    I am new here and rookie programer.  I am totally lost and cannot find exactly what I am looking for.  Here is my problem.  I have a database (access) and a table for users accounts in the database.  I have a form to edit the user accounts but cannot get it to work properly.  The form has a listbox to the left that displays usernames and then textboxes to the right that contains the information about the user.  I am able to get the usernames to populate in the listbox, but I cannot get the textboxes to display the correct information and be able to update, add or delete users.  Can somebody please help?

    Thats the thing, I dont know exactly how to write it.  Its not that I have an error in the code, I just dont know exactly what I need.  I know I need a connection, dataset, and datadpator.  But I dont know how to sync the textboxes with listbox and the listbox with the database so the information can be updated.

    Here's what you do.  You bind the ListBox to the DataTable so that it displays the user names, e.g.
    myListBox.DisplayMember = "UserName"
    myListBox.ValueMember = "ID"
    myListBox.DataSource = myDataTable

    Now you need to bind the other controls to the same data source, e.g.
    myTextBox1.DataBindings.Add("Text", myDataTable, "FirstName")
    myTextBox2.DataBindings.Add("Text", myDataTable, "LastName")
    This binds the Text properties of the two TextBoxes to the FirstName and LastName columns of the same table to which the ListBox is bound.  That means that when you make a selection in the ListBox the contents of the TextBoxes will be updated to display the corresponding fields.

    Thank you.  So do I need to put any code in the listbox's selectedvaluechanged event?
