Form.Refresh (Access)

The Refresh method immediately updates the records in the underlying record source for a specified form or datasheet to reflect changes made to the data by you and other users in a multiuser environment.

Using the Refresh method is equivalent to choosing Refresh on the Home tab. Microsoft Access refreshes records automatically, based on the Refresh Interval setting on the Advanced tab of the Access Options dialog box, available by choosing the Microsoft Office button, and then choosing Access Options. ODBC data sources are refreshed based on the ODBC Refresh Interval setting on the Advanced tab of the Access Options dialog box. You can use the Refresh method to view changes that have been made to the current set of records in a form or datasheet since the record source underlying the form or datasheet was last refreshed. In an Access database, the Refresh method shows only changes made to records in the current set. Because the Refresh method doesn't actually requery the database, the current set won't include records that have been added or exclude records that have been deleted since the database was last requeried, nor will it exclude records that no longer satisfy the criteria of the query or filter. To requery the database, use the Requery method. When the record source for a form is requeried, the current set of records will accurately reflect all data in the record source. In an Access project (.adp), the Refresh method requeries the database and displays any new or changed records or removes deleted records from the table on which the form is based. The form is also updated to display records based on any changes to the Filter property of the form.
