This kind of thing does belong in the Form_Load event, as Uncle Gizmo suggested, but if you're trying to get the Combobox to have Focus and dropdown, immediately the Form opens, I'm afraid you're in for a disappointment! I've seen this problem reported for years, on the half-a-dozen Access forums I participate in, have seen many, many approaches tried, and have never seen one that worked! Even if, on opening the Form, you set Focus to another Control, then set it to the Combobox, then drop it down, it still immediately returns to the non-dropped down position...it does drop down (I found this out when testing when my anti-virus software was running, making everything else run slowly) but it immediately rolls back up.
I'd love to see a solution that does work!
