You can create a Macro named "autoexec" that contains the operation "OpenForm" and the name of your form. For example, if you want the DB to open a form called "Menu" when you start, go to "Macros" and select "new". Under "action", select "OpenForm". Under "Form Name", select "Menu (or whatever your form's name is). Then save the Macro as "autoexec". The Autoexec Macro will run every time you open the database.
