Hi everyone,
I have also just come across this problem.

I have been using pocket cortona for a few years now and I developed a 3D world with lots of objects in it that link to external html web pages. The url's are set up using the VRML automation. This has always worked fine on my PDA (HP iPAQ h3970).

However, I recently got a new PDA (HP iPAQ hx2700) and I have tried to run the same 3D world on it. Now the links to external web pages do not work. Is there any reason why they wouldn't work on my new PDA when they worked fine on the old one?
I have tried making a simple VRML file with an anchor node in it but it does not work, even when I set up the url through the automation. I have also tried to use the onAnchor event as described in the last message but this did not work either.

Has anyone any ideas how to fix this?

Thanks in advance,
Teresa


I found that the anchor tag didn't work on when I ported to my mobile device (Pocket Cortona 1.5 on PocketPC 2003) so I contacted the Cortona development team. I received the following response...

We are sorry, but this feature does not work in Pocket Cortona (it's a bug).

Best regards,

I've found a workround and guess I'm not alone in wanted to use this, so am releasing it to the community.

1. Make sure you reference your VRML '.wrl' file via an HTML page using the OBJECT tag.
2. Override the native 'onAnchor' event using the SCRIPT tag.

The following example shows the HTML page with an 'embedded' VRML file called anchor.wrl (which uses the anchor tag in the normal way).

--------- example anchor node html file ---------
<html>
<head>
<title>Anchor node example</title>
    <script for="Cortona" event="OnAnchor(Url, Parameter, Description, Name)" language="JavaScript">
    window.location=Url;
    </script>        
</head>
<body>
<table border="0" width="100%" height="100%">
    <tr>
    <td>
    <object ID="Cortona" TYPE="application/x-oleobject"
        CLASSID="CLSID:86A88967-7A20-11D2-8EDA-00600818EDB1" WIDTH="240" HEIGHT="240">
    <param name="Scene" value="anchor.wrl">
    </object>
    </td>
    </tr>
</table>
</body>
</html>
--------- example ends ---------

All of this begs the question of the ParallelGraphics support team - when will the anchor node bug be fixed and a new version be released? I assume you will be provided either a patch or a free upgrade for existing customers?

Best regards
