Do you have any code in the Listview's events that may be raising this error?  Check your events for the Listview and step through them in debug.

Is the form which it resides on visible at the moment of setting focus ? It must be, or "Invalid procedure call or argument" will occur.

the listview and the form must be visible and enabled before setting focus to it.
What does it mean to be "Always On"?

I think that definately ur enabled property of the list view is False.  Make it true and try again.

This usually happens when you call SetFocus() on the Form_Load, where the destination object (i.e. the one you are trying to setfocus) is not yet visible.
If this is the case, you can use the Form_Activate event, or you can use On Error Resume Next.
Hope this helps you.
