Me.OpenFileDialog1.Filter = "Ficheiros de imagens (*.jpg)|*.jpg|Todos (*.*)|*.*"

I am creating a feature in my application that will allow a logged in user to add additional users to be logged in. The usernames and passwords are kept in a single database created in Access 2007. The table has 3 columns: ID, UserName, and Password. I am trying to insert user-inputted data through a TableAdapter function in a DataSet. It has worked once but for some reason it stopped working, and I can't figure out why.
Calling the TableAdapter function...
Me.UsersTableAdapter1.AddUser(Me.txtID.Text, Me.txtUsername.Text, Me.txtPassword.Text)
[Code].....
Visual Studio isn't throwing any errors my way or anything so I am not sure what's going on here. The fact that the code worked once but isn't working now is also confusing, and I don't recall making any changes related to this feature since it worked that one time.
I am using this code for my project. What I am not sure is that when I search on the net, they use the "@id" for the insert statement.[code]...

Using a sqlcommand is it possible to use subqueries in an INSERT statement? I attempted the following (and numerous variations playing around with syntax):-
Using insertuser As New SqlCommand("INSERT INTO Users (UserID, Name, Password, Phone) " _
+ "VALUES((Select MAX(UserId)+1 as UserId FROM Users), @name, @password, @phone)", conn)
Errors with 1046: Subqueries are not allowed in this contect. Only scalar expressions are allowed. The scenrio is the userID is hidden from the user and does not appear on the form, I want to find the last value (MAX) userId (integer) and increment by 1. Errorcode 1046 suggests I can't but was wondering if it can be done but was going the wrong way about it.
