How does this actually update the table?

Warning: I am very new to Access coding.开发者_如何学编程 I am used to .NET and PHP

I just converted an Access 95 program to Access 2007 and I got it all working now I am trying to make some updates.

I have a form that updates a table in the database but I can't find an attached query or anywhere where it actually does a SQL statement. Please help. And thank you.

This is all the code on the one form.

    Option Compare Database
`enter code here`Option Explicit
Private Sub Check158_Click()

    ' Try and change sql code
    Me.Combo35.RowSource = "SelectAllOrders"
End Sub

Private Sub Combo35_AfterUpdate()
                                                                                                                                                                                                                            Me.RecordsetClone.FindFirst "[OrderID] = " & Me![Combo35]
    Me.Bookmark = Me.RecordsetClone.Bookmark
    ' Find the record that matches the control.

The form in your first example is likely a databound form - it should have a datasource set, which will be the query or table used to populate the fields on the form. If you edit values on the form, and close the form, it will automatically commit changes to the tables underlying that query.

The second example has some navigation buttons...navigating away from the current record should automatically cause a commit as well. Again, look at the datasource property of the form to work out what it's updating.
