    Dim con As New SqlConnection("Data Source=Tarun-PC;Initial Catalog=couriermanagementsystem;Integrated Security=True")
    Private da As SqlDataAdapter
    Private dt As DataTable
    Private ds As DataSet

        'Calling this method for execution whrn form loads
        LoadRecord()
    End Sub
    
    'This method calls values from database put in datagridview  

    ' Actually you have to Focus on this part only
    Private Sub LoadRecord()

        cmdselect = "select ID,Name,Gender,Position from tblcouriercompany"
        da = New SqlDataAdapter(cmdselect, con)
