You can write practically any SQL into the SqlCommand object. All you need to do is write the SQL to perform the back up and perform ExecuteNonQuery() on the SqlCommand object.

Hi, I am now working on a data compare and copy for datagrid. Below i have the codes the open up this csv file and attached it to the datagrid1.
I am now finding a way to
1. Type in "123123" into the textbox
2. Click a button
3. Compare it with the datagrid1(which has the opened csv file) or compare directly with csv file
4. Copy the whole row on which the "123123" is found and paste into another field or datagrid for display
Public Function Import()<br />
<br />
Dim myPath As String = "c:\testing.csv"<br />
<br />
Try<br />
<br />
Dim objDataSet As System.Data.DataSet<br />
Dim objAdapter As System.Data.OleDb.OleDbDataAdapter<br />
<br />
strConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source='" & myPath & " '; " & "Extended Properties=Excel 8.0;")<br />
objAdapter = New System.Data.OleDb.OleDbDataAdapter("select * from [sheet1$]", strConnection)<br />
objDataSet = New System.Data.DataSet<br />
objAdapter.Fill(objDataSet)<br />
DataGrid1.DataSource = objDataSet.Tables(0).DefaultView<br />
strConnection.Close()<br />
<br />
Catch ex As Exception<br />
<br />
Dim er As String<br />
<br />
strConnection.Close()<br />
<br />
End Try
thanks

Use the objDataSet.Tables(0).Select("ColumnName = "& YourTextBox.Text")
This will return DataRow Collection that you can manage the way you wish

im suppose to write a 4 page document on "How does Open source cater for what Microsoft’s ADO.Net provide"
then i have to come up with example aswell.
any help will be appeciated

Ask yourself these questions:
In what context? Are you talking about open source targetting the .NET platform only?
Is it asking what open source frameworks replace ADO.NET? (None that I know of. There are some that are a wrapper around ADO.NET, but ADO.NET is still being used to access the underlying database)
What does ADO.NET do? What open source equivalents are there? How do each of these technologies work? Can you show the exact same task being performed in ADO.NET versus an open source equivalent?

Make the textbox Readonly... or
you can write e.handled=true in Keypress event of that textbox.

AFAIK, a scanner is a keyboard wedge - it just outputs the characters read into the text box that has control at that point. If you make the textbox read-only or handle the keypress and throw the key away, you might not get any data into your text box at all.

Like the other person said, most barcode scanners are keyboard wedges. This means that they are, in fact, a keyboard. There is no way to tell the difference between the user hitting keys on the keyboard and the key data comming from the scanner. To Windows, and your app, they are exactly the same. So, to answer your question, no there isn't a way to do what you want using the scanner you have.
There are, on the other hand, barcode scanners out there that work on Ethernet that may do what you want, but they cost considerably more money to buy.

Hi,
for most barcode readers, you can set a prefix and postfix string that they emit around
the text scanned; read the reader's doc.
have your TextBox reject everything that does not have the prefix+postfix,
and remove those once you consume the data.
Or just remove the keyboard!
