I have a sub that is activated after losing focus from a field: the user scans in a barcode and the scanner automatically tabs forward, running the sub.

I want to end the sub by clearing and setting the focus to the original field, but it won't let me: I presume this is because you can't set the focus in a sub that loses the focus.

Is there a 'nice' way to do this? Maybe activate the sub differently?

At the end of your sub, you should be able to set the focus to any text box and then reset it's value.

Me.TextBox1.SetFocus
Me.TextBox1.Value = Null

But do you need to move to a new record so that you do not remove what was just scanned in the current record?
