=====
String are immutable object.Its value cannot be changed(constant).String object are readonly.If you create one instance of string and change the value of string then it create new instance.
String Buffer
=========
String Buffer is mutable.Its Value can be Changed.If you create one instance and append the text without creating a new instance
Example:
======
String
=====
String str=”welcome”;
str + = “to fordevs”;
String Buffer
=========
StringBuffer strbuff=new StringBuffer(“welcome”);
strbuff.append(“to fordevs”);
Both code give same output but Second approach much faster than first one.

March 23rd, 2010 joy Normally if we focus a textbox control the cursor would be in the start of the textbox.But when there is text already in the textbox it would be annoying if the cursor is in start.It would be better if the cursor is at the end of content in texbox.
Thus to position the cursor at the end of the text content of a textBox control,we have to call the select method and specify the selection start position to the length of the text and a selection length to 0.
txtExample.focus(); txtExample.Select(txtExample.Text.Length, 0);

March 21st, 2010 Kathirvel KG Problem:
I was wondering how to override the DNS locally. There is a server in my network having static IP and has a registered Domain name. My local network doesn’t allow me to connect to internet and the server is part of my network, so how do I connect to this server using the same domain name instead of LAN IP or system name.
Solution:
When you do this you are just bypassing the DNS.

January 26th, 2010 joy WPF does not allow text wrapping for label control.Thus to wrap a label with a fixed width,we have to place the TextBlock control inside the label control and set its TextWrapping property to “Wrap”.
<Label Width=”50″>
<TextBlock TextWrapping=”Wrap”> I am label with width 50</TextBlock>
</Label>

OpenID
Fed up with creating new accounts for multiple websites, here comes OpenID for the rescue. It allows you to use an existing account to sign in to multiple websites without ‘sign up’. OpenID replaces the common login process that uses a login name and password for every website.
An OpenID is in the form of a unique URL (e.g., http:\\me.yahoo.com\testid), which is authenticated by the user’s OpenID provider. Some of the websites who supports, allows and provides OpenID are Yahoo, Google, ZOHO, Microsoft, AOL, PayPal, Verisign. The OpenID doesn’t rely on a central authority to authenticate the user. The OpenID protocol leaves the type of authentication to the provider, the authentication forms may include passwords and biometrics.
Let us create a OpenID with Yahoo!
Yahoo! OpenID
OpenID generated
Custom OpenID
Let us check how to use the OpenID.
The major advantage of an OpenID is you need not create a new account for every website you visit, instead create an OpenID and use the same account to log into all websites you visit.
