Hi,

I want to use activex event in javascript.
Here is my htm:

<HTML>
<HEAD>
<TITLE>Scriptable ActiveX Web Control</TITLE>
</HEAD>
<BODY>
<script for=ATLEvent event=ExecutionOver(result) language="Javascript">
alert(result);
</script>
<OBJECT ID="ATLEvent" CLASSID="CLSID:5B898DEC-8172-4B6D-BF1C-FCEF7B517090">
</OBJECT>
</BODY>
</HTML>
<SCRIPT LANGUAGE="JavaScript">
ATLEvent.Add(1, 2);
</SCRIPT>

The activex is simple. It's an atl com dll project. It has an interface
named IXMath and an implemented connect point. The activex project was
downloaded from http://www.codeproject.com/KB/atl/ConnectionPoint.aspx .

I have searched many internet titles. I can't find what's the mistake.
Please let me know where is the mistake.

Thanks in advanced.

So, what exactly is the problem? You never actually mentioned that. On a
hunch, see if this helps:

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

Thank for you reply. I forgot the problem. My problem is the activex dll
can't fire the javascript event code. After I added the IProvideClassInfo2
interface support, the dll can fire the javascript event.

But now I have another problem. I want to create a thread in activex, and
fire the event in the thread just before thread exit. The activex can't fire
the event.

Here is my thread code:
CThreadParam* threadParam = (CThreadParam*)pParam;
auto_ptr<CThreadParam> paramPtr(threadParam);

HRESULT hr =
threadParam->pThis->HttpDownFile(threadParam->m_strRemote.c_str(),
threadParam->m_strLocal.c_str());
threadParam->pThis->Fire_DownloadComplete(hr,
threadParam->pThis->m_bstrInfo, threadParam->pThis->m_bstrDesc);

threadParam->pThis is the pointer of Component class.

Does it matter with thead model?

Have the thread post a custom message to the control's window, and fire
the event from that message's handler. You can't easily fire events
directly from the worker thread.

Hi Igore,

my application needs the second thread to fire the events. because here first thread is essentially IE's so i canot block it.
i am facing the same issue as Bucher faced.

Can you guide me how to fire events from the second thread?
