With OpenFileDialog
.Title = "Choose a image"

Ive only recently starting fiddling with Visual Basic Express and Sql Databases. Ive managed to get a database up and running, and can query information from it. I have even created a form that can add a new entry to the table im using.The first form has a ComboBox that list the PlayerNames in my table. Form2 allows you to add a new name to the table, but anything I add isnt immediately updated in Form1. I have to relaunch the program to see the new entries. Even then, these new entries dont seem to be permanent as they eventually dissappear.The code I have for Form1:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

The problem has been simplified for the purpose of clarity. I want to make a windows form application that uses an access database. The application will store the list of person's basic details such as name, age and country. The database contains two related tables ie person(id, name, age, country_id) and country(id, country_name) My windows form contains TextBox, DateTimePicker, ComboBox for Name, Age and Country respectively. Now I want to make CRUD operation Programmatically (Not using Visual tools) in the same form with some navigation buttons.
