array assigned to DllCall() returns negative integer

Hi all,

I am trying to help my brother with a project of his and am having a problem with DllCall().

The variable its assigned to returns an array limit of -2147024809.

The code is:

_SetColor()
Exit

Func _SetColor()
    Local $result
    ConsoleWrite("In Function")
    Local $return = DLLCall(@Systemdir & "\dwmapi.dll", "int", "DwmIsCompositionEnabled", "int", "pfEnabled")
    ConsoleWrite($return[0])
    return $return
EndFunc   ;==> _SetColor

Does anyone have any idea what may be up with this code?

Thanks,

shanet

Furthermore, if I remove the first parameter, it freezes then returns -1073741819

nvm just figured it out :unsure:

_SetColor()
Exit

Func _SetColor()
    Local $result
    ConsoleWrite("In Function")
    Local $return = DLLCall(@Systemdir & "\dwmapi.dll", "BOOLEAN", "DwmIsCompositionEnabled", "BOOL", "pfEnabled")
    ConsoleWrite($return[0])
    return $return
EndFunc   ;==> _SetColor

nvm just figured it out :>

_SetColor()
Exit

Func _SetColor()
    Local $result
    ConsoleWrite("In Function")
    Local $return = DLLCall(@Systemdir & "\dwmapi.dll", "BOOLEAN", "DwmIsCompositionEnabled", "BOOL", "pfEnabled")
    ConsoleWrite($return[0])
    return $return
EndFunc   ;==> _SetColor

Figured out what? How to call it wrong? :unsure:

You can't pass a string to a parameter that expects an int. AutoIt should be failing there...
