If you create a bitmap file and store it in the same folder as your databse
and name it the same as your database (with the extension .bmp) then it will
replace the Access splash screen.
Other wise, you'd need to create a form. Have is open on startup (use the
Tools/Startup). Add code in the form's timer event to close after a set
anmount of time. Or allow the user to close it with a button.
