In the comments from Z_Beeblebrox, in question
http://www.experts-exchange.com/questions/Q.20195631.html,
he refers to a link where you can inactivate the "X" (close) button in an application. (
http://www.allapi.net/tips/tip060.SHTML).
I tried this for other running applications, and it works.
But now the user can still use the "Close" and "exit" from the "File" menu.
How can I suppres or inactivate this options????

Private Declare Function RemoveMenu Lib "user32" (ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long) As Long

Private Sub Form_Load()
Dim hSysMenu As Long, nCnt As Long
' Get handle to our form's system menu
' (Restore, Maximize, Move, close etc.)
hSysMenu = GetSystemMenu(Me.hwnd, False)
If hSysMenu Then
' Get System menu's menu count
nCnt = GetMenuItemCount(hSysMenu)
If nCnt Then
' Menu count is based on 0 (0, 1, 2, 3...)
RemoveMenu hSysMenu, nCnt - 1, MF_BYPOSITION Or MF_REMOVE
RemoveMenu hSysMenu, nCnt - 2, MF_BYPOSITION Or MF_REMOVE ' Remove the seperator
DrawMenuBar Me.hwnd
' Force caption bar's refresh. Disabling X button
Me.Caption = "Try to close me!"
