Next, Previoust......Button Coding in VB.NET
First Declare two variables n and mx.............
Dim n As Integer = 0
Dim mx As Integer
Make one function for moving........
Public Sub next1()
TextBox1.Text = ds.Tables(0).Rows(n).Item(0).ToString
TextBox2.Text = ds.Tables(0).Rows(n).Item(1).ToString
TextBox3.Text = ds.Tables(0).Rows(n).Item(2).ToString
End Sub
Here, it will show 'n' th row's data and for first record n = 0 and for last data n = mx -1
MX means maximum data but data start indexing start with 0 so last data is n= mx-1
For first button........
For Last Button....
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
For Next Button.......
For Previous Data............
Dim n As Integer = 0
Dim mx As Integer
Make one function for moving........
Public Sub next1()
TextBox1.Text = ds.Tables(0).Rows(n).Item(0).ToString
TextBox2.Text = ds.Tables(0).Rows(n).Item(1).ToString
TextBox3.Text = ds.Tables(0).Rows(n).Item(2).ToString
End Sub
Here, it will show 'n' th row's data and for first record n = 0 and for last data n = mx -1
MX means maximum data but data start indexing start with 0 so last data is n= mx-1
For first button........
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
cn.Open()
n = 0
next1()
cn.Close()
End Sub
For Last Button....
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
cn.Open()
mx = ds.Tables(0).Rows.Count
n = mx - 1
next1()
cn.Close()
End Sub
For Next Button.......
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
cn.Open()
mx = ds.Tables(0).Rows.Count
If (n <> mx - 1) Then
n = n + 1
next1()
Else
MsgBox("This is your last data")
End If
cn.Close()
End Sub
For Previous Data............
Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
cn.Open()
mx = ds.Tables(0).Rows.Count
If (n <> 0) Then
n = n - 1
next1()
Else
MsgBox("This is your first data")
End If
cn.Close()
End Sub
cn.Open()
mx = ds.Tables(0).Rows.Count
If (n <> 0) Then
n = n - 1
next1()
Else
MsgBox("This is your first data")
End If
cn.Close()
End Sub

OLEDB Coding for Techno Stuff Readers
Sorry Friends for being late but its beneficial to revise again...................
Specially Sandeep for YOU......: )
Create one database named emp and make one table emp which contains three coulmns like
id = datatype autonumeric
Name = TEXT
City= TEXT
First of all we have to imports the data and oledb in our coding section
Imports System.Data
Imports System.Data.OleDb
Imports System.Data.OleDb
Then we have to declare connection object and dataset in global declaration area because we will need it in many private events like button's click event......
Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\emp.mdb")
Dim ds As New DataSet
Now place four textbox, eight buttons and one data-grid-view on design portion......
Public Sub selectQuery()
'We made one function for select query and will use it in every place where select query neededDim adp As New OleDbDataAdapter("Select * from emp", cn)
ds.Clear()
adp.Fill(ds)
DataGridView1.DataSource = ds.Tables(0)
End Sub
First code for Inserting Data.......Double Click On Insert Button.........
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
cn.Open()
Dim cmd As New OleDbCommand("insert into emp (Name, City) values ('" &TextBox1.Text &"', '"& TextBox2.Text &"') ", cn)
'we inserted data from textbox into emp table, we didnt included id because it's datatype is autonumeric
cmd.ExecuteNonQuery()
MsgBox("Data Inserted Successfully", MsgBoxStyle.Information, vbOK)
selectQuery()
DataGridView1.DataSource = ds.Tables(0)
End Sub
Delete Query............
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
cn.Open()
Dim cmd As New OleDbCommand("Delete * from emp where id = " & TextBox1.Text & " ", cn)
cmd.ExecuteNonQuery()
selectQuery()
cn.Close()
End Sub
cn.Open()
Dim cmd As New OleDbCommand("Delete * from emp where id = " & TextBox1.Text & " ", cn)
cmd.ExecuteNonQuery()
selectQuery()
cn.Close()
End Sub
Update Query...............
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Clickcn.Open()
Dim cmd As New OleDbCommand("update emp set Name='" & TextBox2.Text & "' where id = " & TextBox1.Text & " ", cn)
cmd.ExecuteNonQuery()
selectQuery()
cn.Close()
End Sub
Search Button Coding......................
You can search from database by two way. We will see first method double click on search button.
and write below code.
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
cn.Open()
Dim adp As New OleDbDataAdapter("Select * from emp where name='" & TextBox4.Text & "' ", cn)
ds.Clear()
adp.Fill(ds)
DataGridView1.DataSource = ds.Tables(0)
cn.Close()
End Sub
Search with Text Changed Event.......
Private Sub TextBox4_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox4.TextChanged
cn.Open()
Dim adp As New OleDbDataAdapter("Select * from emp where City like '" & TextBox4.Text & "%' ", cn)
ds.Clear()
adp.Fill(ds)
DataGridView1.DataSource = ds.Tables(0)
cn.Close()
End Sub
We will see next, previous and last button coding in next article till then enjoy and read Technology Stuff at Present 2 Upcoming
cn.Open()
Dim adp As New OleDbDataAdapter("Select * from emp where City like '" & TextBox4.Text & "%' ", cn)
ds.Clear()
adp.Fill(ds)
DataGridView1.DataSource = ds.Tables(0)
cn.Close()
End Sub
We will see next, previous and last button coding in next article till then enjoy and read Technology Stuff at Present 2 Upcoming

Different Desktop Environments on Linux
Different Desktop Environments on Linux
All computers are nothing without Operating Systems, much the same as the principle that power is nothing without control. Lamborghini could make the fastest car in the world next year, nothing coming even relatively close to it. However if they weld the doors closed and fill the whole cabin with cement, so there is no way to ever drive or operate the car, the whole entire thing is worthless. Think of this as a computer without an operating system, it’s a wild beast, waiting to be tamed. When you choose an OS not only are you establishing a whole “front-end” from which you can operate the computer, your pouring a little bit of yourself in it as well. Changing the color of the car, from my earlier metaphor if you will.
There are a TON of things that happen when you install an OS, but you only see the graphical parts of it, the “graphical user interface” or GUI. Obviously, if that's the main thing your seeing, its fairly important to you on every level. Linux however, took this whole concept a step further, and established several “flavors” of GUI for your desktop on your Linux OS. Wikipedia describes a desktop environment as just that: A Desktop Environment (DE) commonly refers to a style of graphical user interface (GUI) derived from the desktop metaphor that is seen on most modern personal computers.
This is very important, because if you’ve ever used Linux AT ALL, you know that choice is everything. It’s not about just using “what works” or “whats provided”, its about carving your own path based on precisely what YOU want. If you don’t like the way the taskbar functions on one particular distribution or “distro” of Linux, and you think that the support is poor and you could never see yourself using it, just choose a different one! It’s about having absolutely everything as close to tailor-made to your specific liking as you can, hence why desktop environments are so important.
It’s the GUI, it’s what you will be looking at and toying with directly for hours and hours and hours, lets spend some time finding out what you want, and let’s do it right. The problem being that I really can’t just choose one for you, it’s not that easy. It’s purely aesthetics, it really is, however things like that do in fact matter when your spending that much time dealing with it. Listed below is a number of screenshots of different DE’s, or desktop environments, notice that the differences are minimal, but there is certainly is still a difference between each of them.
Gnome, KDE, XFCE, and LXDE are just a few of Linux distro’s most popular DE’s, mostly just because they are the main ones. There is a direct correlation between the name of the DE and the distro of Linux that your using. If you look up things regarding Ubuntu, you will notice that it comes standard with the GNOME DE. However, if you look at Xubuntu, a different branch or “flavor” of Ubuntu, you might wonder what the difference between the two is. Sure enough, the X stands for the XFCE type DE that Xubuntu uses, meaning that you can deduce that Xubuntu is the same as Ubuntu, except with an XFCE DE, without even researching if you’d seriously want to try the distro or not you already know what DE it uses.
Difference between Internal And External Command in Linux.
Internal commands are the commands that are executed
directly by the shell. These commands will not have a
separate process running for each.
External commands are the commands that are executed by the
kernal. These commands will have a process id running for
it.
Internal Commands: Echo, CD
External Commands: cat, ls

Microsoft Surface Computer
Microsoft Launches New Product Category: Surface Computing Comes to Life in Restaurants, Hotels, Retail Locations and Casino Resorts.
Microsoft Surface Computing brings to life a whole new way to interact with information that engages the senses, improves collaboration and empowers consumers. By utilizing the best combination of connected
software, services and hardware, Microsoft is at the forefront of developing surface computing products that push computing boundaries, deliver new experiences that break down barriers between users and technology, and provide new opportunities for companies to engage with people.
First commercially available surface computer from Microsoft breaks down barriers and provides effortless interaction with information using touch, natural gestures and physical objects.
Microsoft's definition of surface computing: direct interaction (for example, you might "dip" your finger on an on-screen paint palette, and then use your finger to draw on the screen); multi-touch contact, so the screen can react to multiple fingers and inputs simultaneously; multi-user experience, so multiple people can gather around and interact with the screen simultaneously; and object recognition, so the surface can recognize tagged objects and interact with them.
Direct interaction. Users can actually “grab” digital information with their hands, interacting with content by touch and gesture, without the use of a mouse or keyboard. You can buy songs from a virtual music store and drag them directly into a Zune music player that you’ve placed on the glass. You can set a cellphone down on the table — and copy photos into it just by dragging them into the cellphone’s zone.
Multi-touch. Surface computing recognizes many points of contact simultaneously, not just from one finger like a typical touch-screen, but up to dozens of items at once.
Multi-user. The horizontal form factor makes it easy for several people to gather around surface computers together, providing a collaborative, face-to-face computing experience.
Object recognition. Users can place physical objects on the surface to trigger different types of digital responses, including the transfer of digital content.
