[ANGanley]

Can anyone help me this?

I have a class.

Public Class db_Vehicle
 
    Public bs_VehicleDetails As New BindingSource()
    Public da_VehicleDetails As New SqlDataAdapter()
    Public table As New DataTable()
 
    Private dbsettings As cls_settings
 
    Public Sub New(ByRef mySettings As cls_settings)
        Me.dbsettings = mySettings
    End Sub
 
    Public Function GetVehicleDetails() As BindingSource
 
            'Dim ds As DataSet
            Dim dsChanges As New DataSet
 
            ' Specify a connection string.
            Dim dbcnn As SqlConnection = New SqlConnection(dbsettings.getDatabaseString)
 
            ' Create a new data adapter based on the specified query.
            Me.da_VehicleDetails = New SqlDataAdapter("SELECT ServiceFlag FROM ServiceDates", dbcnn)
 
            ' Create a command builder to generate SQL update, insert, and
            ' delete commands based on selectCommand. These are used to
            ' update the database.
            Dim commandBuilder As New SqlCommandBuilder(Me.da_VehicleDetails)
 
            ' Populate a new data table and bind it to the BindingSource.
            table.Locale = System.Globalization.CultureInfo.InvariantCulture
            Me.da_VehicleDetails.Fill(table)
            Me.bs_VehicleDetails.DataSource = table
 
            'Newform.dgv_Vehicles.DataSource = bs_VehicleDetails
            Me.da_VehicleDetails.Update(table)
 
 
 
        Return bs_VehicleDetails
 
    End Function
 
End Class

Then I call my class.

Public Sub Retrieve_SF()
 
        Dim imageNo As Image = System.Drawing.Image.FromFile("C:\Development\Image\Red.bmp")
        Dim imageYes As Image = System.Drawing.Image.FromFile("C:\Development\Image\Green.bmp")
 
        Dim dgvICol As New DataGridViewImageColumn()
        Dim Conn_SF As SqlClient.SqlConnection = New SqlClient.SqlConnection(dbsettings.getDatabaseString)
        Dim command As SqlCommand = New SqlCommand("SELECT ServiceFlag FROM ServiceDates", Conn_SF)
 
        'Dim instance As New DataGridViewRowCollection
        'Dim dataGridViewRow As New DataGridViewRow
        'Dim returnValue As Integer
 
        Conn_SF.Open()
 
        dgvICol.HeaderText = "Service Flag"
        dgvICol.Name = "ImageCol"
 
        Dim reader As SqlDataReader = command.ExecuteReader()
 
        dgv_Vehicles.Columns.Insert(0, dgvICol)
        'dgv_Vehicles.AllowUserToAddRows = True
 
        Dim i As Integer = 0
 
        'This is to temporarily store the results of the reader.read method
 
        Dim strItem As String
 
        While reader.Read()
            With dgv_Vehicles
 
                '.EditMode.EditProgrammatically = DataGridViewEditMode.EditProgrammatically
                .EditMode = DataGridViewEditMode.EditProgrammatically
 
                Dim rw As New DataGridViewRow
                'Dim dradd As New DataRow
 
                rw.Cells.Add(New DataGridViewImageCell)
                strItem = reader.Item(0).ToString
                If reader.HasRows Then
 
                    i += 1
 
                    strItem = strItem.TrimEnd(" ")
 
                    If strItem = "Out" Then
                        rw.Cells(0).Value = imageNo
 
                    ElseIf strItem = "In" Then
                        rw.Cells(0).Value = imageYes
 
                    End If
 
                    '.DataSource = DBNull.Value
                    'Vehicle.bs_VehicleDetails.Add(rw)
                    .Rows.Add(rw) "Error here"
                    'returnValue = instance.Add(dataGridViewRow)
 
                    .AutoResizeColumn(0)
                    'This clears the variable
 
                    strItem = ""
 
                End If
            End With
        End While
 
    End Sub

When I try & add my row I get the error. I've tried loads of different things but can't get it to work.
