Asp.net Features and Advantages

ASP.NET is a compiled, .NET-based environment; you can code the applications in any .NET compatible language, including Visual Basic .NET, C#, and JScript .NET. Additionally, the entire .NET Framework is available to any ASP.NET application.

ASP.NET has been designed with scalability in mind, with features specifically tailored to improve performance in clustered and multiprocessor environments. With built in Windows authentication and per-application configuration, you can be assured that your applications are secure.

You can use Web Forms or XML Web services when creating an ASP.NET application, or combine both depending on your need. Both of them allows you to use authentication schemes, cache frequently used data, or customize application's configuration.

ASP.Net allows programmers to develop web applications that interface with a database. The advantage of ASP.Net is that it is object-oriented and has many programming tools that allow for faster development and more functionality.

There are 2 aspects of ASP.Net make it fast, compiled code and caching.

Prior to DOT Net Framework, the code was interpreted into machine language when your website visitor views your page. Now, with ASP.Net the code is compiled into machine language before your visitor ever comes to your site.

Caching is the storage of information that will be reused in a memory location for faster access in the future. ASP.Net allows programmers to set up pages or areas of pages that are commonly reused to be cached for a set period of time to improve the performance of web applications. I have used caching in many of my applications with few records, static and frequently used data.

ASP.Net automatically recovers from memory leaks and errors to make sure that your website is always available to your visitors. Programmers can actually write their code in any of the supported .Net languages like VB.Net, C#, and JScript.Net. In the Learning series, we will be using C# since it’s the widely used language across many companies.

An ASP.NET Framework application is deployed to a server simply by copying the necessary files to the server. No server restart is required, even to deploy or replace running compiled code.

Security is one of the major advantage, you can use built in Windows authentication and also you can set the security configuration by application.

Code for check box check or uncheck in Grid View Using C#.net

-------------First You need to add the javascript code-----------------


var TotalChkBx;
var Counter;

window.onload = function()
{
//Get total no. of CheckBoxes in side the GridView.
TotalChkBx = parseInt('<%= this.gvCheckboxes.Rows.Count %>');
//Get total no. of checked CheckBoxes in side the GridView.
Counter = 0;
}


function HeaderClick(CheckBox)
{
//Get target base & child control.
var TargetBaseControl = document.getElementById('<%= this.gvCheckboxes.ClientID %>');
var TargetChildControl = "chkBxSelect";

//Get all the control of the type INPUT in the base control.
var Inputs = TargetBaseControl.getElementsByTagName("input");

//Checked/Unchecked all the checkBoxes in side the GridView.
for(var n = 0; n < Inputs.length; ++n)
if(Inputs[n].type == 'checkbox' && Inputs[n].id.indexOf(TargetChildControl,0) >= 0)
Inputs[n].checked = CheckBox.checked;
//Reset Counter
Counter = CheckBox.checked ? TotalChkBx : 0;
}

function ChildClick(CheckBox, HCheckBox)
{
//get target base & child control.
var HeaderCheckBox = document.getElementById(HCheckBox);

//Modifiy Counter;
if(CheckBox.checked && Counter <> 0)
Counter--;

//Change state of the header CheckBox.
if(Counter < TotalChkBx)
HeaderCheckBox.checked = false;
else if(Counter == TotalChkBx)
HeaderCheckBox.checked = true;

Add onclick attribute for HeaderCheckbox like this:

In asp:CheckBox tag, add this: onclick="javascript:HeaderClick(this);"


Now add the following code in row_created event of GridView

if (e.Row.RowType == DataControlRowType.DataRow && (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate))
{
CheckBox chkBxSelect = (CheckBox)e.Row.Cells[1].FindControl("chkBxSelect");
CheckBox chkBxHeader = (CheckBox)this.gvCheckboxes.HeaderRow.FindControl("chkBxHeader");

chkBxSelect.Attributes["onclick"] = string.Format("ChildClick(this,'{0}');", chkBxHeader.ClientID);
}

Thats it!!!!!!!!!!

3. Click on "Remove..."
4. On the confirmation screen click "Yes"
5. When it has finished click "Close" and then "Exit" to quit the installer

Whilst the Oracle installer removes many components there are a number of things that it leaves behind. In order to completely remove all traces of Oracle the following additional steps will need to be taken:

1. Stop any Oracle services that have been left running. (Start > Settings > Control Panel > Services.)
Services which I have found left behind are 'OracleOraHome90TNSListener' and 'OracleServiceORACLE'. However there may be others depending on your installation. Look for any services with names starting with 'Oracle'.
2. Run regedit (Start > Run > Enter "regedit", click "Ok"), find and delete the following keys:

HKEY_LOCAL_MACHINE
\SOFTWARE
\ORACLE

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\EventLog
\Application
\Oracle.oracle

Note: I have had it reported that some people also have registry entries saved under HKEY_CURRENT_USER\SOFTWARE\ORACLE, this registry entry may be created by some Oracle utilities. If it exists then delete it.
3. Delete the Oracle home directory:
"C:\Oracle"
This will also remove your database files (unless you located them elsewhere, in which case you will need to delete them separately).
4. Delete the Oracle program Files directory:
"C:\Program Files\Oracle"
5. Delete the Oracle programs profile directory:
"C:\Documents and Settings\All Users\Start Menu\Programs\Oracle - OraHome90"
if you did not first run the Oracle installer to remove Oracle then there may be other Oracle profile group directories to remove.
6. Some of the Oracle services may be left behind by the uninstall. Open ‘services’ on the control panel, make a note of which Oracle services remain and see the notes ‘How to remove a service’ to remove them.
7. If you didn't first run the Oracle Installer to remove Oracle then you may have some references to Oracle left in the path. To remove these: Start > Settings > Control Panel > System > Advanced > Environment Variables, look at both the use and system variable 'PATH' and edit them to remove any references to Oracle.

Acknowledgements: My appreciation to Alistair Jones for help on this procedure and for encouragement to write it.

These notes have been tested with Oracle 9i under Windows XP.

Access Masterpage control from Content Page

Master Page Controls can be accessed from Content pages using 'Master' keyword
Example: Suppose a label with id 'Label1' is in the master page.Then a reference to this control can be used in any content page.Now.I am trying to write down the text value of that label in content page like this:

Label mylabel=(Label)Master.FindControl("Label1");
Response.Write(mylabel.text);

About CAPTCHA

Have you heard about "Captcha".Yes,You have seen it but wouldn't have heard it before.
It is nothing but -Completely Automated Public Turing test to tell Computers and Humans Apart

Web sites are increasingly under spam attack from automated scripts. “CAPTCHAs” help Web sites to distinguish between human and machine users by forming a problem that is easy for humans to solve, but difficult for machines to solve.

CAPTCHA can control many automated spam attacks against Web sites, but without careful planning, it can also cause problems.

A Sample CAPTCHA Image

Because CAPTCHAs rely on perception, users unable to perceive a CAPTCHA (for example, due to a disability or because it is difficult to read) will be unable to perform the task protected by a CAPTCHA.

How to find visitors online using asp.net

Hey! have you ever tried to put the number of visitors online on your aspx page?
Ya.Try this-
Just paste the follwing code in global.asax file:

void Application_Start(object Sender, EventArgs E)
{
// Set our user count to 0 when we start the server
Application["ActiveUsers"] = 0;

}

void Session_Start(object Sender, EventArgs E)
{

Session["Start"] = DateTime.Now;
Session.Timeout = 1;
Application.Lock();
Application["ActiveUsers"] = (int)Application["ActiveUsers"] + 1;
Application.UnLock();

}

void Session_End(object Sender, EventArgs E)
{
Application.Lock();
Application["ActiveUsers"] = (int)Application["ActiveUsers"] - 1;
Application.UnLock();
Session.Clear();
Session.Remove("Start");
}

And get the Application["ActiveUsers"] where ever you need it!!!
Ex:label1.text=Application["ActiveUsers"].ToString();

Installing font in to machine using .net

Fonts can be installed into the client's machine through c#.
First everyone tries to copy the file to the "C:\Windows\Fonts"(assuming OS is installed on C drive).And gets a flower kept in the ears.Ya.Actually, An application can use a font to draw text only if that font is either resident on a specified device or installed in the system font table.
The font table is an internal array that identifies all nondevice fonts that are available to an application.A method exists to access this table.
Now let us see the code:

using System;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.IO;
using System.Runtime.InteropServices;

public partial class Class_Name : System.Web.UI.Page
{
[DllImport("gdi32")]
public static extern int AddFontResource(string lpFileName);

protected void Page_Load(object sender, EventArgs e)
{
File.Copy(Server.MapPath("mfdev010.ttf"), "C:\\Windows\\fonts\\mfdev010.ttf");

// Adding the font ..
AddFontResource("mfdev010.ttf");
Response.Write("Installation successful");
}

}



Explanation:
Here what i have done is
1.Put the font file in the application directory.
2.First copy the font file to the windows(font location).Be careful to check.some machines may have OS installed in other drives other than C drive.
3.Add the font to the font resource file by using the "AddFontResource" method.However,in order to use this function,you need to write an api(as shown above) using gdi32 dll.

Now as you start debugging,as page loads font gets installed.
Have nice coding!!!
Bye.
