AndAlso/OrElse in VBA

The only short circuiting (of a sort) is within Case expression evaluation, so the following ungainly statement does what I think you’re asking;

Select Case True
    Case (myObject Is Nothing), Not myObject.test()
        MsgBox "no instance or test == false"
    Case Else
        MsgBox "got instance & test == true"
    End Select
End Sub
