Access的窗体貌似还不是DirectUI,而可能是“Microsoft Forms 2.0”。不过我也不确定,下面是今天碰巧看到的一段话:
Differences between the "Microsoft Visual Basic 6.0 Extensibility" and "Microsoft Visual Basic for Applications Extensibility 5.3" extensibility models. The most noticeable difference is that the former provides the VBForm and VBControl classes while the latter uses the separate "Microsoft Forms 2.0 Object Library" component for that functionality, which is quite different.
