Phumlani · November 28th, 2011, 03:22 AM

HI Guys

I would like to ask if I need to call a dll com object do I have to
refer to it as ActiveXObject or I can just call it like :
new com("Soundclass.Soundrec");

I would appreciate your answer soon pls thanks.

also I have a problem where I inherit a com object from a dll file like so:

<?

$test = new com("Soundclass.Soundrec");
$test->startrec;
$test->stoprec;

?>

in php I was wondering if is it possible to do this in javascript and how can I do it pls guys provide code samples if you can I as I am a javascript newbie thanks

If the DLL supports being called from script then you need:

Code:

var recorder = new ActiveXObject("Soundclass.Soundrec");
recorder.startRec();

This will only work on Internet Explorer and only if the user has allowed ActiveX to run. (There are two settings, one for safe ActiveX and another for unsafe ActiveX. Most users allow safe ones by default but I imagine that this control if unsafe so would only be suitable for an intranet scenario where you have some degree of control over the settings.)

Hi Joe

Thank you for your reply, so I have to write this code on the head of the file as I am using zend or can I put this code on the body?

Hi Joe

I have tried using your example and nothing happens here is the example of how I tested it please advise
"<script type="text/javascript">
var test = new ActiveXObject("Soundclass.Soundrec");
test.startRec ();
setTimeout("test.stoprec()",5000);
</script>
"

As I have no idea what should happen it's hard to tell. Unfortunately newer versions of IE hide error messages so, if you're using IE9, then you need to run the developer tools (F12 usually) and see what's going on.
Did you allow unsafe controls in your browser? Does the controls support the IQueryable interface?

Hey Joe

Just a thought is possible that I can invoke the stop code on the php code I have provided above?

No, PHP code runs on the server, JavaScript runs in the browser.
