How can I tell if a form (other than the one I'm working on) is open or closed?

You must distinguish between Loaded and Visible .

For visiblility, just check the property Visible

(noting that doing this for an unloaded form will load it).

Unfortunately, there is no property for the loading state. You have to loop over all the forms and see if your form is contained in the list of loaded forms:

Public Function IsFormLoaded(FormToCheck As Form) As Boolean
  Dim F As Form 
  For Each F In Forms
    If F Is FormToCheck Then
      IsFormLoaded = True
      Exit Sub
    End If
  Next
End Sub

The global collection Forms

contains all currently loaded forms.

You can search the collection of forms

Dim aForm
For Each aForm In Forms
  If aForm Is Form1 Then
    MsgBox "Found Form1"
  End If
Next

If the form is in your application, you can just keep track of its internal state. After all ... you control the points in your code when they can be created or destroyed.
