Reply from XXX.XXX.XXX.XXX: bytes=32 time=564ms TTL=237
Reply from XXX.XXX.XXX.XXX: bytes=32 time=555ms TTL=237
Reply from XXX.XXX.XXX.XXX: bytes=32 time=554ms TTL=237
Reply from XXX.XXX.XXX.XXX: bytes=32 time=548ms TTL=237


Ping statistics for XXX.XXX.XXX.XXX:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)

Approximate round trip times in milli-seconds:

Minimum = 548ms, Maximum = 564ms, Average = 555ms

TTL?

Every IP packet that gets sent out has a TTL field which is set to a relatively high number (in the case of ping a TTL of 255). As the packet traverses the network, the TTL field gets decreased by one by each router it goes through; when the TTL drops to 0, the packet is discarded by the router. The IP spec says that the TTL should be set to 60 (though it's 255 for ping packets). The main purpose of this is so that a packet doesn't live forever on the network and will eventually die when it is deemed "lost." But for ping purposes, it provides additional information. The TTL can be used to determine approximately how many router hops the packet has gone through. If the TTL field varies in successive pings, it could indicate that the successive reply packets are going via different routes, which isn't a great thing.




'ping time'?
"Ping time" refers to the amount of time it takes for a small "packet" of data to travel over the internet from one computer to another computer and back to the first computer. It is usually reported in milliseconds (ms).

Creating Dynamic Menu Bar C#.Net

Here is the example for the Dynamic Menu creation..
U need to create css for the static and dynamic styles,
Important thing is the menu id , Menu ID should be minimum (maintain around 10 charaters) , I spent lot of time to identify the Issue which created by menu id , I was given over 30+ character which makes effect on total Controls which is available on the page..

private Panel CreateDynamicMenuBar(List<string> Permissions, string GroupName)
    {
        Menu MyMenu = new Menu();
        MyMenu.ID = "menu";
        MyMenu.Orientation = Orientation.Vertical;
        MyMenu.StaticDisplayLevels = 1;
        MyMenu.Width = Unit.Percentage(100);
        MyMenu.StaticMenuStyle.BorderWidth = Unit.Pixel(0);
        MyMenu.StaticMenuItemStyle.HorizontalPadding = Unit.Pixel(0);
        MyMenu.CssClass = "treemenustyle2";
        MyMenu.StaticMenuItemStyle.CssClass = "StaticItem1";
        MyMenu.StaticHoverStyle.CssClass = "StaticHighlight1";
        MyMenu.DynamicMenuStyle.CssClass = "ie8fix";
        MyMenu.DynamicMenuItemStyle.CssClass = "DynamicItem1";
        MyMenu.DynamicHoverStyle.CssClass = "DynamicHighlight1";
        MyMenu.DynamicSelectedStyle.CssClass = "DyanamicSelected1";
        MyMenu.StaticSelectedStyle.CssClass = "StaticSelected1";
        MyMenu.MenuItemClick += new MenuEventHandler(this.Menutasks_SelectedItemChanged);
        MyMenu.Items.Clear();
   
        foreach (var v in Permissions)
        {
            string permissions = v;
            MenuItem item = null;
            item = new MenuItem( permissions );
            item.ToolTip = permissions[1];
            MyMenu.Items.Add(item);
        }
     
        Panel menupannel = new Panel();
        menupannel.Controls.Add(MyMenu);
        return menupannel;
    }

Response.Redirect vs Server.Transfer

Server.Transfer does a server side transfer.

Response.Redirect does a client side redirect - the server informs thebrowser to redirect.
So here's the flow:

Server.Transfer
1. Client Request Page HelloWorld.ASPX2. Server.Transfer -> Server send a different page to the client3. Client Receives Page still thinking it's HelloWorld.ASPX.4. Client's URL (Address bar) remains HelloWorld.ASPX since the page wassent on the server side and the client doesn't know a different page wassent.

Response.Redirect
1. Client Requests Page HelloWorld.ASPX2. Response.Redirect -> Server sends a HTTP header informing that theuser should redirect. 3. Client sees the redirect notice and requestsAnotherPage.ASPX 4. Server sends AnotherPage.ASPX5. Client's URL (address bar) shows AnotherPage.ASPX
Technically speaking, Server.Trasfer is faster since there 1 lessroundtrip, but you lose the URL of the page. Server.Transfer also allowsfor more flexibilty since you can use HTTPContext.Items to passvariables beteen pages

.cs files got corrupted?

If your .cs file got currupted then we have one chance to recover those files.

You need to have the assembly dll related to that currupted file which was build previously.
you need to do Disassembler using .Net Reflector


Solution to recover .cs file 
1. Just Download the .Net Reflector and Install. http://www.reflector.net/
2. Open File -> ' Export Assembly source code'

3. In that Export dialogue show the dll related to corrupted file by 'Browse' option and Click 'Start'

Show any other related dll's if required while processing.

Your files will be Generated in the specified 'Output Directory'

IComparer interface
public class AlphanumComparatorFast : IComparer

 if (s1 == null)

     string str1 = new string(space1);

     int result;

     if (char.IsDigit(space1[0]) && char.IsDigit(space2[0]))

This type of issues will get if u connecting to database using Windows Authentication mode you have to give permission individually if u install SQL server in Windows Authentication mode.

If u install  SQL server in window authentication by default If you do not choose mixed authentication at the time of SQL Server installation. However these modes can be changed even after installation of SQL Server.
