Hi there,

I have an app on an NT4 box, if a user clicks the X top right corner to close, and not using the correct exit button in the app, the database corrupts.

Any Ideas?

You can compile the following script as "StartNoClose" using AutoIT (
Then run your application through StartNoClose:
StartNoClose.exe "C:\Programe Files\Acme\acme.exe"
Note that you'll need the version for this to work on NT4.


Skript for AutoIT (

Starts the program passed as argument in the command line, and removes "Close" from the system menu;

this will disable the windows's "X" button as well, but it will not disable Alt-F4.

Tested and compiled with AutoIT v3.2.12.1; use Aut2exe.exe to compile this script into an executable.


AutoItSetOption("TrayIconHide", 1)

Global Const $SC_CLOSE = 0xF060

Global Const $MF_BYCOMMAND = 0x0

Func _ParseCommandLine(ByRef $strRunProgram)

Local $i

	If $CmdLine[0] = 0 Then

		$Syntax = @ScriptName & @CRLF & _

			"Starts the program passed as argument and disables the system 'Close' menu." & @CRLF & _

			@CRLF & _

			"Syntax: " & _

			@ScriptName & " <Program>"

		MsgBox(0 + 32, @ScriptName & " Syntax", $Syntax)



		$strRunProgram = $CmdLineRaw



Func _GetHwndFromPID($PID)

Local $hWnd

Local $stPID

    $hWnd = 0

    $stPID = DllStructCreate("int")


        $winlist2 = WinList()

        For $i = 1 To $winlist2[0][0]

            If $winlist2[$i][0] <> "" Then

                DllCall("user32.dll", "int", "GetWindowThreadProcessId", "hwnd", $winlist2[$i][1], "ptr", DllStructGetPtr($stPID))

                If DllStructGetData($stPID, 1) = $PID Then

                    $hWnd = $winlist2[$i][1]






    Until $hWnd <> 0

    Return $hWnd

EndFunc ;==>_GetHwndFromPID

Func _RemoveClose($hWnd)

Local $ret

Local $hSystemMenu

	$ret = DllCall("user32.dll", "int_ptr", "GetSystemMenu", "hwnd", $hWnd, "int", 0)

	$hSystemMenu = $ret[0]

	DllCall("user32.dll", "int", "DeleteMenu", "hwnd", $hSystemMenu, "uint", $SC_CLOSE, "uint", $MF_BYCOMMAND)


Func _Main()

Local $intPid

Local $hWnd

Local $strRunProgram


;	When doing test runs out of SciTE, set $strRunProgram to the program you want to start; $CmdLineRaw will contain arguments

;	$strRunProgram = "calc.exe"

	$intPid = Run($strRunProgram)

	If ($intPid = 0) Then

		MsgBox(0 + 48, "Error", "Program not found: " & @CRLF & $strRunProgram)



		$hWnd = _GetHwndFromPID($intPid)
