Google Analytics

What is Google Analytics?

Google Analytics is a analytic tool (Google :-)) for websites or blogs.

Analyses are e.g.:

• site views
• dwell time
• new users
• recurring users
• ...

Due to this values you can analyse your website or blog. 

To find out what went wrong or what can be done better you only have to ask you the question to the value:

• Why users are leaving the website very fast?

Is it the design? They found a solution (fast, maybe directly on the main page?)

With the values, the questions and the answers you can start to optimize your website or blog.

Your experience with Google Analytics?

C# - Impersonator

I think everybody was already at this point... A program should handle file transfers or modifications but the access to the target path is not given to everybody.
How to handle this situation? :-(

One answer could be, to use one common account (inside the program) to do these actions.

I have tried to solve this situation like following:


1) Create a new class "Impersonator"

using System;
using System.Security.Principal;
using System.Runtime.InteropServices;
using System.ComponentModel;

namespace Test.Impersonator
{
    public class Impersonator : IDisposable
    {
        public Impersonator(string userName, string domainName, string password)
        {
            ImpersonateValidUser(userName, domainName, password);
        }

        public void Dispose()
        {
            UndoImpersonation();
        }

        [DllImport("advapi32.dll", SetLastError = true)]
        private static extern int LogonUser(string lpszUserName, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);

        [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern int DuplicateToken(IntPtr hToken, int impersonationLevel, ref IntPtr hNewToken);

        [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern bool RevertToSelf();

        [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
        private static extern bool CloseHandle(IntPtr handle);

        private const int LOGON32_LOGON_INTERACTIVE = 2;
        private const int LOGON32_PROVIDER_DEFAULT = 0;

        private void ImpersonateValidUser(string userName, string domain, string password)
        {
            WindowsIdentity tempWindowsIdentity = null;
            IntPtr token = IntPtr.Zero;
            IntPtr tokenDuplicate = IntPtr.Zero;

            try
            {
                if (RevertToSelf())
                {
                    if (LogonUser(userName, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token) != 0)
                    {
                        if (DuplicateToken(token, 2, ref tokenDuplicate) != 0)
                        {
                            tempWindowsIdentity = new WindowsIdentity(tokenDuplicate);
                            impersonationContext = tempWindowsIdentity.Impersonate();
                        }
                        else
                        {
                            throw new Win32Exception(Marshal.GetLastWin32Error());
                        }
                    }
                    else
                    {
                        throw new Win32Exception(Marshal.GetLastWin32Error());
                    }
                }
                else
                {
                    throw new Win32Exception(Marshal.GetLastWin32Error());
                }
            }
            finally
            {
                if (token != IntPtr.Zero)
                {
                    CloseHandle(token);
                }
                if (tokenDuplicate != IntPtr.Zero)
                {
                    CloseHandle(tokenDuplicate);
                }
            }
        }

        private void UndoImpersonation()
        {
            if (impersonationContext != null)
            {
                impersonationContext.Undo();
            }
        }

        private WindowsImpersonationContext impersonationContext = null;
    }
}


2) Use the Impersonator class in you main program around the function which should run under a different user.

using...
using Test.Impersonator;
namespace Test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void StartDataTransfer()
        {
              //Do something as User1
            using (new Impersonator("UserName", "Domain", "Password"))
            {
                     //Do something as User2
            }
        }
    }
}
  


Feel free to ask/feedback :-)

C# - Simple List examples

What is a List?

A list is a collection of data.

Example

• Create a new list

//initialize an empty list for objects with type of INTEGER
List<int> numbers = new List<int>();

//initialize an empty list for objects with type of STRING
List<string> names = new List<string>();

//initialize a list with objects type of INTEGER
List<int> numbers = new List<int>() {1,2,3,4}; //List with 4 integer elements

//initialize a list with objects type of STRINGList<string> names = new List<string>() {"Dad","Mum","Child"}; //List with 3 string elements

• Add elements to a list

//add one element at the end 
numbers.Add(5);

//add a collection of new elements at the end
numbers.AddRange(new List<int>() { 6, 7, 8 });


//add one element at the end 
names.Add("Child2");

//add a collection of new elements at the end
names.AddRange(new List<string>() { "Child3", "Child4" });



//add one element at a defined position
numbers.Insert(8, 9);

//add one element at a defined position
names.Insert(6, "Child5");



//add a collection of new elements starting at a defined position
numbers.InsertRange(9, new List<int>() { 10, 11, 12 });

//add a collection of new elements starting at a defined position

names.InsertRange(7, new List<string>() { "Child6", "Child7" });

• Remove elements from a list

//remove the object with the value 8 from the list         
numbers.Remove(8);

//remove the opbject with the value Child from the list         
names.Remove("Child");

//remove object at position 3         
numbers.RemoveAt(3);

//remove 2 elements, starting at position 4         
numbers.RemoveRange(4, 2);
