Hello,

I have a backend database as my bindingsource, and am attempting to use a Save command button to reflect the changes on my form into my database.  Please advise.

Thank you.

Option Explicit On

Imports System
Imports System.Data
Imports System.Data.OleDb
Imports System.Data.SqlClient
Imports System.Windows.Forms.DataGridView

Public Class frmInput
    Dim sqlString As String = "SELECT * FROM tblInsuranceClaim"
    Dim ConnString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Documents and Settings\Administrator\Desktop\MyDBBackend.mdb;User ID=admin"
    Dim OleDBConn1 As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(ConnString)
    Dim OleDbDataAdapter1 As System.Data.OleDb.OleDbDataAdapter = New System.Data.OleDb.OleDbDataAdapter(sqlString, OleDBConn1)
    Dim dbGen As New OleDbCommandBuilder(OleDbDataAdapter1)

    Private Sub frmOrder_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'MyDBBackendDataSet3.tblInsuranceClaim' table. You can move, or remove it, as needed.
        Me.TblInsuranceClaimTableAdapter.Fill(Me.MyDBBackendDataSet.tblInsuranceClaim)
        txtPDrug.Text = frmDrugs.txtDrugHidden.Text

        Try
            OleDbDataAdapter1.AcceptChangesDuringUpdate = True
        Catch ex As Exception
            MsgBox("An exception was thrown because the back-end database is currently not allowing updates. Please try again.")
        End Try

        Try
            OleDBConn1.Open()
        Catch ex As Exception
            MsgBox("An exception was thrown because a connection to the database or database tables cannot be established")
        End Try

        TblInsuranceClaimBindingSource.AddNew()
    End Sub

    Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
        Try
            Me.Validate()
            Me.TblInsuranceClaimBindingSource.EndEdit()
            OleDbDataAdapter1.Update(Me.MyDBBackendDataSet.tblInsuranceClaim)
            MyDBBackendDataSet.Tables("tblInsuranceClaim").AcceptChanges()
            OleDbDataAdapter1.Update(MyDBBackendDataSet, "tblInsuranceClaim")
            OleDBConn1.Close()
            MsgBox("Update Successful")
        Catch ex As Exception
            MsgBox("Update Failed")
        End Try
    End Sub

Consider My.Settings to save settings between runtime sessions.  You'll find it in the project properties under the Settings page.

To save you just need something like:

My.Settings.CommandButton = txtCommand.Text

To load you you use the forms load event with:

txtCommand.Text = My.Settings.CommandButton.

Thanks for the reply - but I think you misunderstood my question.
My form has a number of different controls on it, mostly textboxes.  And I want the information that the user types in to be saved into the database when the user clicks the Save command button on the form.

Ah my mistake, to update changes in your binding source controls you'll want to use the data adapters update method.  I see your using an Access DB, here is some specifics:
