I have this code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim connection As New SqlClient.SqlConnection
Dim command As New SqlClient.SqlCommand
Dim adaptor As New SqlClient.SqlDataAdapter
Dim dataset As New DataSet
connection.ConnectionString = ("Data Source=.\SQLEXPRESS;AttachDbFilename=c:\users\korisnik\documents\visual studio 2010\Projects\WindowsApplication46\WindowsApplication46\Database2.mdf;Integrated Security=True;User Instance=True")
command.CommandText = "SELECT * FROM [User] WHERE (username='" + TextBox1.Text + "')AND (password='" + TextBox2.Text + "');"
command.Connection = connection
adaptor.SelectCommand = command
adaptor.Fill(dataset, "1")
Dim count = dataset.Tables(0).Rows.Count)
If count > 0 Then
Form2.Show()
Me.Hide()
Else
MsgBox("Bad username or password!!")
End If
End Sub
Now, I want the code in the loop if. actually when I press the button, and in the textbox is a number which coincides with the number in the database,then get the records from a database in a listview, how to do that?
something like this:
if textbox.text= fild in a database then
print the fild from database to listview
else msg("no item!")
end if
