eugeneng, guess what... I have a solution for you utilizing the same APIs that we used to set the borders on your MDI form to fixed. see: http://www.experts-exchange.com/visualbasic/Q.20272107.html

Amend your code as follows in the MDI Form:

'** = changes added since the code I gave you to get fixed borders

Option Explicit
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _
 (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" _
 (ByVal hwnd As Long, ByVal nIndex As Long) As Long

Const GWL_STYLE = (-16)
Const WS_THICKFRAME = &H40000
Const WS_MINIMIZEBOX = &H20000  '**
Const WS_MAXIMIZEBOX = &H10000  '**

Private Sub MDIForm_Load()
Dim CurStyle As Long
Dim NewStyle As Long
Dim L As Long  '**
'This code will remove the min and max boxes from the MDI form
L = GetWindowLong(Me.hwnd, GWL_STYLE) '**
L = L And Not (WS_MINIMIZEBOX) '**
L = L And Not (WS_MAXIMIZEBOX) '**
L = SetWindowLong(Me.hwnd, GWL_STYLE, L) '**
'This code will set the borderstyle = fixed
CurStyle = GetWindowLong(MDIForm1.hwnd, GWL_STYLE)
NewStyle = SetWindowLong(MDIForm1.hwnd, GWL_STYLE, CurStyle And Not (WS_THICKFRAME))
End Sub

I think this will take care of all your woes!

eugeneng - This is better... In my haste I did not look carefully enough at what I was doing.  Use this code instead for your MDIForm load:

Private Sub MDIForm_Load()
Dim CurStyle As Long
Dim NewStyle As Long

CurStyle = GetWindowLong(Me.hwnd, GWL_STYLE)
CurStyle = CurStyle And Not (WS_MINIMIZEBOX)
CurStyle = CurStyle And Not (WS_MAXIMIZEBOX)
CurStyle = CurStyle And Not (WS_THICKFRAME)
NewStyle = SetWindowLong(Me.hwnd, GWL_STYLE, CurStyle)
End Sub

e, you may want to leave this code, provided in the referenced question above in your program:

Private Sub MDIForm_Resize()
Static bMsgd As Boolean
Me.WindowState = vbNormal
If Not bMsgd Then
  MsgBox "You are not allowed to resize this window!"
  bMsgd = True
Else
  bMsgd = False
End If
End Sub

The reason is... if you click on the upper left icon of the MDI Form, you STILL have Min & Max options there!  Inclusion of this code will override those if the user discovers them.

E,
To get rid of the close button and the icon dropdown you can add this constant like so:

Const WS_SYSMENU = &H80000

Private Sub MDIForm_Load()
Dim CurStyle As Long
Dim NewStyle As Long
CurStyle = GetWindowLong(Me.hwnd, GWL_STYLE)
CurStyle = CurStyle And Not (WS_MINIMIZEBOX)
CurStyle = CurStyle And Not (WS_MAXIMIZEBOX)
CurStyle = CurStyle And Not (WS_THICKFRAME)
CurStyle = CurStyle And Not (WS_SYSMENU)
NewStyle = SetWindowLong(Me.hwnd, GWL_STYLE, CurStyle)

Then you can rely on your form menu for an exit...  I
