If you have a datagridview and want to be able to right-click, which should automatically selecte the row that you've clicked and fire the ContextMenuStrip, it can be done as follows:

private void dataGridView1_MouseClick(object sender, MouseEventArgs e)

{

    if (e.Button == MouseButtons.Right)

    {

        foreach (DataGridViewRow s in dataGridView1.SelectedRows)

            s.Selected = false;

        DataGridView.HitTestInfo hit = dataGridView1.HitTest(e.X, e.Y);

        dataGridView1.Rows[hit.RowIndex].Selected = true;

        dataGridView1.CurrentCell= dataGridView1.Rows[hit.RowIndex].Cells[hit.ColumnIndex];

        contextMenuStrip1.Show(dataGridView1, new Point(e.X,e.Y) );

    }

}

 In web.config:

<appSettings>
    <add key="ContactUsEmail" value="me@mysite.com"/>
</appSettings>

In your code:

using System.Configuration;

        private void SendEmail(string emailbody)
        {
                string V = (string)ConfigurationSettings.AppSettings["ConnectionInfo"];
        }

either in you web.config file you can add the following entry:

<system.web>
      <pages theme="standard" maintainScrollPositionOnPostBack="true">
</system.web>
 

or for any page you can set the page directive as follow:

<%@ Page MaintainScrollPositionOnPostback="true" ....

The following line will provide the useragent from the person accesing your web page

 HttpContext.Current.Request.Headers["User-Agent"]

 it would look similar to the following:

useragent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.1.9) Gecko/20100315 Firefox/3.5.9 GTBDFff GTB7.0 (.NET CLR 3.5.30729)

When we are in the process of development it could be quite a pain to login hundreds of times during the day

The following control would ease this process for you

1) download the dll

2) copy the dll into your bin directory

3) drag and drop the Dll onto your toolbox (when viewing a aspx file, press ctrl-alt-X)

4) Then drag and drop the control from the toolbox onto your login page (where you want to be able to quickly login by selecting a user)

Download the dll here

run shell commands:

        private static void RunCommand(string cmdname)
        {
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            p.StartInfo.FileName = cmdname;
            p.Start();
        }

call it with the following command:

            RunCommand("cmd");  // opens a shell command prompt window

make sure to copy the database in the APP_Folder

use the following connection string as template:

<add name="GuestbookConnectionString1" connectionString="Data Source=.\SQLEXPRESS; AttachDBFilename=|DataDirectory|\Guestbook.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
   providerName="System.Data.SqlClient" />

step 1: download sandcastle from one of these 2 locations:

http://sandcastle.codeplex.com/releases/view/13873
http://www.microsoft.com/downloads/details.aspx?familyid=E82EA71D-DA89-42EE-A715-696E3A4873B2&displaylang=en

step 2: Do a straightforward installation

step 3: in visual studio, right-click on your project -> properties -> build -> scroll down and check "XML documentation file"

step 4: build your project

step 5: Run SandcastleGUI, find this under:
C:\Program Files\Sandcastle\Examples\generic 
C:\Program Files (x86)\Sandcastle\Examples\generic    (or for 64bit apps)

step 6: Add your assembly (the dll file which is normally in your application's "bin\debug" folder)

step 7: Also add the XML file which should normally be in your application's "bin\debug" folder)

step 8: Pick any name for your project (I picked "MyTestProject")

step 9: Click "build"

step 10: Locate your project under: (simply just find it that you know where it is)
C:\Program Files\Sandcastle\Examples
C:\Program Files (x86)\Sandcastle\Examples   (64bit)

step 11: Open a command prompt by:
click "Start" -> "run"  and type "cmd" <enter>

step 12: change your directory to where your product output reside:
(e.g. "cd  C:\Program Files\Sandcastle\Examples\MyTestProject\vs2005\chm" )
(where the "MyTestProject.hhc" file is located in my case)

step 13:  Convert the file:
"C:\Program Files\HTML Help Workshop\hhc.exe"  MyTestProject
"C:\Program Files (x86)\HTML Help Workshop\hhc.exe"  MyTestProject    (64 bit)

step 14: you should now have a MyTestProject.chm file

This is a simple example of how to sort a Generic List    List(T)

using System;

using System.Collections.Generic;

public class MySortExample

{

    private static int CompareVehiclesByWeight(Vehicle x, Vehicle y)

    {

        if ((x == null) && (y == null))

             return 0;

        if ((x == null) && (y != null))

             return -1;

        if ((x != null) && (y == null))

             return 1;

        return (x.Weight.CompareTo(y.Weight));

    }

    public static void Main()

    {

        List<Vehicle> Vehicles = new List<Vehicle>();

        Console.WriteLine("\nCapacity: {0}", Vehicles.Capacity);

        Vehicles.Add(VehicleType.Car);

        Vehicles.Add(VehicleType.Bicycle);

        Vehicles.Add(VehicleType.Plane);

        Vehicles.Add(VehicleType.Ship);

        Vehicles.Add(VehicleType.Motorbike);

        Vehicles.Sort(CompareVehiclesByWeight);

    }

} 

You can created multiple sorting algorithms, sorting on different elements/fields and then just call the sort method that you want to use at the appropriate time.

in a similar manner we can format dates:

        //output: Apr 21, 2010
        string s = DateTime.Now.ToString("MMM dd, yyyy");
       
        //output: 2010/Apr/21
        string s = DateTime.Now.ToString("yyyy/MMM/dd");
       
        //output: 2010/04/21 .... 18/00/23/06
        string s = DateTime.Now.ToString("yyyy/MM/dd .... HH/mm/ss/hh");
       
        //output: 20100421
        string s = string.Format("{0:yyyyMMdd}",DateTime.Now);
