此方法须把启动窗口设置为弹出属性。所以不适用所有的数据库。其方法是在启动窗体的加载属性中加入如下代码

DoCmd.RunCommand acCmdAppMinimize'最小化ACCESS窗体

方法二------------------------------
1、定义以下变量
Option Compare Database
Option Explicit
Private Declare Function ShowCursor Lib "user32" (ByVal bShow As Long) As Long

Const WM_SYSCOMMAND As Long = &H112
Const SC_MOVE_MOUSE As Long = &HF012&
Private Declare Function ShowWindow Lib "user32" _
  (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
2、在启动窗体中键入以下代码并把启动窗体的弹出属性设为是
Private Sub Form_Load()
ShowWindow Me.Application.hWndAccessApp, 0

End Sub


要隐藏数据库窗口，使用以下代码：
DoCmd.SelectObject acForm, "你的窗体名", True
DoCmd.RunCommand acCmdWindowHide



要最小化数据库窗口，使用以下代码：
DoCmd.SelectObject acForm, , True
DoCmd.Minimize
