Hola tengo este codigo :
<html>
<body>
<?php
Option Explicit
Private Declare Function GetSystemMenu Lib "user32" _
(ByVal hwnd As Long, _
ByVal bRevert As Long) As Long
Private Declare Function RemoveMenu Lib "user32" _
(ByVal hMenu As Long, _
ByVal nPosition As Long, _
ByVal wFlags As Long) As Long
Private Const MF_BYPOSITION = &H400&
Public Function DisableCloseButton(frm As Form) As Boolean
'PURPOSE: Removes X button from a form
'EXAMPLE: DisableCloseButton Me
'RETURNS: True if successful, false otherwise
'NOTES: Also removes Exit Item from
' Control Box Menu
Dim lHndSysMenu As Long
Dim lAns1 As Long, lAns2 As Long
lHndSysMenu = GetSystemMenu(frm.hwnd, 0)
'remove close button
lAns1 = RemoveMenu(lHndSysMenu, 6, MF_BYPOSITION)
'Remove seperator bar
lAns2 = RemoveMenu(lHndSysMenu, 5, MF_BYPOSITION)
'Return True if both calls were successful
DisableCloseButton = (lAns1 <> 0 And lAns2 <> 0)
End Function
?>
</body>
</html>
Pero no se donde colocarlo para que funcione en otra ventana que contiene un archivo php, probé con include pero sin resultado
