Each checkbox is a simple True/False value. Unless you're using a TriState checkbox that is...

If you're using a normal checkbox, you check either use one database field for each checkbox, or you can assign bit flag values to each checkbox and "OR" those togther and save the resulting value.

try this

set AutoPostBack="true" in Checkbox at design time and also set "OnCheckedChanged" event which will call the code behind function every time when user Select/Deselect CheckBox ...

SO when OnCheckedChanged Event is called in code behind you can write your code which will hit the database and before that check which checkbox is checked by CheckboxName.Checked = True and then call a function which will insert checked Checkbox value into database

Huh? are you the same person who posted the question? Anyway, no one will help you if all you want is the code. Its not the way it works here. You should have started with something and post questions here if you were stuck somewhere.

Can't say much.

Have a db named test, a table named activity with fields ActivityID and Activities

Got a form with one textbox named txtactivity. Visible property set to false.

got a label with text Activities.
Got Six checkboxes with six different options.
And of course a button
Code works but needs some extra touch. If you can make it shoter, tha'll be cool.

Public Class Form1
    'path variable use for Get application running path
    Dim path As String = (Microsoft.VisualBasic.Left(Application.StartupPath, Len(Application.StartupPath) - 9))

    Dim cmd As SqlCommand
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If CheckBox1.Checked = False And CheckBox2.Checked = False And CheckBox3.Checked = False And CheckBox4.Checked = False And CheckBox5.Checked = False And CheckBox6.Checked = False Then
            MsgBox("Please select atleast one activity")
            If CheckBox1.Checked Then
                CheckBox1.Text = CheckBox1.Text
            Else : CheckBox1.Text = ""

            Dim sql As String = "INSERT INTO Activity VALUES(@Activities)"
            Dim cmd As New SqlCommand(sql, con)
            cmd.Parameters.AddWithValue("@Activities", txtactivity.Text)
            MessageBox.Show("Information has been saved", "Save", MessageBoxButtons.OK)

Apart from the fact the original question is over 2 years old ... what is the point of the lines like "CheckBox1.Text = CheckBox1.Text"???
