queryObj in searcher.Get())
                {
                   String RemoteIPAddress = queryObj["ComputerName"].ToString();
                   String RemoteUserName = queryObj["UserName"].ToString();
                   String  RemoteActiveTime = queryObj["ActiveTime"].ToString();
                }
            }
            catch (ManagementException e)
            {
               MessageBox.Show("WMI Error: " + e.Message);
            }
        }

Few Years back I have developed one Open Source Tool (NetSpY) based on WMI and MQL. NetSpy (NetWorkSpy) is an Small Windows based application which will continiouly monitor your shared folder in the network and will generate the complete log of the accessing user activities. This can show you the immidiate popup message that who is accessing right now.

Beginners Guide’s to ASP.NET MVC Framework – Part 1 of n


This article describes overview of ASP.NET MVC Framework , MVC Control Flow etc.

This article is the Part 1 of the ASP.NET MVC Framework series.  In this article I have describes very basic over view of MVC Framework and the control flow of MVC. I will write a few articles in this series which will help all the beginners to move ahead. This article is only about what MVC is.

Overview

The Model-View-Controller (MVC) design pattern is an architectural design patterns for any standard development that separates the components of an application. This allows application to handle very flexible and extensible and easy to handle. ASP.NET MVC Framework is also one of the standard web development frameworks which separate the components of web development application different components.

ASP.NET MVC Framework having three main components

  1. Model
  2. View
  3. Controller

4

Model: The model manages the behavior and data of the application domain, responds to requests for information about its state from the view, and responds to instructions to change state (usually from the controller).

View: This represent the presentation layer of the web application. The view manages the display of information based on the data of model that is requested by controller.

Controller: Controller handles the user interaction with the web application.  User request comes through controller to model and manipulate the records from it and then render the data using View to UI.

Below diagram showing the overview of these three components

1

Request Flow for ASP.NET MVC Framework

  1. Request comes from User to Controller
  2. Controller processes request and forms a data Model
  3. Model is passed to View
  4. View transforms Model into appropriate output format
  5. Response is rendered to Browser

2

Above picture showing you the actual flow of ASP.NET MVP Framework.  Request comes from client to Controller and controller decided which model to used and based on that data rendered into browser.

Now, just have a closer look into to the MVC Flow,

3

In the next article I will give the explanation of each of every step. You just need to remember these are the basic flow of an MVC Application.

ASP.NET Web Forms and  MVC

MVC is not a replacement if ASP.NET Web Form based development. This seats on the top of ASP.NET Development.  MVC Framework simply divides the overall application architecture into three components.

For More information on the basic of MVC Framework please read :
ASP.NET MVC Overview (C#)

Summary

This is the startup article for MVC beginners. Many more to come. Where I will explain details of each of them with sample application. Finally there would be a complete ASP.NET project on MVC Framework. Hope this series will be helpful for all.

Using Bookmark in Visual Studio

Introduction

As name suggests, bookmarking speedup your code navigation in visual studio. There may be some portion of code where we need to move very frequently. Generally we scroll the page and move to that section, but Visual studio provides great features by which we can move to a particular section very quickly using some shortcut keys. This is called Bookmarking of Code.
Below are the set of Icons which are used to navigate the code using Bookmark.

BookMark1

How To Use

We can place the bookmark by clicking on Bookmark icon or using keys Ctrl + K, Ctrl + K. Below is the sample code where I have putted two bookmarks in different section of code.

BookMark2

Now we can easily navigate among those breakpoint using Ctrl + K, Ctrl + N for Next Bookmark and Ctrl + K , Ctrl + p for Previous mark. We can achieve the same using following toolbar icon.

BookMark3

This is very much easy to use and its give you very fast navigation throughout the code.

Using Bookmark Window:

Visual Studio provides you Bookmark window where you can get list of all bookmarked section.

BookMark4

Now, by selecting particular bookmark from the Bookmarks list we can easily move to the particular section.

BookMark5

Renaming BookMarks

For easy reference we can also rename bookmark so that we can easily identify them. This helps us to easily move to particular code block based on the name given.  This is useful when we are having many bookmarks in the bookmark list.

BookMark6

As I have renamed my bookmark list as below

BookMark7

Summary

This may not be new to many of us, but it may helpful for some beginners.  Using this features we can navingate our code very easily. Please provide your valuable suggestion and feedback.
