DllCall doesn't output error but doesn't work

[careca]

Hey guys, the code under works, but i have the very same code embedded in another script, and what happens is that it doesn't retrieve any error, but it doesn't move/retract the window.

Wonder what can be conflicting with it.

PS: If i have a sleep and then the call, it works, but that is not what i need.

@error is always 0

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
AdlibRegister('Retract', 2000)
Local $SlideType3 = 0x00040008 ; $AW_SLIDE_IN_BOTTOM
Local $SlideType4 = 0x00050004 ; $AW_SLIDE_OUT_BOTTOM
Local $hGUI = GUICreate("", 400, 100, @DesktopWidth - 401, @DesktopHeight - 101, BitOR($WS_POPUP, $WS_BORDER), $WS_EX_TOPMOST)
DllCall("user32.dll", "int", "AnimateWindow", "hwnd", $hGUI, "int", 800, "long", $SlideType3)
GUISetState(@SW_SHOWNA, $hGUI)

Func Retract()
DllCall("user32.dll", "int", "AnimateWindow", "hwnd", $hGUI, "int", 600, "long", $SlideType4)
Sleep(2000)
Exit
EndFunc

While 1
    Sleep(100)
WEnd

See "_WinAPI_AnimateWindow" function in help file for parameters, and in the include file "WinAPISys.au3" for the working DllCall().

Well, im sorry to say, but that doesn't help, the call is the same as mine, and the results are the same, the issue in not in the parameters of the call, it's something else, i was hoping someone has gone thru this issue that could pinpoint what could be the cause.

EDIT:

_WinAPI_GetLastError() says 1400.

As in MSDN:

ERROR_INVALID_WINDOW_HANDLE

Invalid window handle.1400 (0x578)

So how come it's valid going up, and not valid to go down?

Perhaps your variables aren't global in your real script? 

[careca]

That's right, they're local, think that has to do with it? then if so, how come the first call works?

Will look into that when i get to the pc.

Considering I have no idea what your real script looks like, I'd have absolutely no idea where the problem might be. I was thinking that your real script has the gui creation inside a function, and you're using another function to retract the window. But it was a guess, nothing more.
