在网上找了下面的代码,在VB中能成功拉伸窗体,请求高手指点怎么把它用在access中来!!!!!急
Option Explicit
Private Const WM_NCLBUTTONDOWN = &HA1
Private Const HTLEFT = 10
Private Const HTRIGHT = 11
Private Const HTTOP = 12
Private Const HTBOTTOM = 15
Private Const HTBOTTOMRIGHT = 17
Private Const HTBOTTOMLEFT = 16
Private Const HTTOPLEFT = 13
Private Const HTTOPRIGHT = 14
