_WinAPI_SetWindowsHookEx() Don`t work with all idHook

Reported by: monoscout999 Owned by: Gary
Milestone: Component: Standard UDFs
Version: 3.3.6.1 Severity: None
Keywords: Hooks, Hook Cc:

Description

_WinAPI_SetWindowsHookEx() only works when the idHook parameter is $WH_KEYBOARD_LL or $WH_MOUSE_LL and not when the idHook parameter is another as $WH_CALLWNDPROCRET for example.

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <StructureConstants.au3>

Global $hHook, $hStub_CallWndRetProc, $buffer = ""

	$hHook = _WinAPI_SetWindowsHookEx($WH_CALLWNDPROCRET, DllCallbackGetPtr($hStub_CallWndRetProc), $hmod)
