I'm creating a rewards system for school where pupil earn points for good behavior which they can then use to purchase things like a packet of pens. (They can also have points deducted for bad behavior). I've created all the forms and now its just getting the data in from the Access database. This is what I need to do. On my form called detailsPupil it shows various information such as Name, email address, last login etc. This form is loaded once the pupil has logged in.
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
Dim Login = Me.StudentTableAdapter1.UsernamePasswordString(txtUsername.Text, txtPassword.Text, cboPermissions.Text)
If Login Is Nothing Then
MsgBox("Incorrect Username or Password")
[Code] .....
That all works but I'm having problems working out how to get the information like Name and email address into their places. This is what I have so far on my detailsPupil form.
Public Class detailsPupil
Private Sub btnLogOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogOut.Click
Login.Show()
[Code] .....
So to sum up I need to run a query which searches the DB using the Username which is obtained from the login form and then displays the Student Name in txtName, Email address in txtEmail etc...

I am using Visual Studio 2005 (Visual Basic) and MS Access 2003 I am trying to build an application in the lines of the book "Doing Objects in Visual Basic 2005" by Deborah Kurata. So, I have a Data Access Layer (DAL) Class Library that is separated from the business logic layer (business objects) Class Library. I try to add a new business object such as a "Customer" to the Access Database, where the "Customer" table has a PrimaryKey "CustomerID" which is an AutoNumber field. I am successful in writing the values to the database, but I can't figure out how to know the "CustomerID" of a newly added "Customer" so I can populate the business object with the respective values.
