EDIT
My prior answer was completely and totally wrong. I misread the question, and apologize. (This is the downside of hitting these sites before my morning caffeine!)
Not all Access databases will have code. However, you don't need code to get your databases to display this behavior.
- Open the database you wish to create a startup form for in Microsoft Access.
- Click the Microsoft Office button in the upper left of the Access window.
- Click the "Current Database" option on the left side of the Options window that comes up.
- Select the form you wish to use at startup from the "Display Form" box.
- Scroll down, and uncheck the following boxes:
- "Display Navigation Pane" This turns off the left-hand bar.
- "Allow Full Menus"
- "Allow Default Shortcut Menus"
- "Allow Built-In Toolbars"
Of course, all this is predicated on having a form for startup. Also, once you do this, you will need to start up the database holding down the SHIFT key to make changes to it.
