hw do I call a dlll function in javascript?

[Charles Prince]

Not had much to do with windows so am struggling a bit (lot) here.

Our server applications build a html form then send that form to the
clients browser. Standard stuff here.

Now I need to embed a 3rd party tool which presents the user with choices
and passes the results back to the caller. The authours assure me that
their tool is fully "DD" compliant so can be called by any other "DD"
compliant application.

So using javascript running in the cloient browser, I need to ba able to
load a client side dll in to the browser form and then call the dll'd
functions.

Can anyone tell me a simplistic method of loading a client side dll and
using it's functions please?

TIA.

Hi,

What is "'DD' compliant"?

Loading a client-side DLL is now allowed in JavaScript. If you are
talking about a plug-inn or a trusted active X component then
there might be hope.

Thanks,
Vincent

Complies with Microsoft's dynamic data exchange interface which I am told
that they have based their active X technology on.

So given that I am completely new to this, how would I go about loading
the dll in order to use it's functions.

All documentation and references I have found to doing this are all
related to server side dll's but I want to integrate a client side dll.

Well, what you need to do is somehow load it with ActiveX:

myComp = new ActiveXObject(" server.type","l ocation");

See:

http://msdn.microsoft.com/library/en-us/script56/html/js56jsobjActiveXObject.asp

http://msdn.microsoft.com/library/en-us/script56/html/js56jsfctgetobject.asp

Then you can call it with myComp.myfuncti on(...) etc...

The following code shows the version of Excel installed on your
computer, notice the secutiry warning if you load it from a
website:

<script language="JavaS cript">
try {
var XLApp = new ActiveXObject(" Excel.Applicati on");
alert(XLApp.Ver sion);
} catch (e) {
alert("error: "+e.message );
}
</script>

Good luck,
Vincent

I noticed that loading an untrusted activeX object only works
in one of the following ways:

- when you add that site to your trusted sites
(internet options -> security -> trusted sites
uncheck the 'https' thing and add your site)
- load it from a trusted HTML application (HTA)
- when the component itself is signed/trusted

Good luck,
Vincent

Hey Vincent, I've been away for a couple of days so did not see your
replies.

Thanks for all the information, I'll give this a try and see if I get it
to work.

Again, thanks very much for you help.
