ACC2000: Maximized Form Shows Control Box and Minimize, Maximize, and Restore Buttons (210299)

RESOLUTION

You can use the following technique to simulate maximizing a window by sizing it as large as possible in the restored, windowed (non-maximized), state.

The following example demonstrates how to create and use a sample Sub procedure called MaximizeRestoredForm to restore a form if it is maximized, and then to move it to the upper-left corner of the Microsoft Access client area window and to size it as large as possible.

NOTE: This technique produces a blank section at the top of the form that is approximately the height and width of a toolbar if the form is opened in Design view and then switched to Form view. This code works best when the form is opened from the Database window or through code while running the application.

1. Create a new module and type the following lines in the Declarations section:

   Type Rect
      x1 As Long
      y1 As Long
      x2 As Long
      y2 As Long
   End Type
   
   Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, _
      lpRect As Rect) As Long
   Declare Function IsZoomed Lib "user32" (ByVal hwnd As Long) As Long
   Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal _
      nCmdShow As Long) As Long
   Declare Function MoveWindow Lib "user32" (ByVal hwnd As Long, ByVal _
      X As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight _
      As Long, ByVal bRepaint As Long) As Long
   Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long
   
   Public Const SW_MAXIMIZE = 3
   Public Const SW_SHOWNORMAL = 1
   					

2. Type the following Sub procedure in the module:

   Sub MaximizeRestoredForm (F As Form)
      Dim MDIRect As Rect
   
      ' If the form is maximized, restore it.
      If IsZoomed(F.hWnd) <> 0 Then
         ShowWindow F.hWnd, SW_SHOWNORMAL
      End If
   
      ' Get the screen coordinates and window size of the
      ' MDIClient window.
      GetWindowRect GetParent(F.hWnd), MDIRect
   
         ' Move the form to the upper left corner of the MDIClient
         ' window (0,0) and size it to the same size as the
         ' MDIClient window.
         MoveWindow F.hWnd, 0, 0, MDIRect.x2 - MDIRect.x1 + 4, _
            MDIRect.y2 - MDIRect.y1 + 4, True
   End Sub
   					

3. To simulate maximizing a form automatically when it is opened, set the OnLoad property of the form to the following event procedure:

   Sub Form_Load()
      MaximizeRestoredForm Me
   End Sub
   					

4. To simulate maximizing a form called MyForm, use the following statement in a function or subroutine:

   MaximizeRestoredForm Forms!MyForm
