#1979 closed Bug (No Bug)

_WinAPI_SetWindowsHookEx() Don`t work with all idHook

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


_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.

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6

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

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


Func _Main()

	Local $hmod

	$hStub_CallWndRetProc = DllCallbackRegister("_CallWndRetProc", "long", "int;wparam;lparam")
	$hmod = _WinAPI_GetModuleHandle(0)
	$hHook = _WinAPI_SetWindowsHookEx($WH_CALLWNDPROCRET, DllCallbackGetPtr($hStub_CallWndRetProc), $hmod)
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $hHook = ' & $hHook & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console

	While 1
EndFunc   ;==>_Main

; callback function

	local $tagCWPRETSTRUCT = "LRESULT lResult;LPARAM lParam;WPARAM wParam;UINT message;HWND hwnd;"
	Local $tCWPRETSTRUCT = DllStructCreate($tagCWPRETSTRUCT, $lParam)
	If $nCode < 0 Then
		Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
	If DllStructGetData($tCWPRETSTRUCT, "message") = $WM_MOUSEMOVE Then
		ConsoleWrite("Mouse Move Message Recived by - " & DllStructGetData($tCWPRETSTRUCT, "hwnd") & @CRLF)
	Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
