3. Agree to the warning that you could mess things up
4. Find keyword.url, you probably should not change anything else
5. Double click and change keyword.url string to something else like http://www.google.com/search?q=
6. Note that you cannot just put in the web site domain, you must put in the parameters before your search query. So find your favorite search engine, do a search and grab all the text up to your actual search results. So that a search for "test" in Google returns this, http://www.google.com/search?q=test, but all you need to input into the keyword.url field is http://www.google.com/search?q=

What is an ASP File?

2010-01-30T09:05:00.001-08:00

What is an ASP File?

An ASP file is just the same as an HTML file

An ASP file can contain text, HTML, XML, and scripts

Scripts in an ASP file are executed on the server

An ASP file has the file extension ".asp"

How Does it Work?

When a browser requests an HTML file, the server returns the file

When a browser requests an ASP file, IIS passes the request to the ASP engine on the server

The ASP engine reads the file, line by line, and executes the scripts in the file

Finally, the ASP file is returned to the browser as plain HTML

What is Oops

2010-01-30T09:02:00.000-08:00

WhyObjectOrientedapproach?
A major factor in the invention of Object-Oriented approach is to remove some of the flaws encountered with the procedural approach. In OOP, data is treated as a critical element and does not allow it to flow freely. It bounds data closely to the functions that operate on it and protects it from accidental modification from outside functions. OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. A major advantage of OOP is code reusability.

Some important features of Object Oriented programming are as follows:

Emphasis on data rather than procedure
Programs are divided into Objects
Data is hidden and cannot be accessed by external functions
Objects can communicate with each other through functions
New data and functions can be easily added whenever necessary
Follows bottom-up approach

Concepts of OOP:

Objects
Classes
Data Abstraction and Encapsulation
Inheritance
Polymorphism

BrieflyonConcepts:

Objects

Objects are the basic run-time entities in an object-oriented system. Programming problem is analyzed in terms of objects and nature of communication between them. When a program is executed, objects interact with each other by sending messages. Different objects can also interact with each other without knowing the details of their data or code.

Classes

A class is a collection of objects of similar type. Once a class is defined, any number of objects can be created which belong to that class.

DataAbstractionandEncapsulation

Abstraction refers to the act of representing essential features without including the background details or explanations. Classes use the concept of abstraction and are defined as a list of abstract attributes.

Storing data and functions in a single unit (class) is encapsulation. Data cannot be accessible to the outside world and only those functions which are stored in the class can access it.

Inheritance

Inheritance is the process by which objects can acquire the properties of objects of other class. In OOP, inheritance provides reusability, like, adding additional features to an existing class without modifying it. This is achieved by deriving a new class from the existing one. The new class will have combined features of both the classes.

Polymorphism

Polymorphism means the ability to take more than one form. An operation may exhibit different behaviors in different instances. The behavior depends on the data types used in the operation. Polymorphism is extensively used in implementing Inheritance.

The logical operators compare Boolean expressions and return a Boolean result. In short, logical operators are expressions which return a true or false result over a conditional expression. The table below summarizes them:

Operator	Use
Not	Negation
And	Conjunction
AndAlso	Conjunction
Or	Disjunction
OrElse	Disjunction
Xor	Disjunction

Comparison Operators in VB.NET

2009-12-15T00:00:00.000-08:00

Operator	Use
=	Equality
<>	Inequality
<	Less than
>	Greater than
>=	Greater than or equal to
<=	Less than or equal to

Do Loop in VB.NET

2009-12-14T23:57:00.000-08:00

Do Loop

The Do loop can be used to execute a fixed block of statements indefinite number of times. The Do loop keeps executing it's statements while or until the condition is true. Two keywords, while and until can be used with the do loop. The Do loop also supports an Exit Do statement which makes the loop to exit at any moment. The syntax of Do loop looks like this:

Do[{while | Until} condition]
[statements]
[Exit Do]
[statements]
Loop

Example on Do loop

Module Module1

Sub Main()
Dim str As String
Do Until str = "Cool"
System.Console.WriteLine("What to do?")
str = System.Console.ReadLine()
Loop
End Sub

End Module

While loop Iin VB.NET

2009-12-14T23:56:00.000-08:00

While loop

While loop keeps executing until the condition against which it tests remain true. The syntax of while loop looks like this:

While condition
[statements]
End While

Example on While loop

Module Module1

Sub Main()
Dim d, e As Integer
d = 0
e = 6
While e > 4
e -= 1
d += 1
End While
System.Console.WriteLine("The Loop ran " & e & "times")
End Sub

End Module

For Loop in VB.NET

2009-12-14T23:55:00.000-08:00

For Loop

The For loop is the most popular loop. For loops enable us to execute a series of expressions multiple numbers of times. The For loop in VB .NET needs a loop index which counts the number of loop iterations as the loop executes. The syntax for the For loop looks like this:

For index=start to end[Step step]
[statements]
[Exit For]
[statements]
Next[index]

The index variable is set to start automatically when the loop starts. Each time in the loop, index is incremented by step and when index equals end, the loop ends.

Example on For loop

Module Module1

Sub Main()
Dim d As Integer
For d = 0 To 2
System.Console.WriteLine("In the For Loop")
Next d
End Sub

End Module

Select....Case Statement in VB.NET

2009-12-14T23:53:00.001-08:00

Select....Case Statement

The Select Case statement executes one of several groups of statements depending on the value of an expression. If your code has the capability to handle different values of a particular variable then you can use a Select Case statement. You use Select Case to test an expression, determine which of the given cases it matches and execute the code in that matched case.

The syntax of the Select Case statement looks like this:

Select Case testexpression
[Case expressionlist-n
[statements-n]] . . .
[Case Else elsestatements]
End Select

Example

Imports System.Console
Module Module1

Sub Main()
Dim keyIn As Integer
WriteLine("Enter a number between 1 and 4")
keyIn = Val(ReadLine())

Select Case keyIn
Case 1
WriteLine("You entered 1")
Case 2
WriteLine("You entered 2")
Case 3
WriteLine("You entered 3")
Case 4
WriteLine("You entered 4")
End Select

End Sub

End Module

If....Else statement in vb.net

2009-12-14T23:49:00.002-08:00

Conditional Statements

If....Else statement

If conditional expression is one of the most useful control structures which allows us to execute a expression if a condition is true and execute a different expression if it is False. The syntax looks like this:

If condition Then
[statements]
Else If condition Then
[statements]
-
-
Else
[statements]
End If

Understanding the Syntax

If the condition is true, the statements following the Then keyword will be executed, else, the statements following the ElseIf will be checked and if true, will be executed, else, the statements in the else part will be executed.

Example

Imports System.Console
Module Module1

Sub Main()
Dim i As Integer
WriteLine("Enter an integer, 1 or 2 or 3")
i = Val(ReadLine())
'ReadLine() method is used to read from console

If i = 1 Then
WriteLine("One")
ElseIf i = 2 Then
WriteLine("Two")
ElseIf i = 3 Then
WriteLine("Three")
Else
WriteLine("Number not 1,2,3")
End If

End Sub

End Module

Access Specifiers In VB.NET

2009-12-14T23:49:00.001-08:00

Access Specifiers

Access specifiers let's us specify how a variable, method or a class can be used. The following are the most commonly used one's:

Public: Gives variable public access which means that there is no restriction on their accessibility
Private: Gives variable private access which means that they are accessible only within their declaration content
Protected: Protected access gives a variable accessibility within their own class or a class derived from that class
Friend: Gives variable friend access which means that they are accessible within the program that contains their declaration
Protected Friend: Gives a variable both protected and friend access
Static: Makes a variable static which means that the variable will hold the value even the procedure in which they are declared ends
Shared: Declares a variable that can be shared across many instances and which is not associated with a specific instance of a class or structure
ReadOnly: Makes a variable only to be read and cannot be written

Namespaces in VB.NET

2009-12-14T23:40:00.000-08:00

Namespaces

A namespace is a collection of different classes. All VB applications are developed using classes from the .NET System namespace. The namespace with all the built-in VB functionality is the System namespace. All other namespaces are based on this System namespace.

Some Namespaces and their use:

System: Includes essential classes and base classes for commonly used data types, events, exceptions and so on
System.Collections: Includes classes and interfaces that define various collection of objects such as list, queues,
hash tables, arrays, etc
System.Data: Includes classes which lets us handle data from data sources
System.Data.OleDb: Includes classes that support the OLEDB .NET provider
System.Data.SqlClient: Includes classes that support the SQL Server .NET provider
System.Diagnostics: Includes classes that allow to debug our application and to step through our code
System.Drawing: Provides access to drawing methods
System.Globalization: Includes classes that specify culture-related information
System.IO: Includes classes for data access with Files
System.Net: Provides interface to protocols used on the internet
System.Reflection: Includes classes and interfaces that return information about types, methods and fields
System.Security: Includes classes to support the structure of common language runtime security system
System.Threading: Includes classes and interfaces to support multithreaded applications
System.Web: Includes classes and interfaces that support browser-server communication
System.Web.Services: Includes classes that let us build and use Web Services
System.Windows.Forms: Includes classes for creating Windows based forms
System.XML: Includes classes for XML support

The Architecture of Data Binding

2009-12-14T23:35:00.001-08:00

1. Create Connection Object. The connection that the users create, forms the basis for all other activities. In doing so the user creates a connect string and also a connection object that provides connection to the database.

2. Create DataSet and DataAdapter. Then the user proceeds to set the Data Binding property of the text box. At this stage the Visual Studio creates a DataSet and a DataAdaptor. The “Select ... “ statement for creating the DataSet is also autogenerated based on the selections the user has made in the Data Source configuration wizard.

3. Call the fill method of the DataAdapter to fill the dataset. This also adds a line of code that fills the dataset using the data adapter and the connection object . At the end of it all the data from the selected data source is available for the control when the form loads.

Data providers for other objects in .NET Framework

2009-12-14T23:30:00.000-08:00

Binding data to form controls allows the user access data from databases as well as data in other structures, such as arrays and collections which support IList interface. The data providers for other objects in .NET Frameworkare listed below:

1. DataColumn object. The users can simple-bind a control (such as a TextBox control's Text property) to a column within a data table.

2. DataTable object. The user can complex-bind a control to the information contained in a data table (such as binding the DataGrid control to a data table) using the default view of the DataTable.

3. DataView object. The users can simple- or complex-bind to the data within a data view. However this provides a fixed snapshot of the data.

4. DataSet object. The users can simple- or complex-bind to the data within a dataset using the default view

5. DataView Manager Object. It functions like DataView, with a difference that this snapshot comes with relationships that exists between the tables as seen in a DataSet.

Differences Between ADO and ADO.NET

2009-12-14T23:16:00.000-08:00

ADO and ADO.NET are different in several ways:

ADO works with connected data. This means that when you access data, such as viewing and updating data, it is real-time, with a connection being used all the time. This is barring, of course, you programming special routines to pull all your data into temporary tables.

ADO.NET uses data in a disconnected fashion. When you access data, ADO.NET makes a copy of the data using XML. ADO.NET only holds the connection open long enough to either pull down the data or to make any requested updates. This makes ADO.NET efficient to use for Web applications. It's also decent for desktop applications.
ADO has one main object that is used to reference data, called the Recordset object. This object basically gives you a single table view of your data, although you can join tables to create a new set of records. With ADO.NET, you have various objects that allow you to access data in various ways. The DataSet object will actually allow you to store the relational model of your database. This allows you to pull up customers and their orders, accessing/updating the data in each related table individually.
ADO allows you to create client-side cursors only, whereas ADO.NET gives you the choice of either using client-side or server-side cursors. In ADO.NET, classes actually handle the work of cursors. This allows the developer to decide which is best. For Internet development, this is crucial in creating efficient applications.
Whereas ADO allows you to persist records in XML format, ADO.NET allows you to manipulate your data using XML as the primary means. This is nice when you are working with other business applications and also helps when you are working with firewalls because data is passed as HTML and XML.

Data Controls Used in Windows Forms

2009-12-14T23:09:00.000-08:00

Control Name&Purpose

Eight data controls are available for Windows forms

DataSet

This control is used in conjunction with the other data controls, storing the results that are returned by commands and the DataAdapters. Unlike the recordset from ADO and DAO, the DataSet actually brings back a hierarchical view of the data. Using properties and collections in the DataSet object, you can get all the way down to individual tables, rows, and columns.

OleDbDataAdapter

This control stores and manages the commands you want to use against an OleDb provider such as Jet, Oracle, or SQL Server. The commands for selecting, updating, inserting, and deleting records can be used. The Connection against which to use the commands is also tracked.

OleDbConnection

This control maintains connection information for an OleDb provider. This control is used with the OleDbDataAdapter.

OleDbCommand

Similar to the ADO command object, this control allows you to execute SQL statements or stored procedures to either run bulk operations or return data.

SqlDataAdapter

This control is the same as the OleDbDataAdapter except that it is for use only against SQL Server stores.

SqlConnection

This control is the same as the OleDbConnection except that it is for use only against SQL Server stores.

SqlCommand

This control is the same as the OleDbCommand except that it is for use only against SQL Server stores.

DataView

This control creates multiple views of the same table. This includes looking at data in various states such as deleted, changed, or sorted differently

DIFFERENT DATETIME, DATE, AND TIMESTAMP FORMAT IN MY SQL

2009-12-08T23:49:00.000-08:00

As a string in either 'YYYY-MM-DD HH:MM:SS' or 'YY-MM-DD HH:MM:SS' format. A “relaxed” syntax is allowed: Any punctuation character may be used as the delimiter between date parts or time parts. For example, '98-12-31 11:30:45', '98.12.31 11+30+45', '98/12/31 11*30*45', and '98@12@31 11^30^45' are equivalent.
As a string in either 'YYYY-MM-DD' or 'YY-MM-DD' format. A “relaxed” syntax is allowed here, too. For example, '98-12-31', '98.12.31', '98/12/31', and '98@12@31' are equivalent.
As a string with no delimiters in either 'YYYYMMDDHHMMSS' or 'YYMMDDHHMMSS' format, provided that the string makes sense as a date. For example, '20070523091528' and '070523091528' are interpreted as '2007-05-23 09:15:28', but '071122129015' is illegal (it has a nonsensical minute part) and becomes '0000-00-00 00:00:00'.
As a string with no delimiters in either 'YYYYMMDD' or 'YYMMDD' format, provided that the string makes sense as a date. For example, '20070523' and '070523' are interpreted as '2007-05-23', but '071332' is illegal (it has nonsensical month and day parts) and becomes '0000-00-00'.
As a number in either YYYYMMDDHHMMSS or YYMMDDHHMMSS format, provided that the number makes sense as a date. For example, 19830905132800 and 830905132800 are interpreted as '1983-09-05 13:28:00'.
As a number in either YYYYMMDD or YYMMDD format, provided that the number makes sense as a date. For example, 19830905 and 830905 are interpreted as '1983-09-05'.

HOW TO CHECK SIM-LOCK IN NOKIA MOBILES

2009-11-28T23:56:00.000-08:00

CHECK SIM-LOCK
Note - If you bought your Nokia on UK Vodafone or UK Cellnet you do not need to check this because they both transmit on GSM900, and they don't lock the phones. However if you bought your phone on UK Orange or UK One2one your phone may be blocked. The reason is that they both transmitt on GSM1800. To make a call on GSM1800 you need what is known as a "Dual band" phone. A dual band phone is able to transmit on both GSM900 and GSM1800, so they lock the phones so you can't use it with any other network simcard. If you find that your phone is locked you can try different software to unlock it. (we havn't found one that works yet), or you can ask your service provider who will gladly exchange the 10 digit code for about £35.
This is how to check the status of the 4 different locks. Aslo don't try entering the wrong number, because after 3 times it will block the phone for good.
There are 4 different locks on your Nokia phone.
COUNTRY-LOCK
NETWORK-LOCK
PROVIDER-LOCK
SIMCARD-LOCK
The code to read out the sim-lock status of your phone is #PW+(MASTERCODE)+(Y)#
# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4
The master code is a secret code. The code has 10 digits, To read out the sim-lock status you can enter every combination you want!
"Y" Shows the status of the network-lock. Here you can enter a number from "1" to "4". The "4" is for the sim-card lock.

SIM-LOCK CHECKS
#PW+1234567890+1# = GIVES PROVIDER-LOCK STATUS
#PW+1234567890+2# = GIVES NETWORK-LOCK STATUS
#PW+1234567890+3# = GIVES COUNTRY-LOCK STATUS
#PW+1234567890+4# = GIVES SIM-CARD-LOCK STATUS.
