The form it is on is frmMidwest.vb, the database is MarchMadnessDB, with the table being tblMidwest and the column being Username. I am trying to get it so when the user loads frmMidwest.vb it will then check the database to see if the user has entered their picks and if they have it will load their picks back into frmMidwest.vb if the database cannot find their user then it needs to add a record to the database and allow the user to enter their picks. I have already established this with
TblMidwestBindingSource.AddNew()
But if the user exists I do not want them to be able to enter another record. The primary key in the database is the username.

frmAddUser is a simple form that is opened as a dialog by a command button on the primary form (frmPrimary). Once opened, it's only job is to collect information via textbox and combobox fields. Once submitted, the information is added to the database.
This works, or so I thought. If I open this form, fill it out, and submit the information; the record is created. However, if I turn around and do it all again with different information, another record is created but with the previous information (not the new). It will continue to make records as long as I keep submitted this form but no matter what information I put in, it always uses the original information that was used to create the first record.[code]...

I created a small program that reads an access database 2007 I added the database from the data sources window, the fields I created were ID, Name, Transaction, email and Number. where number has a YES index(no duplicates) option. And they all are TEXT types. I created a new form and added the datagrid of the database and want to create a search by number. so I click on the add query, then on the number filter I added LIKE @Number + '%' BUT IT CHANGES TO: LIKE '@Number' + '%' so the query wont work, and VB.net wont create the text field or anything. what is it that I have to do?
