I created a access table with three fields, CustomerID, FirstName, LastNameI set the CustomerID field to the primary key and the type of AutonumberIn my VB app I dragged the three fields over to my form.I clicked on the plus sign at the top and it displayed -1 in the customer field, I entered a First Name and a Last Name and press the save button. I repeated the process 2 more times and the CustomerID field went from -2 to -3.I looked at my table in acces and all three records showed 1, 2 & 3 as it should. When I exited the form and then open the form again it shows record numbers 1, 2 & 3 as it should.How come it takes exiting the form and then back in to see the correct CustomerID's ?

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.
I am using vb to make a hospital system which works with a access database. i am having an issue with the updating function to the database, this time round instead of hard codding the connection i used the connection/data source wizard, in microsoft visual studio 2008 and there fore most of the code has been auto generated for me, which includes the insert, delete and update funtions from what i can find and what i have read vb is ment to also auto generate this which it is not. the funny thing is that i can close the program down and reload it (as long as i haven't opened the database) and my changes are still there but if i go and open the database and it hasn't changed. also i can change the database through the use of the Dataset connections in the datasource tab but not int he program the code ive found and believe that is meant to update the database
This is running off a couple of buttons i also have a update query but have know way of accessing it

Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.
