COM Pointer

[MISIIM]

I have a method of a COM object that needs to accept a pointer. (This is an iTunes hotkey program.) How would I do this or is it not possible?

Func VolUp()

Local $volume = DllStructCreate("long");

$itunes.SoundVolume(DllStructGetPtr($volume, 1));

Dim $newvol = DllStructGetData($volume, 1) + 10;

If $newvol > 100 Then $newvol = 100;

MsgBox(0, "", $newvol);

$itunes.SoundVolume($newvol);

$volume = 0;

EndFunc

I don't see the need for a pointer. Take a look at this program, it uses iTunes COM extensively and is commented fairly well.

Thank you. I guess SoundVolume should be used like a property.

Your welcome. Yes it would be something like...

$iVolume = $oiTunes.SoundVolume; retrieve the current volume
$oiTunes.SoundVolume = 50; set the volume
